Bilateral Continuous Erector Spinae Plane Block Contributes to Effective Postoperative Analgesia After Major Open Abdominal Surgery: A Case Report
The erector spinae plane (ESP) block is a regional anesthetic technique involving local anesthetic injection in a paraspinal plane deep to the erector spinae muscle. Originally described for thoracic analgesia when performed at the T5 transverse process, the ESP block can provide abdominal analgesia if performed at lower thoracic levels because the erector spinae muscles extend to the lumbar spine. A catheter inserted into this plane can extend analgesic duration and can be an alternative to epidural analgesia. In this report, we describe using bilateral ESP catheters inserted at the T8 level to provide effective perioperative analgesia for major open lower abdominal surgery.
