Protective effect of flumazenil infusion in severe acute benzodiazepine toxicity: a pilot randomized trial.
Trial report in European journal of clinical pharmacology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers, 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
objectiveWe aimed to investigate the efficacy of flumazenil infusion in the maintenance of arousal and prevention of development of complications in severe benzodiazepine poisoning. MATERIALS AND
methodSixty severely poisoned patients (intubated due to loss of consciousness) intoxicated by sole benzodiazepines referred to Loghman Hakim hospital between May 2018 and August 2019 were considered to be included in the current study. All were evaluated for possible contraindications of flumazenil administration. If there were no contraindications, we continued supportive care in one group and supportive care plus flumazenil infusion in the second group. Following response to the stat dose of flumazenil, complications, hospital stay, and outcome were compared between these two groups.
resultsA total of 60 benzodiazepine-poisoned patients aged between 16 and 84 years old (37 males and 23 females) were enrolled. There was no statistically significant difference between these two groups regarding the period of hospital stay. Need for intubation significantly decreased in the infusion group. None of the patients experienced seizure or dysrhythmia. One patient died in the control group which received only a stat dose of flumazenil.
conclusionsAdministration of flumazenil is safe in benzodiazepine-poisoned patients with appropriate indications. Flumazenil infusion can significantly decrease the need for intubation and subsequent ICU admission. Even though flumazenil is an expensive antidote, its administration may decrease the need for ICU beds in the setting of acute poisoning.
