Postoperative Pain Clinical Trial
Official title:
Optimal Dose of Intrathecal Morphine for Postoperative Analgesia After Cesarean Delivery
This is a randomized double blinded non-inferiority study comparing the duration of pain relief when patients receive one of three doses of spinal morphine. Enrolled patients will be randomly assigned to receive either 50 mcg, 150 mcg, or 250 mcg. All patients will receive standardized postoperative care, including multimodal analgesia. The primary outcome will be the time until the patient requests additional opioid pain medications.
