Abstract:
Aim: At our institution, reductions to hydromorphone and fentanyl unit dose quantities provided us with a unique opportunity to study opioid utilization. Materials & methods: A retrospective study examining effects of changes in opioid unit dose on intra-operative and postoperative opioid utilization in patients who underwent laparoscopic cholecystectomy. The study included three arms: the predosage change (n = 254), fentanyl only change group (n = 102) and the postdosage change arm (n = 254). Results: Decreasing opioid unit dosing decreased intraoperative opioid administration and total perioperative utilization. Decreased postanesthesia care unit morphine milligram equivalent (MME) requirements were observed in all, but one group comparison. Conclusion: Our data suggests that opioid unit dosing and administration are directly proportional and that decreased intraoperative MME utilization leads to decreased total perioperative MME use.
