Method Eighty elderly patients with stable chronic obstructive pulmonary disease were divided randomly into an acupuncture group and a drug group, with forty cases in each group. The patients in the acupuncture group were treated with warming needle moxibustion on specific acupoints. Main acupoints include Zusanli （足三里 ST 36）, Feishu （肺俞 BL 13） and Dingchuan （定喘 EX-B 1）. Matching acupoints include Gaohuang （膏肓 BL 43）, Xinshu （心俞 BL 15）, Dazhui （大椎 GV 14） and Fangmen （风门 BE 12）. The acupoints were punctured with even reinforcing and reducing method. Meanwhile, two moxa stick of warming needle moxibustion were applied separately at the acupoints at back and ST 36. The needles were retained for approximately 0.5 h each time. The treatment was given every other day, 3 times a week and the course of treatment was 8 weeks. Patients in the drug group were treated by seretide inhalation （50 μg salmeterol and 250 μg fluticasone propionate）, twice a day for 8 weeks. The improvement in pulmonary function and the symptom of chills and fever were compared between the two groups. Results After treatment, pulmonary function indices [forced expiratory volume in one second （FEV1）, forced expiratory volume in one second to forced vital capacity （FEVl/FVC）, forced expiratory volume in one second to predicted value ratio （FEV1%） and peak expiratory flow （PEF）] of the patients in both groups were improved significantly compared with that before treatment （P〈0.05）. There was no statistically significant difference between the two groups （all P〉0.05）. Improvement in comprehensive scores of the symptom of chill and fever in the acupuncture group was significantly superior to that in the drug group after 4 and 8 weeks of the treatment, respectively （P〈0.05）. Conclusion Warming needle moxibustion was obviously effective on the improvement in pulmonary function of elderly patients with stable chronic obstructive pulmonary disease.展开更多

To investigate the changes and influencing factors of early postoperative pulmonary functionof thoracotomy.Methods. Pre-and early postoperative pulmonary function was studied in 64 consecutive cases withoptimal thoracotomy. Pain assessment was done before pulmonary function test, and the chief complaintsof patients were recorded after the procedure. The changing curves of pulmonary function were done andthe differences associated with groups, surgical styles, pain assessment, epidural analgesia, chief com-plaint and preoperative conditions were analyzed.Results. Pulmonary function was severely lowered to about 40% of the base line on the first day,and it was rehabilitated to about 60% of the base line on the eighth day. There was a greater gradienton the recovery curve on the 3rd and 4th days. Epidural analgesia was able to improve pain relaxationand pulmonary function in some degree. Single-factor analysis showed that postoperative pain, postopera-tive day and surgical style were the significant influencing factors for early postoperative pulmonary func-tion. By multiple-factor analysis, preoperative pulmonary function, age and postoperative pain were themain factors, while surgical style had only weak effect on it.Conclusions. Early postoperative pulmonary function is severely impaired by thoracotomy. It rehabili-tate gradually with time. Improvement of preoperative pulmonary function, reducing surgical procedure in-juries, especially injury to respiratory muscle system, and enough postoperative pain relief are the mostimportant means that would reduce pulmonary function impairment and consequently reduce postoperativepulmonary complications.展开更多

MethodsTwenty infants with VSD were enrolled in the study fromJan. to Dec.2004. They were divided into two groups: pulmonary hypertension group and non-pulmonary hypertension group, ten infantsrespectively. Pulmonary function parameters were measured before CPB and 3, 6, 9, 12, 15, 18, 21, 24h after CPB, the following datawere recorded: duration for mechanical ventilation (Tmv) and staying in the cardiac intensive care unit (Tcicu) after cardiac surgery.Results Before CPB, the pulmonary function parameters in non-pulmonary hypertension group were more superior than in pulmonary hy-pertension group (P<0.01). By contraries, the pulmonary function parameters in every time stage after CPB statistically significant de-creased in non-pulmonary hypertension group (P<0.05), especially at 6, 9, and 15h after CPB (P<0.01). In pulmonary hyperten-sion group, the pulmonary function parameters in 3h after CPB were more improved than before CPB, though there was no statistical sig-nificance. But they had statistically significant decreased at9, 12, 15h after CPB (P<0.05). There was a similar change in pulmonaryfunction between two groups at 21, 24h after CPB. Conclusion Exposure to CPB adversely affects pulmonary function after surgicalrepair of VSD in infants. We consider that the benefits of the surgical correction in infants with pulmonary hypertension outweight the neg-ative effects of CPB on pulmonary function. We should improve cardiac function to avoid the presence of the nadir trough in pulmonaryfunction. The infants with pulomonary hypertension also have ability to wean from mechanical ventilation as soon as possible, if the hemo-dynamics is stable, and without the responsive pulmonary hypertension or pulmonary hypertension crisis after surgical repair.展开更多

MEDLINE, EMBASE and Cochrane Central Register of clinical trials were systematically searched until January 2017 for RCTs of statins. Only trials with COPD patients were included. The I2 statistic was used to measure heterogeneity between trials and calculated mean differences for pulmonary function parameters with fixed-effect meta-analysis. Eight eligible studies with 534 participants were identified. Statin therapy had no remarkable influence on FEV1 （SMD -0.01, 95% CI -0.204 to 0.184, 12 = 0.0%, P = 0.922, n = 409）, FEV1/FVC （SMD 0.163, 95% CI -0.044 to 0.369, 12 = 0.0%, P = 0.123, n = 364）, 6MWD, heart rate or CRP. However, exercise time on treadmill was remarkably improved by statin therapy （SMD 1.271, 95% CI 0.930 to 1.612, 12 = 0.0%, P = 0.000, n = 160）. Subgroup analysis showed significant, ameliorative effect ofpravastatin on FEV1/FVC （SMD 0.362, 95% CI 0.049 to 0.674, 12 = 0.0%, P = 0.023）. The results of this meta-analysis showed non-significant effect of statins on pulmonary function in COPD patients. Based on the studies reviewed, it is not recommended to prescribe statins for COPD patients without CVD risk factors due to lack of clearly defined benefit.展开更多

