QUESTION
In stage III surgical anaesthesia, which plane ends with cessation of eyeball movement?
OPTIONS
(A) Plane 1
(B) Plane 2
(C) Plane 3
(D) Plane 4
ANSWER
(A) Plane 1
EXPLANATION
In the traditional Guedel stages of general anesthesia, roving eyeball movements occur in early stage III and cease by the end of plane 1 as anesthesia deepens. Planes 2 through 4 represent progressively deeper anesthesia after that transition, rather than the plane that ends the movement.
