Официальное название

A Randomized Comparative Study of Dexmedetomidine Versus Labetalol in Attenuating Airway Stress Response in Hypertensive Patients Undergoing Craniotomy

Обзор

This randomized trial compares dexmedetomidine and labetalol in controlling airway and hemodynamic stress during extubation in hypertensive patients undergoing craniotomy. Outcomes include extubation quality, vital signs, sedation, and adverse effects.

Подробное описание

A. Preoperative Settings:

Patients will undergo standard pre-anesthetic assessment, including review of medical history, fasting status, and laboratory investigations. Eligibility will be confirmed based on inclusion and exclusion criteria. After obtaining informed consent, patients will be randomly assigned into two groups using a computer-generated randomization table and sealed envelopes.

B. Intraoperative and Postoperative Settings:

All patients will receive standardized general anesthesia with continuous monitoring. Following completion of surgery and while still under anesthesia, the study drug (either dexmedetomidine or labetalol) will be administered over 10 minutes. Extubation will be performed thereafter.

Hemodynamic parameters including arterial blood pressure and heart rate will be recorded at baseline, during drug administration, and at specific intervals post-extubation. Extubation quality will be assessed using a five-point scale, and sedation levels using the Richmond Agitation-Sedation Scale. Adverse events such as hypotension, bradycardia, or respiratory issues will be documented and managed as per protocol.

This structured approach aims to evaluate which agent provides better control of stress responses during emergence from anesthesia in hypertensive patients undergoing craniotomy.

Вмешательства

  • Препарат Dexmedetomidine
    Participants in this arm will receive dexmedetomidine at a dose of 0.5 mcg/kg, diluted with normal saline to a total volume of 50 mL. The solution will be administered intravenously via a syringe pump at an infusion rate of 300 mL/hour, completing over 10 minutes immediately prior to extubation.
  • Препарат Labetalol
    Participants in this arm will receive labetalol at a dose of 0.5 mg/kg, diluted with normal saline to a total volume of 50 mL. The solution will be administered intravenously via a syringe pump at an infusion rate of 300 mL/hour, completing over 10 minutes immediately prior to extubation.
