The impact of ketamine on emergency rapid sequence intubation: a systematic review and meta-analysis.
Synthesis in BMC emergency medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
backgroundRapid sequence intubation (RSI) is a crucial step in the resuscitation process for critically ill patients, and the judicious use of sedative drugs during RSI significantly influences the clinical outcomes of patients. Ketamine is a commonly used anesthetic sedative; however, its impact on the mortality of patients undergoing RSI has yielded inconsistent findings. Therefore, we conducted a systematic review and meta-analysis investigating ketamine's role in RSI to provide insights into selecting appropriate sedatives for critically ill patients.
methodsIn this systematic review and meta-analysis, we conducted a systematic search on MEDLINE (PubMed), Embase, and Cochrane Central Register of Controlled Trials, without restricting to randomized controlled trials (RCTs) or cohort studies. The search was performed from inception until Dec 12, 2023, with no language restrictions. All studies comparing the use of sedatives, including ketamine, and documenting in-hospital mortality were included in this study.
resultsA total of 991 studies were identified, out of which 15 studies (5 RCTs and 10 cohort studies) involving 16,807 participants fulfilled the inclusion criteria. No significant impact on in-hospital mortality was observed with the use of ketamine compared to other drugs during RSI (OR 0.90, 95%CI 0.72 to 1.12). Low-quality evidence suggested that ketamine might reduce mortality within the first seven days of hospitalization (OR 0.42, 95%CI 0.19 to 0.93), but it may also have a potential effect on prolonging ICU-free days at day 28 (MD -0.71, 95%CI -1.38 to -0.05). There were no significant differences in the results of the other RSI-related outcomes, such as physiological function and adverse events.
conclusionsBased on existing studies, ketamine showed no significant difference compared to other sedatives in terms of in-hospital mortality, physiological impact, and side effects following RSI. However, it may reduce mortality within 7 days while probably prolong the length of stay in the ICU.
