An obese, 35-year-old man had an episode of coughing followed by vomiting during induction of anesthesia for arthroscopy of the left knee. Intense wheezing developed bilaterally over five minutes. PaO2 is 60 mmHg, PaCO2 is 42 mmHg, and pH is 7.35. Optimal management following intubation of the trachea includes

The lungs of a 7-kg infant are being ventilated with a volume-cycled ventilator at a rate of 20/min. The anesthetic circuit has a compressible volume of 5 ml/cm H2O, and the peak inspiratory pressure is 20 cmH2O. To achieve adequate ventilation, the ventilator tidal volume should be set at

BASIC Equipment & Physics Pediatric

A 65-year-old patient with compensated congestive heart failure undergoes resection of a large tumor of the temporal lobe. During the procedure, the brain is noted to protrude through the surgical incision. After increasing minute ventila- tion, which of the following is the most appropriate next step in management?


During isoflurane anesthesia, a 45-year-old patient with chronic asthma has wheezing, prolonged expiration, sinus tachycardia of 120 bpm, and premature ventricular contractions. Preoperative medication included cromolyn and theophylline (serum level 20 jag/ml). The most appropriate treatment is to administer
