Evaluating Ketamine Dosing Practices During Emergency Department Intubation Using Shock Index Stratification.

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
Background The accurate dosing of ketamine during rapid sequence intubation in emergency settings is critical, especially in patients with varying hemodynamic states. This study describes ketamine dosing practices during rapid sequence intubation in a tertiary emergency department, focusing on concordance with predefined dosing ranges based on shock index. The primary goal is to analyze registry data to assess concordance with recommended weight-based dosing ranges, considering shock index and shock dosing. Methods We analyzed intubation data from the Emergency Medicine - Airway Registry (EM-AWARE) from 2015 to 2021. We included adult patients aged 18 years and above who underwent intubation with ketamine as the sole sedative agent, and stratified patients into two groups: those with a normal shock index below 0.9 and those with an abnormal shock index at or above 0.9. Data were analyzed to determine the proportion of patients who received ketamine doses within, below, or above predefined dosing ranges, and results were compared across the two groups. Results Forty-six patients met the inclusion criteria. There were 29 patients in the normal shock index group, and among these patients, 72% (n = 21) received a dose within the predefined range, and 28% (n = 8) received doses below the range. There were 17 patients in the abnormal shock index group, with 76% (n = 13) receiving a reduced dose within the predefined range and 24% (n = 4) receiving doses outside the range, primarily above the recommended shock dosing range. Overall rates of dosing outside predefined ranges were similar between groups, ranging from 24% to 28%. Conclusion In this single-centre registry analysis, approximately one-quarter of emergency department patients received ketamine doses outside predefined ranges during intubation, regardless of shock index. These findings highlight persistent variability in ketamine dosing practices during emergency airway management.
