摘　　要：目的对脊柱后路内固定手术过程中不同时段外科手套细菌污染状况进行调查,为医院感染的预防提供参考依据。方法选取2020年11月至2021年4月某三甲医院脊柱后路内固定手术中符合纳入标准的150只外科手套,分别在使用0、1、2、3、4 h时采样,进行细菌培养并对培养结果进行分析。结果150只外科手套中有16只细菌培养结果为阳性,阳性率为10.67%;外科手套在使用2、3、4 h时细菌培养阳性率分别为0.67%、2.67%、7.33%,不同时段外科手污染状况比较差异有统计学意义(P<0.01)。结论脊柱后路内固定手术中外科手套随着使用时间延长细菌污染率增加,应针对相关因素进行干预,以减少术中外科手套污染率,从而降低医院感染风险。Objective To investigate the bacterial contamination of surgical gloves in different periods of spinal posterior internal fixation,and to provide reference for the prevention of nosocomial infection.Methods 150 surgical gloves that met the inclusion criteria in posterior spinal internal fixation surgery in a tertiary first-class hospital were selected from November 2020 to April 2021.Samples were taken at 0,1,2,3 and 4 hours after use,respectively,and the culture results were analyzed.Results 16 of the 150 surgical gloves were positive for bacterial culture,and the positive rate was 10.67%;the positive rates of bacterial culture for surgical gloves were 0.67%,2.67%,and 7.33%at 2,3,and 4 hours,respectively.The differences in pollution status were statistically significant(P<0.01).Conclusions The bacterial contamination rate of surgical gloves increases with the use time of posterior spinal fixation,and intervention should be carried out to reduce the contamination rate of surgical gloves and reduce the risk of nosocomial infection.
