TTM2 - Therapeutic Hypothermia after Cardiac Arrest * Population: adult patients with out of hospital cardiac arrest who were comatose * Intervention: cooled to 33°C vs. maintaining normothermia * Primary Outcome: all-cause mortality at 6 months * Results: no statistical difference between groups (~50% in both groups) Bottom line: no benefit to cooling patients after out of hospital cardiac arrest who are comatose Deep dive: https://thesgem.com/2021/07/sgem336-you-cant-always-get-what-you-want-ttm2-trial/ Deep dive into worlds literature on therapeutic hypothermia: Journal Jam on Therapeutic Hypothermia after Cardiac Arrest 2.
