NCT06860100

Brief Summary

This randomized controlled study aims to evaluate the effects of preoperative dexmedetomidine and tramadol on anxiety, pain, and hemodynamic parameters in patients undergoing hemorrhoidectomy under spinal anesthesia. Preoperative anxiety levels will be assessed using the State-Trait Anxiety Inventory (STAI), and postoperative pain will be evaluated using the Visual Analog Scale (VAS). Intraoperative hemodynamic parameters will also be recorded and compared among the study groups.

Outcome Measures

Primary Outcomes (1)

  • Change in Preoperative Anxiety Level (STAI-S Score)

    Change in State-Trait Anxiety Inventory-State (STAI-S) scores from baseline (one day before surgery) to immediately before spinal anesthesia on the day of surgery among study groups.

    From baseline (one day before surgery) to immediately before spinal anesthesia on the day of surgery

Secondary Outcomes (5)

  • Postoperative Pain Score (VAS)

    0, 4, 12, and 24 hours after surgery

  • Intraoperative Hemodynamic Parameters

    During surgery, measured at 5-minute intervals

  • Sedation Level (Ramsay Sedation Scale)

    0, 4, 12, and 24 hours after surgery

  • Additional Sedative Requirement

    From initiation of spinal anesthesia until the end of surgery

  • Postoperative Anxiety Level (STAI-S Score)

    24 hours after surgery
