Anaesthesia
General anesthesia consists of Four stages, each associated with specific clinical manifestation. When opioid agents (narcotics) and neuromuscular blockers (relaxants) are administered, several of the stages are absent. The anesthesis level consists of general anesthesia and spiral or major regional anesthesia but does not include anesthesias (JLAHO, 2001). Abesthesia is a state of narcosis (severe cestral nervous system depression produced by pharmacologic agents), analgesia relaxation, and reflex loss. patients under general stimuli. they lose the the ability to maintain ventilatopry function and require assistance in maintaining a patent airway. Cardiovascular function may be impaired as well (JCAHO, 2001).