[Methods] A total of 92 patients with AECOPD who came to Nanchong Chinese Medicine Hospital from March 2022 to February 2023 were selected for the study, and the intervention group (TCM nursing based on syndrome differentiation, 46 cases) and the conventional group (basic nursing, 46 cases) were selected for the study, and the pulmonary function and quality of life of the two groups were compared. [Results] Before nursing, there was no significant difference in levels of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and percentage of forced expiratory volume in one second to forced vital capacity (FEV1/FVC) between the intervention group and conventional group ( P >0.05). After 3 months of nursing, the levels of FVC, FEV1 and FEV1/FVC in the intervention group were higher than those in the conventional group ( P <0.05). Before nursing, there was no significant difference in the scores of health, emotion and social functions between the two groups ( P >0.05). At three months of nursing, the scores of health, emotion, and social functions in the intervention group were higher than those in the conventional group ( P <0.05). [Conclusions] The implementation of TCM nursing based on syndrome differentiation in patients with AECOPD can effectively improve the pulmonary function and quality of life of patients, and has significant clinical implementation value.展开更多

To evaluate the effectiveness of the perioperative intervention of LAMA/LABA, a randomized prospective trial was performed for the lung cancer patients receiving a lobectomy with normal pulmonary function and COPD. <strong>Methods:</strong> Based on the results of the preoperative pulmonary function test, 25 patients were diagnosed with COPD [% forced expiratory volume in 1 second (%FEV<sub>1</sub>) < 70%]. Thirty-seven patients were enrolled as non-obstructive patients (70% ≤ %FEV<sub>1</sub>), who were randomized into two groups, the LAMA/LABA (n = 19) and the Control group (n = 18). The LAMA/LABA and the COPD groups daily received inhaled LAMA (50 μg) and LABA (110 μg) for 1 week before surgery and for least 4 weeks after surgery. The Control group had no treatment of the dual bronchodilator. The actual values were measured during the perioperative pulmonary function at three points of the preoperative baseline, the postoperative 1 week and the postoperative 4 weeks;these changes and changed ratios were then calculated. The patient-reported outcomes of the quality of life (PRO-QOL) were evaluated by the Cancer Dyspnea Scale (CDS), the COPD assessment test, and the St. George’s Respiratory Questionnaire. <strong>Results:</strong> Regarding the value of FEV<sub>1</sub> at the baseline, that in the LAMA/LABA group was 79.2% ± 6.4% and that in the Control group was 80.9% ± 6.4%, but that in the COPD groups was 57.9% ± 8.7%;there was a significant difference between the COPD and the Control group (p < 0.0001). At the postoperative 1 week point, the FEV<sub>1</sub> value in the Control group was 1.3 ± 0.5 L and that in the LAMA/LABA group was 1.7 ± 0.5 L. On the other hand, that in the COPD group was 1.7 ± 0.5 L, which was significantly higher compared to that in the Control group (p = 0.0251 and p = 0.0369). The intervention of LAMA/LABA for the COPD and non-obstructive patients resulted in the less decreased degree of the pulmonary function in FEV<sub>1</sub> compared to that in the Control group. Based on the PRO-QOL by the CDS, the intervention of LAMA/LABA significantly reduced the total dyspnea in the LAMA/LABA group compared to that in the Control group (p = 0.0348). <strong>Conclusion:</strong> The perioperative intervention of LAMA/LABA should lead to maintaining the postoperative pulmonary function of the FEV<sub>1</sub> during the lobectomy with COPD and non-obstructive patients and the improvement of PRO-QOL.展开更多

At the same time,...<strong>Background:</strong> In an age of antiretroviral therapy, the life expectancy of children perinatally infected with Human Immunodeficiency Virus (HIV) has significantly increased. At the same time, however, pulmonary pathologies secondary to opportunistic infections have decreased thanks to increased diagnostics and access to antiretroviral therapy (ART). Despite this, in these children an immune dysregulation is maintained due to chronic infection. There is evidence that these patients have increased probability of presenting with abnormalities in pulmonary function, mainly with chronic obstructive clinical pictures (25% - 40% of perinatally infected adolescents display some anomaly in the spirometry), which predisposes them to increased risk of chronic pulmonary disease. Since lung development occurs mainly during infancy, patients perinatally infected with HIV may suffer consequences. This can be secondary to opportunistic infections, chronic inflammation due to the virus, and immunologic effects of ART, mainly in non-industrialized countries, where late diagnosis is frequent. <strong>Methodology:</strong> An analytical, observational, cross-sectional study was conducted at Roosevelt Hospital Pediatric infectious disease clinic, from January to December 2019. A sample of 76 patients was obtained, out of a population of 362 patients. A total of 62 subjects, who met the criterion of reproducibility in the spirometry, were analyzed. Results were analyzed with percentages and the association of variables using the chi-squared test (<em>χ</em><sup>2</sup>). <strong>Results:</strong> A decrease in pulmonary function was found in 34% of patients, mild obstructive pattern (16%) predominating. Significant association between basal viral load greater than 100,000 cp/ml and a decrease in Forced expiratory flow 25 - 75 (FEF 25-75) (<em>p</em> 0.046) and in relationship between forced expiratory volume and forced vital capacity (FEV1/ FVC <em>p</em> = 0.024) was observed, as well as a non-statistically significant relationship between advanced clinical stage at diagnosis and decreased pulmonary function. <strong>Conclusions:</strong> The prevalence of decreased pulmonary function related to advanced clinical stage and elevated basal viral load (>100,000 cps/ml) is higher than that reported in other studies (25%) and has an influence in the long-term decrease in pulmonary function.展开更多

Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to assess the potential inhalation hazards of ceramic proppant. 100 male workers from a producer of ceramic proppant were evaluated with pulmonary function test data collected and evaluated using The American Thoracic Society (ATS) acceptability criteria. A comparison group was selected from the Third National Health and Nutrition Examination Survey (NHANES III) spirometry laboratory subset. No pulmonary function deficits were found in the worker group in comparison to the NHANES III population. Mean FEV1 and FVC values in workers were 3.8 and 4.8 liters respectively, and were greater as compared to the NHANES III population of similar demographics. An FEV1/FVC ratio of less than 0.8, when compared to the NHANES III group, produced an odds ratio of 0.44 in worker group, indicating less risk of preclinical pulmonary dysfunction. Overall, exposure to ceramic proppant was not found to produce an adverse impact on pulmonary function in workers engaged in the manufacture of ceramic proppant.展开更多

Methods: a total of 72 patients with COPD admitted to our hospital from February 2020 to October 2021 were randomly divided into two groups. After the completion of the grouping, the patients in the control group (n36) received routine nursing from the department. The observation group (n36) received COPD rehabilitation nursing and self-management nursing, and the nursing effect was compared and analyzed after the patients were discharged. Results: the indexes of FEV1, FVC, 6MWD, self-management ability, disease cognition level, quality of life score and nursing satisfaction of the patients in the observation group were significantly better than those in the control group (P<0.05). Conclusion: in the clinical nursing process of COPD patients, self-management of rehabilitation nursing can improve the patients cardiopulmonary function and enhance the patients knowledge of COPD. At the same time, the patients body is healthier, the relationship with medical staff is improved, and the quality of life is improved, thus establishing a harmonious and friendly relationship. Therefore, it is worthy of clinical adoption and promotion.展开更多

Methods Twenty infants with VSD were enrolled in the study from Jan. to Dec. 2004. They were divided into two groups: pulmonary hypertension group and non-pulmonary hypertension group, ten infants respectively. Pulmonary function parameters were measured before CPB and 3, 6, 9, 12, 15, 18, 21, 24h after CPB, the following data were recorded- duration for mechanical ventilation ( Tmv) and staying in the cardiac intensive care unit ( Tcicu) after cardiac surgery. Results Before CPB, the pulmonary function parameters in non-pulmonary hypertension group were more superior than in pulmonary hypertension group (P < 0. 01). By contraries, the pulmonary function parameters in every time stage after CPB statistically significant decreased in non-pulmonary hypertension group (P <0. 05), especially at 6, 9, and 15h after CPB (P < 0. 01). In pulmonary hypertension group, the pulmonary function parameters in 3h after CPB were more improved than before CPB, though there was no statistical significance. But they had statistically significant decreased at 9, 12, 15h after CPB (P < 0. 05). There was a similar change in pulmonary function between two groups at 21, 24h after CPB. Conclusion Exposure to CPB adversely affects pulmonary function after surgical repair of VSD in infants. We consider that the benefits of the surgical correction in infants with pulmonary hypertension outweight the negative effects of CPB on pulmonary function. We should improve cardiac function to avoid the presence of the nadir trough in pulmonary function. The infants with pulomonary hypertension also have ability to wean from mechanical ventilation as soon as possible, if the hemodynamics is stable, and without the responsive pulmonary hypertension or pulmonary hypertension crisis after surgical repair.展开更多

Methods: 61 patients with rheumatic heart disease received by the cardiac surgery department of the hospital from April 11, 2020 to April 11, 2021 were grouped according to the time of elective heart surgery. 30 patients in the traditional group received traditional nursing intervention and 31 patients in the experimental group received respiratory function training. The postoperative pulmonary function and postoperative adverse reactions of the two groups were observed. Results: before nursing, the forced expiratory volume (FEV1), respiratory volume (FVC), the percentage of forced vital capacity in forced vital capacity (FEV1%) in the first second and the level of blood oxygen saturation (SaO2) in the two groups were highly homogeneous. After nursing, the levels of FEV1, FVC, FEV1% and SaO2 in the two groups were higher than those before nursing. FEV1, FVC The level of FEV1% was significantly higher than that of the traditional group, the statistical predictive value showed that there was specificity (P < 0.05), the level of SaO2 was slightly higher than that of the traditional group, and the statistical predictive value showed that there was no specificity (P > 0.05);The incidence of sputum cough and aspiration pneumonia in the experimental group was lower than that in the traditional group. The statistical prediction results showed that there was specificity (P < 0.05);The comparison of the satisfaction questionnaire between the two groups shows that the average score of the satisfaction questionnaire in the experimental group is higher than that in the traditional group, and the statistical prediction results suggest that there is specificity (P < 0.05). Conclusion: preoperative respiratory function training for rheumatic heart disease is helpful to the recovery of postoperative pulmonary function, reduce postoperative adverse reactions and improve patients satisfaction with medical services, which can be used as an important auxiliary measure before heart surgery.展开更多

