An emergency-airway cohort associated ketamine with less post-intubation hypotension than a combined reference group.
The analysis included 977 hemodynamically unstable adult patients. Hypotension occurred in 15% of ketamine recipients and 29% of those receiving midazolam or propofol, with an association persisting after adjustment and matching. The outcome concerned the immediate post-intubation period.
The result cannot assign the whole difference specifically to midazolam, because the comparator included another sedative. Observational treatment choice, fluid and vasopressor management, and other clinical differences leave residual confounding. The study also lacked later hospital outcomes. It supports attention to hemodynamic context during induction, but not a claim that ketamine is always safer or that midazolam caused an individual episode. The exact drug, dose, baseline physiology, and sequence remain essential.
