With brand new anaesthetic machines and patient monitors, electrosurgical equipment, endoscopes, multiple safety measures e.g. 2 theatre lights with one on UPS, spare anaesthetic machine, multiple suction machines, spare diathermy machines, piped oxygen supply, ventilator.
Why can't I eat or drink before surgery? The likelihood that a patient will vomit during the anesthetic is increased with a short time interval between eating or drinking and the surgery. The most likely times for someone to vomit are going to sleep and waking up. Your risk of having a complication is increased if these events occur. The exception to this is emergency surgery, and special precautions will be taken to minimize the risk.