文摘OBjECTIVE:To observe the relationship between reduced pulmonary function and regulatory T cells(Tregs)and helper T cells(Th)1/Th2 drift in a rat model of adjuvant arthritis(AA),and to study the impact of Xinfeng capsule(XFC)on pulmonary function and investigate the mechanism of action.METHODS:Forty rats were randomly divided into normal control group(NC),model control group(MC),Tripterygium glycosides tablet group(TPT),and XFC group,with 10 in each.Except for the NCgroup,AA was induced in all rats by intracutaneous injection of 0.1 mL Freund's complete adjuvant in the right paw.On the 19th day after modeling,the NC and MC groups were given physiological saline(0.9%),while the TPT and XFC groups were given TPT(10 mg/kg)and XFC(2.4 g/kg),once daily,respectively.Thirty days after administration,changes in paw swelling,arthritis index(AI),pulmonary function,levels of serumγ-interferon(IFN-γ)and interleukin(IL)-4,Tregs in peripheral blood,and IFN-γ,IL-4,Forkhead box transcription factor 3(FoxP3)in lung tissue were observed by enzyme-linked immunosorbent assay,flow cytometry,polymerase chain reaction,and western blot.RESULTS:Compared with the NC group,paw swelling,AI,IFN-γ,and Th1/Th2 were increased,and pulmonary function parameters,IL-4,FoxP3 were decreased significantly in the MC group(P<0.05 or P<0.01).Pulmonary function parameters,Treg,IL-4,FoxP3(and mRNA)were higher,and paw swelling,AI,and IFN-γ(and mRNA)were lower in the XFC group than those in the MC group.The XFC group was also much better than theTPT group in improving pulmonary function,FoxP3 mRNA,IFN-γ,IL-4,Th1/Th2,and IL-10(P<0.05 or P<0.01).CONCLUSION:Xinfeng capsule can improve pulmonary function by regulating the levels of Tregs,inhibiting the activation of Th1 to Th2 cells,inducing drift,maintaining cell immune suppression,correcting the imbalance of Th1/Th2,and reducing inflammatory mediators.
文摘BACKGROUND Lung cancer is a malignant tumor with high morbidity and mortality among cancers.Surgery is currently one of the primary methods of treating lung cancer.Although it can slow down the progression of the disease by removing the lesion,this invasive surgery inevitably damages the integrity of the patient’s chest.Moreover,the patient’s pulmonary function may have a low compensatory capacity after surgery,causing various respiratory diseases such as atelectasis,respiratory function decline,and even serious cardiovascular disease.All of these have great negative impacts on the surgical effect and the prognosis of patients.With the continuous exploration and development of nursing,continuous nursing and respiratory exercise nursing have been gradually applied in the nursing of patients after lung cancer surgery,and have achieved good nursing results.AIM To investigate the effect of continuous nursing combined with respiratory exercise nursing on the pulmonary function of postoperative patients with lung cancer.METHODS A total of 80 patients with lung cancer who underwent surgery in our hospital from January 2021 to December 2021 were selected as the study subjects.All subjects were randomly divided into the control group(n=40 cases)and the experimental group(n=40 cases).Patients with lung cancer in the control group were given conventional nursing after surgery,while the experimental group was given continuous nursing combined with respiratory exercise nursing based on conventional nursing.The recovery of pulmonary function and respiratory symptoms was observed before and after 3 mo of intervention in both groups.The pulmonary function parameters,blood gas analysis,MD Anderson Symptom Inventory-lung cancer module(MDASI-LC)scores,incidence of pulmonary complications,and Morisky compliance scores were compared between the two groups before and after 3 mo of intervention.RESULTS There was no significant difference in pulmonary function and blood gas analysis between the two groups before intervention(P>0.05).3 mo after the intervention,the pulmonary function parameters in the experimental group(SpO2,VC,MVV,FEV1,FEV1%pred,and FEV1/FVC)were higher than those in the control group,and the differences were statistically significant(P<0.05).There was no significant difference in blood gas analysis between the two groups before intervention(P>0.05).PaO2 in the experimental group was significantly higher than that in the control group,and PaCO_(2) was significantly lower than that in the control group 3 mo after the intervention.The difference had statistical significance(P<0.05).3 mo after the intervention,the MDASI score of respiratory symptoms in the experimental group was significantly lower than that in the control group(P<0.05),and the incidence of pulmonary complications was lower than that in the control group(P<0.05).In addition,the treatment compliance and nursing satisfaction of patients in the experimental group were higher than those in the control group,and the differences were statistically significant(P<0.05).CONCLUSION Continuous nursing combined with respiratory exercise nursing can significantly accelerate the recovery of respiratory function in postoperative lung cancer patients,reduce the incidence of postoperative complications of lung cancer as well as improve the treatment compliance of patients.
