Abstract:
Objective To explore a venipuncture method that can reduce the pain, improve the suc-cess rate of puncture as well as reduce vascular injury. Methods Self-controlled method was applied in 200 patients, needle tips with 20～25°,31～40°,41～50°, 51～60°, > 60° angles on the top of the blood ves-sels,the inclined plane of the needle parallel to the longitudinal axis of the blood vessel (that was,the in-clined plane to the left or right) or traditional method with upward of needle tips were adopted, the observa-tion group and the control group were divided according to different methods, pain and success rate of puncture were compared. Results There were differences between the two groups,results of the observa-tion group were better than those of the control group (except when > 60°, success rate showed no differ-ence). Conclusions Venipuncture with needle tip parallel to the longitudinal axis of the blood vessels can significantly reduce pain in patients, improve the success rate of puncture and reduce the vascular in-jury, which were superior to the traditional venipuncture method. Whatever method is chosen, 51～60° is the best angie into the vessel.
