Postoperative Pain for Patients After TA-BSM

Wenlong Yao (101480)197 enrolled

Overview

To retrospectively analyze the intraoperative and postoperative status of patients with hypertrophic cardiomyopathy undergoing TA-BSM, and to estimate whether paravertebral nerve block can improve postoperative pain for these patients.

Since conventional septal myectomy can be only assessed when the heart resumes beating, and the complications induced by cardiopulmonary bypass are inevitable, a novel transapical beating-heart septal myectomy (TA-BSM) has been invented, which provides real-time evaluation to guide resection while reducing surgical trauma. Postoperative pain after TA-BSM is unknown. Whether paravertebral nerve block can improve postoperative pain caused by TA-BSM is the objective of our study.
