Summary

The Efficacy of Intrathecal Morphine Versus Intrathecal Morphine+Dexamethasone Combination added to bupivacaine in elective cesarean section under spinal anesthesia

Detailed description

The study will be designed as a double-blind, randomized clinical trial and will be conducted following approval by the local ethics committee. A total of 120 patients, aged 18-40 years, with an ASA physical status of II and scheduled for elective cesarean section, will be included. All patients will undergo standard preparation for spinal anesthesia. Two large-bore intravenous lines will be inserted in each patient upon arrival in the operating room. Participants will be randomly assigned to one of two groups (n = 60 per group) using sealed opaque envelopes. Group I (morphine group) will receive spinal anesthesia consisting of 2 mL (10 mg) bupivacaine, 0.1 mL (100 mcg) morphine, and 0.5 mL saline. Group II (morphine+dexamethasone group) will receive a mixture of 2 mL (10 mg) bupivacaine, 0.1 mL (100 mcg) morphine, and 0.5 mL (2 mg) dexamethasone. Intraoperative hemodynamic parameters (including age, height, and weight), ASA scores, postoperative complications (such as nausea, vomiting, and pruritus), and postoperative pain levels will be recorded and analyzed.
