Abstract：Objective To investigate the effect of using a subcutaneous vein finder in prehospital first aid at night.Methods From February 2017 to June 2018,200 pre-hospital emergency patients from the Cangzhou Medical Emergency Center were selected as the study subjects.They were divided into the control group and the experimental group by closed envelope method,and 100 patients in each group.During the rescue process,the venous puncture was performed at night using conventional general illumination.The experimental group was treated with a vein finder to perform venipuncture at night,and the number of successful punctures,second punctures,three or more punctures in the two groups and the success rate was evaluated for clinical efficacy and safety.Results The success rate of one puncture in the experimental group was higher than that in the control group (P<0.05）.The probability of complications such as solid catheter occlusion,fluid leakage,phlebitis,and infusion of hypertonic fluid pain in the experimental group was 4.0%.Compared with the control group,it was lower than 13.0%,the differences were statistically significant(P<0.05）.Conclusion In the pre-hospital emergency treatment process at night,the subcutaneous vein finder can effectively improve the success rate of the nursing staff to establish venous access for the patient,which is reliable,simple and safe.Clinically easy to promote treatment,recommended promotion.
