Ventilation strategies used during anaesthesia for electroconvulsive therapy: scoping review protocol.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundElectroconvulsive therapy (ECT) is an established treatment for depression and mania, with its therapeutic effect deriving from the induced seizure rather than the electrical stimulus itself. Anaesthetic agents are routinely used to reduce procedural discomfort, requiring assisted ventilation. However, these agents may raise the seizure threshold, necessitating higher stimulus doses and potentially increasing adverse effects. Although various strategies have been explored, pre-ECT hyperventilation-despite its known ability to lower the seizure threshold-remains insufficiently investigated. This review aims to examine the various ventilation approaches employed during anaesthesia for ECT, assess how hyperventilation has been applied to augment ECT, explore their impact on clinical outcomes and identify the outcome parameters most frequently investigated in ECT studies.
methodsThe reporting of the scoping review will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. A comprehensive literature search will be conducted in Medline, EMBASE, Scopus and PsycINFO. Grey literature, along with national and international guidelines, will also be included. Studies investigating any form of ventilation during anaesthesia for ECT will be included. An information specialist and a medical librarian will support the development and refinement of the search strategy. Two reviewers will independently screen eligible studies and perform data extraction according to predefined headings. Disagreements will be resolved by a third reviewer. Data will be organised under the following headings: details of the included studies, ventilation strategies investigated, outcome measures studied. Results will be presented narratively and in table form and discussed in relation to the relevant literature. ETHICS AND DISSEMINATION: Ethical approval is not necessary, as the review synthesises evidence from the existing literature. The results will be disseminated through publication in a peer-reviewed journal and presentation at relevant academic conferences. Findings will also be shared with ECT clinicians to support clinical awareness and inform practice.
