Resuscitation

Hemorrhagic shock is associated with severe rheological abnormalities. We hypothesized that in the setting of hemorrhagic shock, resuscitation can alter hemorheological characteristics dramatically, and different fluids cause different effects. The aim of this study was to investigate whether the type of fluid administered has an impact on hemorheological characteristics at the early stage of resuscitation in a rodent model of hemorrhagic shock. ⋯ These results suggested that at the early stage of hemorrhagic shock resuscitation, hypertonic-hyperoncotic resuscitation could improve RBC deformability compared with isotonic crystalloid resuscitation. Dextran 70 could elevate plasma viscosity to nearly baseline level. These effects of hypertonic-hyperoncotic resuscitation could be beneficial to maintain microcirculation.

Multicenter Study Clinical Trial
Chest compression quality variables influencing the temporal development of ROSC-predictors calculated from the ECG during VF.
Predictive measures that reflect the probability of return of spontaneous circulation (ROSC) if the patient is defibrillated can be calculated from the electrocardiogram during ventricular fibrillation (VF) and ventricular tachycardia (VT). It has not been studied how the quality of chest compressions affect the development of such ROSC predictors. ⋯ Using MS as an indicator of the state of the myocardium, force-based compression quality variables are better indicators of efficient CPR than compression depth. A novel indicator termed residual heart force gives the best correlation with observed trends in MS.

Randomized Controlled Trial
Predictive power of serum NSE and OHCA score regarding 6-month neurologic outcome after out-of-hospital ventricular fibrillation and therapeutic hypothermia.
To determine the predictive power of the out-of-hospital cardiac arrest (OHCA) score and serum neuron-specific enolase (NSE) in patients resuscitated from ventricular fibrillation treated with therapeutic hypothermia (TH) and glucose control. ⋯ Increase in NSE between 24 and 48h and NSE at 48h is specific but only moderately sensitive markers of 6-month outcome. Outcome prediction at ICU admission using the OHCA score was not possible in this selected patient population.
