Brief Summary:

Postresuscitation disease is a constellation of disorders related to whole-body ischemia and reperfusion syndrome. It includes hypoxic damage in brain, liver, kidney, heart and other organ. In previous study more than one-third of patients resuscitation from out of hospital cardiac arrest developed renal dysfunction. In acute kidney injury, NGAL is an earlier marker compared with serum creatinine.

Cardiac arrest and severe asphyxia result in global brain ischemia. In previous study serum NGAL correlated with hypoxic ischemic encephalopathy in asphyxiated neonate.

This study was designed to assess serum NGAL level in postresuscitative patients to evaluate its relation to hypoxic brain injury severity, and its clinical utility for early detection of acute kidney injury in these patients.

Group/Cohort Intervention/treatment
Post cardiac arrest patient Biological: Serum NGAL level
Investigators will check the plasma NGAL level after 4 hour from resuscitation. The plasma NGAL level is measured in ng/mg

Primary Outcome Measures :
  1. Predictive value of plasma NGAL for acute kidney injury and cerebral dysfunction following out of hospital cardiac arrest. [ Time Frame: Every 4 hour until 72 hour after resuscitation ]

    All patients in this study will be treated by induced hypothermia protocol in our hospital. Plasma NGAL level will check after 4hour from resuscitation. Renal dysfunction is defined using the RIFLE criteria. Patient base line creatinine is defined the first laboratory values obtained in the emergency department. The maximum difference between the peak creatinine level during the first 72hour of hospitalization and the base line creatinine level was determined for every patients.

    Cerebral dysfunction is defined using CPC scale. Neurologic exam will be performed on arrival, 24, 48,72 hours after resuscitation and discharge day. Good neurologic outcome is defined as CPC of 1 or 2. The diagnostic accuracy of NGAL in predicting acute kidney injury and neurologic outcome will be evaluated.
