The Efficacy of Intrathecal Morphine Versus Intrathecal Morphine+Dexamethasone Combination added to bupivacaine in elective cesarean section under spinal anesthesia
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.
Exclusion Criteria:
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.
Procedure: Group morphine
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.
Procedure: Group morfin+dexamethasone
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
Also known as: Group I
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
Also known as: Group II
Postoperative nausea-vomiting
The 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.
Time frame: For 24 hours after surgery
Postoperative itching
The 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.
Time frame: For 24 hours after surgery
Intraoperative Mean Blood Pressure
Mean blood pressure will be measured every 5 minutes intraoperatively using a noninvasive method.
Time frame: Intraoperatively every 5 minutes
Intraoperative Heart Rate
Heart rate will be measured every 5 minutes intraoperatively using a noninvasive method
Time frame: Intraoperatively every 5 minutes
