烧伤后整形手术区感染的危险因素分析

AN ANALYSIS OF RISK FACTORS OF INFECTION AFTER RECONSTRUCTIVE OPERATIONS FOR POSTBURN CONTRACTURES

回顾了１９８８～１９９８年１５９０例烧伤后的整形手术，其中５４例发生术区感染，感染率为３．４％。在统计的５项危险因素中，其中手术时间超过４ｈ。手术前住院日超过１０天和术区有残留创面和（或）术区瘢痕凸凹不平，这３项因素均可明显增加术后感染的发生率。术前过早备皮是导致术区感染的可能因素。预防性应用抗生素与术后术区感染的发生率似乎无密切关系。

One thousand five hundred and ninety patients undergone reconstructive operations for postburn contractures during the eleven year period between 1988 and 1998 were reviewed retrospectively. Fifty four patients developed infection in the operative fields, and the infection incidence was 3.4%. Five potential risk factors in relation to infection were analyzed. Among them three factors associated strongly with the infection of postburn wounds, i.e:(1) duration of surgery lasting over 4 hours; (2) preoperative hospital stay longer than 10 days; and (3)patients with residual wound in operative fields. Shaving of the operative field too early before operation appeared to be associated with increased opportunity of infection, although statistical significance was not demonstrated. There were no statistically significant differences between the use of prophylactic antibiotics and infections in the operative fields.
