Retrolaminar Block for Postoperative Analgesia in Lumbar Herniectomy Surgery

Study Overview
=================
Brief Summary
-----------------
This retrospective study included 30 patients scheduled for lumbar herniectomy under general anesthesia. The patients were randomized to receive either retrolaminar block or intravenous analgesia treatment.Numeric Pain Rating Scale (NPRS) was used to measure the pain intensity of patients in postoperative period. Postoperative analgesic requirements were recorded to asses effectiveness of regional anesthesia.Opiod and NSAİD as rescue medication were recorded postoperatively.

Detailed Description
-----------------
This retrospective study included 30 patients scheduled for lumbar herniectomy under general anesthesia. The patients were randomized to receive either RLB or intravenous analgesia treatment. All patients were routinely monitored and their heart rate, blood pressure and pulse oxymetry recorded during the anesthesia. Numeric Pain Rating Scale (NPRS) scores evaluated at 2, 8, 12, 24 and 48 h after the surgery. Opiod and NSAİD as rescue medication were recorded postoperatively

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| postoperative pain: Numeric Pain Rating Scale | Pain intensity of patients with the Numeric Pain Rating Scale after surgery. The Numerical Pain Rating Scale is a subjective measure in which individuals rate their pain on an eleven-point numerical scale. Zero means the lowest score and no pain.Ten means the highest score and worst pain experienced. | at the second hour after the surgery |
