Puerperal pyrexia and sepsis are among the leading causes of preventable maternal morbidity and mortality not only in developing countries but in developed countries as well. Most postpartum infections take place after hospital discharge, which is usually 24 hours after delivery. In the absence of postnatal follow-up, as is the case in many developing countries, many cases of puerperal infections can go undiagnosed and unreported. Besides endometritis (endomyometritis or endomyoparametritis), wound infection, mastitis, urinary tract infection, and septic thrombophlebitis are the chief causes of puerperal infections. The predisposing factors leading to the development of sepsis include home birth in unhygienic conditions, low socioeconomic status, poor nutrition, primiparity, anemia, prolonged rupture of membranes, prolonged labor, multiple vaginal examinations in labor, cesarean section, obstetrical maneuvers, retained secundines within the uterus and postpartum hemorrhage. Maternal complications include septicemia, endotoxic shock, peritonitis or abscess formation leading to surgery and compromised future fertility. The transmissions of infecting organisms are typically categorized into nosocomial, exogenous, and endogenous. Nosocomial infections are acquired in hospitals or other health facilities and may come from the hospital environment or from the patient's own flora. Exogenous infections come from external contamination, especially when deliveries take place under unhygienic conditions. Endogenous organisms, consisting of mixed flora colonizing the woman's own genital tract, are also a source of infection in puerperal sepsis. Aseptic precautions, advances in investigative tools and the use of antibiotics have played a major role in reducing the incidence of puerperal infections. Part II of this review describes the best management of wound infection, pelvic abscess, episiotomy infection, thrombophlebitis, mastitis, urinary tract infection, and miscellaneous infections.
Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader should be able to recall that world wide puerperal sepsis is a leading cause of maternal mortality, state that many of the predisposing factors are preventable, explain that both nosocomial infections as well as exogenous infections are serious factors, and relate that septic techniques and antibiotics can play a major role in reducing the incidence of puerperal infections.
产褥期发热和败血症不仅是发展中国家,也是发达国家可预防的孕产妇发病和死亡的主要原因之一。大多数产后感染发生在出院后,通常是分娩后24小时。在许多发展中国家,由于缺乏产后随访,许多产褥期感染病例可能未被诊断和报告。除了子宫内膜炎(子宫内膜肌炎或子宫内膜肌层炎),伤口感染、乳腺炎、尿路感染和脓毒性血栓性静脉炎是产褥期感染的主要原因。导致败血症发生的易感因素包括在不卫生条件下在家分娩、社会经济地位低、营养差、初产、贫血、胎膜早破、产程延长、分娩时多次阴道检查、剖宫产、产科操作、子宫内残留胎盘胎膜和产后出血。孕产妇并发症包括败血症、内毒素休克、腹膜炎或脓肿形成导致手术以及未来生育能力受损。感染源的传播通常分为医院感染、外源性感染和内源性感染。医院感染是在医院或其他卫生设施中获得的,可能来自医院环境或患者自身的菌群。外源性感染来自外部污染,尤其是在不卫生条件下分娩时。由定植于女性自身生殖道的混合菌群组成的内源性微生物也是产褥期败血症的感染源。无菌预防措施、检查工具的进步和抗生素的使用在降低产褥期感染发生率方面发挥了重要作用。本综述的第二部分描述了伤口感染、盆腔脓肿、会阴切开术感染、血栓性静脉炎、乳腺炎、尿路感染和其他感染的最佳管理方法。
