Neurocritical care management to improve neurologic outcome for postcardiac arrest syndrome (PCAS) has focused considerably on targeted temperature management (TTM). TTM attenuates the destructive processes following ischemia/reperfusion in PCAS. The principal indication of TTM is a patient with sustained coma after return of spontaneous circulation (ROSC). TTM can be strongly recommended with a target temperature between 32°C and 36°C for patients with shockable rhythm and out-of-hospital cardiac arrest (OHCA) and weakly recommended for patients with initial asystole or pulseless electrical activity with OHCA and those with in-hospital cardiac arrest. TTM is induced and maintained using a cooling device with body temperature feedback under appropriate analgosedation. It requires the intensive management of various systemic respiratory, circulatory, and metabolic parameters that control shivering to prevent secondary brain damage. Considering the cerebral perfusion pressure, it is suggested that the mean arterial pressure should be particularly maintained over 80 mm Hg. Seizure management, including continuous electroencephalography monitoring, is also needed. Finally, we must continue the above mentioned care during and after the rewarming phase, because high fever and shivering may appear again during this period. Furthermore, neurological prognostication should be performed at least 72 hours after ROSC through clinical investigations and multimodal testing without sedation.
