Methods： A questionnaire regarding the factors for pressure sores in critically ill surgical patients was created using a case control study with reference to the pertinent literature. After being exam- ined and validated by experts, the questionnaire was used to collect data about critically ill surgical patients in a grade A tertiary hospital. Among the 47 patients enrolled into the study, the 14 who developed nosocomial pressure sores were allocated to the pressure sore group, and the remaining 33 patients who met the inclusion criteria and did not exhibit pressure sores were allocated to the control group. Univariate and multivariate logistic regression analyses were employed to examine the differences in 22 indicators between the two groups in an attempt to identify the risk factors for pressure sores. Results： According to the univariate analyses, the maximum value of lactic acid in the arterial blood, the number of days of norepinephrine use, the number of days of mechanical ventilation, the number of days of blood purification, and the number of days of bowel incontinence were statistically greater in the pressure sore group than in the control group （P〈0.05）. The multivariate logistic regression analysis revealed that the number of days of norepinephrine use and the level of lactic acid in the arterial blood were high risk-factors for pressure sores （P〈0.05）. Conclusions： The best method for preventing and control pressure sores in surgical critically ill patients is to strongly emphasize the duration of the critical status and to give special attention to patients in a continuous state of shock. The adoption of measures specific to high-risk patient groups and risk factors, including the active control of primary diseases and the application of decompression measures during the treatment of the patients, are helpful for improving the quality of care in the prevention and control of pressure sores in critically ill patients.展开更多

In this study we compared the effects of curved and straight laryngoscope blades on severity and incidence of PST. METHOD: In this prospective randomized clinical trial we evaluated incidence and severity of PST in 147 ASA physical status I–II, aged 18 – 62 y (group Miller, n = 71), (group Macintosh, n = 76) following intubation with Miller and Macintosh laryngoscope blades by using Visual Analog Scale (VAS). RESULTS: The overall incidence of PST in our study was 35.4% (Macintosh group = 39.5% and in Miller group = 31% and P = 0.829). The incidence of PST was not statistically different between two kinds of laryngoscope blades and the mean rank of pain score was not statistically different in recovery room and up to 48 hours after surgery. CONCLUSIONS: Our study showed these types of laryngoscope blade had not association with incidence and severity of PST. .展开更多

Participants were then randomized into 3 groups： 14% Plai cream, 7% Plai cream and placebo cream. Two grams of the cream（strips of 5-cm long） were gently rubbed into the quadriceps muscles for 5 min immediately following the exercise and every 8 h thereafter for 7 d in all groups. Muscle soreness, muscle strength, jump height, thigh circumference and creatine kinase were measured before and after eccentric exercise.RESULTS： Compared to the placebo cream the 14% Plai cream substantially reduced muscle soreness over the 7 d by –82%（95% CI = –155% to –6%, P = 0.03）, but had similar muscle soreness effects to 7% Plai cream（–34%, –96% to 27%, P = 0.2）. Compared to the placebo cream the 7% Plai cream resulted in a small non-significant reduction in muscle soreness levels over the following 7 d（–40%, –116% to 36%, P = 0.3）. Compared to placebo cream there was little effect of Plai cream（7% or 14%） on muscle strength, jump height, thigh circumference or creatine kinase concentration. CONCLUSION： Using 14% Plai cream over a 7-day period substantially reduced muscle soreness symptoms compared to 7% Plai cream or a placebo cream. The authors suggest that the administration of 14% Plai cream is a useful alternative in the management of DOMS.TRIAL REGISTRATION： Thai Clinical Trial Registry TCTR20140215001.展开更多

However, several prevention approaches, including non-surgical and surgical management,are available. In flap surgery for pressure sores, a variety of flap types may be used;each offers certain benefits and some incidences of complications and recurrence. This study evaluated the versatility of the perforatorenhanced rhomboid flap technique for ischial sore construction.Methods: This prospective study was conducted in the Plastic Surgery Department of Fayoum University Hospital.The perforator-enhanced rhomboid flap technique was employed in 20 patients with ischial pressure sores who failed to respond to conservative treatment. A proper history was obtained and a preoperative arterial duplex was performed to determine the site of the prominent perforators for their preservation at the base of the flap.Postoperative follow-ups and evaluations were performed.Results: The mean age of the study group was 43.7 ± 13.1, ranging from 19 to 65 years. Moreover, 80% of the participants were males while 20% were female. The main etiology of the sores was paraplegia in 45% of cases.The mean surface area of sores was 24.8 ± 6.3 cm2. In 75% of cases, the color match of the flap was rated as excellent. Similarly, 70% of the patients rated flap thickness as excellent. In 55% of the cases, the scar appearance was deemed excellent. Overall satisfaction was reported as excellent by 40% of the patients, while only 5% reported poor satisfaction. Approximately, 10% of the cases were identified with seroma, and 30% had wound dehiscence of a mean size of 1.33 ± 0.98 cm and required around 6.8 ± 1.9 weeks to heal.Conclusion: The perforator-enhanced rhomboid flap technique is a versatile method for reconstructing ischial pressure sores owing to its technical ease, short operative time, reliable vascularity, aesthetic outcome, matching skin color, and short recovery time. The main limitations include large defects with large surface areas, lack of a nearby donor site for a rhomboid flap, and scarring from prior procedures around the sore.展开更多

