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.     

产后并发症341例分析

报告本院1981年1月至1985年12月,住院分娩4588例中产后并发症341例,发病率为7.43％。其中,产后出血1189例,占4.12％;分娩损伤71例,占1.55％;其它产后病81例,占1.76％。妊娠41—42周并发症发生率为11.14％;超过42周高达15.56％。分娩方式以剖腹产术后并发症最多,占12.48％,提示应对手术中无菌操作与环境,以及分娩后处理应予以足够重视。     

Risk factors for Caesarean section in Italy: results of amulticentre study

A recent large increase in Caesarean section (CS) in Italy was the initial stimulus for a study to identify risk factors for CS and, if possible, to suggest strategies to counteract the rise. The study was conducted in three hospitals where a wide range of individual variables was collected from the clinical records and from personal interviews. Crude CS rates and odds ratios were evaluated for each single variable while logistic regression has been used to investigate possible confounding factors. The study involved 1316 consecutive deliveries. Crude CS rates were 29.4%, 15.7% and 16.1%. Variables identified as high risk factors were pre-eclampsia, previous CS, breech and other non-vertex presentations. Antenatal care under an obstetrician working in the same hospital, a low number of antenatal consultations, previous miscarriages, offer (by obstetrician) and request (by women) for CS showed significantly high odds ratios (ORs). Previous live births was strongly negatively associated with CS. No relationship between type of delivery and social status was observed while a physician factor was detected in all three hospitals where rates for different physicians ranged from 0% to 52.8%. Apart from the main medical indications for Caesarean section (previous CS, breech presentation), the results seem to indicate that individual practice style may be an important determinant of the wide variation in the rates of Caesarean delivery. While this may have been suspected before this study, these results are the first hard data to indicate that, in Italy, CS is widely performed for non-medical reasons.

含服米索前列醇预防选择性剖宫产产后出血

目的：探讨舌下含服米索前列醇预防剖宫产产后出血的效果。方法：将妊娠晚期单胎选择性剖宫产者200例随机分为两组,研究组110例，在第二产程末胎头娩出后舌下含服米索400μg，对照组90例，在胎儿娩出后静脉注射催产素20IU，观察产后2h出血量和用米索前后血压及用药后出现的副作用，结果：产后2h内的出血量，研究组与对照组分别为174．43ml和219.73ml，二组比较有显著性差异（P＜0．01），用米索前后血压比较，二组无显著性差异（P＞0．05），结论：舌下含服前列醇促进子宫收缩作用强于催产素，能减少产后出血，也适用于某些与血管变化有关的高危孕产妇，预防产后出血。     

Air Embolism Death of a Pregnant Woman Secondary to Orogenital Sex

Air embolism produced by vaginal insufflation is an unusual but potentially lethal consequence of sexual activity, especially in the pregnant patient. Reported here is the case of a young pregnant woman who presented to the ED in full cardiac arrest, with little history to explain her condition. Despite aggressive resuscitative measures, the patient died, but her infant son was delivered via perimortem cesarean section and survived. A high level of suspicion for air embolism should be maintained for young women who unexpectedly develop cardiac arrest, particularly during sexual activity. Air embolism patients may require vigorous medical resuscitation, hyperbaric oxygen therapy, or surgical intervention to survive. The emergency physician should be familiar with the indications for perimortem cesarean delivery in the third-trimester patient presenting to the ED with cardiac arrest.

Experiences and perceived roles of occupational therapists working with children with special learning needs during transition to school: A pilot study

Occupational therapists provide support to children with special learning needs and their families during the child's transition from early childhood to mainstream school. Little has been documented regarding the role and experiences of occupational therapists working with children, families and teachers during transition in an Australian context. Six paediatric occupational therapists from one geographical area in New South Wales were interviewed and asked to relay their role and experiences when providing a service to children with special learning needs during their transition to school. Participants described their role to include: preparing the child for school; working with school personnel; and providing parental support. Although participants described both positive and negative experiences, among the negative experiences were: limited time to provide a service; recommendations to school personnel not being followed; school personnel not being supportive; feeling uncomfortable in the classroom; and limited involvement in planning. Participants described a role which is consistent with current school-based occupational therapy practice; however, in the participants' experience, there was a gap between the ideal service and what participants were able to provide. This included limited collaboration with teachers.     

第2产程剖宫产术对母婴的影响

本文对我院近 4年来第 2产程 (以下简称 2程 )剖宫产 6 1例进行回顾性分析。资料表明 :第 2产程剖宫产术易合并羊水污染及术时并发症 ,新生儿Apgar氏评分低 ,术后并发症高于对照组 (P <0 .0 5 ) ,提示第 2产程剖宫产术比一般头位急症剖宫产术对母婴不利 ,其并发症的发生与第 2产程的延长相关 (P <0 .0 1) ,故应把握时机尽量减少宫口开全后施行剖宫产。
