PURPOSE
To compare the effects of heparin versus normal saline flush solutions on the duration of patency of peripheral IV catheters in neonates.
METHODS
A quasi experimental design compared the outcomes in 87 infants who were 32 weeks or greater gestation at birth. Thirty-three received heparin and 54 received normal saline.
RESULTS
There were 159 starts among the subjects. No statistically significant difference in duration of patency between the groups was found. The duration was significantly longer for term than preterm infants and for insertion in scalp, arm, or hand than for leg or foot.
CONCLUSIONS
Gestational age and site of insertion were the only predictor variables related to duration of patency for IV catheters.
目的
比较肝素与生理盐水冲洗液对新生儿外周静脉留置针通畅持续时间的影响。
方法
采用准实验设计，比较了87例出生时孕周为32周或更大的婴儿的结果。33例接受肝素治疗，54例接受生理盐水治疗。
结果
受试者共进行了159次置管。两组之间的通畅持续时间没有统计学上的显著差异。足月儿的通畅持续时间明显长于早产儿，头皮、手臂或手部置管的通畅持续时间明显长于腿部或足部置管。
结论
胎龄和置管部位是与静脉留置针通畅持续时间相关的唯一预测变量。
