摘要
目的观察心脏科老年患者外周静脉留置针输液封管活塞夹闭部位对血液回流(简称回血)的影响。方法统一选用BD Intima-Ⅱ型22G密闭式静脉留置针(Y型)留置于前臂进行输液。输液结束后,运用正确统一方法封管,观察留置针回血与不同活塞夹闭部位的关系。根据夹闭的部位将数据分为3组,A组1~3 cm、B组3~6 cm、C组6~9 cm(其中,3 cm归为A组,6 cm归为B组),比较各组回血的发生率。结果 A、B、C组的回血率分别为3.03%、10.42%、14.29%,A组回血发生率明显低于B、C组(P均<0.05)。三组舒适度差异无统计学意义。三组堵管率差异有统计学意义。结论临床上使用外周静脉留置针输液时,封管活塞夹闭位置选1~3 cm(包括3 cm)最佳。
Objective To observe the influence of the sealing position of the peripheral venous indwelling needle on the blood flow in the elderly patients of cardiac section. Methods The BD Intima- Ⅱ type 22G closed intravenous needle （Y type） was Selected to stay in the forearm for infusion. After the infusion, the correct unifi.ed approach was used to seal the pipe. The relationship between the blood return caused by the indwelling needle and different piston clamping positions. The data were divided into three groups according to the clamping part： group A （1-3） era, group B （3-6） era, group C（6-9） cm （3 cm belongs to group A, 6 cm belongs to group B）. The incidence of blood return in each group was compared. Results The blood return rates of group A, B and C were respectively 3.03%, 10.42% and 14.29%. The blood return rate of group A was significantly lower than those of group B and C（P〈0.05）. There was no significant differ- ence in comfort among three groups, while the blocking rates of three groups was statistically significant. Conclusion （1-3） cm （including 3cm） is the best position for sealing piston clamp in the clinical use of peripheral venous indwelling needle infusion.
