Multicenter Study Comparative Study
Development of a data dictionary for the Strategies for Post Arrest Resuscitation Care (SPARC) network for post cardiac arrest research.
The widely accepted Utstein style has standardized data collection and analysis in resuscitation and post resuscitation research. However, collection of many of these variables poses significant practical challenges. In addition, several important variables in post resuscitation research are missing. ⋯ This is the first attempt in the literature to develop a data dictionary as part of a standardized, pragmatic data collection tool for post cardiac arrest research patients. In addition, our dataset defined important variables that were previously missing. This data collection tool can serve as a reference for future trials in post cardiac arrest care.

Comparative Study
How accurately can the aetiology of cardiac arrest be established in an out-of-hospital setting? Analysis by "concordance in diagnosis crosscheck tables".
Several previous studies have focused on establishing the cause of cardiac arrest (CA) during cardiopulmonary resuscitation (CPR) provided in an out-of-hospital setting. ⋯ This study demonstrates the importance of analysing concordance in presumed and definitive diagnosis of individual cases, since an overall comparison in a cohort of cases may be highly misleading. It introduces the method of the crosscheck table for visualization and comparison of presumed and final diagnoses. The two alternative approaches of inclusion rule for applying the thrombolytic therapy in out-of-hospital care were discussed with regard to the recent TROICA study.

Randomized Controlled Trial Comparative Study
A comparison of paediatric airway anatomy with the SimBaby high-fidelity patient simulator.
The SimBaby high-fidelity patient simulator is a widely used paediatric simulator for the training of standard and critical airway management scenarios. Furthermore this simulator is frequently used for the evaluation of different airway devices and techniques. However, the anatomic structures of the SimBaby have not been compared to actual patients' anatomy. ⋯ The anatomic features of the SimBaby do not adequately simulate the upper airway anatomy of infants. These results imply inadequate realism of this simulator for airway training and compromise the validity of comparative trials of different airway devices with the SimBaby as airway model.

Comparative Study
Outcome of very-low-birth-weight infants who received epinephrine in the delivery room.
In recent years, there has been an increase in the number of very low birth weight (VLBW) infants and an improvement in their survival. However, there are no specific recommendations regarding the use of resuscitative efforts for VLBW infants, and there is scant data in the literature on morbidity and mortality in relation to epinephrine administration. Due to the vulnerability of VLBW infants, studies that examine the effects and consequences of cardiovascular resuscitation and epinephrine administration are needed. ⋯ VLBW infants, who require epinephrine in the delivery room, are smaller in terms of gestational age and birth weight. The requirement of epinephrine in the delivery room during resuscitation may be associated to worst outcomes and decreased survival without severe brain injury. These findings lead to more questions on how aggressive resuscitation efforts should be for these infants.

Hyperoxic ventilation improves survival in pigs during endotoxaemia at the critical hemoglobin concentration.
Recently it has been demonstrated that short term hyperoxic ventilation (HV) can improve glucose metabolism, reduce pulmonary and hepatic apoptosis, and improve gastrointestinal perfusion during acute sepsis. However, it is unknown whether additional O(2) improves survival. Therefore we investigated the effects of increased plasma O(2) on survival during extreme anaemia and concomitant endotoxaemia in order to quantify the efficacy of HV. ⋯ The improvement of survival, oxygen transport and tissue oxygenation seems to underline the efficacy of HV during endotoxaemia and concomitant acute anaemia. Further studies are needed to transfer these results into daily clinical practice.
