不同规格型号静脉留置针在老年肺心病患者中的应用效果观察

目的探讨两种不同规格型号静脉留置针在老年肺心病患者中的应用效果。方法 60例老年肺心将病患者随机分成两组,BD-22G静脉留置针组（对照组）30例,BD-24G静脉留置针组（观察组）30例。比较两组留置针在穿刺成功率、静脉炎和堵管率的发生及留置时间等方面的情况。结果两组一次性穿刺成功率及静脉炎发生率有明显差异,观察组明显低于对照组（P〈0.05）,在穿刺时及留置期间观察组患者的疼痛感也明显低于对照组的患者（P〈0.05）,堵管率无明显差异（P〉0.05）。结论 24G留置针比22G安留置针更适合运用于老年肺心病患者。

Clinical observation of different types of venous indwelling needle on aged cor pulmonary patients

Objective To examine the clinical efficacy of two types of venous indwelling needle on aged cor pulmonary patients.Methods 60 aged cor pulmonary patients were randomly divided into two groups,thirty patients in control group with BD-22G venous indwelling needle and the rest were in observation group with BD-24G venous indwelling needle,the success rate of venipuncture,phlebitis,catheter blocking and indwelling time were compared between two groups.Results In observation group,twenty nine patients were successful at once venipuncture(96.67%),one patient got phlebitis(3.33%),while in control group there were only nineteen patients were successful at once venipuncture(63.33%),four patients got phlebitis(13.33%),the pain in observation group patients was significantly lower than control group(P<0.05),there was no differences between two groups on catheter blocking rates(P>0.05).Conclusion BD-24G venous indwelling needle is more suitable for aged cor pulmonary patients than BD-22G venous indwelling needle.