文摘Objective. To investigate the changes and influencing factors of early postoperative pulmonary functionof thoracotomy.Methods. Pre-and early postoperative pulmonary function was studied in 64 consecutive cases withoptimal thoracotomy. Pain assessment was done before pulmonary function test, and the chief complaintsof patients were recorded after the procedure. The changing curves of pulmonary function were done andthe differences associated with groups, surgical styles, pain assessment, epidural analgesia, chief com-plaint and preoperative conditions were analyzed.Results. Pulmonary function was severely lowered to about 40% of the base line on the first day,and it was rehabilitated to about 60% of the base line on the eighth day. There was a greater gradienton the recovery curve on the 3rd and 4th days. Epidural analgesia was able to improve pain relaxationand pulmonary function in some degree. Single-factor analysis showed that postoperative pain, postopera-tive day and surgical style were the significant influencing factors for early postoperative pulmonary func-tion. By multiple-factor analysis, preoperative pulmonary function, age and postoperative pain were themain factors, while surgical style had only weak effect on it.Conclusions. Early postoperative pulmonary function is severely impaired by thoracotomy. It rehabili-tate gradually with time. Improvement of preoperative pulmonary function, reducing surgical procedure in-juries, especially injury to respiratory muscle system, and enough postoperative pain relief are the mostimportant means that would reduce pulmonary function impairment and consequently reduce postoperativepulmonary complications.
文摘Objective To evaluate the effect of the cardiopulmonary bypass (CPB) on the pulmonary function in infants with or withoutpulmonary hypertension in congential ventricular septal defect (VSD). MethodsTwenty infants with VSD were enrolled in the study fromJan. to Dec.2004. They were divided into two groups: pulmonary hypertension group and non-pulmonary hypertension group, ten infantsrespectively. Pulmonary function parameters were measured before CPB and 3, 6, 9, 12, 15, 18, 21, 24h after CPB, the following datawere recorded: duration for mechanical ventilation (Tmv) and staying in the cardiac intensive care unit (Tcicu) after cardiac surgery.Results Before CPB, the pulmonary function parameters in non-pulmonary hypertension group were more superior than in pulmonary hy-pertension group (P<0.01). By contraries, the pulmonary function parameters in every time stage after CPB statistically significant de-creased in non-pulmonary hypertension group (P<0.05), especially at 6, 9, and 15h after CPB (P<0.01). In pulmonary hyperten-sion group, the pulmonary function parameters in 3h after CPB were more improved than before CPB, though there was no statistical sig-nificance. But they had statistically significant decreased at9, 12, 15h after CPB (P<0.05). There was a similar change in pulmonaryfunction between two groups at 21, 24h after CPB. Conclusion Exposure to CPB adversely affects pulmonary function after surgicalrepair of VSD in infants. We consider that the benefits of the surgical correction in infants with pulmonary hypertension outweight the neg-ative effects of CPB on pulmonary function. We should improve cardiac function to avoid the presence of the nadir trough in pulmonaryfunction. The infants with pulomonary hypertension also have ability to wean from mechanical ventilation as soon as possible, if the hemo-dynamics is stable, and without the responsive pulmonary hypertension or pulmonary hypertension crisis after surgical repair.

文摘In the current meta-analysis, we aimed to investigate the therapeutic effects of statins on pulmonary function in patients with chronic obstructive pulmonary disease （COPD）. MEDLINE, EMBASE and Cochrane Central Register of clinical trials were systematically searched until January 2017 for RCTs of statins. Only trials with COPD patients were included. The I2 statistic was used to measure heterogeneity between trials and calculated mean differences for pulmonary function parameters with fixed-effect meta-analysis. Eight eligible studies with 534 participants were identified. Statin therapy had no remarkable influence on FEV1 （SMD -0.01, 95% CI -0.204 to 0.184, 12 = 0.0%, P = 0.922, n = 409）, FEV1/FVC （SMD 0.163, 95% CI -0.044 to 0.369, 12 = 0.0%, P = 0.123, n = 364）, 6MWD, heart rate or CRP. However, exercise time on treadmill was remarkably improved by statin therapy （SMD 1.271, 95% CI 0.930 to 1.612, 12 = 0.0%, P = 0.000, n = 160）. Subgroup analysis showed significant, ameliorative effect ofpravastatin on FEV1/FVC （SMD 0.362, 95% CI 0.049 to 0.674, 12 = 0.0%, P = 0.023）. The results of this meta-analysis showed non-significant effect of statins on pulmonary function in COPD patients. Based on the studies reviewed, it is not recommended to prescribe statins for COPD patients without CVD risk factors due to lack of clearly defined benefit.

