Clinical Trial Summary

The purpose of this study is to determine whether targeted temperature management at 36.0˚C(TTM-36) in patients who remain unconscious after resuscitation from in-hospital cardiac arrest(IHCA) will reduce death and disability compared with fever control. For this purpose, the current pilot study will be undertaken to establish the feasibility, safety, and surrogate outcomes of hypoxic-ischemic brain injury in 60 patients who remain unconscious after resuscitation from IHCA.

Eligible patients will be randomly assigned in a 2:1 ratio to either TTM-36(n=40) or conventional treatment group(n=20). Randomization will be performed with stratification according to initial rhythm (shockable vs. non-shockable).

Outcome

Type Measure Description Time frame Safety issue
Other Safety of the targeted temperature management at 36.0?(TTM-36) Safety will be assessed by the composite measurement below everyday during the first 7 days after cardiac arrest.

Pneumonia(pulmonary infiltration on the chest radiography and 2 or more of fever, leukocytosis, and purulent tracheobronchial secretions)
Septic shock(sepsis-induced hypotension persisting despite adequate fluid resuscitation)
