Comparison of USG- Guided Modified Pectoral Nerve Block and Erector Spinae Plane Block on Postoperative Analgesia in Video Assisted Thoracoscopic Surgery

Study Overview
=================
Brief Summary
-----------------
This study aims to compare the effects of the erector spinae plan block (ESP) and modified pectoral nerve block (PECS II) on postoperative analgesia in patients undergoing video- assisted thoracoscopic surgery (VATS).

Detailed Description
-----------------
55 patients (ASA I-II-III) between 18 and 65 years of age, who were to undergo VATS, were randomized and divided into two groups. (26 patients in each of the PECS and ESP groups). Three patients were excluded from the study because thoracotomy was performed. ESP block was performed for ESP group and a modified pectoral nerve block was performed in the PECS group. Postoperative analgesia was provided by intravenous morphine infusion using a patient-controlled analgesia device. Postoperative 24-hour total morphine consumption and duration of analgesia were the primary outcome measure. Perioperative remifentanil use, numeric rating scale values, time of the first analgesic request, and additional analgesic consumption were recorded.