文摘[Objectives] To investigate the effects of TCM nursing based on syndrome differentiation on pulmonary function and quality of life in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). [Methods] A total of 92 patients with AECOPD who came to Nanchong Chinese Medicine Hospital from March 2022 to February 2023 were selected for the study, and the intervention group (TCM nursing based on syndrome differentiation, 46 cases) and the conventional group (basic nursing, 46 cases) were selected for the study, and the pulmonary function and quality of life of the two groups were compared. [Results] Before nursing, there was no significant difference in levels of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and percentage of forced expiratory volume in one second to forced vital capacity (FEV1/FVC) between the intervention group and conventional group ( P >0.05). After 3 months of nursing, the levels of FVC, FEV1 and FEV1/FVC in the intervention group were higher than those in the conventional group ( P <0.05). Before nursing, there was no significant difference in the scores of health, emotion and social functions between the two groups ( P >0.05). At three months of nursing, the scores of health, emotion, and social functions in the intervention group were higher than those in the conventional group ( P <0.05). [Conclusions] The implementation of TCM nursing based on syndrome differentiation in patients with AECOPD can effectively improve the pulmonary function and quality of life of patients, and has significant clinical implementation value.
文摘<strong>Background:</strong> A dual bronchodilator, long-acting anticholine drugs (glycopyrronium, LAMA) and the long running <em>β</em>-<sub>2</sub> stimulant (indacaterol, LABA), are effective for the treatment of chronic obstructive pulmonary disease (COPD). To evaluate the effectiveness of the perioperative intervention of LAMA/LABA, a randomized prospective trial was performed for the lung cancer patients receiving a lobectomy with normal pulmonary function and COPD. <strong>Methods:</strong> Based on the results of the preoperative pulmonary function test, 25 patients were diagnosed with COPD [% forced expiratory volume in 1 second (%FEV<sub>1</sub>) < 70%]. Thirty-seven patients were enrolled as non-obstructive patients (70% ≤ %FEV<sub>1</sub>), who were randomized into two groups, the LAMA/LABA (n = 19) and the Control group (n = 18). The LAMA/LABA and the COPD groups daily received inhaled LAMA (50 μg) and LABA (110 μg) for 1 week before surgery and for least 4 weeks after surgery. The Control group had no treatment of the dual bronchodilator. The actual values were measured during the perioperative pulmonary function at three points of the preoperative baseline, the postoperative 1 week and the postoperative 4 weeks;these changes and changed ratios were then calculated. The patient-reported outcomes of the quality of life (PRO-QOL) were evaluated by the Cancer Dyspnea Scale (CDS), the COPD assessment test, and the St. George’s Respiratory Questionnaire. <strong>Results:</strong> Regarding the value of FEV<sub>1</sub> at the baseline, that in the LAMA/LABA group was 79.2% ± 6.4% and that in the Control group was 80.9% ± 6.4%, but that in the COPD groups was 57.9% ± 8.7%;there was a significant difference between the COPD and the Control group (p < 0.0001). At the postoperative 1 week point, the FEV<sub>1</sub> value in the Control group was 1.3 ± 0.5 L and that in the LAMA/LABA group was 1.7 ± 0.5 L. On the other hand, that in the COPD group was 1.7 ± 0.5 L, which was significantly higher compared to that in the Control group (p = 0.0251 and p = 0.0369). The intervention of LAMA/LABA for the COPD and non-obstructive patients resulted in the less decreased degree of the pulmonary function in FEV<sub>1</sub> compared to that in the Control group. Based on the PRO-QOL by the CDS, the intervention of LAMA/LABA significantly reduced the total dyspnea in the LAMA/LABA group compared to that in the Control group (p = 0.0348). <strong>Conclusion:</strong> The perioperative intervention of LAMA/LABA should lead to maintaining the postoperative pulmonary function of the FEV<sub>1</sub> during the lobectomy with COPD and non-obstructive patients and the improvement of PRO-QOL.

文摘BACKGROUND Given current evidence,the effect of left ventricular assist device(LVAD)implantation on pulmonary function tests remains controversial.AIM To better understand the factors contributing to the changes seen on pulmonary function testing and the correlation with pulmonary hemodynamics after LVAD implantation.METHODS Electronic databases were queried to identify relevant articles.The summary effect size was estimated as a difference of overall means and standard deviation on a random-effects model.RESULTS A total of four studies comprising 219 patients were included.The overall mean forced expiratory volume in one second(FEV1),forced vital capacity(FVC)and diffusion lung capacity of carbon monoxide(DLCO)after LVAD implantation were significantly lower by 0.23 L(95%CI:0.11-0.34,P=00002),0.18 L(95%CI:0.03-0.34,P=0.02),and 3.16 mmol/min(95%CI:2.17-4.14,P<0.00001),respectively.The net post-LVAD mean value of the cardiac index was significantly higher by 0.49 L/min/m2(95%CI:0.31-0.66,P<0.00001)compared to pre-LVAD value.The pulmonary capillary wedge pressure and pulmonary vascular resistance were significantly reduced after LVAD implantation by 8.56 mmHg(95%CI:3.78-13.35,P=0.0004),and 0.83 Woods U(95%CI:0.11-1.55,P=0.02),respectively.There was no significant difference observed in the right atrial pressure after LVAD implantation(0.61 mmHg,95%CI:-2.00 to 3.32,P=0.65).Overall findings appear to be driven by studies using HeartMateII devices.CONCLUSION LVAD implantation might be associated with a significant reduction of the spirometric measures,including FEV1,FVC,and DLCO,and an overall improvement of pulmonary hemodynamics.
