Comparison of Erector Spinae Block and Combined Deep and Superficial Serratus Anterior Plane Block

Comparision of the Effects of Ultrasound-guided Erector Spinae Block and Combined Deep and Superficial Serratus Anterior Plane Block on Perioperative Analgesia for Video-assisted Thoracoscopic Surgery.

Objective: The authors hypothesized that combined deep and superficial serratus anterior plane block (SAPB) is as effective as erector spinae plane block (ESPB) for intraoperative and postoperative analgesia for video-assisted thoracoscopic surgery.

Design: A prospective randomized controlled study. Participants: Adult patients undergoing elective video-assisted thoracoscopic surgery.

Interventions: Preoperative SAPB or ESPB implementation.

Plane blocks implemented on preoperative course on 35 patients for each group. Postoperative Visual Analogue Scale (VAS) scores (0-10), intraoperative and postoperative analgesic consumption was measured using Mann-Whitney test. In the postoperative phase, opioid side effects, complications related to plane blocks, mobilization time and length of hospital stay was recorded and measured.
