摘要
目的提高静脉留置针穿刺困难者的一次穿刺成功率。方法将200例需行静脉留置针穿刺的患者随机分为对照组和观察组,各100例。对照组按常规穿刺,观察组采用负压技术穿刺,即将容量为2ml的吸球和三通接头接上留置针,使之穿刺时形成负压,再行穿刺。结果两组静脉穿刺回血率、一次成功率比较,差异有显著性意义(χ2=18.32、27.56,均P<0.01);留置针保留时间比较,差异无显著性意义(P>0.05);两组颈外静脉、大隐静脉穿刺回血率、一次穿刺成功率比较,差异有显著性意义(χ2=18.26、18.26、5.00、5.00,P<0.01或P<0.05);两组股静脉一次穿刺成功率比较,差异有显著性意义(P<0.01)。结论负压技术可提高留置针穿刺回血率和一次穿刺成功率。
Objective To explore the measures for improving the success rate of indwelling needle. Methods Two hundred patients to receive indwelling needle puncturing were divided into a control group and an observation group at random, with 100 subjects in each group. Routine puncture was used in the control group and negative pressure puncture in the observation group. With negative pressure puncture, a 2 ml balloon was connected to a three-way catheter to create negative pressure during puncture. Results There were significant difference in blood-regurgitation rate and success rate at the first attempt between two groups （X^2 = 18.32,27.56, P〈0.01 for both）. There were significant differences in blood-regurgitation rates during the puncture of external jugular and great saphenous veins and in success rate at the first attempt in the puncture of external jugular, femoral and great saphenous vein between the two groups （X^2= 18.26,18.26,5.00,5.00, P〈0.01 or P〈0.05 ）. Conclusion The negative pressure technique can improve the blood regurgitation rate and success rate at the first attempt in the puncture with indwelling needle.
