Methods: retrospective analysis was used. The subjects were 50 pregnant women in our hospital. All the subjects were informed and signed the consent form. According to different nursing intervention methods, the subjects were divided into observation group and control group to compare, analyze and record the actual nursing intervention effect data and information. Results: after practical research, analysis and observation, it can be found that the basin function of pregnant women in the observation group is good, and the effect of postpartum basin rehabilitation is obvious, which is significantly better than that of pregnant women in the control group. The data comparison has statistical significance (P < 0.05). Conclusion: rehabilitation treatment after natural delivery can improve the clinical effect, promote the early recovery of pelvic floor function and improve the quality of life of pregnant women.展开更多

Evidently, the study unearthed substantial correlations between prepregnancy body mass index, educational attainment, exposure to passive smoking, medical history, and other variables with the mode of delivery. Furthermore, a predictive nomogram model was formulated to accurately forecast the likelihood of cesarean section. These discernments equip pertinent authorities with the means to institute targeted screening and supportive measures for women contemplating pregnancy based on these identified factors. Moreover, provision of services such as prepregnancy counseling and clinical risk assessments could be instrumental in curbing the incidence of cesarean section.展开更多

Objective: To analyze the impact of delivery mode on morbidity in preterm infants weighing less than 1500 g. Results: Among 21,957 births, 81 were analyzed;53 were delivered vaginally, and 28 were delivered by cesarean section. The median maternal age, gestational age and body mass index among those delivered vaginally and by cesarean section were 20 years and 22.5 years, 27.6 weeks and 30.1 weeks, and 26.0 kg/m2 and 27.8 kg/m2, respectively. With respect to neonatal blood gas parameters, for those born vaginally and by cesarean section, the median pH was 7.32 and 7.24, the pCO2 was 41.5 mmHg and 51.1 mmHg, and the pO2 was 22.3 mmHg and 16 mmHg. The median fetal weight among those born by cesarean section and vaginally were 1180 g and 955 g, respectively. The median Apgar scores at the first and fifth minutes among those born by cesarean section and vaginally were 5.00 and 8.00 and 4.50 and 7.00, respectively. Conclusion: There was no significant difference between the results of vaginal and cesarean delivery for VLBW infants. Thus, further studies on this subject are needed.展开更多

Methods: 80 elderly patients admitted to our hospital between April 2021 and April 2022 were selected and divided into two groups, i.e. the control group and the experimental group. The number of patients in each group was 40. The routine obstetric nursing intervention mode was implemented for all patients, and the experimental group also needed the joint midwifery nursing intervention scheme. Next, the delivery mode and the changes of the delivery process of all elderly women need to be compared. Results: the natural delivery rate of the experimental group was 60.00%, which was significantly higher than that of the control group (35.00%). At the same time, the time of the first, second and third stages of labor in this group was also significantly shorter than that of the control group. The difference of the above indexes was prominent and had statistical significance (P 0.05). Conclusion: after receiving the midwifery nursing intervention program, the elderly parturients can greatly improve the natural delivery rate and significantly shorten the labor process, which has certain positive significance for the smooth delivery and is worthy of being widely implemented in the clinic.展开更多

Methods: retrospective analysis was mainly adopted. In terms of research subjects, 160 cases of puerpera collected in our hospital from February 2017 to August 2018 were selected and divided into two groups according to the principle of contrastive analysis: the control group and the observation group, among which the control group adopted traditional delivery nursing measures, and the observation group took comprehensive pain reducing delivery nursing measures in terms of delivery mode and pain control during labor. Results: the clinical nursing effect of the observation group was higher than that of the control group, and the acceptance degree of the comprehensive pain relief delivery nursing measures was higher in the observation group. Conclusion: through systematic research and analysis, it can be found that the pregnant women in the observation group have a high acceptance of comprehensive pain relief delivery nursing measures, and have obvious "pain relief" effect, which is also one of the main reasons for the high acceptance of pregnant women in the observation group, while the pain of pregnant women in the control group has not been well relieved. This shows that the traditional nursing measures can not meet the nursing requirements and needs of pregnant women, and the follow-up of comprehensive pain relief delivery nursing measures is also worthy of great promotion and adoption in clinical obstetrics.展开更多

