Paravertebral Block Versus Intercostal Nerve Block in Non-Intubated Uniportal Video-Assisted Thoracoscopic Surgery: A Randomised Controlled Trial.

Background: Non-intubated uniportal video-assisted thoracoscopic surgery (VATS) has been reported to be safe and feasible for patients with various thoracic diseases, including those who have respiratory dysfunction. This study examined the anaesthetic and analgesic sparing effects of either paravertebral block or intercostal nerve block on the non-intubated technique with spontaneous ventilation in patients under general anaesthesia (GA) using a supraglottic airway device. The primary aim was to compare the anaesthetic sparing effect of paravertebral block versus intercostal nerve block in non-intubated GA with airway support via a supraglottic airway device during VATS surgery.
