ABSTRACT
A 23-month-old male patient with treated bronchitis underwent a surgery for the repair of bilateral Hutch's diverticulum of bladder under general anesthesia. He treated bronchitis during 2 weeks since 3 weeks before operation. Arriving operating room, he had mild coughing with sputum. During anesthesia, he was well ventilated but endotracheal secretion was profuse. At ABGA of 2 hours after starting anesthesia, severe hypercapnea(PaCO2: 190.2 mmHg) and severe acidosis(PH: 6.746) were checked. Active treatment was done by suction of endotracheal secretion, hyperventilation, PEEP(5~10 cmH2O), increasing fresh gas flow rate(3.6 L/min --> 7 L/min), and administration of sodium bicarbonate, orciprenaline sulfate and methyl- prednisolone. After 3 hours of treatment, ABGA was normalized and symptoms including wheezing were relieved.
