Efficacy and safety of Extrapleural block in patients with coronary artery disease after thoracoscopic surgery.

Objective: This study aimed to investigate the efficacy and safety of extrapleural block (EPB) application in patients with coronary artery disease after thoracoscopic surgery.

Methods: Patients with typical symptoms of angina and myocardial ischemia who underwent thoracoscopic surgery at our institution between December 2018 and December 2020 were screened for eligibility and they received paravertebral blocking (PVB), EPB, and patient-controlled intravenous analgesia (PCIA). Visual analog scale (VAS) scores were used to assess the analgesic effect and safety outcomes included heart rate, incidence of postoperative rescue analgesics, cardiac complications, and adverse reactions such as nausea and vomiting.
