Abstract
BackgroundThis retrospective study evaluated the efficacy and safety of intraoperative methadone compared with short-acting opioids. MethodsPatients undergoing cardiac surgery with cardiopulmonary bypass (n=11 967) from 2018 to 2023 from a single health system were categorised into groups based on intraoperative opioid administration: no methadone (Group O), methadone plus other opioids (Group M+O), and methadone only (Group M). ResultsPatients in Groups M and M+O had lower mean pain scores until postoperative day (POD) 7 compared with Group O after adjusting for covariates (P<0.01). Both Groups M and M+O had lower total opioid administered compared with Group O for all days POD0–POD6 (all P<0.001). The median number of hours until initial postoperative opioid after surgery was 2.55 (inter-quartile range [IQR]=1.07–5.12), 6.82 (IQR=3.52–12.98), and 7.0 (IQR=3.82–12.95) for Group O, Group M+O, and Group M, respectively. The incidence of postoperative complications did not differ between groups. ConclusionsIntraoperative administration of methadone was associated with better pain control without significant side-effects after cardiac surgery.
