Postoperative Analgesia y After Uniportal Video-assisted Thoracoscopic Surgery

Comparison of Surgical Thoracoscopic Intercostal Nerve Block and Ultrasound-guided Erector Spinae Plane Block for Postoperative Analgesia and Enhanced Recovery After Uniportal Video-assisted Thoracoscopic Surgery: a Double-blinded, Randomized Controlled Trial

Ultrasound-guided erector spinae plane block (ESPB) is an interfascial blockade during thoracic anesthesia, first described by Forero in 2016, and is highlighted by technically feasibility and less complication rate. The patient is placed as decubitus position. The anesthesiologists use echo to identify the ipsilateral transverse process at T5 level, and insert the needle to 2-3 cm lateral to the spinous process until contact the transverse process. Then the injected local anesthetic will penetrate via erector spinae muscle to paravertebral space to affect and relieve pain.
