Laparoscopic appendectomy causes postoperative pain. The primary objective of this prospective randomized controlled study is to compare the effect of ultrasound (US)-guided quadratus lumborum block (QLB) on 24-hour cumulative opioid requirements with transversus abdominis plane (TAP) block.
168 patients (ASA I-II-III) between 18 and 65 years of age, who were to undergo laparoscopic appendectomy, were randomized and divided into two groups. 32 patients were dropout for different reasons.(68 patients in each of the TAP block and QLB block groups). TAP block was performed for TAP group and QLB block was performed for QLB group. Postoperative analgesia was provided by intravenous tramadol hydrochloride using a patient-controlled analgesia device. 24-hour total tramadol hydrochloride consumption was primary outcome measure.Postoperative numeric rating scale values were the secondary outcome measure.

Postoperative 24-hours total tramadol hydrochloride consumption
This will be measured by pca device in the 24 hour after
Time frame: 24 hours postoperatively
Numerical rating scale (NRS) scores of patients
Numerical rating scale (NRS) at 1, 6, 12, 18, 24th hours. A numerical rating scale (NRS) requires the patient to rate their pain on a defined scale. For example, 0-10 where 0 is no pain and 10 is the worst pain imaginable.
Time frame: 24 hours postoperatively
