| Abstract | 「Abstract」The relationship between changes in hemodynamics and the digital skin blood flow (DBF) was investigated by laser Doppler flowmetry during electroconvulsive therapy (ECT) under propofol anesthesia. Under anesthesia with propofol and succinylcholine, ECT lasting for 5 sec was induced in 7 patients with depression. They were monitored by continuos ECG and pulse oxymetry, intermittent blood pressure, using an automatic blood pressure apparatus. The DBF of the first finger was also continuously measured with laser Doppler flowmetry. ECT caused a marked elevation in systolic and diastolic blood pressures and a significant reduction in the DBF. The DBF was restored within several minutes after ECT. There was a statistically significant linear correlation between the increase in systolic or diastolic blood pressure and the decrease in the DBF (r=0.62, p<0.001), but no linear correlation between the changes in heart rate and the DBF. It was concluded that those changes were due to a sympathetic response to ECT. Our results indicate that the DBF reflects sympathetic nervous activity during ECT under propofol anesthesia. |
