NCT06781177

Brief Summary

This study aims to compare the effects of the classical Total Intravenous Anesthesia (TIVA) method and multimodal anesthesia protocols created by adding lidocaine and ketamine infusions on postoperative pain management, opioid consumption, and surgical recovery in posterior thoracolumbar spinal fusion surgeries. A prospective observational study was conducted with 72 patients undergoing posterior thoracolumbar spinal fusion surgeries. Patients were evenly divided into three groups: classical TIVA (propofol and remifentanil), TIVA + ketamine, and TIVA + lidocaine. Hemodynamic parameters and drug dosages were recorded during the intraoperative period, while pain scores, opioid consumption, time to first ambulation and bowel movement, as well as nausea-vomiting and sedation scores, were documented postoperatively.

Outcome Measures

Primary Outcomes (2)

  • Postoperative Pain Score Using Visual Analog Scale (VAS)

    Pain levels will be assessed using the Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst imaginable pain), at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours postoperatively.

    postoperative 24 hours

  • Total Opioid Consumption in the First 24 Hours Postoperatively

    The total amount of opioids administered during the first 24 hours postoperatively will be recorded and converted to morphine milligram equivalents (MME).

    Postoperative 24 hours

Secondary Outcomes (4)

  • Time to First Ambulation After Surgery

    postoperative 24 hours

  • Time to First Bowel Movement After Surgery

    postoperative 24 hours

  • Incidence of Nausea and Vomiting

    postoperative 24 hours

  • Opioid Requirement Within After Surgery

    postoperative 1 month
