Right unilateral brief pulse (RUL-BP) electroconvulsive therapy (ECT) has been adopted as a technique for reducing the cognitive side effects of ECT relative to sine wave or bilateral treatments, but it is unknown how often patients are transitioned to alternative electrode placements. This study analyzes time in first lifetime acute course RUL-BP ECT.
A single-center retrospective chart review was conducted of adult patients receiving a first lifetime course of ECT from 2000 to 2017 beginning with individualized seizure threshold determination using RUL-BP treatment parameters.
A total of 1383 patients met study criteria and received a mean number of 9.4 ± 3.1 treatments, of which 7.6 ± 3.3 were using RUL-BP stimuli. Only 37.5% of patients were transitioned from RUL to bilateral treatments. Younger patients and those diagnosed with bipolar disorder were more likely to transition from RUL-BP to bilateral treatments, but the overall number of treatments did not differ based on age or primary diagnosis.
Among patients who begin treatment with RUL-BP ECT, more than 60% use exclusively those parameters throughout their acute course.
与正弦波或双侧治疗相比，右侧单侧短暂脉冲（RUL-BP）电惊厥疗法（ECT）已被采用为减少 ECT 认知副作用的技术，但尚不清楚患者转换为替代电极放置的频率。本研究分析了首次急性 RUL-BP ECT 疗程中的时间。
对 2000 年至 2017 年期间在单个中心接受首次终身 ECT 治疗的成年患者进行了回顾性图表审查，该治疗使用 RUL-BP 治疗参数开始个体化癫痫发作阈值测定。
共有 1383 名患者符合研究标准，平均接受 9.4±3.1 次治疗，其中 7.6±3.3 次使用 RUL-BP 刺激。只有 37.5%的患者从 RUL 转为双侧治疗。年轻患者和诊断为双相情感障碍的患者更有可能从 RUL-BP 转为双侧治疗，但基于年龄或主要诊断，治疗次数没有差异。
在开始 RUL-BP ECT 治疗的患者中，超过 60%的患者在整个急性疗程中仅使用这些参数。
