A Slow Retreat
Given the recent large trials showing no clear benefit of TTM over normothermia, consider critically reassessing the routine application of cooling protocols in your post-arrest patients. While guidelines remain standard, these data suggest we may be managing based on outdated or weak evidence; always maintain a high index of suspicion for alternative etiologies rather than defaulting to temperature control.
This piece raises significant questions about the foundational premise of targeted temperature management (TTM) following cardiac arrest, suggesting that much of its initial evidence was derived from small and methodologically questionable trials. The authors point to more recent large-scale studies, including those involving TTM and Kirkegaard et al., which have failed to demonstrate any discernible difference in patient outcomes when comparing controlled cooling against standard normothermia protocols. This suggests that the current guidelines supporting TTM might be resting on an increasingly tenuous evidentiary base that warrants serious re-evaluation by the community.
