Recovery from outpatient anaesthesia. Factors affecting outcome.

In 1994, 66% of all surgery in the USA was performed as ambulatory surgery. Day surgery is also expanding to other countries worldwide. To provide safe anaesthesia and good outcomes for longer and more extensive operations performed in ambulatory facilities, patients must be carefully evaluated before surgery, their home readiness must be assessed, and they must fully understand all relevant information. Good outcome requires adoption of policies for safe discharge from the hospital. If a patient does not have an escort home, the surgical procedure should be cancelled or the patient admitted to the hospital. As the number of patients and complexity of scheduled surgical procedures increases, the outcome of day surgery will increasingly depend on the anaesthetist's skills. The recently introduced short-acting drugs may further improve the outcome after day surgery by facilitating rapid recovery and an early return to normal daily activities.
