[Perioperative management of patients with dilated cardiomyopathy].
Dilated cardiomyopathy (DCM) is defined as a syndrome of dilated ventricles with gross impairment of ventricular systolic function. However, few reports on perioperative management of DCM were obtainable. This paper describes perioperative management of two patients with DCM. A 72-year-old man, whose DCM had been treated with medication, was planned for gastrectomy. His cardiac signs indicated NYHA class II. Cardiac function, evaluated prior to the surgery with echocardiography to determine an operative indication, turned out to be well compensated. Minimal cardiac derangements were anticipated perioperatively. The procedure was carried out under general anesthesia with neuroleptanalgesia utilizing butorphanol and vasoactive agents. No circulatory complications were observed throughout the surgery. A 66-year-old man, who had long-standing heart disease, hemiplegia and hydronephrosis due to ureteral stone, was planned for percutaneous nephrolithotomy. However, the planned surgery was withdrawn because he had DCM with minimal compensatory function and perioperative cardiac derangements were anticipated according to the categorized data classified with echocardiography. We conclude that preoperative assessment of cardiac function is essential to minimize perioperative cardiac derangements in patients with DCM.
