What are the principal risks associated wtih ECT?
General anesthesia with neuromuscular blockade
Consequences of sympathetic stimulation.
both
neither
What is/are the most hazardous response to sympathetic stimulation?
tachycardia
arrhythmias
hypertension
A & C
A, B & C
How can sympathetic overstimulation be to a substantial degree prevented?
An anesthetic induction agent such as thiopental will substantially reduce the risk of hypertension.
Administer hydralazine to the patient
use a long-acting alpha-receptor blocker
use a long-acting beta-receptor blocker
none of the above
In this case, how is tachycardia best controlled?
administer atropine before the procedure
administer hexamethonium before the procedure
use a selective beta1 adrenergic blocking agent prior to seizure production
infuse acetylcholine
By what route of administration should esmolol (Brevibloc) begin to this patient?
