Title: Efficacy of Serratus Anterior Plane (SAP) Block Versus Erector Spinae Plane (ESP) Block for Quality of Recovery After Video Assisted Thoracic Surgery : A Randomised Control Trial
Brief Summary: During VATS (Video assisted thoracic surgery) small incisions are made in the patient's chest through which a camera and instruments are inserted to allow a lung operation to be performed. Often patients experience a substantial amount of pain and difficult recovery after this type of operation. Anaesthesiologists sometimes use "Regional Anaesthesia" to minimise the pain and help patient recovery after the operation. This involves injecting local anaesthesia into the nerves around the chest wall to effectively numb that part of the chest. There is a variety of different locations on the chest wall where the local anaesthetic can be deposited and no study has measured whether one technique is better than the other in terms of improving patients' recovery experience. Our study compares two new techniques for Regional Anaesthesia after this type of surgery. Participants will be randomly assigned (like tossing a coin) to receive either a SAP (Serratus Anterior Plane) or ESP (Erector Spinae Plane) Block. Both techniques are described within last five years, but have never been compared for chest surgery
