Randomized Controlled Trial
Therapeutic hypothermia after cardiac arrest - cerebral perfusion and metabolism during upper and lower threshold normocapnia.
During cardiac arrest and after successful resuscitation a continuum of ischaemia-reperfusion injury develops. Mild hypothermia exerts protective effects in the postresuscitation phase but also alters CO₂ production and solubility, which may lead to deleterious effects if overlooked when adjusting the ventilation of the resuscitated patient. Using a multimodality approach, the effects of different carbaemic states on cerebral perfusion and metabolism were evaluated during therapeutic hypothermia. ⋯ During induced hypothermia, lower threshold normocapnia was associated with decreased cerebral perfusion/oxygenation but not reflected to interstitial metabolites. Upper threshold pCO₂ increased cerebral perfusion and reduced cerebral lactate. Vigilance over the ventilatory and CO₂ analysis regimen is mandatory during mild hypothermia.

Review Case Reports
Out-of-hospital extra-corporeal life support implantation during refractory cardiac arrest in a half-marathon runner.
For patients who present with an out-of-hospital refractory cardiac arrest, in-hospital extracorporeal life-support (ECLS) initiation represents an alternative therapy which allows significant survival. We describe here the first case of out-of-hospital ECLS implantation in a patient presenting with a refractory cardiac arrest during a road race. ⋯ Coronarography revealed a severe isolated stenosis of the right coronary artery, which was treated by angioplasty. The cardiogenic shock resolved progressively, enabling ECLS weaning within 48h, while renal, hepatic, and respiratory functions recovered simultaneously.

Multicenter Study Comparative Study
A comparison of the area of chest compression by the superimposed-thumb and the alongside-thumb techniques for infant cardiopulmonary resuscitation.
We investigated whether the superimposed-thumb technique could reduce the chest compression area in infant cardiopulmonary resuscitation (CPR). ⋯ In this study, we confirmed that the superimposed-thumb technique may reduce chest compression area in infant CPR. The lungs or livers were located more often underneath thumbs alongside at S(nipple) than underneath thumbs superimposed at S(ap). However, further studies are needed to validate the efficiency and safety of this technique.

The inability to accurately predict acute traumatic coagulopathy (ATC) has been a key factor in the low level of evidence guiding its management. The aim of this study was to develop a tool to accurately identify patients with ATC using pre-hospital variables without the use of pathology or radiological testing. ⋯ The COAST score accurately identified a group of patients with ATC using pre-hospital observations. This predictive tool can be used to select patients for inclusion into prospective studies examining management options for ATC. Mortality in these patients is high, potentially improving feasibility of outcome studies.
