Cerebral Oxygen Saturation During Electroconvulsive Therapy: A Secondary Analysis of a Randomized Crossover Trial

Background: Electroconvulsive therapy (ECT) causes acute changes in cerebral perfusion and oxygenation. Near-infrared spectroscopy is a novel, noninvasive technique to assess cerebral oxygen saturation (cSO2). We hypothesized that cSO2 increases during ECT and more so with atropine premedication and decreases when systemic desaturation (peripheral oxygen saturation 60% at any measured time point, even in those with systemic desaturation. Conclusions: ECT increased cSO2 irrespective of atropine premedication. cSO2 was lower when systemic desaturation occurred. Future studies should explore the effect of cerebral oxygenation changes during ECT on outcome of psychiatric conditions.
