Acute cardiac care & resuscitation
Association of pre-hospital tracheal intubation with outcomes after out-of-hospital cardiac arrest by drowning comparing to supraglottic airway device: A nationwide propensity score-matched cohort study
Authors' conclusion
In this propensity score-matched study of adult OHCA by drowning, ETI compared to SGA was associated with ROSC but not associated with survival and favourable neurological outcomes at one month.
Study context
