We performed this study to determine if percutaneous central lines (PCLs) were associated with infection more often than peripherally placed intravenous catheters (PIVs).
We conducted a retrospective, cohort study of 53 infants with PCLs inserted from March 1993 to February 1995 for evidence of catheter-related bloodstream infection and 97 cohorts with PIVs who were matched to the infants with PCLs by admission date and birth weight. We considered an infant to have catheter-related bloodstream infection if bacteremia occurred while the PCL or PIV was in place with no other identifiable infection focus. Statistical analyses were performed by using either Student's t test or the Mann-Whitney U test where appropriate.
There were eight infections per 1000 catheter days of PCL use and nine infections per 1000 catheter days of PIV use.
PCLs do not become infected more often than PIVs.
我们开展此项研究以确定经皮中心静脉导管（PCL）引发感染的频率是否高于外周静脉导管（PIV）。
我们进行了一项回顾性队列研究，研究对象为1993年3月至1995年2月期间插入PCL的53例婴儿，以寻找导管相关血流感染的证据，以及97例与插入PCL的婴儿按入院日期和出生体重匹配的PIV队列。如果在PCL或PIV在位时发生菌血症且无其他可识别的感染源，我们则认为该婴儿患有导管相关血流感染。在适当情况下，使用学生t检验或曼-惠特尼U检验进行统计分析。
PCL每1000导管日有8例感染，PIV每1000导管日有9例感染。
PCL引发感染的频率并不高于PIV。
