Minimally invasive cardiothoracic surgery is often associated with chronic pain syndrome, out of keeping with the extent of surgical dissection. This is thought to be because of damage to the intercostal nerves by compression and traction by the surgical equipment. Cryoanalgesia is long-standing technique that freezes nerves locally to temporarily block pain sensation, which is currently used to treat acute post-operative pain in lung dissections and the Nuss procedure. We intend to perform a trial to assess whether using cryoanalgesia on intercostal nerves intraoperatively, reduces post-operative pain following minimally invasive cardiothoracic surgery.
