چکیده

purpose: patients may control postoperative pain by self-administration of intravenous opioids   using devices designed for this purpose (patient controlled analgesia or pca). this study set out   to determine whether any of the two opioid administrations (i.e. pca or conventional analgesia)   would provide superior pain relief among patients undergoing laparoscopic cholecystectomy   or not.   materials and methods: in a clinical trial the pca group received self-administered intermittent   intravenous morphine via pca and the conventional group received intravenous pethidine   every 6 hours per day. the patients were assessed on an hourly basis for the first 4 hours after   surgery, every 2 hours for the next 8 hours and every 4 hours for next 12 hours. two methods   were used in order to evaluate the degree of pain relief in patients: (1) facial pain scale pain   assessment based on the patient’s appearance and (2) numerical rating scale based on patient   ratings of their pain.   results: forty eight patients (79.1% female, 20.1% male) with a mean age of 45.7 ± 10.7 years   old were enrolled into the study. during the first 24 hours after laparoscopic cholecystectomy,   pain intensity based on facial pain scale was lower in the pca group. however, the difference   was significant only in the second hour (mean pain score in pca group: 2.9, mean pain score   in conventional group: 3.7, p = .007). also, the mean pain scores based on numerical rating   scale were significantly lower in pca group except for the first hour. although it was not   significantly lower than conventional group (mean pain score in pca group: 4.2, mean pain   score in conventional group: 4.6, p = .45).   conclusion: intravenous pca resulted in better postoperative pain reduction compared to   intermittent bolus opioid delivery in laparoscopic cholecystectomy.

More recently, we have implemented a protocol (TLC) that utilizes a multimodal approach. The purpose of this study was to determine whether this change has improved pain control and decreased narcotic utilization. ...
