To assess differences in cerebral performance category (CPC) in patients who received therapeutic hypothermia post cardiac arrest by time to initiation, time to target temperature, and duration of therapeutic hypothermia (TH). ⋯ In adults undergoing TH post cardiac arrest, delay in initiation of TH and reaching target temperature differentiated poor versus good neurologic outcomes. Randomized trials assessing the range of current recommended guidelines for TH should be conducted to establish optimal treatment protocols.

Randomized Controlled Trial
A randomized trial of compression first or analyze first strategies in patients with out-of-hospital cardiac arrest: results from an Asian community.
It is still under debate whether a period of cardiopulmonary resuscitation should be performed prior to rhythm analysis for defibrillation for out of hospital cardiac arrests (OHCA). This study compared outcomes of OHCA treated by "compression first" (CF) versus "analyze first" (AF) strategies in an Asian community with low rates of shockable rhythms. ⋯ In this study population of low rates of shockable rhythms, there was no difference in ROSC for CF or AF strategies. Considering the EMS operation situations, a period of paramedic-administered CPR for up to 10 cycles prior to rhythm analysis could be a feasible strategy in this community.

Therapeutic hypothermia (TH) has revolutionized the management of comatose post-cardiac arrest syndrome (PCAS) patients. The 2008 ILCOR/AHA Consensus Statement for the treatment of PCAS suggests that goal-directed therapy, targeting mean arterial pressure (MAP), central venous pressure (CVP), and central venous oxygen saturation (ScvO(2)), should be employed to normalize oxygen delivery. However, the optimal PCAS haemodynamic management strategy has not been defined and few objective data exist to guide clinicians. ⋯ Specific haemodynamic goals are defined in a minority of published TH implementation studies. Given the volatile haemodynamics of the PCAS and lack of consensus on an optimal resuscitation strategy, explicit description of haemodynamic goals should be provided in future studies.
