Ice-Cold Crystalloid for Therapeutic Hypothermia
- Therapeutic hypothermia (TH) is a critical component in the care of patients with ROSC from out-of-hospital cardiac arrest.
- Despite recent guidelines, initiation of TH in the ED for appropriate patients remains less than optimal.
- Reported barriers to the induction of TH in the ED include lack of familiarity, lack of collaboration with the ICU, access to special equipment, and the logistics of cooling.
- A recent analysis of studies on the use of ice-cold crystalloids (ICC) found that an infusion of 40 C fluid is a safe, effective, inexpensive, and readily available method for inducing TH.
- Importantly, no study reported any significant hemodynamic complication (i.e. CHF) from the use of ICC.
- Lastly, once the target temperature has been reached, ICC alone cannot maintain TH. Additional methods, such as surface cooling blankets or ice packs, should be used.