The nursing staff adopted conventional methods to carry out the nursing observation of the patients in the control group. On this basis, combined with the non-invasive positive pressure ventilation pressure sore nursing intervention model, the nursing research of the observation group was carried out. Then, the occurrence probability of pressure sore and nursing satisfaction of the patients in the two groups were compared. For the two groups of patients' nursing satisfaction, the observation group patients' nursing satisfaction was 97.65%, significantly higher than the control group 80.00%, while the observation group's pressure sore incidence rate was 2.35%, the control group's pressure sore incidence rate was 21.18%, data comparison, the observation group's pressure sore incidence rate was significantly lower, the difference between the groups was statistically significant (p < 0.05). It can be seen from this that in order to do a good job in the nursing of critically ill patients with COPD, it is extremely critical for the nursing staff to adopt the non-invasive positive pressure ventilation pressure sore nursing mode. On the basis of keeping close contact with the patients, the occurrence rate of pressure sores can be fundamentally reduced, and the nursing satisfaction of the patients can be comprehensively improved.展开更多

Methods: 160 patients with skin sores were randomly divided into two groups with 80 cases in each group. The control group was given routine nursing, and the observation group was given high-quality skin nursing on the basis of the control group. The nursing effect (physical function index, physiological function index), negative emotion (SAS, SDS score) and nursing satisfaction were compared between the two groups. Results: after nursing, the scores of physical function index and physiological function index in the observation group were significantly higher than those in the control group, and the scores of SAS and SDS were significantly lower than those in the control group (P < 0.05).The nursing satisfaction of the observation group was significantly higher than that of the control group (P < 0.05).Conclusion: high quality skin care can significantly improve the physical and physiological functions of patients with skin sores, alleviate their negative emotions and improve their nursing satisfaction.展开更多

文摘Background Specific nutrients combined with exercise may prevent a loss of lean body mass and consequently prevent sarcopenia.We examined the effects of 2 weeks of supplementation with L-carnitine and a single dose of branched-chain amino acids(BCAAs)on energy metabolism and body composition before and after exercise and on post-exercise muscle soreness in healthy subjects.Methods A total of 12 young,untrained,healthy women were randomly assigned to two groups who received either 2 weeks of supplementation with L-carnitine(1000 mg/day)and a single dose of BCAAs plus 200 kcal energy(LCAR+BCAA group,n=6)or 200 kcal energy alone(control group,n=6)before 60 min of exercise.Energy substrate metabolism and body composition by bio-impedance were examined before and after exercise.Delayed-onset muscle soreness(DOMS)was evaluated by using a visual analogue scale for 3 days after exercise.Results Serum concentrations of free and acyl-L-carnitine in the LCAR+BCAA group were not significantly different from those in the control group.There were no significant differences in body composition before or after exercise between the two groups.Although serum free fatty acid levels 120 min after the oral ingestion of BCAAs were significantly lower in the LCAR+BCAA group than in the control group,there were no significant differences in serum free fatty acid levels immediately after and 60 min after exercise.DOMS for 3 days after exercise was lower in the LCAR+BCAA group than in the control group,but this difference was not significant.Conclusion Continuous supplementation with L-carnitine combined with a dose of BCAAs in young,untrained,healthy subjects caused a blunted response of stimulated lipolysis after exercise.
文摘For the critically ill patients with COPD, in order to do a good job of nursing, the article investigates the application effect of nursing intervention on pressure sore caused by non-invasive positive pressure ventilation. 170 patients in our hospital were selected and the staffs were randomly divided into control group and observation group with equal number of cases. The nursing staff adopted conventional methods to carry out the nursing observation of the patients in the control group. On this basis, combined with the non-invasive positive pressure ventilation pressure sore nursing intervention model, the nursing research of the observation group was carried out. Then, the occurrence probability of pressure sore and nursing satisfaction of the patients in the two groups were compared. For the two groups of patients' nursing satisfaction, the observation group patients' nursing satisfaction was 97.65%, significantly higher than the control group 80.00%, while the observation group's pressure sore incidence rate was 2.35%, the control group's pressure sore incidence rate was 21.18%, data comparison, the observation group's pressure sore incidence rate was significantly lower, the difference between the groups was statistically significant (p < 0.05).

文摘The preference for a specific head shape can be influenced by people's culture,religious beliefs and race.Modern Chinese people prefer a"talented"head shape,which is rounded and has a long profile.To obtain their preferred head shape,some parents try to change their neonates'sleeping position.Due to these forced sleeping positions,positional skull deformities,such as plagiocephaly,may be present during the first few months of life.In this article,we report two neonatal cases,of Hui nationality and Dongxiang nationality,with occipital pressure sores that were caused by using hard objects as pillows with the intention of obtaining a flattened occiput.The pressure sores were deep to the occipital bone and needed surgical management.These pressure sores caused wounds that were repaired by local skin flaps,after debridement,and the use of external constraints from a dense sponge-made head frame for approximately two weeks.One case recovered with primary healing after surgical operation.The other case suffered from a disruption of the sutured wound,and a secondary operation was performed to cover the wound.These occipital pressure sores are avoidable by providing guidance to the parents in ethnic minorities'area regarding the prevention,diagnosis and management of positional skull deformity.
