This study was performed to determine the potential efficacy of an automated device with a load-distributing band (AutoPulse, Revivant Corporation), in improving neurologically intact survival after cardiac arrest. ⋯ Improved hemodynamics with AutoPulse performed CPR results in improved neurologically intact survival without subsequent thoracic or pulmonary injuries in this porcine model of prolonged cardiac arrest.

Modern neuroimaging safely and reliably diagnoses stroke and provides information for outcome prediction. However, some patients with clinical stroke have no detectable abnormality on neuroimaging and other patients are not fit for such investigations. Therefore, we evaluated the potential of plasma DNA and serum S100 protein concentrations to predict post-stroke mortality and morbidity in patients with negative neuroimaging results. ⋯ Plasma DNA concentrations > 800 kilogenome-equivalent/l have a sensitivity of 42% and a specificity of 100% for predicting 6-month post-stroke mRS (grades 0-2), with an area under the receiver operator characteristic (ROC) curve of 0.742. By comparison, serum S100 protein concentrations > 0.09 microg/l have a sensitivity of 48% and specificity of 75% for predicting 6-month post-stroke mRS (grades 0-2), and the area under the curve is 0.542. Plasma DNA concentration predicts post-stroke morbidity and mortality in patients with negative neuroimaging, and may be more effective than S100 protein measurement.

Case Reports
Rescue therapy with terlipressin by continuous infusion in a child with catecholamine-resistant septic shock.
A 2-month-old female infant presented with septic shock, refractory to high doses of catecholamines. Continuous infusion of terlipressin at a rate of 10 mcg/kgh produced a significant increase in the mean arterial pressure that was evident within half and hour, so allowing a reduction in the rate of catecholamine infusion. However, 18 h later, the blood pressure fell again and finally the patient died. This case shows the potential value of terlipressin infusion to restore normal mean arterial pressure in children with vasodilatory shock and hypotension refractory to catecholamines.

In 2003 severe acute respiratory syndrome (SARS) affected 1,755 people in Hong Kong, including 386 health care professionals, some of whom were infected during resuscitation attempts of affected patients. This study seeks to explore whether this epidemic has altered the willingness of Hong Kong medical students to perform basic life support and mouth-to-mouth ventilation during an out-of-hospital cardiac arrest. ⋯ Hong Kong medical students feel able to perform BLS if required. They are concerned about the risk of disease transmission, including SARS, during resuscitation, but would be more likely to withhold mouth-to-mouth resuscitation in the presence of vomit or blood than due to a fear of contracting SARS.

This report describes the case of an 88-year-old non-diabetic female who presented to the emergency department following a presumed hypoglycaemic collapse due to self-neglect. Subsequent rewarming and resuscitation demonstrated a number of the significant consequences of severe hypothermia, including apparent secondary impairment of glycaemic autoregulation. ⋯ Subsequent blood sugar level monitoring was normal. If insulin is administered to the hypothermic patient, intensive monitoring of blood glucose is essential due to the increase in endogenous insulin secretion on rewarming.
