Effect of Preop and Postop ESP Block on Analgesia, Hemodynamics and Patient Satisfaction in Laparoscopic Cholecystectomy

Erector spinae plane (ESP) block is an interfascial plane block applied to the paraspinal region, which provides effective visceral and extensive somatic analgesia by providing paravertebral spread of the administered local anesthetic to three and four vertebral levels cranial and caudal. ESP block is a new regional anesthesia method applied with ultrasound (USG) guidance to provide analgesia for various surgeries and for acute or chronic pain. The application of this block is simple and can be performed in the preoperative waiting area with light sedation or no sedation. ESP block can be applied with a single injection or as a continuous infusion by catheter placement. The first report related to this block was published in 2016; the block was performed to reduce thoracic neuropathic pain in a patient with metastatic rib disease and rib fracture. So far, the block has been reported to be performed successfully in many cases, including the Nuss procedure, thoracotomies, percutaneous nephrolithotomies, ventral hernia surgeries, and even lumbar fusions.
