BACKGROUND
The aim of this study was to determine the prognostic value and optimal sampling time of serum S-100B protein for the prediction of poor neurological outcomes in post-cardiac arrest (CA) patients treated with therapeutic hypothermia (TH).
METHODS
We prospectively measured serum S100 calcium binding protein beta subunit (S-100B protein) levels 12 times (0-96 hours) after the return of spontaneous circulation (ROSC). The patients were classified into two groups based on cerebral performance category (CPC): the good neurological outcome group (CPC 1-2 at 6 months) and the poor neurological outcome group (CPC 3-5). We compared serial changes and serum S-100B protein levels at each time point between the two groups and performed receiver operating characteristic curve analysis for the prediction of poor neurological outcomes.
RESULTS
A total of 40 patients were enrolled in the study. S-100B protein levels peaked at ROSC (0 hour), decreased rapidly to 6 hours and maintained a similar level thereafter. Serum S-100B protein levels in the poor CPC group (n = 22) were significantly higher than in the good CPC group (n = 18) at all time points after ROSC except at 4 hours. The time points with highest area under curve were 24 (0.829) and 36 (0.837) hours. The cut-off value, the sensitivity (24/36 hours) and specificity (24/36 hours) for the prediction of poor CPC at 24 and 48 hours were 0.221/0.249 ug/L, 75/65% and 82.4/94.1%, respectively.
CONCLUSIONS
Serum S-100B protein was an early and useful marker for the prediction of poor neurological outcomes in post-CA patients treated with TH and the optimal sampling times were 24 and 36 hours after ROSC.

BACKGROUND
Cardiac arrest in infants and children is rare than adults yet, it is critical. The efficacy and feasibility of therapeutic hypothermia after cardiac arrest in adults is proved through many studies however, there are few data on pediatric out-of hospital cardiac arrest. We analyzed several variables in pediatric therapeutic hypothermia after out-of hospital cardiac arrest.
METHODS
Infants and children (1 to 17 years old), who were admitted to our emergency intensive care units following the return of spontaneous circulation after out-of hospital cardiac arrest from Jan 2008 to Apr 2012, were included in this study. Basal patients' characteristics and variables about therapeutic hypothermia were analyzed.
RESULTS
A total of seventy-six patients visited our emergency center after a pediatric cardiac arrest during the study period. Among this, sixty-three patients received pediatric advanced life support, twenty one patients were admitted to intensive care units and nine patients received therapeutic hypothermia. Overall, the survival discharge was 7.9% (5 of 63). Among the admitted patients, 3 patients (14.3%) had a good Cerebral Performance Category (CPC). Two patients received endovascular cooling and seven patients received surface cooling. The mean time from the induction of therapeutic hypothermia to reaching the temperature with in the therapeutic range was 193.9 minutes. There were no critical adverse events during induction, maintenance and the rewarming period of therapeutic hypothermia.
CONCLUSIONS
Therapeutic hypothermia after pediatric out-of hospital cardiac arrest was performed safely and effectively in one emergency center. The standardized pediatric therapeutic hypothermia protocol should be established in order to be used widely in pediatric intensive care units. Further, larger studies are needed on the subject of pediatric therapeutic hypothermia.

AbstractAbstract PDF
BACKGROUND
Early defibrillation is the treatment of choice in out-of-hospital cardiac arrests (OHCA) with initial shockable rhythms. However, the relationship between the frequency of defibrillation and neurological outcome was not clear. In this study, the frequency of defibrillation and other factors related to neurological outcome were investigated.
METHODS
Records of 255 adult patients, who were admitted to the hospital after resuscitation from OHCA between November 2008 and March 2012, were retrospectively reviewed. 6 months after the return of spontaneous circulation, patients were divided into two groups based on the cerebral performance category (CPC) score for neurologic prognosis. The frequency of defibrillation during resuscitation and other variables were analyzed between the two groups.
RESULTS
In the study group, initial rhythm was divided into two groups, non shockable rhythm (200, 78.4%) and shockable rhythm (55, 21.6%). The frequency of 1-7 defibrillations was significantly associated with good neurological outcome (OR 3.05, 95% CI 1.328-6.850). In addition, shockable initial rhythm (OR 4.520, 95% CI 1.953-10.459), arrest caused cardiac origin (OR 2.945, 95% CI 1.334-6.500), time to BLS (OR 1.139, 95% CI 1.033-1.256) and lower APACHII score (OR 1.095, 95% CI 1.026-1.169), which were associated with good neurological outcomes, independently.
CONCLUSIONS
In those patients who survived from OHCA, adequate defibrillation was important to improve the neurological outcome, whether the initial rhythm was shockable or not. Frequency of 1-7 times defibrillation was associated with good neurological outcome.