文摘Buitrago and colleagues should be commended on an excellent case report on the effective use of the robotic platform for a successful minimally invasive left lower lobectomy for a patient with biopsy proven squamous cell carcinoma.1 Despite a predicted postoperative forced expiratory volume in one second(ppoFEV1)of 23%and a preoperative diffusing capacity for carbon monoxide(DLCO)of 21%,the patient underwent a lobectomy without any intraoperative complications or evidence of disease at 15 months follow-up.Lymph node sampling was performed from 5 stations.The postoperative length of staywas not clearly stated.The authors made several interesting points about the impact of pulmonary function on postoperative outcomes,the oncological efficacy of lobectomy versus sublobar resections,and merits of roboticassisted thoracoscopic surgery(RATS)versus thoracotomy and conventional video-assisted thoracoscopic surgery(VATS).We would like to discuss these points in further detail based on the available evidence in the current literature.
文摘<strong>Background:</strong> In an age of antiretroviral therapy, the life expectancy of children perinatally infected with Human Immunodeficiency Virus (HIV) has significantly increased. At the same time, however, pulmonary pathologies secondary to opportunistic infections have decreased thanks to increased diagnostics and access to antiretroviral therapy (ART). Despite this, in these children an immune dysregulation is maintained due to chronic infection. There is evidence that these patients have increased probability of presenting with abnormalities in pulmonary function, mainly with chronic obstructive clinical pictures (25% - 40% of perinatally infected adolescents display some anomaly in the spirometry), which predisposes them to increased risk of chronic pulmonary disease. Since lung development occurs mainly during infancy, patients perinatally infected with HIV may suffer consequences. This can be secondary to opportunistic infections, chronic inflammation due to the virus, and immunologic effects of ART, mainly in non-industrialized countries, where late diagnosis is frequent. <strong>Methodology:</strong> An analytical, observational, cross-sectional study was conducted at Roosevelt Hospital Pediatric infectious disease clinic, from January to December 2019. A sample of 76 patients was obtained, out of a population of 362 patients. A total of 62 subjects, who met the criterion of reproducibility in the spirometry, were analyzed. Results were analyzed with percentages and the association of variables using the chi-squared test (<em>χ</em><sup>2</sup>). <strong>Results:</strong> A decrease in pulmonary function was found in 34% of patients, mild obstructive pattern (16%) predominating. Significant association between basal viral load greater than 100,000 cp/ml and a decrease in Forced expiratory flow 25 - 75 (FEF 25-75) (<em>p</em> 0.046) and in relationship between forced expiratory volume and forced vital capacity (FEV1/ FVC <em>p</em> = 0.024) was observed, as well as a non-statistically significant relationship between advanced clinical stage at diagnosis and decreased pulmonary function. <strong>Conclusions:</strong> The prevalence of decreased pulmonary function related to advanced clinical stage and elevated basal viral load (>100,000 cps/ml) is higher than that reported in other studies (25%) and has an influence in the long-term decrease in pulmonary function.
文摘Background:Asthma is a major non-communicable disease affecting both children and adult populations,characterized by inflammation and narrowing of airways.Hydrotherapy is a naturopathy treatment modality effectively used to manage bronchial asthma.This case series presents the immediate effect of one such hydrotherapy treatment hot fomentation on pulmonary function in bronchial asthma.Case presentation:Three women who had chief complaints of wheezing,sneeze and breathlessness due to chronic bronchial asthma.Hot fomentation over the inter-scapular region was given to the patient for a duration of 20 minutes.Pulmonary function test was performed using Recorders&Medicine Systems Pvt Ltd.Helios 401 before and immediately after the intervention to assess the efficacy of hot fomentation.Result:When compared to baseline,the pulmonary function’s parameters,such as forced vital capacity,forced expiratory volume in the first second,forced expiratory volume in the first second/forced vital capacity ratio,forced expiratory flow(25–75%)and peak expiratory flow showed significant improvement immediately after the fomentation.Conclusion:After 20 minutes of hot fomentation,significant improvement in pulmonary function was observed.Hot fomentation over the interscapular region,could thus be used to improve clinical outcomes in the management of bronchial asthma by improving pulmonary function and relieving acute symptoms.
文摘Workers involved in hydraulic fracking processes are exposed to various types of chemicals and dusts in their workplaces, such as proppants, which hold open the fissures created in the fracking process. Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to assess the potential inhalation hazards of ceramic proppant. 100 male workers from a producer of ceramic proppant were evaluated with pulmonary function test data collected and evaluated using The American Thoracic Society (ATS) acceptability criteria. A comparison group was selected from the Third National Health and Nutrition Examination Survey (NHANES III) spirometry laboratory subset. No pulmonary function deficits were found in the worker group in comparison to the NHANES III population. Mean FEV1 and FVC values in workers were 3.8 and 4.8 liters respectively, and were greater as compared to the NHANES III population of similar demographics. An FEV1/FVC ratio of less than 0.8, when compared to the NHANES III group, produced an odds ratio of 0.44 in worker group, indicating less risk of preclinical pulmonary dysfunction. Overall, exposure to ceramic proppant was not found to produce an adverse impact on pulmonary function in workers engaged in the manufacture of ceramic proppant.
