Due to lack of blood circulation to the brain, a person who survives a cardiac arrest is at risk for neurologic dysfunction ranging from mild to severe. Initiating mild therapeutic hypothermia (MTH) has been implemented in many institutions to improve neurologic outcome for patients who achieve return of spontaneous circulation (ROSC) following cardiac arrest. However, it is not known if MTH is equally effective for shockable and non-shockable rhythms. The purpose of this study is to evaluate research conducted to determine the effectiveness of MTH on shockable and non-shockable rhythms. Four studies were reviewed to determine the appropriateness of MTH after ROSC. Similarities between the studies indicated an increase in good neurologic outcomes following shockable rhythms when MTH was implemented. However, the literature reviewed revealed inconsistent findings to indicate an increase in good neurologic outcomes following ROSC of non-shockable rhythms when MTH was initiated. Further research is needed to establish the effectiveness of MTH following ROSC of non-shockable rhythms.
