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.

Detailed description

This prospective, randomized, controlled study is designed to investigate the effects of preoperative dexmedetomidine and tramadol on perioperative anxiety, postoperative pain, and intraoperative hemodynamic parameters in patients undergoing hemorrhoidectomy under spinal anesthesia. Eligible patients aged 20-60 years with ASA physical status I-II scheduled for elective hemorrhoidectomy will be enrolled. After obtaining written informed consent, patients will be randomly allocated into three groups: dexmedetomidine group, tramadol group, and control group. Patients in the dexmedetomidine group will receive 1 µg/kg dexmedetomidine administered intravenously as a loading infusion over 10 minutes prior to spinal anesthesia. Patients in the tramadol group will receive 1 mg/kg tramadol administered intravenously as a loading infusion over 10 minutes prior to spinal anesthesia. The control group will receive 10 mL of 0.9% saline intravenously over 10 minutes before spinal anesthesia as placebo. Preoperative anxiety will be assessed using the State-Trait Anxiety Inventory (STAI). Postoperative pain will be evaluated using the Visual Analog Scale (VAS) at predefined time intervals. Intraoperative hemodynamic parameters, including heart rate and blood pressure, will be recorded throughout the procedure. The primary outcome of the study is the change in STAI scores from preoperative baseline to the postoperative period. Secondary outcomes include postoperative pain scores and intraoperative hemodynamic changes among the groups.

Masking description

The study is conducted in a double-blind manner. Study medications are prepared in identical opaque syringes by an anesthesiologist not involved in outcome assessment. Participants and investigators responsible for perioperative assessments are blinded to group allocation throughout the study period.

Intervention model description

Participants are randomly assigned to parallel groups to receive preoperative dexmedetomidine or tramadol before hemorrhoidectomy under spinal anesthesia.

Design outcomes

Primary

MeasureTime frameDescription
Change in Preoperative Anxiety Level (STAI-S Score)From baseline (one day before surgery) to immediately before spinal anesthesia on the day of surgeryEvaluation of changes in STAI-State (STAI-S) scores over time with respect to group effect, time effect, and group × time interaction.

Secondary

MeasureTime frameDescription
Postoperative Pain Score (VAS)4, 12, and 24 hours after surgeryPostoperative pain assessed using the Visual Analog Scale (VAS) at 4, 12, and 24 hours after surgery.
Intraoperative Hemodynamic ParametersDuring surgery, measured at 5-minute intervalsSystolic and diastolic blood pressure, heart rate, and oxygen saturation measured at 5-minute intervals during surgery.
Sedation Level (Ramsay Sedation Scale)0, 4, 12, and 24 hours after surgerySedation level assessed using the Ramsay Sedation Scale at 0, 4, 12, and 24 hours after surgery among study groups.
Additional Sedative RequirementFrom initiation of spinal anesthesia until the end of surgeryTotal dose of midazolam administered intraoperatively for sedation.
Postoperative Anxiety Level (STAI-S Score)24 hours after surgeryState-Trait Anxiety Inventory-State (STAI-S) score assessed postoperatively when Ramsay Sedation Score is ≤3 among study groups.
