[Cardiopulmonary resuscitation with cardiopulmonary bypass for intraoperative cardiac arrest].

A 67-year-old man was scheduled for left upper lobectomy under epidural and general anesthesia. About 1 hour after the beginning of operation, he developed cardiac arrest due to sudden massive bleeding from the pulmonary artery. In spite of open chest cardiac massage and intravenous administration of epinephrine, we could not resuscitate him successfully. More than 30 minutes after the cardiac arrest, cardiopulmonary bypass (CPB) was started and mean arterial blood pressure was maintained at 50-60 mmHg. His pulmonary artery was repaired under CPB. One hour after CPB, the weaning from artificial circulation was attempted and the spontaneous beating was observed. However, he developed low cardiac output syndrome due to long time ischemia resulting in hemorrhagic infarction. Therefore, the intra-aortic balloon pumping was started and his hemodynamics was immediately restored. We presume that CPB is useful for intraoperative resuscitation and this gives us new application of advanced life support for the patient in whom the conventional technique is ineffective.
