A 4-year-old child with myelomeningocele and a ventriculoperitoneal shunt is scheduled for bladder augmentation. One year ago, hypotension and bronchospasm occurred during laparotomy for placement of a feeding gastrostomy and responded to fluids and epinephrine. At that time, anesthesia was induced with thiopental, the trachea was intubated with a polyvinyl tracheal tube following administration of succinylcholine, and anesthesia was maintained with halothane and nitrous oxide. No diagnostic tests were performed after that incident. Which of the following should be avoided during the bladder augmentation?

A 50-year-old patient is undergoing middle ear exploration with isoflurane, nitrous oxide, and oxygen anesthesia. Ventilation is controlled; PetC02 is 35 mmHg, heart rate is 90 bpm, and blood pressure is 120/70 mmHg. Assistance is needed to minimize bleeding in the surgical field. Which of the following is the most appropriate next step in management?
Depression of cerebral oxygen requirements below the level required to create an isoelectric EEG can be achieved by
One hour after an open cholecystectomy, a 42-year-old patient is hemodynamically stable and breathing spontaneously (rate 10/min and regular) at an FiO2 of 0.4. Fentanyl, isoflurane, nitrous oxide, and pancuronium were used during the procedure. Analysis of arterial blood gases (pH, pCO2, pO2) is most likely to show:
