Brief Summary
This study will compare two different methods of pain management in patients undergoing video-assisted thoracoscopic surgery (VATS). One group will receive a combination of spinal morphine, nerve block, and dexmedetomidine, while the other group will receive a nerve block and dexmedetomidine without spinal morphine. All patients will receive standard pain medications after surgery. The purpose is to see if adding spinal morphine improves pain control and recovery after surgery.

Outcome Measures
Primary Outcomes (1)
Quality of Recovery-15 (QoR-15) Score
The Quality of Recovery-15 (QoR-15) questionnaire is a validated 15-item instrument that assesses patient-centered postoperative recovery, including pain, physical comfort, emotional state, and overall wellbeing. The total score ranges from 0 to 150, with higher scores indicating better recovery.
Measured 24 hours after surgery
Secondary Outcomes (11)
Time to First Rescue Opioid
Within 24 hours postoperatively
Postoperative Pain Scores (VAS)
From postoperative hour 2 to hour 24.
Total Opioid Consumption
24 hours postoperatively
Intraoperative Complications
During surgery
Postoperative Adverse Effects
24 hours postoperatively

Study Arms (2)
ITM + SAPB + Dex
EXPERIMENTALBefore induction, 200 µg intrathecal morphine via a 27G Sprotte spinal needle from L3-L4; intraoperative 1 g paracetamol IV and 50 mg dexketoprofen IV; dexmedetomidine 0.5 µg/kg loading (15 min) followed by a 0.5 µg/kg/h infusion; unilateral SAPB with 30 mL of 0.25% bupivacaine under ultrasound guidance at the end of surgery; basal tramadol PCA without infusion IV in the PACU (20 mg each bolus, maximum 200 mg/24 h); if necessary, 50 mg tramadol IV for VAS\>4.
SAPB + Dex (No ITM)
ACTIVE COMPARATORSame protocol, but no intrathecal morphine. Intraoperatively, 1 g paracetamol IV and 50 mg dexketoprofen IV; dexmedetomidine 0.5 µg/kg loading dose (15 min) followed by a 0.5 µg/kg/h infusion; unilateral SAPB with 30 mL of 0.25% bupivacaine at the end of surgery; basal intravenous tramadol PCA (20 mg each bolus, maximum 200 mg/24 h) in the PACU; if necessary, 50 mg tramadol IV for VAS \>4.
Interventions
200 µg morphine sulfate, single-dose via L3-L4, 27G Sprotte spinal needle, prior to induction.
Ultrasound-guided unilateral SAPB at end of surgery with 30 mL 0.25% bupivacaine.
Loading dose 0.5 µg/kg over 15 minutes, then 0.5 µg/kg/h continuous infusion intraoperatively.
