Dexmedetomidine vs Tramadol to reduce anxiety, pain, and stabilize hemodynamics during hemorrhoidectomy

A Randomized Double-Blind Study Comparing the Effects of Preoperative Dexmedetomidine Versus Tramadol on Anxiety, Pain, and Hemodynamics in Patients Undergoing Hemorrhoidectomy

NA · Yuzuncu Yil University · NCT06860100

This study tests whether a single IV dose of dexmedetomidine or tramadol given before spinal anesthesia can lower anxiety, reduce postoperative pain, and keep heart rate and blood pressure stable in adults having hemorrhoidectomy.

What this trial studies

This is a prospective, randomized, controlled trial that randomly assigns adults undergoing elective hemorrhoidectomy under spinal anesthesia to receive preoperative dexmedetomidine, tramadol, or no premedication. Dexmedetomidine is given as a 1 µg/kg IV loading infusion over 10 minutes and tramadol as 1 mg/kg IV over 10 minutes prior to spinal anesthesia. Preoperative anxiety is measured with the State-Trait Anxiety Inventory (STAI), postoperative pain with the Visual Analog Scale (VAS) at predefined intervals, and intraoperative hemodynamics (heart rate and blood pressure) are recorded throughout the procedure. The primary outcome is change in STAI from baseline; secondary outcomes include VAS pain scores and intraoperative hemodynamic changes.

Who should consider this trial

Good fit: Adults aged 20–60 years with ASA physical status I–II scheduled for elective hemorrhoidectomy under spinal anesthesia who can provide informed consent are ideal candidates.

Not a fit: Patients outside the 20–60 age range, with ASA III or higher, severe hepatic or renal disease, contraindications to spinal anesthesia, or known allergy to dexmedetomidine or tramadol are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the intervention could reduce perioperative anxiety and postoperative pain while improving hemodynamic stability for patients having hemorrhoidectomy.

How similar studies have performed: Previous perioperative studies in other surgical settings have shown that dexmedetomidine and tramadol can reduce anxiety and postoperative pain, but direct comparisons specifically in hemorrhoidectomy are limited.
