普外科切口感染影响因素及病原学分析

目的 分析普外科切口感染影响因素及病原学特点,为临床预防感染及治疗提供参考.方法 选择医院2010年6月-2011年12月普外科手术患者726例的资料,对感染患者的影响因素及病原学进行回顾性分析.结果 结直肠癌根治术感染率最高,为14.29％,其次是阑尾切除手术和肠道修补、切除术,分别为12.44％、10.53％,肝脏手术感染率为3.13％,其他手术未出现感染病例；急期手术、高龄、合并慢性疾病、合并糖尿病、肥胖是导致切口感染的高危因素(P＜0.05)；对感染患者切口分泌物培养结果显示,以革兰阴性杆菌居多,占61.90％,其次是革兰阳性球菌,占38.10％.结论 针对易发切口感染的高危患者加强预防措施,强化污染类手术及急期手术的无菌控制与术后护理,是预防手术切口感染的重要措施.

Impact factors for general surgery incision infections and analysis of etiology

OBJECTIVE To analyze the influencing factors and etiology for general surgery incision infections and provide the reference for clinical prevention and treatment of the infections.METHODS The clinical date of 726 cases of general surgical patients in the hospital from Jun 2010 to Dec 2011 were chosen as the research objects.The influencing factors and etiology for general surgery incision infection were analyzed retrospectively.RESULTS The incidence rate of the infections in the patients undergoing resection of colorectal cancer was the highest(14.29%),followed by the appendectomy(12.44%),intestinal repair and resection(10.53%),and the liver surgery(3.13%),no infections occurred in other cases.The acute surgery,old age,associated with chronic disease,diabetes mellitus,and obesity were the risk factors for incision infection(P <0.05).The incision secretion culture showed that the gram-negative bacilli were the main pathogens,accounting for 61.90%,followed by the gram-positive bacteria(38.10%).CONCLUSION It is of great significance in the prevention of surgical incision infections to strengthen the prevention measures based on the high risk factors and intensify the sterilization control and the postoperative nursing after the contaminate surgery and acute surgery.
