A Fluotec vaporizer is set to administer halothane 4% using a fresh gas flow of 4 L/min. If the diluent gas flow is increased to 8 L/min, and at the same time the room temperature increases from 20 to 25°C, the approximate concentration of halothane delivered to the patient would be

A 23-year-old man who is receiving his first anesthetic has not resumed spontaneous ventilation two hours after receiving succinylcholine. The train-of-four monitor shows no twitch response. Which of the following is the most likely cholinesterase genotype in this patient?

ADVANCED Pharmacology & Pharmacokinetics General

During induction of anesthesia for cesarean delivery, pancuronium is inadvertently substituted for succinylcholine. The neonate shows no clinical signs of muscle relaxation because pancuronium is