文摘Objective: to explore the effect of rehabilitation nursing self-management on pulmonary function and quality of life of patients with COPD. Methods: a total of 72 patients with COPD admitted to our hospital from February 2020 to October 2021 were randomly divided into two groups. After the completion of the grouping, the patients in the control group (n36) received routine nursing from the department. The observation group (n36) received COPD rehabilitation nursing and self-management nursing, and the nursing effect was compared and analyzed after the patients were discharged. Results: the indexes of FEV1, FVC, 6MWD, self-management ability, disease cognition level, quality of life score and nursing satisfaction of the patients in the observation group were significantly better than those in the control group (P<0.05). Conclusion: in the clinical nursing process of COPD patients, self-management of rehabilitation nursing can improve the patients cardiopulmonary function and enhance the patients knowledge of COPD. At the same time, the patients body is healthier, the relationship with medical staff is improved, and the quality of life is improved, thus establishing a harmonious and friendly relationship. Therefore, it is worthy of clinical adoption and promotion.
文摘Objective To evaluate the effect of the cardiopulmonary bypass ( CPB) on the pulmonary function in infants with or without pulmonary hypertension in congential ventricular septal defect ( VSD). Methods Twenty infants with VSD were enrolled in the study from Jan. to Dec. 2004. They were divided into two groups: pulmonary hypertension group and non-pulmonary hypertension group, ten infants respectively. Pulmonary function parameters were measured before CPB and 3, 6, 9, 12, 15, 18, 21, 24h after CPB, the following data were recorded- duration for mechanical ventilation ( Tmv) and staying in the cardiac intensive care unit ( Tcicu) after cardiac surgery. Results Before CPB, the pulmonary function parameters in non-pulmonary hypertension group were more superior than in pulmonary hypertension group (P < 0. 01). By contraries, the pulmonary function parameters in every time stage after CPB statistically significant decreased in non-pulmonary hypertension group (P <0. 05), especially at 6, 9, and 15h after CPB (P < 0. 01). In pulmonary hypertension group, the pulmonary function parameters in 3h after CPB were more improved than before CPB, though there was no statistical significance. But they had statistically significant decreased at 9, 12, 15h after CPB (P < 0. 05). There was a similar change in pulmonary function between two groups at 21, 24h after CPB. Conclusion Exposure to CPB adversely affects pulmonary function after surgical repair of VSD in infants. We consider that the benefits of the surgical correction in infants with pulmonary hypertension outweight the negative effects of CPB on pulmonary function. We should improve cardiac function to avoid the presence of the nadir trough in pulmonary function. The infants with pulomonary hypertension also have ability to wean from mechanical ventilation as soon as possible, if the hemodynamics is stable, and without the responsive pulmonary hypertension or pulmonary hypertension crisis after surgical repair.
文摘Objective: to explore the effect of respiratory function training on improving pulmonary function in patients with rheumatic heart disease. Methods: 61 patients with rheumatic heart disease received by the cardiac surgery department of the hospital from April 11, 2020 to April 11, 2021 were grouped according to the time of elective heart surgery. 30 patients in the traditional group received traditional nursing intervention and 31 patients in the experimental group received respiratory function training. The postoperative pulmonary function and postoperative adverse reactions of the two groups were observed. Results: before nursing, the forced expiratory volume (FEV1), respiratory volume (FVC), the percentage of forced vital capacity in forced vital capacity (FEV1%) in the first second and the level of blood oxygen saturation (SaO2) in the two groups were highly homogeneous. After nursing, the levels of FEV1, FVC, FEV1% and SaO2 in the two groups were higher than those before nursing. FEV1, FVC The level of FEV1% was significantly higher than that of the traditional group, the statistical predictive value showed that there was specificity (P < 0.05), the level of SaO2 was slightly higher than that of the traditional group, and the statistical predictive value showed that there was no specificity (P > 0.05);The incidence of sputum cough and aspiration pneumonia in the experimental group was lower than that in the traditional group. The statistical prediction results showed that there was specificity (P < 0.05);The comparison of the satisfaction questionnaire between the two groups shows that the average score of the satisfaction questionnaire in the experimental group is higher than that in the traditional group, and the statistical prediction results suggest that there is specificity (P < 0.05). Conclusion: preoperative respiratory function training for rheumatic heart disease is helpful to the recovery of postoperative pulmonary function, reduce postoperative adverse reactions and improve patients satisfaction with medical services, which can be used as an important auxiliary measure before heart surgery.
文摘Objective: to study the application of lung function examination in the differential diagnosis of senile asthma and chronic obstructive pulmonary disease. Methods: 81 elderly patients with asthma or chronic obstructive pulmonary disease were screened. Patients with asthma alone were divided into group A (21 cases), patients with chronic obstructive pulmonary disease alone were divided into group B (21 cases), and patients with asthma combined with chronic obstructive pulmonary disease were divided into group C (21 cases). All patients in the 3 groups were examined for pulmonary function. Results: the respiratory indexes of group B and group C were significantly lower than that of group A, and lung function indexes among three groups were compared (P < 0.05). Conclusion: pulmonary function examination can accurately diagnose asthma and chronic obstructive pulmonary disease, so as to realize early detection and early treatment of disease, and help patients to improve the treatment effect. The diagnostic method of this kind of disease has high application value in clinic.
