title: [A case of apnea during spinal anesthesia after intravenous injection of sedatives].
abstract: During spinal anesthesia for appendectomy (sensory level: -Th7), apnea occurred for about 20 minutes by intravenous administration of diazepam. Since the patient showed hyperventilation sign before the incident, this apnea might be caused by low PaCO2 and stopping respiratory stimulation from psychological unrest when diazepam, pentazocine and droperidol were administered. In the postoperative period, this patient showed normal neurologic and psychosomatic functions. In such a case as this, long duration of apnea might damage brain by severe hypoxia. Apnea after hyperventilation during spinal anesthesia as observed in this case could lead to a serious accident.
