Abstract

Objective

Describe the yield of computed tomography brain (CTB) scans in patients intubated for drug overdose.

Methods

Retrospective descriptive study using existing registry data from two Australian EDs between February 2021 and June 2022.

Results

Two hundred and six patients were intubated; 159 (77%) received a post-intubation CTB scan. Of these, 38 out of 159 (24%) had a documented indication (i.e. head injury and seizure) for their scans, with a yield of 5.3% (95% confidence interval [CI] = 1.5–17%). Of the 121 out of 159 (76%) patients without an indication, the yield of CTB was 0% (95% CI = 0–3%).

Conclusions

Routine imaging of patients intubated for overdose without clinical indication is unjustified.

计算机断层扫描脑部扫描在插管用药过量患者中的实用性。

目的描述因用药过量而插管的患者的脑部计算机断层扫描（CTB）结果：利用澳大利亚两家急诊室在 2021 年 2 月至 2022 年 6 月期间的现有登记数据进行回顾性描述研究：26 名患者接受了插管；159 人（77%）接受了插管后 CTB 扫描。其中，159 人中有 38 人（24%）有扫描的记录指征（即头部损伤和癫痫发作），扫描率为 5.3%（95% 置信区间 [CI] = 1.5-17%）。159名患者中有121名（76%）没有适应症，CTB的收益率为0%（95% CI = 0-3%）：结论：在无临床指征的情况下对因用药过量而插管的患者进行常规成像是不合理的。
