Resuscitation
-
Cardiopulmonary Resuscitation is an important component of the pre-hospital emergency care process. Location of the correct site for application of compression in External Cardiac Compression is crucial if patients are not to be exposed to the risk of iatrogenic injury. ⋯ Results indicated that, using the most conservative comparison, such pressure would be applied in 97% of instances, if the rescuer strictly adhered to the caliper method for locating the correct site. It is recommended that the caliper method be removed as an approved procedure.

Do not attempt resuscitation (DNAR) decision-making and recording in case notes can be poor. We have audited current practices pertaining to DNAR orders in a district hospital before and after the introduction of a standardised order form (SOF). ⋯ Documentation of DNAR decisions in medical case notes is poor. Standardised order forms, based on recommended national guidelines that complement case note entries, improve the process and recording of this sensitive decision.

Comparative Study
Prehospital ECG transmission: comparison of advanced mobile phone and facsimile devices in an urban Emergency Medical Service System.
To compare the speed and reliability of electrocardiogram (ECG) transmissions from the prehospital setting to a conventional table facsimile device and to an advanced mobile phone in a Helicopter Emergency Medical Service System (HEMS). ⋯ An advanced mobile phone is as fast and reliable as a conventional table fax in receiving ECGs. A mobile phone with advanced features is a practical tool for HEMS physicians who need to evaluate ECGs in the prehospital setting.

In some patients with ventricular fibrillation (VF) there may be a better chance of successful defibrillation after a period of chest compression and ventilation before the defibrillation attempt. It is therefore important to know whether a defibrillation attempt will be successful. The predictive power of a model developed by 'genetic' programming (GP) to predict defibrillation success was studied. ⋯ The VF ECG contains information predictive of defibrillation success. The model developed by GP, including data from the time-domain, frequency-domain and nonlinear dynamics, could reduce the incidence of unsuccessful defibrillations.

Myocardial dysfunction occurs immediately after successful cardiac resuscitation. Our purpose was to determine whether measurement of cardiac troponin I in children with acute out-of-hospital cardiac arrest predicts the severity of myocardial injury. ⋯ After cardiac arrest and resuscitation in pediatric patients, the severity of myocardial dysfunction was reflected in troponin I levels.