Methods: A retrospective cohort study of nulliparous parturients who gave birth in Vasternorrland County, Sweden, over a 2-year period between 2015 and 2016. Neonatal outcomes (Apgar score at 5 min and umbilical cord arterial blood gases), maternal outcomes (perineal injury, total bleeding volume and maternal satisfaction with birth) and labour parameters (mode of delivery and the durations of labour and postpartum hospital stay) were evaluated. Results: The study cohort consisted of 1449 women with singleton pregnancies. Patients were divided into two groups according to whether during labour they were administered epidural analgesia using bupivacaine and sufentanil (EDA group, n = 615) or not (non-EDA group, n = 834). The rate of assisted vaginal delivery was significantly higher in the EDA group than in the non-EDA group (15.6% and 11.3%, respectively, p < 0.05), whereas the rates of caesarean section were similar. The duration of the active phase of labour was significantly longer in the EDA group than in the non-EDA group (489 ± 217 min versus 371 ± 210 min, respectively, p < 0.001). The Apgar score at 5 min and umbilical cord blood pH were lower and the base deficit greater in the EDA group (p < 0.001, p < 0.001 and p < 0.01, respectively). Bleeding volume was similar between the groups after adjusting for gestational age. Women in the EDA group were more satisfied with their labour experience, as measured by the visual analogue scale (p Conclusion: The results of this study suggest that EDA affects delivery and neonatal-maternal outcomes negatively, but increases the mother’s satisfaction with labour.展开更多

Methods: 60 cases of premature birth with reproductive tract infection were divided into A (n=30) and B (n=30) and studied from September 2020 to September 2021 to give routine clinical treatment, group B added antibiotics according to the results of bacterial culture and drug sensitivity test to compare the treatment effects and differences between the two groups. Results The incidence of neonatal pneumonia and adverse maternal pregnancy outcomes were lower in group B than in group A, which were both statis significant (P <0.05). Conclusion: using antibiotics to the treatment of premature pre-mature birth combined with reproductive tract infection can improve the quality of delivery and reduce the adverse effects on mother and baby.展开更多

Methods: 148 selected parturients who gave birth in the hospital maternity department voluntarily participated in the experimental study, and all gave birth between March 2021 and March 2022. The selected parturients were divided into two groups by computer sampling, namely, the conventional group (74 cases) and the new model group (74 cases) respectively. The delivery methods of selected parturients were analyzed and compared between groups. The labor process and postpartum hemorrhage rate of selected parturients were analyzed and compared between groups. The negative emotional state of selected parturients before and after intervention was analyzed and compared between groups. Results: under different nursing intervention modes, the proportion of pregnant women willing to give birth naturally in the new mode group was 86.49%(64/74), while the proportion actually adopting natural delivery was 85.14%(63/74), which was higher than 56.76%(42/74) and 59.46%(44/74) in the conventional mode group respectively. The intervention effect in the new mode group was better. Under different nursing intervention modes, the labor stage and postpartum hemorrhage rate in the new mode group were (674.39±148.57) min and 0.00%(0/74), which were better than those in the conventional group (854.78±162.43) min and 8.11%(6/74). After using different intervention modes, the SAS and SDS scores of the two groups of parturients showed a decreasing trend after the intervention compared with before the intervention, while the negative emotion score of the patients in the new mode group showed a more significant decreasing trend after the intervention (P0.05). Conclusion: The new mode of obstetrical nursing intervention for parturients can effectively improve the parturients willingness to give birth naturally and thus increase the rate of natural childbirth. Moreover, this intervention mode can also shorten the parturition process and reduce the occurrence of postpartum hemorrhage.展开更多

