Comparative Study
Early administration of xenon or isoflurane may not improve functional outcome and cerebral alterations in a porcine model of cardiac arrest.
Xenon (Xe) is neuroprotective when given 1h after cardiopulmonary resuscitation (CPR). Here, we investigated if an earlier administration of Xe or isoflurane (Iso) would also reduce neurological dysfunction. ⋯ In this study early administration of Xe and Iso did not significantly reduce neurological dysfunction and histopathological alterations induced by cardiac arrest and CPR.

Randomized Controlled Trial Comparative Study
Slow infusion of calcium channel blockers compared with intravenous adenosine in the emergency treatment of supraventricular tachycardia.
The emergency treatment of supraventricular tachycardia (SVT) has, over the last two decades, changed from verapamil to adenosine primarily owing to documented hypotensive episodes occurring with rapid bolus infusions of the calcium channel blocker. Slow infusions of calcium channel blockers have not previously demonstrated hypotension to any significant degree. The aim of this study was to compare the efficacy and safety of bolus intravenous adenosine and slow infusion of the calcium channel blockers verapamil and diltiazem in the emergency treatment of spontaneous SVT. ⋯ Slow infusion of calcium channel blockers is an alternative to adenosine in the emergency treatment of stable patients with SVT. Calcium channel blockers are safe and affordable for healthcare systems where the availability of adenosine is limited.

Rapid intra-arrest induction of hypothermia using total liquid ventilation (TLV) with cold perfluorocarbons improves resuscitation outcome from ventricular fibrillation (VF). Cold saline intravenous infusion during cardiopulmonary resuscitation (CPR) is a simpler method of inducing hypothermia. We compared these 2 methods of rapid hypothermia induction for cardiac resuscitation. ⋯ Moderate hypothermia was achieved rapidly during VF and CPR using both cold saline infusion and cold TLV, but ROSC was higher than control only in cold TLV animals, probably due to better CPP and pO(2). The method by which hypothermia is achieved influences ROSC.

Acute life-threatening events in children are medical emergencies requiring immediate intervention. They can be due to cardiac arrest, respiratory arrest or another cause of sudden compromise for example, choking. Internationally, hospital systems are being introduced to reduce preventable acute life-threatening events and, despite having significant resource implications, have not yet been subject to economic analysis. This study presents the additional short-term health service costs of in-hospital acute life-threatening events to inform a cost-effectiveness analysis of prevention strategies. ⋯ The short-term costs of paediatric in-hospital acute life-threatening events, including cardiac arrest, from an NHS perspective, are more expensive than those reported for adults, but similar to other life saving treatments. This new information will serve to improve efficiency in the current resuscitation programme and contribute to cost-effectiveness analysis of prevention strategies.
