Brief 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.

Interventions

Group Morphine: Spinal anesthesia will be applied to patients who will undergo caesarean section using a combination of 2 ml (10 mg) bupivacaine + 0.1 ml (100 mcg) morphine + 0.5 ml saline

PROCEDUREGroup morfin+dexamethasone

Group morfin+dexamethasone: Spinal anesthesia will be applied to patients who will undergo a caesarean section using a combination of 2 ml (10 mg) bupivacaine + 0.1 ml (100 mcg) morphine + 0.5 ml (2 mg) dexamethasone

Intervention model description

Spinal anesthesia will be administered to 120 pregnant patients scheduled for elective cesarean section, using either a combination of 2 mL (10 mg) bupivacaine, 0.1 mL (100 mcg) morphine, and 0.5 mL saline, or a combination of 2 mL (10 mg) bupivacaine, 0.1 mL (100 mcg) morphine, and 0.5 mL (2 mg) dexamethasone, depending on the group to which they are randomized.

Design outcomes

Primary

MeasureTime frameDescription
Postoperative nausea-vomitingFor 24 hours after surgeryThe incidence of postoperative nausea and vomiting will be scored from 0 to 3. No nausea or vomiting attacks will be graded as 0, a nausea attack that resolves without treatment will be graded as 1, recurrent nausea attacks that resolve with treatment will be graded as 2, and persistent nausea or vomiting attacks will be graded as 3.
Postoperative itchingFor 24 hours after surgeryThe degree of pruritus will be assessed on a scale of 0 to 3, with 0 being categorized as no pruritus; 1 as mild pruritus; 2 as moderate pruritus; and 3 as severe pruritus.

Secondary

MeasureTime frameDescription
Intraoperative Mean Blood PressureIntraoperatively every 5 minutesMean blood pressure will be measured every 5 minutes intraoperatively using a noninvasive method.
Intraoperative Heart RateIntraoperatively every 5 minutesHeart rate will be measured every 5 minutes intraoperatively using a noninvasive method
