BackgroundDexamethasone is an effective analgesic and anti-emetic in patients undergoing many surgical procedures but its effects on pain after cesarean delivery are poorly studied. The aim of this study was to evaluate if routine intra-operative administration of dexamethasone improved analgesia and decreased postoperative nausea and vomiting after scheduled cesarean delivery.MethodsElectronic medical record data for scheduled cesarean deliveries performed under neuraxial anesthesia, before and after a practice change that introduced the routine use of intravenous dexamethasone 4 mg, were obtained. Patients were analyzed based on whether they received routine care (n=182) or also received dexamethasone (n=187). The primary outcome was time to first opioid use. Secondary outcomes included postoperative opioid consumption, pain scores, incidence and treatment of postoperative nausea and vomiting, satisfaction and length of stay.ResultsThere was no significant difference between groups in median time to first postoperative opioid administration (15.8 [3.4-48.0] h routine care vs 14.7 [3.2-38.8] h routine care plus dexamethasone, P=0.08). There were no significant differences in any secondary outcomes.ConclusionsThis impact study involving more than 360 patients suggests that routine administration of intra-operative intravenous dexamethasone 4 mg does not provide additional analgesic benefit after scheduled cesarean delivery, in the context of a multimodal postoperative analgesic regimen. Studies are required to determine if a larger dose or repeated administration influence postoperative analgesia or side effects, or whether certain subsets of patients may benefit.Copyright © 2019 Elsevier Ltd.
