目的研究影响手术切口细菌培养阳性率的相关因素,提高检测的准确性。方法通过回顾性调查方法,对某医院1 000例手术患者切口细菌培养结果进行分析,找出相关因素。结果切口细菌培养的细菌种类及阳性率与病人的皮肤和医生手臂的消毒、手术切口类型、手术时间、手术接台情况等相关因素呈正相关。结论患者手术切口细菌学标本采集和培养应考虑到手术皮肤和术者手消毒及其他因素,采取控制措施,获得准确的培养结果。
Objective To study the factors affecting the positive rate of bacterial culture in surgical incision and improve the accuracy of the detection. Methods By retrospective investigation, the results of incision bacterial culture in 1 000 surgical patients in a hospital were analyzed to find the relevant factors. Results The bacterial species and positive rate of incisional bacterial culture were positively correlated with the factors such as the disinfection of the patient’s skin and doctor’s arm, the type of incision, the operation time and the condition of receiving the operation. Conclusions The collection and culture of bacteriological specimen in patients with surgical incision should take into account the hand disinfection of the skin and the surgeon and other factors, and take control measures to obtain accurate culture results.
