This study compared two different methods of regional anesthesia, specifically the erector spinae plane block (ESP) and the retrolaminar block. The main objective was to determine their effectiveness in alleviating postoperative pain. Pain was monitored in patients after video-assisted thoracoscopic surgery (VATS). The study focused on postoperative pain conditions as the primary subject of investigation. The sponsors of this research were Hacettepe University and Gulhane Training and Research Hospital. The entire study has already been completed, but the results are not provided in this excerpt.
