产后出血一直是导致我国孕产妇死亡的首要原因。近20年, 我国因产后出血导致的孕产妇死亡虽然已经大幅减少, 但仍有进一步下降的空间。产后出血导致孕产妇死亡的主要原因在于诊断和治疗的延迟, 错过抢救时机。继2009年《产后出血预防与处理指南(草案)》和2014年《产后出血预防与处理指南(2014)》发布之后, 中华医学会妇产科学分会产科学组联合中华医学会围产医学分会基于最新的产后出血研究进展, 再次对指南进行修订, 对产后出血的病因及高危因素、临床表现及诊断、预防及处理流程进行全面阐述, 并提出重要推荐。新版指南强调产后出血处理的"四早原则"——尽早呼救及团队抢救、尽早综合评估及动态监测、尽早针对病因止血和尽早容量复苏及成分输血, 避免错过抢救时机而导致孕产妇发生严重并发症甚至死亡。  相似文献

<正>尽管临床医师不断努力在实践中改进对产后出血的认识、预防、处理。但是在我国以及全球范围内,产后出血仍然是导致孕产妇死亡的首要因素[1,2]。1997年,国际妇产科联盟(FIGO)前主席Mamoud Fathalla在哥本哈根举办的第15届世界妇产联盟会议上针对当时严峻的孕产妇死亡状况发表讲话:“妇女并非因为绝症而死亡,只是全社会没有采取必要的措施去积极救治”。这一论调尤其适用于产后出血导致的孕产妇死亡。  相似文献

Objectives.?To examine the obstetric outcomes of our ‘low risk’ pregnant women under the midwife-led delivery care compared with those under the obstetric shared care.

Methods.?A retrospective cohort study compared outcomes of labor under midwife ‘primary’ care with those under obstetric shared care. The factors examined were: maternal age, parity, gestational age at delivery, length of labor, augmentation of labor pains, delivery mode, episiotomy, perineal laceration, postpartum hemorrhage, neonatal birth weight, Apgar score, and umbilical artery pH. In this study, pregnant women were initially considered ‘low risk’ at admission when they had no history of medical, gynecological, or obstetric problems and no complications during the present pregnancy.

Results.?There were 1031 pregnant women initially considered ‘low risk’ at admission. At admission, 878 of them (85%) requested to give birth under midwife care; however 364 of these women (42%) were transferred to obstetric shared care during labor. The average length of labor under the midwife ‘primary’ care was significantly longer than that under the obstetric shared care. However, there were no significant differences in the rate of prolonged labor (≥24?h). There were no significant differences in other obstetric or neonatal outcomes between the two groups.

Conclusions.?There was no evidence indicating that midwife ‘primary’ care is unsafe for ‘low risk’ pregnant women. Therefore, midwifery care is recommended for ‘low risk’ pregnant women.  相似文献

ABSTRACT: Background: Hemorrhage and hypertensive disorders are major contributors to death after delivery in developing countries. The GIRMMAHP Initiative was designed to describe the actual delivery care in five Latin American countries and to educate and motivate clinical staff at 17 hospitals with the purpose of implementing their own clinical practice guidelines to prevent postpartum hemorrhage. Methods: A multicountry education intervention was developed in four consecutive stages, using two analyses: (a) an observational study of the clinical records in eight teaching and nine nonteaching hospitals and (b) a study of the long‐term changes measured 12 months after completion of an education intervention and writing a local clinical guideline. Results: Data from 2,247 pregnant women showed that only 23.3 percent had an active management of the third stage of labor and that 22.7 percent received no prenatal care visit. These data were used to prepare local clinical practice guidelines in each participant hospital. The proportion of active management increased to 72.6 percent of deliveries at 3 months and 58.7 percent 1 year later. Use of oxytocin during the third stage of labor increased to 85.9 percent of included deliveries. The proportion of women who had postpartum hemorrhage decreased from 12.7 percent at baseline to 5 percent at 1 year after the intervention. Conclusions: An education intervention and discussion of actual clinical practice problems with health professionals and their involvement in drafting clinical guidelines helped improve health care quality and practitioners’ adherence to these guidelines.

Purpose

To evaluate whether cesarean delivery (CD) indication, labor status, and other primary CD characteristics affect the risk for uterine rupture in subsequent deliveries.

Methods

A case–control study of women attempting trial of labor after cesarean (TOLAC) in a single, tertiary, university-affiliated medical center (2007–2016). Deliveries complicated by uterine rupture were matched to successful vaginal birth after cesarean (VBAC) deliveries in a 1:3 ratio. Indication, labor status and post-partum complications (postpartum hemorrhage and postpartum infection) at primary CD were compared between study and control group.

Results

During study period, there were 75,682 deliveries, of them, 3937 (5.2%) were TOLAC. Study group included 53 cases of uterine rupture at TOLAC and 159 women with successful VBAC. Women in study group had significantly lower rates of previous VBAC (15.1 vs. 28.9%, p?=?0.047). Rate of postpartum complications at primary CD was significantly higher in women with TOLAC complicated by uterine rupture (7.5 vs. 1.9%, respectively, p?=?0.042). Utilizing the multivariate logistic regression analysis, postpartum complications remained an independent risk factor for uterine rupture in the following TOLAC (aOR 4.07, 95% CI 1.14–14.58, p?=?0.031).

Conclusion

Postpartum hemorrhage and infection, in primary CD, seem to be associated with increased risk for uterine rupture during subsequent TOLAC.

OBJECTIVE: To estimate whether the length of the third stage of labor is correlated with postpartum hemorrhage. METHODS: In this prospective observational study women delivering vaginally in a tertiary obstetric hospital were assessed for postpartum hemorrhage. All women were actively managed with the administration of oxytocin upon delivery of the anterior shoulder. Blood loss was measured at each delivery in collecting devices, and drapes and sheets were weighed to calculate the blood loss at each vaginal delivery. Postpartum hemorrhage was defined as more than 1,000 mL blood loss or hemodynamic instability related to blood loss requiring a blood transfusion. RESULTS: During a 24-month period there were 6,588 vaginal deliveries in a single tertiary obstetric hospital, and postpartum hemorrhage occurred in 335 of these (5.1%). The median length of the third stage of labor was similar in women having and those not having a postpartum hemorrhage. The risk of postpartum hemorrhage was significant at 10 minutes, odds ratio (OR) 2.1, 95% confidence interval (CI), 1.6-2.6; at 20 minutes, OR 4.3, 95% CI 3.3-5.5; and at 30 minutes OR 6.2, 95% CI 4.6-8.2. The best predictor for postpartum hemorrhage using receiver operating characteristic curves was 18 minutes. CONCLUSION: A third stage of labor longer than 18 minutes is associated with a significant risk of postpartum hemorrhage. After 30 minutes the odds of having postpartum hemorrhage are 6 times higher than before 30 minutes. LEVEL OF EVIDENCE: III.  相似文献

Approximately 529,000 women die from pregnancy-related causes annually and almost all (99%) of these maternal deaths occur in developing nations. One of the United Nations' Millennium Development Goals is to reduce the maternal mortality rate by 75% by 2015. Causes of maternal mortality include postpartum hemorrhage, eclampsia, obstructed labor, and sepsis. Many developing nations lack adequate health care and family planning, and pregnant women have minimal access to skilled labor and emergency care. Basic emergency obstetric interventions, such as antibiotics, oxytocics, anticonvulsants, manual removal of placenta, and instrumented vaginal delivery, are vital to improve the chance of survival.  相似文献
