objective:to investigate the present situation and features of infection of incisional wound after sesarean section,so as to find the best method in the diagnosis and prevention of incisional infection.methods:the patients undergoing cesarean section were investigated retrospectively for studying the basic features of incisional infection after operation.results:of 13798 investigated parturients after cesarean section,96 were found with the infection of incisional wound accounting for 0.7%.the main symptom was distending pain or jumping pain on the site of incision,the emergence time of symptom in major cases(78.13%) was 4 to 7 days after operation.the local therapy including drainage,ultraviolet rays or infrared rays irradiation and ultrashort wave therapy was the main method in concert with antibiotic treatment and support therapy.the antibiotic therapy was changeable,and albumin intromission was the main method in the general support therapy.

目的：了解剖宫产手术切口感染的现状特点，分析其感染原因，便于临床上更好的诊断和预防切口感染。方法：采用回顾性调查方法，研究剖宫产切口感染的基本特征。结果：调查产妇13 798例，其中切口感染96例，感染率0.7％，症状主要表现为切口胀痛、跳痛，78.13％出现在术后4～7天，57例产妇伴有发热，占59.38％；感染后治疗主要是局部治疗配合抗生素治疗、支持治疗，局部治疗以引流、紫外线或红外线照射、超短波疗法为主，抗生素的使用比较混乱，全身支持治疗以输入白蛋白为主。

It was found that the practical value of the relative intensity of ultraviolet radiation in the radiation distance of 50 to 100 cm was conincident with theoretical one calculated by the square inverse ratio law.

结果：照射距离为50～100cm时紫外线照射相对强度的实测值与以平方反比定律计算的理论值相符，25cm时实测值远小于理论值。
