Abstract

Objective: This study aims to assess the impact of postoperative intravenous (IV) acetaminophen on opioid requirements and pain scores in patients following gynecologic procedures. Study Design: A retrospective cohort study of patients undergoing gynecologic procedures was conducted to assess the impact of adding scheduled IV acetaminophen to postoperative analgesic regimens. The control group consisted of patients admitted prior to formulary addition of IV acetaminophen; the study group consisted of patients admitted after formulary addition of IV acetaminophen who received scheduled IV acetaminophen for at least the first 24 hours postoperatively. Opioid requirements 0 to 24 hours postoperatively served as the primary end point. Secondary end points included average pain score, cumulative acetaminophen dose, nonopioid analgesic requirements, and rate of adverse events 0 to 24 hours postoperatively. Results: One hundred and thirty-seven patients who underwent a gynecologic procedure from January 2009 to April 2013 were included in this study. Baseline characteristics were similar between the groups. In the first 24 hours postoperatively, there was no difference in opioid requirements between the groups (21 mg [interquartile range, IQR, 15-39.8 mg] vs 32.6 mg [IQR, 16.75-41 mg], P = 0.150). The average pain score and incidence of adverse events did not differ between the 2 groups. Conclusion: Postoperative administration of IV acetaminophen did not provide a significant opioid-sparing effect in patients undergoing gynecologic procedures.