文摘BACKGROUND Gestational diabetes mellitus(GDM)refers to abnormal glucose tolerance during pregnancy,and it is often accompanied by obvious changes in glucose and lipid metabolism,and associated with adverse pregnancy outcomes.The incidence of fetal distress,polyhydramnios,puerperal infection,premature delivery,and macrosomia in pregnant women with GDM are higher than in those without GDM.AIM To analyze the relationship between age of pregnant women with GDM and mode of delivery and neonatal Apgar score.METHODS A total of 583 pregnant women with GDM who delivered in the Department of Obstetrics at our hospital between March 2019 and March 2022 were selected.Among them,377 aged<35 years were selected as the right age group and 206 aged>35 years were selected as the older group.The clinical data of the two groups were collected,and the relationship between age of the pregnant women with GDM and mode of delivery,maternal and neonatal outcomes,and neonatal Apgar score were compared.In the older group,159 women were classed as the adverse outcome group and 47 as the good outcome group according to whether they had adverse maternal and infant outcomes.The related factors of adverse maternal and infant outcomes were analyzed through logistic regression.RESULTS The number of women with assisted pregnancy,≤37 wk gestation,≥2 pregnancies,one or more deliveries,and no pre-pregnancy blood glucose screening in the older group were all higher than those in the right age group(P<0.05).The natural delivery rate in the right age group was 40.85%,which was higher than 22.33%in the older group(P<0.05).The cesarean section rate in the older group was 77.67%,which was higher than 59.15%in the right age group(P<0.05).The older group had a higher incidence of polyhydramnios and postpartum hemorrhage,and lower incidence of fetal distress than the right age group had(P<0.05).There was no significant difference in neonatal weight between the two groups(P>0.05).The right age group had higher Apgar scores at 1 and 5 min than the older group had(P<0.05).Significant differences existed between the poor and good outcome groups in age,education level,pregnancy mode,≤37 wk gestation,number of pregnancies,and premature rupture of membranes(P<0.05).Logistic regression showed that age,education level and premature rupture of membranes were all risk factors affecting the adverse outcomes of mothers and infants(P<0.05).CONCLUSION Delivery mode and Apgar score of pregnant women with GDM are related to age.Older age increases the adverse outcome of mothers and infants.
文摘BACKGROUND Augmentation cystoplasty,first described by Mikulicz in 1899 involves segments of bowel,stomach or mega-ureter to increase bladder capacity in those with inadequate bladder function or lack of detrusor compliance.The most widely used bowel segment is a detubularised patch of ileum.When ileum is not suitable for augmentation,sigmoid colon is the alternative.However,only eight pregnancies after sigmoidocystoplasty have been reported without detail and clinicians may be uncertain about the effects of sigmoidocystoplasty on reproductive health and pregnancy.CASE SUMMARY We followed the patient from gestational week 32+3 until 6 wk after delivery.During pregnancy,our patient suffered urinary tract infection twice and had to undergo percutaneous nephrostomy drainage due to progressive hydronephrosis.Despite a dense adhesion between the uterus and neobladder,we were able to deliver a healthy baby by cesarian section in the presence of the attending urologist.CONCLUSION Augmentation cystoplasty-afflicted women can have a healthy reproductive life.Certain perioperative measures may be advisable to avoid serious surgical complications.
文摘<strong>Background:</strong><span><span><span style="font-family:""><span style="font-family:Verdana;"> Meconium stained amniotic fluid (MSAF), especially observed before term, is considered a sign of fetal jeopardy. Although many studies characterized this condition and associated it with delivery mode, data is lacking in this area, Saudi Arabia. Thus, we attempted to study it. </span><b><span style="font-family:Verdana;">Methods:</span></b><span style="font-family:Verdana;"> All data were retrieved from pregnant patients with MSAF who delivered at King Abdul, Saudi Arabia, from January 2015 to December 2018. </span><b><span style="font-family:Verdana;">Results:</span></b><span style="font-family:Verdana;"> 758 showed MSAF, of which 83% had vaginal delivery, whereas remaining 17% had an emergency caesarean section. Of them, 32 (4.2%) infants developed meconium aspiration syndrome, and 7 (21.8%) were admitted to the NICU. </span><b><span style="font-family:Verdana;">Conclusion:</span></b><span style="font-family:Verdana;"> It was reconfirmed that MSAF is associated with a newborn risk, especially meconium aspiration syndrome.

文摘Objective: to explore the effect of clinical outpatient mode of prenatal examination on the delivery mode and labor course of puerpera. Methods: retrospective study, 48 cases of pregnant women who received prenatal examination in our hospital from 2020.3 to 2021.7 were selected and randomly divided into groups, including control group 25 routine intervention, observation group 23 cases of prenatal examination outpatient mode, observe the two groups of maternal delivery mode and labor process. Results: the rate of maternal natural childbirth in the observation group was as high as 73.91%, significantly higher than that in the control group (40.00%), and the puerpera in the observation group was shorter, the data of the two groups were compared, P < 0.05. Conclusion: the implementation of out-patient prenatal examination can shorten the time of labor and increase the rate of natural childbirth.
文摘Objective: to consider the changes of delivery mode and labor process in elderly puerperae receiving midwifery nursing intervention. Methods: 80 elderly patients admitted to our hospital between April 2021 and April 2022 were selected and divided into two groups, i.e. the control group and the experimental group. The number of patients in each group was 40. The routine obstetric nursing intervention mode was implemented for all patients, and the experimental group also needed the joint midwifery nursing intervention scheme. Next, the delivery mode and the changes of the delivery process of all elderly women need to be compared. Results: the natural delivery rate of the experimental group was 60.00%, which was significantly higher than that of the control group (35.00%). At the same time, the time of the first, second and third stages of labor in this group was also significantly shorter than that of the control group. The difference of the above indexes was prominent and had statistical significance (P 0.05). Conclusion: after receiving the midwifery nursing intervention program, the elderly parturients can greatly improve the natural delivery rate and significantly shorten the labor process, which has certain positive significance for the smooth delivery and is worthy of being widely implemented in the clinic.
文摘Objective: To explore the application value of personalized nursing intervention in obstetric pregnant women's nursing.Methods: 112 pregnant women in our hospital from February 2019 to February 2021 were randomly divided into two groups.The control group applied routine nursing, and the study group applied personalized nursing intervention on this basis.Results: the satisfaction rate of the study group was higher than that of the control group (P < 0.05);The length of production and hospitalization in the study group were longer than those in the control group, and the amount of bleeding was lower than that in the control group (P < 0.05).Conclusion: the effect of personalized nursing intervention in obstetric pregnant women's nursing is better, which can effectively shorten the length of delivery and hospitalization, reduce the amount of bleeding and improve satisfaction.

