Factual error: During the operation, one of the surgeons asks the anaesthetist what he'd used for anaesthesia, to which the anaesthetist replies, "Midazolam and Fentanyl". Although these drugs are used in anaesthesia, often on induction, they are not themselves induction agents and would not cause a patient to appear anaesthetised. Also, on the monitors it shows arterial line tracings, and no sign of an arterial line (however the radial artery in the wrist is often used, so may be covered up), but the CVP is also shown on the monitor, and this is definitely absent from the patient as it would be in his neck.

Factual error: The endotracheal tube (breathing tube) was not secured to the patient. It is standard practice to secure this tube to the patient in order to keep it in place.
