The increased use of epidural analgesia with catheter leads to the need to demonstrate the safety of this method and know the incidence of catheter colonization, inserted postoperatively for epidural analgesia, and the bacteria responsible for this colonization.
From November 2011 to April 2012, patients electively operated and maintained under epidural catheter for postoperative analgesia were evaluated. The catheter tip was collected for semiquantitative and qualitative microbiological analysis.
Of 68 cultured catheters, six tips (8.8%) had positive cultures. No patient had superficial or deep infection. The mean duration of catheter use was 43.45 h (18-118) (p=0.0894). The type of surgery (contaminated or uncontaminated), physical status of patients, and surgical time showed no relation with the colonization of catheters. Microorganisms isolated from the catheter tip were Staphylococcus aureus, Pseudomonas aeruginosa and Sphingomonas paucimobilis.
Postoperative epidural catheter analgesia, under these study conditions, was found to be low risk for bacterial colonization in patients at surgical wards.
硬膜外导管镇痛的使用增加，这就需要证明该方法的安全性，并了解术后用于硬膜外镇痛的导管定植发生率以及导致这种定植的细菌。
对2011年11月至2012年4月期间接受择期手术并通过硬膜外导管进行术后镇痛的患者进行评估。收集导管尖端进行半定量和定性微生物分析。
在68根培养的导管中，6个尖端（8.8%）培养结果呈阳性。没有患者发生浅表或深部感染。导管使用的平均时长为43.45小时（18 - 118小时）（p = 0.0894）。手术类型（污染或未污染）、患者身体状况和手术时间与导管定植无关。从导管尖端分离出的微生物有金黄色葡萄球菌、铜绿假单胞菌和少动鞘氨醇单胞菌。
在这些研究条件下，发现术后硬膜外导管镇痛在外科病房患者中细菌定植风险较低。