文摘Objective:Pelvic floor sensory training is commonly used in clinical practice for the treatment of stress urinary incontinence(SUI);however,there is a lack of comparative studies evaluating pelvic floor sensation between women with SUI and healthy controls.Additionally,normative data for two-point discrimination thresholds in the female pelvic floor region remain scarce.This study aims to compare the results of 4 sensory tests in the pelvic floor region between women with mild SUI and healthy women,in order to provide reference values for two-point discrimination thresholds in this area.Methods:From April 1 to October 30,2023,108 healthy women[(32.5±3.6)years]and 90 women with mild SUI[(32.9±3.3)years]were recruited from the Third Xiangya Hospital,Central South University.Participants underwent 4 sensory tests in the pelvic floor region:Two-dot discrimination,weight perception,shape recognition,and 9-grid localization.The results were compared between the 2 groups.Results:Compared with healthy women,those with mild SUI had lower sensitivity and higher thresholds in 2-dot discrimination tests in the pelvic floor region(all P<0.001).No significant differences were found between groups in weight perception,shape recognition,or grid localization tests(P>0.05).Conclusion:Women with mild stress urinary incontinence have impaired two-point discrimination ability in the pelvic floor region.
文摘Objective: to analyze the effect of prenatal nursing intervention in reducing the cesarean section rate of pregnant women. Methods: 90 cases of pregnant women were randomly divided into 45 cases in each group to compare the nursing effect. Results: the cesarean section rate, labor duration and psychological status score of the observation group were better than those of the control group, P < 0.05. Conclusion: prenatal nursing intervention is effective in pregnant women and can be popularized.
文摘Objective: This paper mainly makes a systematic research and Analysis on the specific effect of comprehensive pain reducing delivery nursing measures. Methods: retrospective analysis was mainly adopted. In terms of research subjects, 160 cases of puerpera collected in our hospital from February 2017 to August 2018 were selected and divided into two groups according to the principle of contrastive analysis: the control group and the observation group, among which the control group adopted traditional delivery nursing measures, and the observation group took comprehensive pain reducing delivery nursing measures in terms of delivery mode and pain control during labor. Results: the clinical nursing effect of the observation group was higher than that of the control group, and the acceptance degree of the comprehensive pain relief delivery nursing measures was higher in the observation group. Conclusion: through systematic research and analysis, it can be found that the pregnant women in the observation group have a high acceptance of comprehensive pain relief delivery nursing measures, and have obvious "pain relief" effect, which is also one of the main reasons for the high acceptance of pregnant women in the observation group, while the pain of pregnant women in the control group has not been well relieved. This shows that the traditional nursing measures can not meet the nursing requirements and needs of pregnant women, and the follow-up of comprehensive pain relief delivery nursing measures is also worthy of great promotion and adoption in clinical obstetrics.

