Resuscitation
-
Successful resuscitation after cardiac arrest is typically associated with cerebral and myocardial ischemia/reperfusion (I/R)-injury. Recently, we have demonstrated effects of therapeutic hypothermia (HT) and postconditioning with the volatile anesthetic sevoflurane (SEV) on I/R-mediated mechanisms in the heart and brain [Meybohm et al., PLoS One, 2009; Meybohm et al., Crit Care, 2010]. As the intestine is also highly susceptible to I/R-injury, we investigated the influence of HT and SEV on intestinal I/R-mediated events induced by cardiac arrest and successful resuscitation. ⋯ HT and postconditioning with SEV influence the expression and activity of several small intestinal proteins that are possibly involved in intestinal I/R-mediated events following successful cardiopulmonary resuscitation.

Randomized Controlled Trial Comparative Study
Comparison of intraosseous versus central venous vascular access in adults under resuscitation in the emergency department with inaccessible peripheral veins.
Current European Resuscitation Council (ERC) guidelines recommend intraosseous (IO) vascular access, if intravenous (IV) access is not readily available. Because central venous catheterisation (CVC) is an established alternative for in-hospital resuscitation, we compared IO access versus landmark-based CVC in adults with difficult peripheral veins. ⋯ IO vascular access is a reliable bridging method to gain vascular access for in-hospital adult patients under resuscitation with difficult peripheral veins. Moreover, IO access is more efficacious with a higher success rate on first attempt and a lower procedure time compared to landmark-based CVC.

Review Meta Analysis
Vasopressin for cardiac arrest: meta-analysis of randomized controlled trials.
Prior meta-analyses-reported results of randomised controlled trials (RCTs) published between 1997 and 2004 failed to show any vasopressin-related benefit in cardiac arrest. Based on new RCT-data and a hypothesis of a potentially increased vasoconstricting efficacy of vasopressin, we sought to determine whether the cumulative, current evidence supports or refutes an overall and/or selective benefit for vasopressin regarding sustained restoration of spontaneous circulation (ROSC), long-term survival, and neurological outcome. ⋯ Vasopressin use in the resuscitation of cardiac arrest patients is not associated with any overall benefit or harm. However, vasopressin may improve the long-term survival of asystolic patients, especially when average T(DRUG) is <20 min.

Randomized Controlled Trial Multicenter Study Comparative Study
Predicting non-cardiac aetiology: a strategy to allocate rescue breathing during bystander CPR.
Optimal care for out-of hospital cardiac arrest (OHCA) patients may depend on the underlying aetiology of OHCA. Specifically chest compression only bystander CPR may provide greater benefit among those with cardiac aetiology and chest compressions plus rescue breathing may provide greater benefit among those with non-cardiac aetiology. The aim of this study was to generate a simple predictor model to identify OHCA patients with non-cardiac aetiology in order to accurately allocate rescue breathing. ⋯ The results highlight the challenge of accurately identifying non-cardiac aetiology by characteristics that could be consistently used to allocate bystander rescue breathing.
