ABSTRACT

Objective To investigate the pressing time and puncture site bleeding after extubation of superficial venous catheter in elderly patients.Methods Four hundred elderly inpatients were selected from respiratory department during June 2015 and December 2015 and were divided into two groups200 patients as experimental group with pressing time of 5-6 minutes and 200 patients as control group with pressing time of 3-4 minutes.The same group of nurses pressed the puncture site after extubation and changes on skin and vessels were observed,which was to find out the optimal pressing time after extubation of superficial venous catheter in elderly patients.Results The presence of bleeding,bruising,success rate of the second puncture,swelling,pain and degree of comfort were compared between two groups and significant differences were found (P＜0.05).Conclusion Compared with those in control group,less bleeding,bruising,swelling,and pain,higher success rate of the second puncture and lower degree of comfort were found in experimental group.
