Background: Postoperative opioid-induced respiratory depression and oversedation can lead to fatal events and increase perioperative mortality. In reports from major academic centers, naloxone administration has been used as a proxy for severe opioid overdose. Herein, we studied the incidence, clinical characteristics, and outcomes of postoperative naloxone use in a mid-size community hospital.
Methods: This was a retrospective review of adult patients who received naloxone within 48 postoperative hours between July 9, 2017, and May 31, 2022.
Results: During the study timeframe, a total of 23,362 surgical procedures were performed and a total of 19 patients received naloxone (8 in the recovery room, 11 on hospital wards), with an incidence of 8.1 [95% confidence interval 4.9-12.7] per 10,000 anesthetics. In 12 cases (63%), naloxone was indicated for oversedation, and in 7 cases (37%), for opioid-induced respiratory depression. All patients received naloxone within the first 24 postoperative hours. While all patients survived the opioid-related adverse event, 2 patients were intubated, 1 developed stress-induced cardiomyopathy, and 5 required intensive care unit admission.
Conclusion: The rate of early postoperative opioid-induced respiratory depression or oversedation in our community hospital was low; however, these patients often require a substantial escalation of medical management.
