The influence of thiopental (Trapanal) on coronary blood flow (MPF), myocardial oxygen consumption (MVO2), and general haemodynamics was investigated in seven patients without heart disease. Besides measurement of MBF, the amount of substrates (glucose, lactate, pyruvate and free fatty acids (FFA) was also determined in arterial and coronary sinus blood samples. Thiopental was given intravenously in a mean dose of 4 mg/kg b,w, MBF was measured by means of the argon method. After injection of thiopental, all seven patients showed a significant increase of MBF and MVO2, a fact which can essentially be explained by the increase of heart rate. The effects of thiopental on arterial concentrations, arterior-coronary substrate differences, myocardial uptake, and O2-extraction ratio of the different substrates are discussed.

Twenty-four patients with severe, 24 with moderate, and 24 without heart disease were selected for measurements of systolic time intervals (STI) and blood pressure before and during anesthesia. In all patients anesthesia was induced with thiopental, 4 mg/kg. After tracheal intubation, 12 patients from each heart-disease class received halothane-N2O-O2 (halothane) and 12 patients from each class morphine-d-tubocurarine-N2O-O2 (MS-dTc). Thiopental increased the pre-ejection period (PEP), decreased left ventricular ejection time (LVET), and accelerated heart rate (HR). These changes were similar in patients with and without heart disease. Halothane and and MS-dTc lowered systolic blood pressure and increased PEP/LVET. With halothane but not with MS-dTc these changes were more pronounced in patients who had heart disease. Changes of the PEP/LVET ratio during halothane anesthesia were a better discriminating variable among patients without, with moderate, and with severe heart disease than were changes in systolic blood pressure.

A 70-year-old man who had been drinking a bottle of whisky each day was scheduled for laser resection of a tongue tumor. His electrocardiogram showed sinus bradycardia (heart rate was 35-40 bpm), and transient complete heart block was observed. Echocardiography showed hypertrophic cardiomyopathy. After a temporary transvenous pacemaker had been inserted, anesthesia was induced with thiopental and vecuronium bromide, and maintained with sevoflurane and fentanyl. Heart rate was 45.min-1 before the induction of anesthesia, and after the induction increased to 70-80.min-1. Analysis of heart rate variability suggested that the increase in heart rate was due to augmentation of sympathetic nervous activity after intubation and operation stress. After the operation his bradycardia improved gradually, and after 3 months heart rate settled at about 55.min-1. Cadiomyopathy is known to be one of the complications of alcoholism. It was reported that alcoholic heart disease was improved promptly by abstinence from alcohol. During his long hospitalization, abstinence might have improved his severe bradycardia. Thiopental is useful for induction of anesthesia in a patient with severe bradycardia from alcoholic cadiomyopathy.
