摘　　要：目的通过对密闭式留置针两种不同置管方法比较,以探讨更适合危重症患者导管留置的方法。方法将80例需长期进行静脉输液的危重症患者随机分为对照组和观察组各40例。对照组采用常规方法,观察组采用改进的方法(即退针芯送软管,再退针芯送软管,依次将软管送入血管中的方法),比较两组一次置管的成功率。结果在血管粗、直、走向较长的情况下,对照组和观察组一次置管成功率分别为96.66%和100%,两组比较有统计学意义(P<0.05);在血管较细、弯曲、走向较短的情况下,对照组和观察组一次置管成功率分别为70%和95.24%,两组比较有统计学意义(P<0.001)。结论改进法可提高危重症患者的一次置管成功率,尤其在血管细、弯曲、走向较短情况下效果更明显。Objective To explore a more suitable close venous indwelling methods for critically ill patients. Methods Eighty critically ill patients undergoing long-term intravenous infusion were randomly divided into control group and observation group （n=40 in each group）. The observation group was treated by conventional method, while the control group was treated by the improved method. The success rate at one attempt was compared between the two groups. Results On long, and wide straight blood vessels, the success rate in the control and observation groups was 96.66% and 100% respectively, with the difference being significant between two groups （P〈0.05）. On short, and narrow curved blood vessels, the success rate in the control and observation groups was 70% and 95.24% respectively, with the difference being obviously significant （P〈0.001）. Conclusion The improved method can increase the success rate of close venous indwelling needles in the critically ill patients.
