Review Meta Analysis
Therapeutic hypothermia and prevention of acute kidney injury: a meta-analysis of randomized controlled trials.
Therapeutic hypothermia has been shown to reduce neurological morbidity and mortality in the setting of out-of-hospital cardiac arrest and may be beneficial following brain injury and cardiopulmonary bypass. We conducted a systematic review to ascertain the effect of therapeutic hypothermia on development of acute kidney injury (AKI) and mortality. ⋯ In trials that ascertained kidney endpoints, therapeutic hypothermia prevented neither the development of AKI nor dialysis requirement, but was associated with lower mortality. Different definitions and rates of AKI, differences in mortality rates, and concerns about the optimal target cooling temperature preclude definitive conclusions.

The benefit of therapeutic hypothermia (TH) for comatose adult patients with return of spontaneous circulation after cardiac arrest (CA) with non-shockable initial rhythms is uncertain. We evaluated whether TH reduces mortality and improves neurological outcome in comatose adults resuscitated from non-shockable CA. ⋯ TH is associated with reduced in-hospital mortality for adults patients resuscitated from non-shockable CA. However, most of the studies had substantial risks of bias and quality of evidence was very low. Further high quality randomized clinical trials would confirm the actual benefit of TH in this population.
