The article describes the experience with percutaneous central venous catheters in 565 neonates with birth weights of 400 to 6810 g. The catheter-related sepsis incidence was 19.1%, or 13.5 infections per 1000 catheter days. By discriminant function analysis, 86% of all neonates studied were correctly classified into the confirmed sepsis and no sepsis groups on the basis of six predictor variables. The model did not accurately predict the neonates who would develop confirmed sepsis. The weight at catheter insertion and length of time for which the catheter was in place were identified as variables that contributed significantly to differentiation between sepsis and no sepsis groups.
本文描述了565例出生体重在400至6810克之间的新生儿使用经皮中心静脉导管的经验。导管相关败血症的发生率为19.1%,即每1000个导管日有13.5例感染。通过判别函数分析,基于六个预测变量,86%的研究新生儿被正确分类到确诊败血症组和无败血症组。该模型未能准确预测会发生确诊败血症的新生儿。导管插入时的体重和导管留置时间被确定为对败血症组和无败血症组之间的区分有显著贡献的变量。
