Study 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.

Read the 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

What researchers measure

Primary outcomes

  1. 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.

    Time frame: at the second hour after the surgery

  2. postoperative pain: Numeric Pain Rating Scale

    pain intensity of patients with the Numeric Pain Rating Scale after surgery. 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.

    Time frame: at the eighth hour after the surgery
