Acute Pain
Conditions
Brief summary
Video assisted thoracoscopic surgery (VATS) is a minimally invasive surgery to remove lesions from the thoracic cavity. It is associated with moderate pain which can lead to pulmonary complications after surgery. The Enhanced Recovery After Surgery (ERAS) and the European Society of Thoracic Surgeons recommended a multimodal analgesia approach to manage pain after VATS. Erector spinae block (ESB) is a popular analgesic block due to its ease of performance and wide coverage. It has been shown to be effective in randomized control trials. Recently, case reports on bi-level ESB are emerging, suggesting more effective analgesia compared to single level ESB. As there is no available data, the investigators are interested in conducting a randomized pilot study, comparing bi-level to single level ESB to gather baseline data for sample size calculation for a formal randomized trial.
