Summary

This randomized controlled trial evaluated the effects of intraoperative intravenous magnesium sulfate versus dexmedetomidine on postoperative pain, analgesic consumption, hemodynamic stability, and respiratory function in patients undergoing elective transurethral resection of bladder tumor (TUR-M) under spinal anesthesia. Magnesium sulfate significantly reduced postoperative pain scores, delayed the time to first analgesic request, and decreased total analgesic consumption compared to dexmedetomidine and control groups, while both agents were hemodynamically and respiratorily safe.

Conditions

  • Bladder Tumors
  • Spinal Anesthesia
  • Postoperative Pain
  • Magnesium Sulfate
  • Dexmedetomidine
  • Hemodynamic and Respiratory Monitoring

Interventions

DRUG

magnesium sulfate

Patients receive intravenous magnesium sulfate at 15 mg/kg/hour during TUR-M surgery under spinal anesthesia. The calculated dose is diluted in 50 mL of 0.9% sodium chloride and infused intravenously throughout the surgery. Postoperative analgesia is provided as rescue treatment based on VAS scores.

DRUG

Dexmedetomidine

Patients receive intravenous dexmedetomidine at 0.5 µg/kg/hour during TUR-M surgery under spinal anesthesia. The calculated dose is diluted in 50 mL of 0.9% sodium chloride and infused intravenously throughout the surgery. Postoperative analgesia is provided as rescue treatment based on VAS scores.

DRUG

Normal Saline

Patients receive 15 mL/kg/hour of 0.9% sodium chloride without active pharmacological agents during TUR-M surgery under spinal anesthesia. Infusion is administered using the same protocol and devices as the experimental arms to maintain blinding. Postoperative analgesia is provided as rescue treatment based on VAS scores.