文摘Aim: To evaluate the effect of epidural analgesia during labour on neonatal-maternal outcomes. Methods: A retrospective cohort study of nulliparous parturients who gave birth in Vasternorrland County, Sweden, over a 2-year period between 2015 and 2016. Neonatal outcomes (Apgar score at 5 min and umbilical cord arterial blood gases), maternal outcomes (perineal injury, total bleeding volume and maternal satisfaction with birth) and labour parameters (mode of delivery and the durations of labour and postpartum hospital stay) were evaluated. Results: The study cohort consisted of 1449 women with singleton pregnancies. Patients were divided into two groups according to whether during labour they were administered epidural analgesia using bupivacaine and sufentanil (EDA group, n = 615) or not (non-EDA group, n = 834). The rate of assisted vaginal delivery was significantly higher in the EDA group than in the non-EDA group (15.6% and 11.3%, respectively, p < 0.05), whereas the rates of caesarean section were similar. The duration of the active phase of labour was significantly longer in the EDA group than in the non-EDA group (489 ± 217 min versus 371 ± 210 min, respectively, p < 0.001). The Apgar score at 5 min and umbilical cord blood pH were lower and the base deficit greater in the EDA group (p < 0.001, p < 0.001 and p < 0.01, respectively). Bleeding volume was similar between the groups after adjusting for gestational age. Women in the EDA group were more satisfied with their labour experience, as measured by the visual analogue scale (p Conclusion: The results of this study suggest that EDA affects delivery and neonatal-maternal outcomes negatively, but increases the mother’s satisfaction with labour.
文摘Objective: to investigate the clinical efficacy of antibiotics in treating premature fetal membrane rupture combined with reproductive tract infection. Methods: 60 cases of premature birth with reproductive tract infection were divided into A (n=30) and B (n=30) and studied from September 2020 to September 2021 to give routine clinical treatment, group B added antibiotics according to the results of bacterial culture and drug sensitivity test to compare the treatment effects and differences between the two groups. Results The incidence of neonatal pneumonia and adverse maternal pregnancy outcomes were lower in group B than in group A, which were both statis significant (P <0.05). Conclusion: using antibiotics to the treatment of premature pre-mature birth combined with reproductive tract infection can improve the quality of delivery and reduce the adverse effects on mother and baby.
文摘Objective: to analyze the application effect of the new obstetric care model in order to reduce the rate of cesarean section and explore its clinical application value. Methods: 148 selected parturients who gave birth in the hospital maternity department voluntarily participated in the experimental study, and all gave birth between March 2021 and March 2022. The selected parturients were divided into two groups by computer sampling, namely, the conventional group (74 cases) and the new model group (74 cases) respectively. The delivery methods of selected parturients were analyzed and compared between groups. The labor process and postpartum hemorrhage rate of selected parturients were analyzed and compared between groups. The negative emotional state of selected parturients before and after intervention was analyzed and compared between groups. Results: under different nursing intervention modes, the proportion of pregnant women willing to give birth naturally in the new mode group was 86.49%(64/74), while the proportion actually adopting natural delivery was 85.14%(63/74), which was higher than 56.76%(42/74) and 59.46%(44/74) in the conventional mode group respectively. The intervention effect in the new mode group was better. Under different nursing intervention modes, the labor stage and postpartum hemorrhage rate in the new mode group were (674.39±148.57) min and 0.00%(0/74), which were better than those in the conventional group (854.78±162.43) min and 8.11%(6/74). After using different intervention modes, the SAS and SDS scores of the two groups of parturients showed a decreasing trend after the intervention compared with before the intervention, while the negative emotion score of the patients in the new mode group showed a more significant decreasing trend after the intervention (P0.05). Conclusion: The new mode of obstetrical nursing intervention for parturients can effectively improve the parturients willingness to give birth naturally and thus increase the rate of natural childbirth. Moreover, this intervention mode can also shorten the parturition process and reduce the occurrence of postpartum hemorrhage.
文摘To editor:Traffic accidents are a leading cause of spinal cord injury,responsible for 43%of cases.As vehicle ownership rises in China,so do traffic accidents,affecting around 600,000 people annually.Among traffic accident-related spinal cord injuries,37%are isolated cervical spine injuries,with 50%of cervical fractures involving nerve damage and severe paralysis.The most affected age group is 25-29 years,with women making up 34%of these cases.1 Spinal cord injuries significantly impact patients’safety and quality of life,presenting unique challenges for women of reproductive age during pregnancy and childbirth.The 2021 International Standards classify spinal cord injuries into tetraplegia(cervical segments)and paraplegia(thoracic,lumbar,or sacral segments).2 Between January and July 2023,Peking University First Hospital’s Obstetrics and Gynecology Department treated a pregnant woman with tetraplegia from a traffic accident.Characteristics of patients with spinal cord injury during pregnancy and postpartum were summarized and the choice of delivery mode of these patients were analyzed in this correspondence.All data used in this study were approved by the ethics committee of Peking University First Hospital.Written informed consent was obtained from the patient for publication and will be provided upon request.
