The study aimed at comparing the fixed tapering dose and the symptom-triggered regimens of lorazepam for alcohol detoxification.
We carried out a prospective, randomized, double blind controlled trial involving 63 consecutive consenting male patients admitted with diagnosis of uncomplicated alcohol withdrawal. The patients were randomized into two groups based on the type of lorazepam dosage: symptom-triggered (n = 33) and fixed tapering dose regimens (n = 30). Alcohol withdrawal symptoms were rated on CIWA-Ar (Clinical Institute Withdrawal Assessment - Alcohol revised). The main outcome measures were the total amount and duration of lorazepam treatment and the incidence of adverse events or complications.
The mean lorazepam dose administered in the symptom-triggered group was significantly lower than in the fixed tapering dose group (9.5 versus 19.9 mg, P < 0.001) and for a significantly shorter duration of time (47.8 versus 146 h, P < 0.001) with more significant results for higher initial CIWA-Ar scores. There were no significant differences between both the groups in terms of the incidence of complications like seizures or delirium tremens.
Symptom-triggered lorazepam treatment for alcohol withdrawal resulted in administration of lower total doses of medication for a shorter duration of treatment and was as safe as the fixed tapering dose.
本研究旨在比较氯硝西泮固定递减剂量方案和症状触发方案用于酒精戒断治疗的效果。
我们进行了一项前瞻性、随机、双盲对照试验,纳入63例连续同意参与的男性患者,这些患者因单纯酒精戒断入院。根据氯硝西泮剂量类型将患者随机分为两组:症状触发组(n = 33)和固定递减剂量组(n = 30)。采用CIWA-Ar(临床研究所酒精戒断评估修订版)对酒精戒断症状进行评分。主要观察指标为氯硝西泮治疗的总量、持续时间以及不良事件或并发症的发生率。
症状触发组的氯硝西泮平均给药剂量显著低于固定递减剂量组(9.5 mg对19.9 mg,P < 0.001),且给药持续时间显著更短(47.8小时对146小时,P < 0.001),初始CIWA-Ar评分越高,结果越显著。两组在癫痫发作或震颤谵妄等并发症发生率方面无显著差异。
症状触发的氯硝西泮治疗酒精戒断可在更短的治疗时间内给予更低的药物总剂量,且与固定递减剂量方案同样安全。
