1. Question
What is the correct sequence for Guedel’s stages of anesthesia?
CorrectThe correct answer is A. Amnesia and analgesia; delirium and excitement; surgical anesthesia; medullary paralysis.
Amnesia and analgesia is the stage in which
induction occurs; preservation of protective reflexes, and this ends with loss of consciousness.
Delirium and excitement is the second stage
and consists of the presentation of involuntary
movements, obtunded reflexes, and ends with
the onset of total anesthesia. Nausea and vomiting are common in this stage. Surgical anesthesia is the third stage and is composed of
three planes—light, medium (ideal for surgical
procedures), and deep. Medullary paralysis is
very deep anesthesia with loss of cardiovascular
function and imminent death.IncorrectThe correct answer is A. Amnesia and analgesia; delirium and excitement; surgical anesthesia; medullary paralysis.
