Evidence suggests that any interruptions, including those of rescue breaths, during cardiopulmonary resuscitation (CPR) have significant, detrimental effects on survival. The 2010 International Liaison Committee on Resuscitation guidelines strongly emphasized on the importance of minimizing interruptions during chest compressions. However, those guidelines also stress the need for ventilations in the case of prolonged cardiac arrest (CA), and it is not at present clear at which point of CA the necessity of providing ventilations overcomes the hemodynamic compromise caused by chest compressions' interruption. ⋯ In this swine CA model, where defibrillation was first attempted at 10 minutes of untreated ventricular fibrillation, uninterrupted chest compressions resulted in significantly higher survival rates and higher 24-hour neurologic scores, compared with standard 30:2 CPR.

Ventricular fibrillation (VF) and asphyxia account for most cardiac arrests but differ in cardiac arrest course, neurologic deficit, and myocardial damage. In VF resuscitation, cardiac mitochondria were known to be damaged via excess generation of reactive oxygen species. This study evaluated the difference of cardiac mitochondrial damages between VF and asphyxial cardiac arrests. ⋯ Both VF and asphyxial cardiac arrests caused myocardial injuries and mitochondrial damages. Asphyxial cardiac arrest presented more diffuse myocardial injuries and more severe mitochondrial damages than VF cardiac arrest.

Randomized Controlled Trial Comparative Study
Comparing the efficacy of intravenous tenoxicam, lornoxicam, and dexketoprofen trometamol for the treatment of renal colic.
The aim of this study was to compare the efficacy and safety of 3 nonsteroidal anti-inflammatory drugs-intravenous tenoxicam, lornoxicam, and dexketoprofen trometamol-for the treatment of patients with renal colic. ⋯ Intravenous tenoxicam, lornoxicam, and dexketoprofen are all effective in the treatment of renal colic, although lornoxicam appears to reduce VAS pain scores with the fastest rate in this comparison.

Comparative Study
Bedside ultrasound performed by novices for the detection of abscess in ED patients with soft tissue infections.
The objective was to compare bedside ultrasound (US) to clinical examination for the detection of abscess. ⋯ Novice ED sonographers can identify abscesses with only minimal US training. Identification of abscess on US may change management of cutaneous abscesses.
