An anesthesiologist completes preoperative teaching for a patient the night before surgery. The patient asks the nurse to clarify the reason methohexital [Brevital] will be given as an adjunct to the anesthetic
Which statement by the patient indicates understanding? a. "Brevital allows a larger amount of in-haled anesthetic to be used without in-creased side effects."
b. "Brevital is given to enhance the analgesic and muscle relaxation effects of the in-haled anesthetic."
c. "Brevital is used to produce rapid uncons-ciousness before administration of the in-haled anesthetic."
d. "Brevital is used to reduce cardiovascular and respiratory depression caused by the inhaled anesthetic."
C
Methohexital [Brevital], a short-acting barbiturate, is given intravenously for induction of anes-thesia. It has a rapid onset and short duration and must be followed immediately by an inhalation anesthetic. It does not alter the side effects of inhalation anesthetics. Most adjuncts to inhalation anesthetics are given so that lower doses of the anesthetic may be used. Methohexital has very weak analgesic and muscle relaxation effects. Methohexital causes cardiovascular and respiratory depression.
