    Abstract:
    OBJECTIVE: To investigate the effect of intrathecal dexamethasone administered with intrathecal morphine at cesarean delivery on postoperative adverse effects and patient satisfaction. METHODS: A triple-blind, randomized, placebo-controlled trial conducted between February 2008 and December 2009 of 120 pregnant women scheduled to undergo cesarean delivery. The patients were randomized into 2 groups: group 1 received 0.2mg of intrathecal morphine plus 8 mg of intrathecal dexamethasone, while group 2 received 0.2mg of intrathecal morphine plus 0.9% saline solution (placebo). The occurrence of postoperative nausea and vomiting (PONV), postoperative itching, number of vomiting attacks, and need for antiemetics were recorded in both groups. Overall patient satisfaction was also recorded. RESULTS: PONV was 3 times less likely to occur in the dexamethasone group than in the placebo group. When vomiting did occur, the number of attacks was lower in the dexamethasone group (23 vs 87 attacks; OR 0.26, 95% CI, 0.18-0.39). Administration of antiemetics was markedly lower in the dexamethasone group (18 vs 49 shots; OR 0.10, 95% CI, 0.04-0.23) and less postoperative itching was experienced (OR 0.39; 95% CI, 0.19-0.81). The dexamethasone group reported significantly higher mean overall satisfaction scores (77 ± 17 vs 51 ± 22; mean difference 26.00; 95% CI, 18.97-33.03). CONCLUSION: Intrathecal administration of dexamethasone with morphine significantly decreased PONV and improved overall patient satisfaction after cesarean delivery.
