This prospective study evaluated the acquisition and retention of skills in cardio-pulmonary resuscitation (CPR) and the use of the automated external defibrillator (AED) by lay volunteers involved in the Department of Health, England National Defibrillator Programme. One hundred and twelve trainees were tested immediately before and after and initial 4-h class; 76 were similarly reassessed at refresher training 6 months later. A standardised test scenario that required assessment of the casualty, CPR and the use of on AED was evaluated using recording manikin data and video recordings. ⋯ Initial training improved performance of all CPR skills, although all except compression rate had deteriorated after 6 months. The proportion of subjects able to correctly perform most CPR skill was higher following refresher training that after the initial class. Although this course was judged to be effective in teaching delivery of counter-shocks, the need was identified for more emphasis on positioning of electrodes, pre-shock safety checks, airway opening, ventilation volume, checking for signs of a circulation, hand positioning, and depth and rate of chest compressions.

Successful outcome following cardiac arrest have been reported in the range of 13-59%. It is well established that the time from the onset of a ventricular arrhythmia to successful defibrillation predicts outcome. Recent out of hospital arrest protocols minimizing time to defibrillation have reported significant improvement in outcomes. The Bethesda conference and American Heart Association (AHA) both set standards for defibrillation time for in hospital codes but do not set standards for other interventions. In February 2000, the Brooke Army Medical Center (BAMC) cardiopulmonary resuscitation committee published time guidelines for the initiation of CPR, emergency team arrival, first defibrillation and first medication. We sought to evaluate resuscitation outcomes before and after this intervention. ⋯ Setting time guidelines for Advanced Cardiac Life Support (ACLS) improved initiation of CPR, emergency team arrival, first defibrillation, and first medication administration. These time reductions were accompanied by improved event survival and a statistically improved survival to discharge.

Infectious complications in survivors of cardiac arrest admitted to the medical intensive care unit.
To describe the incidence, associated factors and outcome of infectious complications in patients admitted to the medical intensive care unit (MICU) after cardiopulmonary resuscitation (CPR). ⋯ Infectious complications are common in survivors of cardiac arrest and are associated with increased morbidity.

Comparative Study
Asian medical staff attitudes towards witnessed resuscitation.
To assess and compare local Emergency Department medical and nursing staff attitudes towards witnessed resuscitation. ⋯ Locally, we found that medical staff are generally not in favour of witnessed resuscitation. More research is needed to assess attitudes of the general public, and whether this diverges greatly from medical staff attitudes.

Activated neutrophils play a pivotal role in resuscitation injury. The strategies used for resuscitation (types of fluids and methods of administration) can affect the degree of neutrophil activation. The aim of this study was to test the commonly available resuscitation fluids in a large animal model of hemorrhagic shock to determine the strategy associated with the least degree of neutrophil activation. ⋯ Artificial colloids and LR (independent of rate or volume of infusion) caused significant neutrophil activation, which was not seen with albumin and whole blood resuscitation. These findings suggest that the type of resuscitation fluid and method of infusion can influence neutrophil function.
