摘要
目的了解心血管术后危重患者长期留置中心静脉导管的相关感染情况。方法回顾分析166例心血管术后危重患者长期留置中心静脉导管的尖端和皮下段细菌培养的临床资料。结果中心静脉导管的尖端病原菌阳性率为41.0%,皮下段病原菌阳性率为47.0%;置管时间>18 d,体温>38.5℃,股静脉置管是导管相关感染的主要危险因素(P<0.05)。结论心血管术后危重患者长期留置中心静脉导管的感染率较高,必须引起足够的重视,并采取有效的干预措施。
OBJECTIVE To investigate the patterns of catheter related infection in critically ill patients after cardiac surgery with prolonged central venous catheters. METHODS The materials of culture of catheter tip and subcutaneous segments in 166 critically ill patients after cardiac surgery with prolonged central venous catheters were reviewed. RESULTS The positive pathogenic bacteria ratio of catheter tip segments was 41. 0% and the positive ratio of catheter subcutaneous segments was 47. 0%. Catheterization longer than 18 days, body temperature higher than 38.5℃ and insertion sites of femoral veins were the variables associated with significantly increased risk of catheter related infection. CONCLUSIONS The positive pathogenic bacteria ratio of central venous catheters in critically ill patients after cardiac surgery with prolonged central venous catheters is high, more attention must be paid to catheter related infection, and efficacious interventions must be laid down.
