Perioperative Erector Spinae Plane Block in Thoracoscopic Surgery

Study Overview
=================
Brief Summary
-----------------
The erector spinae plane block (ESPB) is a novel myofascial plane block. The ESPB is targeted at anterior surface of the erector spinae plane, which is oriented cephalocaudally to the spinal transverse process. Local anaesthetic injected in this plane can block the dorsal rami and ventral rami and intercostal nerves. The aim of this study was to evaluate the effect of ESPB on postoperative pain in thoracic surgery.

Detailed Description
-----------------
The erector spinae plane block (ESPB) is a newly defined regional anesthesia technique for thoracic analgesia. The blocks were performed at the T5 level of the spine using an in-plane approach.Previous studies were not designed as randomized controlled trial. In this study, the efficacy of ESPB is to confirm with randomized controlled trial design. ESPB will be performed in video assisted thoracoscopy preoperatively. After the surgery, the efficacy of ESPB will be assessed.
