米索前列醇预防剖宫产后出血344例临床观察

目的:观察米索前列醇预防剖宫产手术后出血的临床效果。方法:随机将有剖宫产手术指征的344例孕妇分为3组,分别为在胎儿娩出后给予米索前列醇200mg舌下含化(A组)、缩宫素静脉滴注及子宫肌层注射(B组)和对照组(C组,不给予任何药物),观察产后不同时间的出血量。结果:产后出血量及出血发生率A、B组均明显少于C组(P<0·05)。结论:米索前列醇对分娩后子宫具有较好的收缩作用,且给药方便、安全性较好。     

Mode of Delivery and the Survival of Macrosomic Infants in the United States, 1995–1999

ABSTRACT: Background: Although increases in perinatal mortality risk associated with fetal macrosomia are well documented, the optimal route of delivery for fetuses with suspected macrosomia remains controversial. The objective of this investigation was to assess the risk of neonatal death among macrosomic infants delivered vaginally compared with those delivered by cesarean section. Methods: Data were derived from the U.S. 1995–1999 Linked Live Birth‐Infant Death Cohort files and term (37–44 wk), single live births to United States resident mothers selected. A proportional hazards model was used to analyze the risk of neonatal death associated with cesarean delivery among 3 categories of macrosomic infants (infants weighing 4,000–4,499 g; 4,500–4,999 g; and 5,000+ g). Results: After controlling for maternal characteristics and complications, the adjusted hazard ratio for neonatal death associated with cesarean delivery among the 3 categories of macrosomic infants was 1.40, 1.30, and 0.85. Conclusions: Although cesarean delivery may reduce the risk of death for the heaviest infants (5,000+ g), the relative benefit of this intervention for macrosomic infants weighing 4,000–4,999 g remains debatable. Thus, policies in support of prophylactic cesarean delivery for suspected fetal macrosomia may need to be reevaluated. (BIRTH 33:4 December 2006)

临床科室工作量评价方法及其应用

目的：探讨测量、评价临床科室工作量的指标和方法，加强医院科室管理，促进效益评价与核算。方法：应用医院病案和报表资料，每月计算科室工作强度指数并进行排位，用相对比方法初步分析科室临床工作量和排位变动的状况。结果：选取了实际占用床位数、危重病人抢救次数、门急诊人次数、出会诊人次数、出院病人数5项指标，计算出各科室工作强度指数和排位，并对各科室工作量排位变动进行了比较。结论：临床工作量评价指标和方法的代表性、灵敏性和可靠性较好，实际评价效果也较客观地反映了各临床科室的实际工作量大小。     

Incidence of hospital-acquired infections associated with caesarean section

A retrospective cohort study was conducted to determine the incidence of post-caesarean infections in a Canadian community teaching hospital using computer algorithms designed for the diagnosis of nosocomial infections. Inferential chart review was done on 1335 women delivered by lower-segment caesarean section (793 primary and 542 secondary) at the Calgary General Hospital between January 1985 and April 1988. The overall infection rates were 42·1 and 46·1% for women delivered by primary and secondary caesarean section, respectively. Incisional surgical wound infection accounted for the largest proportion of post-caesarean infections found. Women delivered by primary caesarean section had significantly higher rates of endometritis, deep surgical wound infection and bacteraemia than those delivered by secondary section. All types of post-caesarean infection, except asymptomatic bacteriuria, caused the duration of the post-partum hospital stay to be significantly increased.
