Objective To investigate the effect of refining dressing change process to prevent peripheral venipuncture central venous catheter (PICC) catheter-related infection.Methods 114 cases of PICC patients were randomly divided into control group(56cases) and observation group(58 cases).Control group used the general dressing set and followed the routine dressing change process,while observation group used improved dressing set and refined the dressing change process.Observed catheter-related local infection and syrnptoms of patients in two groups.Results The catheter local infection incidence,average catheter time,and catheter pathogenic detection positive rate of two groups had statistically significant difference(P＜ 0.05),the rate of catheter-related blood stream infection (CRBSI) had no significant difference(P ＞ 0.05).Conclusion Refining dressing change process,strengthening the maintenance and management of the PICC,can effectively prevent and control of the PICC catheter-related infections.%目的 探讨细化换药流程预防经外周静脉穿刺中心静脉置管(PICC)导管相关感染的效果.方法 对114例PICC置管患者随机分为对照组(56例)和观察组(58例),对照组使用普通换药包遵循常规换药流程,观察组改良换药包及细化换药流程,观察两组患者导管相关局部感染及全身症状.结果 两组导管局部感染发生率比较差异有统计学意义(P＜0.05),但导管相关血流感染(CRBSI)无明显区别(P＞0.05);两组导管平均置管天数比较差异有显著性(P ＜0.05);两组导管病原学送检阳性率比较差异有统计学意义(P＜0.05),导管尖端检出细菌以表皮葡萄球菌为主.结论 采用细化换药流程,加强PICC导管的维护管理,能有效预防和控制PICC导管相关感染.
