Randomized Controlled Trial
The effect of intravenous dexamethasone on postoperative nausea and vomiting after Cesarean delivery with intrathecal morphine: a randomized-controlled trial.
Intrathecal morphine administered during spinal anesthesia for Cesarean delivery is associated with a high incidence of postoperative nausea and vomiting (PONV). Small studies performed to date provide conflicting evidence on the effectiveness of dexamethasone as prophylaxis in this setting, raising the possibility that efficacy may be linked to dose timing. This study hypothesized that intravenous dexamethasone given prior to intrathecal morphine during spinal anesthesia may reduce the incidence of PONV. ⋯ This trial does not support the use of dexamethasone prior to intrathecal morphine for PONV prophylaxis in Cesarean delivery.
