Therapeutic Hypothermia (also called targeted temperature management (TTM)) is a deliberate reduction of the core body temperature to 32 - 34°C, in patients who suffer cardiac arrest with return of spontaneous circulation, but also don't regain consciousness.  In REBEL Crit Cast episode 1, I will go through the evidence for cooling adults and children, potential adverse effects, and what temperature to shoot for.

Background: In 2002, the New England Journal of Medicine published two studies that changed the management of post-cardiac arrest patients by showing improved outcomes in patients treated with therapeutic hypothermia (32°C-34°C) for at least 24 hours. (Bernard 2002, Hypothermia 2002).  The landscape changed again in 2013 with the publication of the Targeted Temperature Management (TTM) trial in the New England Journal, which compared post-cardiac arrest hypothermia at 32-34°C and at 36°C and found no difference in outcomes (Nielson 2013). After the publication of the TTM trial, many hospitals changed their cooling protocols to a target temperature of 36°C, however, recently it has been shown that this may pose an increased risk of fever. (Cassamento 2016).

The use of therapeutic hypothermia (TH) has become part of the routine care of patients after return of spontaneous circulation (ROSC) from cardiac arrest (Use of the phrase Targeted Temperature Management has become more accepted). It became much more accepted after two separate trials were published in the New England Journal of Medicine in 2002 showing a survival benefit and improved neurologic outcome with use of TH. (1,2) The use of TH has even been given a Level One recommendation by the American Heart Association for comatose post-arrest patients. (3) Uncertainties still remain, however, such as what optimal temperature to use, and most recommendations on specifics related to TH are based on observational studies and expert opinion. So what is the actual evidence behind the use of TH?
