Exploration of duration of intravenous analgesia pump after gynecological surgery

Abstract

Objective To evaluate the influence of the duration of patient-controlled intravenous analgesia (PCIA)on pain and gastrointestinal function after gynecological abdominal surgery.Methods Patients who received gynecological abdominal surgery were divided into 3 groups according to using time of PCIA for 24 hours,48 hours,72 hours.There were 30 cases in each group.Pain intensity,gastrointestinal peristalsis time,anal exhaust time,getting out-of-bed time,voluntary micturition time,nausea and vomiting were compared among three groups after stopping PCIA.Results There were no significant differences in VAS score among three groups at each time point.There were no significant differences in voluntary micturition time among three groups.The anal exhaust time,getting out-of-bed time in 24-hour group were earlier than those of the other two groups,the differences were significant; The nausea and vomiting in 24-hour group were lower than the other two groups,the difference was significant.Conclusions The application of PCIA can effectively relieve acute pain 24 hours after surgery,but the effect was not obvious on pain induced by activities after 24 hours.But the side effects induced by analgesia pump(anesthetic)still work,such as vomiting,long duration of discharge,activity inconvenience.So PCIA should be stopped at right time in order to reduce complications and facilitate for recovery of patients after the surgery.
