Induction of anaesthesia
Abstract
General anaesthesia is a temporary state of unconsciousness that is
induced to facilitate a therapeutic procedure. Induction is the first stage
of a sequential process. It commences with patient preparation and
assessment away from theatre, and continues in the safe and monitored
environment of the anaesthetic room or operating theatre, where the
administration of drugs and airway interventions take place. The anaesthetic
then transits through maintenance, emergence and recovery
phases. The exact mechanism of induction-whether it be intravenous,
inhalational or rapid sequence induction-depends on the needs of the patient
and the procedure planned. As general anaesthesia is seldom a therapeutic
intervention in itself, it is essential that inherent risks to the
patient are minimized.
