Questions and Answers

What is the primary pathophysiological component of syncope during dental extraction?

Cerebral ischemia due to inadequate oxygenated blood supply to the brain (correct)

Anxiety-induced redirection of blood flow from the brain to skeletal muscles

Increased volume of blood in skeletal muscles causing decreased blood supply to the brain

Decreased venous return to the heart leading to reduced cerebral blood flow

What signs and symptoms indicate a slight decrease in cerebral blood flow during syncope?

Increased heart rate, feeling weak, cold skin, sweating

Convulsions, pale skin, weakness, unconsciousness

Light headedness, dizziness, tachycardia, palpitation (correct)

Nausea, cold skin, sweating, loss of consciousness

How does anxiety contribute to the development of syncope during dental extraction?

Anxiety induces convulsions which lead to loss of consciousness
