静脉输液穿刺速度和静脉穿刺难度相关性分析

目的探讨静脉输液穿刺速度和静脉穿刺难度的相关性。方法用秒表测量437例次静脉输液进针时间并记录,评价静脉穿刺难度:静脉细小、管壁硬化、肥胖、水肿、婴幼儿、老年等,应用Pearson积矩法的相关系数对静脉输液穿刺速度与静脉穿刺难度进行相关性分析。结果通过单因素分析发现进针时间与静脉穿刺难度呈正相关性(P<0.01或P<0.05)。结论对静脉输液穿刺难度高的静脉细小、静脉管壁薄、脆性静脉、婴幼儿、老年患者应相应放慢进针速度;准确增加进针时间能有效提高静脉输液穿刺成功率。

Study of the relationship between venipuncture velocity and venipuncture difficulty

Objective To study the relationship between venipuncture velocity and venipuncture difficulty.Methods The needing times of 437 times intravenous transfusion were measured by stopwatch and were written down.The grade of venipuncture difficulty was evaluated according to vein slight,vascular sclerosis,obesity,edema,infant,elder,and etc.The coefficient correlation of venipuncture velocity and venipuncture difficulty was analyzed by Pearson square method.Results By single factor analysis,there was a significant positive correlation between venipuncture velocity and venipuncture difficulty(P<0.01 or P<0.05).Conclusions For the patient who has veinlet,brittle vein or thin vein,or is an infant or older,venipuncture speed should be slow.In order to improve the successful ratio during intravenous transfusion,needling time should be increased accurately.
