脑梗死患者浅静脉留置针封管方法改进的效果

目的通过对脑梗死患者浅静脉留置针封管方法的改进，延长其留置时间，减少静脉炎的发生率。方法40例脑梗死患者按自身对照研究方法分成实验组和对照组，两组分别采用生理盐水加稀释肝素纳封管、单用稀释肝素钠封管，比较两组留置针留置时间、堵管发生率及静脉炎发生率。结果实验组患者留置时间长于对照组、静脉炎发生率小于对照组，差异有统计学意义（P〈0．05）；两组患者堵管发生率差异无统计学意义（P〉0．05）。结论脑梗死患者浅静脉留置针采用生理盐水加稀释肝素钠封管优于稀释肝素钠封管。

Effects of sealing-up method for cerebral infarction patients with the superficial vein catheter

Objective To explore the sealing-up method of the superficial vein catheter for patientswith cerebral infarction in order to extend indwelling time and reduce the incidence of phlebjtis.Methods It was a self-control study.A total of 40 patients with cerebral infarction were divided into two groups:control group and study group.Normal saline combined with diluted heparin were used in the study group while only diluted heparin was used in the control group.The two groups were compared in indwelling time,the incidence of tube-blocked and phlebitis.Results In indwelling time and the incidence of phlebitis,the differences between two groups were significant(P<0.05) while in the incidence of tube-blocked,there was no significant difference (P>0.05).Conclusions For patients with cerebral infarction.using normal saline combined with diluted hepafin to seal shut the superficial vein catheter was superior to only using diluted heparin.
