Deep Serratus Anterior Plane Block for Multimodal Analgesia in Minimally Invasive Mitral Valve Surgery Performed via Right Anterior Mini-Thoracotomy.

Objective: This study investigated if the serratus anterior plane block (SAPB) within a multimodal analgesia scheme would reduce acute post-operative pain and intravenous opioid consumption in patients admitted to the intensive care unit after isolated minimally invasive mitral valve surgery.

Design: Retrospective study.
