Emergency echocardiography to detect pericardial effusion in patients in PEA and near-PEA states.
Emergency echocardiography (EM echo) has been proposed to assist in decision-making in patients with pulseless electric activity (PEA) or PEA-like states. We observed the value of EM echo by emergency physicians in detecting pericardial effusion in patients in PEA and near PEA states. ⋯ Emergency echocardiography performed by emergency physicians in patients in PEA or near PEA states can detect pericardial effusions with correctable etiologies versus true PEA with ventricular standstill.

During reperfusion of ischemic myocardium nitric oxide (NO) reacts with superoxide radicals to form cardiotoxic peroxynitrite, which causes lipid peroxidation. Our hypothesis was that infusion of a NO donor S-nitroso-N-acetylpenicillamine (SNAP) during ischemia-reperfusion would exacerbate the oxidative damage to the myocardium by increased formation of nitrogen radicals. ⋯ The NO donor SNAP increased free radical concentration and exacerbated myocardial oxidative damage after ischemia-reperfusion.

The impact of the immediate in-hospital post-resuscitation care after out-hospital cardiac arrest is not well known. Based on treatment variables and laboratory findings a multiple logistic regression model was created for the prediction of survival at 6 months from the event. ⋯ This study suggests that in-hospital factors are associated with survival from out-of-hospital cardiac arrest. The mean blood glucose and serum potassium during the first 72 h of treatment and the use of beta-blocking agents were significantly and independently associated with survival.

The charts of all adult patients with accidental hypothermia who were admitted to a single academic hospital during a 10 year period were retrospectively retrieved. The aim was to identify factors associated with survival of those with hypothermic cardiac arrest. Of 75 admitted patients, 44 were found to be haemodynamically stable and not to require invasive rewarming measures. ⋯ Logistic regression analysis showed that of the 23 patients, 22 could be correctly classified as survivor or nonsurvivor based on the level of serum potassium and arterial pCO2. It is concluded that patients with cardiac arrest due to primary hypothermia tolerate long periods of conventional CPR before institution of CPB. The possible predictive role of serum potassium and arterial pCO2 needs further evaluation.

To clarify the incidence and survival rate of bystander-witnessed out-of-hospital cardiac arrests (OHCA) with cardiac etiology in Osaka Prefecture, Japan, with a population of nearly 9 million according to the Utstein style. ⋯ The incidence of bystander-witnessed (OHCA) with cardiac etiology and VF or VT were remarkably low compared with those reported by other studies conducted in some areas of Europe or the USA.
