Guidelines recommend selecting and maintaining a constant target #TTM between 32 and 36 °C in comatose post-cardiac arrest patients to prevent hypoxic-ischemic brain damage.
(strong recommendation, moderate-quality evidence). #FOAMcc
Two RCTs published in 2002 showed an improved survival and neurologic outcome in patients resuscitated from OHCA of presumed cardiac cause and shockable rhythm who underwent hypothermia at 33°C. #FOAMcc
In 2019, @JBLascarrou and colleagues published the #HYPERIONtrial showing that 24h #TTM 33°C vs. targeted normothermia (37°C) improves 90-days neuro outcomes in patients with coma resuscitated from cardiac arrest with nonshockable rhythm. #FOAMcc
RCTs comparing the level of targeted temperature management (#TTM trial, 33°C or 36°C) and the duration of this management (24 hours or 48 hours) have not indicated a dose effect. #FOAMcc
In the just published #TTM2 trial, there was no significant difference between hypothermia and normothermia with respect to death and poor functional outcome at 6 mo.
🫀👀 Looking into the heart of the problem of refractory cardiac arrest
How coronary occlusion severity impacts the responsiveness of OHCA patients to resuscitation is a growing area of interest, fueled in these years by the use of ECPR that allowed previously unrecoverable patients to survive
Although the high frequency of CAD in OHCAs is well known and numerous studies were published, use and findings of CAG are variable and often described only in some subgroups of patients
Type/frequency of coronary lesions in OHCA pts were not summarized before
