All hospitals in Norway are required to participate in the Norwegian Surveillance System for Hospital-Acquired Infections (NOIS). Hospitals can choose to have from one to five given surgical procedures under surveillance, caesarean section being one of them. This article describes the incidence of surgical site infections after caesarean sections and identifies causes for such infections.
A national protocol, was developed in accordance with the European protocol (HELICS). Patients undergoing a caesarean section (1 September - 30 November in 2005, 2006 or 2007) in the participating hospitals were included and followed-up for 30 days. Cases were identified in accordance to standardised case definitions. Potential risk factors as well as demographic and clinical data were recorded.
3900 women were included. 290 infections were diagnosed (incidence 8.3 %) among the 3491 women who were followed up after discharge. Only 14 % of the infections were diagnosed during the hospital stay. Age higher than 29 years and contaminated wound class 3 were significantly associated with infection. Among the 54 women with an organ/space or deep infection, 20 were readmitted to the hospital and 11 were reoperated.
One of 12 women who undergo a caesarean section develops a surgical site infection. The incidence of infections in Norway is lower than in many other European countries. We recommend hospitals to evaluate the preventive measures implemented at their institution.
挪威所有医院都必须参与挪威医院获得性感染监测系统（NOIS）。医院可以选择对一至五项特定外科手术进行监测，剖宫产术是其中之一。本文描述了剖宫产术后手术部位感染的发生率，并确定了此类感染的原因。
根据欧洲方案（HELICS）制定了一项国家方案。纳入参与研究的医院中在2005年、2006年或2007年9月1日至11月30日期间接受剖宫产的患者，并进行30天的随访。根据标准化病例定义确定病例。记录潜在风险因素以及人口统计学和临床数据。
纳入3900名女性。在3491名出院后接受随访的女性中，诊断出290例感染（发生率8.3%）。仅14%的感染在住院期间被诊断出。年龄高于29岁和伤口污染程度为3级与感染显著相关。在54例发生器官/腔隙或深部感染的女性中，20例再次入院，11例再次手术。
每12名接受剖宫产的女性中就有1人发生手术部位感染。挪威的感染发生率低于许多其他欧洲国家。我们建议医院评估其机构实施的预防措施。
