心胸外科手术中心静脉导管感染的相关因素分析

Analysis of related factors of central venous catheter infection in cardiothoracic surgery

目的:分析心胸外科中心静脉导管感染相关危险因素。方法:选取240例留置中心静脉导管心脏手术患者,对中心静脉导管感染情况进行统计,分析相关危险因素,进而制定针对性的解决对策。结果:240例心脏手术患者中,中心静脉导管感染率为8.33%(20/240),且感染率随中心静脉导管留置时间延长而明显升高(P<0.05);颈内静脉导管感染率为10.71%(15/140),明显高于锁骨下静脉的5.00%(5/100)(P<0.05);三腔导管感染率为15.56%(14/90),明显高于双腔导管的4.00%(6/150)(P<0.05)。结论:置管时间、置管部位与导管种类均是心胸外科中心静脉导管感染的危险因素,临床上应积极寻找针对性措施以降低感染发生率,确保患者生命安全。

Objective： To analyze risk factors associated with central venous catheter infection in cardiothoracic surgery. Methods： 240 patients with indwelling central venous catheters undergoing cardiopulmonary surgery were selected as the study subjects. The status of central venous catheter infection was analyzed,and the related risk factors were analyzed to develop the targeted solutions. Results： In 240 patients undergoing cardiac surgery,the central venous catheter infection rate was 8.33%（20/240）,and the infection rate increased with the extension of the central venous catheter indwelling time（P〈0.05）. The rate of internal jugular vein catheter infection was 10.71%（15/140）,significantly higher than 5.00%（5/100） of the subclavian vein（P〈0.05）. The three-lumen catheter infection rate was 15.56%（14/90）,significantly higher than the 4.00 of the double lumen catheter 4.00%（6/150）（P〈0.05）. Conclusions： The risk factors of central venous catheter infection in cardiothoracic surgery include the catheterization time,the location of the catheter,and the type of catheter. Clinically,it should actively seek targeted measures to reduce the incidence of infection and ensure the safety of the patients.
