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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative Pain Score Using Visual Analog Scale (VAS) | postoperative 24 hours | 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. |
| Total Opioid Consumption in the First 24 Hours Postoperatively | Postoperative 24 hours | The total amount of opioids administered during the first 24 hours postoperatively will be recorded and converted to morphine milligram equivalents (MME). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to First Ambulation After Surgery | postoperative 24 hours | The time from the end of surgery to the patient's first ambulation will be recorded in hours. |
| Time to First Bowel Movement After Surgery | postoperative 24 hours | The time from the end of surgery to the patient's first reported bowel movement will be recorded in hours. |
| Incidence of Nausea and Vomiting | postoperative 24 hours | The presence of postoperative nausea and vomiting will be recorded within the first 24 hours after surgery. |
| Opioid Requirement Within After Surgery | postoperative 1 month | The need for opioid use within 1 month after discharge will be evaluated through follow-up phone calls. The percentage of patients requiring opioids during this period will be recorded. |
