Randomized Controlled Trial Clinical Trial
A randomized controlled trial of chest compression only CPR for older adults-a pilot study.
Older people are trained infrequently in cardiopulmonary resuscitation (CPR), yet are more likely to witness a cardiac arrest. Older people who are CPR trained perform CPR when witnessing a cardiac arrest. ⋯ We identified low rates of CPR skill retention in this elderly population. CC-CPR instruction was associated with equivalent skill retention rates compared with traditional CPR instruction. No demographic factors were associated with successful skill retention.

A tremendous amount of public resources are focused on improving cardiac arrest (OHCA) survival in public places, yet most OHCAs occur in private residences. ⋯ Many important characteristics of cardiac arrest patients and the bystander differ in public versus private locations. Fundamentally different strategies are needed to improve survival from these events.

Comparative Study
Intestinal ischaemia during cardiac arrest and resuscitation: comparative analysis of extracellular metabolites by microdialysis.
Intestinal ischaemia is a major complication of shock syndromes causing translocation of bacteria and endotoxins and multiple organ failure in intensive care patients. The present study was designed to use microdialysis as a tool to monitor intestinal ischaemia after cardiac arrest and resuscitation in pigs. For this purpose, microdialysis probes were implanted in pig jejunal wall, peritoneum, skeletal muscle and brain, and interstitial fluid was obtained during circulatory arrest (induced by ventricular fibrillation) and after return of spontaneous circulation (ROSC). ⋯ Brain and muscle samples showed similar changes as in intestinum and peritoneum except for glutamate, which was increased in brain but not in muscle. We conclude that intestinal ischaemia occurs as a consequence of cardiac arrest and resuscitation and can be monitored by in vivo microdialysis. Comparative analysis by multi-site microdialysis reveals that the intestine is equally or even more sensitive to ischaemia than brain or muscle.

Several reports demonstrate non-specific hyperamylasemia in cardiac surgery or diabetic ketoacidosis. We report here for the first time non-specific hyperamylasemia in a cardiovascular beri-beri case who showed shock with severe metabolic acidosis. Her echocardiography revealed hyperkinetic wall motion of the small left ventricle. ⋯ Thiamine administration dramatically reversed her haemodynamic derangements, metabolic acidosis and even relieved her abdominal pain. Isozyme examinations for hyperamylasemia showed that most of the serum amylase consisted of salivary type. This case report expands our information on non-specific hyperamylasemia encountered in the emergency setting.

Case Reports
Gas gangrene pyaemia with myocardial abscess formation--fatal outcome from a rare infection nowadays.
We report a case of sudden death after gas gangrene. A 67-year-old male patient with diabetes mellitus and chronic renal failure (on haemodialysis three times a week) presented in the surgical emergency department with a severe swelling and crepitation in the right groin. No signs of trauma were present-except for a well-healed, 1-year-old scar after femoro-popliteal bypass surgery. ⋯ Abscess formation was found in the myocardium. Clostridial gas gangrene is a rare clinical condition. Unless immediate diagnosis and adequate therapy measures are taken, the outcome and chances for survival are poor as demonstrated by this case.
