Randomized Controlled Trial Comparative Study
A randomized trial of the capability of elderly lay persons to perform chest compression only CPR versus standard 30:2 CPR.
Early cardiopulmonary resuscitation (CPR) improves survival after cardiac arrest, but there is a discrepancy between the age group normally attending CPR-classes and the age group most likely to witness a cardiac arrest. We wanted to study if elderly lay persons could perform 10min of CPR on a realistic manikin with continuous chest compressions (CCC) and conventional CPR (30:2). ⋯ Lay people in the age group 50-76 were able to perform CPR with acceptable quality for 10min and we found only very slight temporal quality deterioration. This makes training programs for the elderly meaningful to improve survival after cardiac arrest.

Comparative Study
Esophageal temperature after out-of-hospital cardiac arrest: an observational study.
Out-of-hospital cardiac arrest (OHCA) is a significant cause of death and severe neurological disability. The only post-return of spontaneous circulation (ROSC) therapy shown to increase survival is mild therapeutic hypothermia (MTH). The relationship between esophageal temperature post OHCA and outcome is still poorly defined. ⋯ Following OHCA all patients have esophageal temperatures below normal in the pre-hospital phase and on arrival in the Emergency Department. Patients who achieve ROSC following OHCA and survive to hospital discharge are warmer on arrival in ICU and take longer to reach target MTH temperatures compared to patients who die in hospital. The mechanisms of action underlying esophageal temperature and survival from OHCA remain unclear and further research is warranted to clarify this relationship.

Telephone-cardiopulmonary resuscitation (CPR) advice aims to increase the quality and quantity of bystander CPR, one of the few interventions shown to improve outcome in cardiac arrest. We evaluated a current paediatric telephone protocol (AMPDS v11.1) to assess the effectiveness of verbal CPR instructions in paediatric cardiac arrest. ⋯ Although current telephone-CPR instructions improve the numbers of children in whom bystander CPR is attempted, effectiveness is likely to be limited by the significant delays in actually delivering basic life support.

This study aimed to report results of pre-hospital cardiopulmonary resuscitation (CPR) in the city of Prague in accordance with 'Utstein-style' recommendations. ⋯ In 2008, our ambulance crew performed 493 CPRs. Return of spontaneous circulation (ROSC) was achieved in 278 cases (56.3%), survival of the event in 211 cases (42.8%) and survival to hospital discharge with good neurological outcome (CPC 1 or 2) in 74 cases (15.0%). Appropriate figures for patients with first shockable rhythm (n=146) were 106 (72.6%) for ROSC, 91 (62.3%) for survived event and 51 (34.9%) for survival to discharge with good neurological outcome. Pre-hospital CPR incidence was 41.1 per 100,000 inhabitants. The majority of cases had a cardiac origin (363, 73.6%). The physician attending the arrest declared the reason unknown in 40 cases (8.1%), as a respiratory disease in 20 cases (4.1%) and in 36 cases (7.3%) the arrest was a result of trauma, drowning or poisoning.

To investigate if body temperature as measured with a prototype of a non-invasive continuous cerebral temperature sensor using the zero-heat-flow method to reflect the oesophageal temperature (core temperature) during mild therapeutic hypothermia after cardiac arrest. ⋯ Body temperature measurements using a non-invasive continuous cerebral temperature sensor prototype that uses the zero-heat-flow method accurately reflected oesophageal temperature measurements during mild therapeutic hypothermia in patients with restoration of spontaneous circulation after cardiac arrest.
