“…To date, VATS is always performed under general anesthetic with endotracheal intubation and selective one-lung ventilation by surgical and anesthesia teams (thoracic surgeon, scrub nurse, anesthesiologist and residents or assistants), in a fully equipped operating theater. In contrast, MT is routinely performed by chest physicians under light sedation (or so-called ‘conscious sedation’) in spontaneously breathing patients in facilities outside the costly environment of operating rooms [5,6,7,8]. Among nonanesthesiologists, midazolam remains the preferred sedative drug, although gastrointestinal endoscopists have gained much experience with the administration of propofol [9,10,11,12,13].…”
