安全型留置针的不同送管方法对穿刺成功率的影响

Effect of two different catheter insertion ways using BD Saf-T-Intima closed IV catheter on puncture achievement ratio

目的探讨不同送管方法对急性白血病化疗患者穿刺安全型留置针成功率的影响。方法采用前瞻I生研究方法，将化疗患者使用BD安全型留置针输液160例次随机分为A组、B组各80例，分别采用不同送管方法，A组为传统的见回血后退出针芯约0．5cm，连针带管一同送入血管内，再完全撤出针芯；B组为见回血后再进针0．1～0．2cm，完全撤出针芯，将外套管送入血管。结果两组成功率分别为77．5％和92．5％。B组穿刺成功率明显高于A组，差异有统计学意义（P〈0．01）。结论针对长期化疗的急性白血病患者的外周血管特点，见回血后再进针0．1—0．2cm，完全撤出针芯，将外套管送入血管的送管方法可以提高穿刺安全型留置针的成功率。

Objective To explore the effect of two different catheter insertion ways using BD Saf-T- Intima closed IV catheter on puncture achievement ratio. Methods 160 times punctured by BD Saf-T-Intima closed IV catheter were randomly divided into 2 groups （ 80 cases respectively for A and B ） for prospective studies. Each group was received different catheter insertion ways respectively. Group A received traditional way ： the stylet was removed O. 5cm when blood flowing back into the catheter. After the styler/catheter unit were advanced into the vein completely, the stylet was removed from the catheter. For group B, the stylet/catheter unit was advanced into the vein O. 1 - O. 2 cm further when blood flowing back into the catheter. After the stylet was removed completely, the plastic catheter was advanced into the vein. Results Achievement ratios for each group were 77.5% and 92.5%, success rate of group B is obviously higher than group A （ P 〈 0. 01 ）. Conclusions Adopting the catheter insertion method in group B can improve the puncture achievement ratio in acute leukemia patients with chemotherapy.
