What is the primary pathophysiological component of syncope during dental extraction?
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?
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?
How does anxiety contribute to the development of syncope during dental extraction?
- Anxiety induces convulsions which lead to loss of consciousness
- Anxiety causes an increase in cerebral blood flow resulting in fainting
- Anxiety triggers an increase in heart rate leading to decreased blood supply to the brain
- Anxiety leads to redirection of blood flow from the brain to skeletal muscles (correct)
