Although the World Health Organization recommends not using sterile technique for low-risk delivery and literature doesn't report a significant association between clean delivery and higher risk for infection, sterile technique remains a prevalent practice. We conducted our study in the obstetric clinics of two hospitals of Piemonte Region (Italy) that use different operative care models ('clean' vs. 'sterile').
Aim of the study was to describe practices and procedures used by midwives during delivery, according to the model adopted, and to compare the incidence of perineal infection between use of 'clean' versus 'sterile' practices for intrapartum care.
Prospective cohort study. 200 women for each hospital were included in the study. Health care behaviour and practices performed during the different stages of delivery were observed and recorded on an observation sheet. Follow-up was conducted for 1 month after discharge in order to detect infections of reproductive organs.
Many differences were described in procedures and health care worker practices between the two hospitals and even among operators of the same ward, but a greater compliance with the theoretical model adopted was described among midwives and physicians of the 'clean' delivery model. No infections were detected in either of the two samples of women included in the study.
From our observations we can conclude that many reasons support the adoption of 'clean' technique for low-risk deliveries: reducing inappropriate use of resources and costs for health care, less medicalization, less frequent use of episiotomy and shaving, major compliance of operators with simple and coherent practices and procedures.
世界卫生组织建议低危分娩不采用无菌技术,且文献并未报道清洁分娩与更高感染风险之间存在显著关联,但无菌技术仍然是一种普遍的做法。我们在意大利皮埃蒙特地区(Piemonte Region)的两家医院的产科诊所进行了这项研究,这两家医院采用了不同的手术护理模式(“清洁”vs.“无菌”)。
本研究旨在根据所采用的模式描述助产士在分娩过程中的实践和程序,并比较在分娩期间采用“清洁”与“无菌”实践时会阴感染的发生率。
前瞻性队列研究。每家医院纳入 200 名妇女。观察并记录在不同分娩阶段进行的保健行为和实践,然后在出院后 1 个月进行随访,以检测生殖器官感染。
两家医院之间,甚至同一病房的医护人员之间,在程序和医护人员实践方面存在许多差异,但“清洁”分娩模式的助产士和医生对理论模型的遵循度更高。在研究纳入的两组妇女中,均未发现感染。
从我们的观察中可以得出结论,许多原因支持采用“清洁”技术进行低危分娩:减少对卫生保健资源和成本的不当使用,减少医学化,减少会阴切开术和剃毛的频繁使用,操作人员对简单一致的实践和程序的高度遵守。
