Hypoventilation and hypokalemia in a patient with poor oral intake in the postanesthesia care unit -A case report-

초록

We encountered a case of hypoventilation and hypokalemia in a patient with poor oral intake in the postanesthesia care unit (PACU). A 44-year-old woman underwent a total abdominal hysterectomy under general anesthesia. She was transferred to the PACU after 2 hr of surgery. After 11/2 hr, the patient exhibited hypoventilation,muscle weakness, and mental changes. She was reintubated and transported from the PACU to the intensive care unit. The arterial blood gas analysis results were as follows: pH, 7.27; PaCO2, 65mmHg; PaO2, 68 mmHg; and serum potassium levels, 2.48 mmol/L. After 6 hr, she recovered with full consciousness.
