Recent literature on electroconvulsive therapy (ECT) emphasizes the use of moderately suprathreshold electrical stimuli for clinical ECT. Since there is substantial interpatient variability in seizure thresholds, individualization of the ECT stimulus dose has been advocated. Three methods for selecting an electrical stimulus are compared in the present study. The methods compared include empirical titration and dose predictive methods described by two different ECT equipment instruction manuals. The use of ECT stimulus titration was found to be a more consistent means of selecting an electrical dose than either of the two predictive methods. The implications of these findings for the clinical practice of ECT are discussed.
近期关于电休克治疗（ECT）的文献强调在临床ECT中使用适度高于阈值的电刺激。由于癫痫发作阈值在患者之间存在很大差异，因此提倡对ECT刺激剂量进行个体化。本研究比较了三种选择电刺激的方法。所比较的方法包括两种不同ECT设备使用说明书中描述的经验滴定法和剂量预测法。结果发现，与两种预测方法中的任何一种相比，ECT刺激滴定法是选择电剂量更一致的方法。本文讨论了这些发现对ECT临床实践的意义。
