超声导引结合改良塞丁格技术行上臂PICC置入与盲穿置管的比较

目的 比较超声导引结合改良塞丁格技术进行上臂PICC置入与传统PICC置入的效果差异.方法 采用多中心随机对照研究,共5家三级甲等肿瘤专科医院的150例患者参与本次研究,按照随机数字表法分为观察组和对照组,各75例.分别在置管过程中、置管第2天、中间回访和置管第7天,比较两组患者置管成功率、穿刺点渗血、机械性静脉炎发生情况及置管手臂舒适度等指标的差别.结果 两组患者置管成功率均为100%,出血量、导管末端位置的差异无统计学意义(P＞0.05);置管第2天及中间回访时,两组患者穿刺点渗血、穿刺点情况、手指肿胀的差异亦无统计学意义(P＞0.05),但观察组机械性静脉炎发生情况好于对照组,差异有统计学意义(P＜0.05);第7天回访时,观察组穿刺点渗血、手指肿胀、机械性静脉炎发生情况、置管手臂的舒适度均优于对照组,差异有统计学意义(P＜0.05或P＜0.01).结论 超声导引结合改良塞丁格技术进行上臂PICC置入能明显改善穿刺点渗血、手指肿胀、机械性静脉炎和置管手臂舒适度.

Comparison of efficacies of upper arm placement of peripherally inserted central venous catheters:using ultrasound guidance and modified Seldinger technique versus traditional method

Objective To compare the efficacies of upper arm placement of peripherally inserted central venous catheters using ultrasound guidance and modified Seldinger technique with traditional method.Methods A multicenter,randomized,and blind controlled trial was conducted in 150 patients from five cancer hospitals.The patients were randomly assigned to control group and experiment group.The success rate of PICC placement,the complications of insertion sites,mechanical phlebitis,and the comfort of insertion arms we...
