Previous studies have documented poor quality CPR during real life resuscitation attempts. This study investigated whether poor quality CPR during advanced life support training could be contributing to poor performance in clinical practice. ⋯ The implementation of Guidelines 2005 into the ALS course appear to have improved the process of CPR by reducing no-flow time during simulated CPR. However, the quality of CPR during ALS training remains sub-optimal. Delays in starting CPR, inadequate compression depth, excessive interruptions in chest compressions and prolonged pre-shock pauses mirror observations from clinical practice. Strategies to improve CPR performance during ALS training should be explored and potentially may result in improvements in clinical practice.

Good quality basic life support (BLS) results in better survival. BLS is a core competence of nurses but despite regular refresher training, the quality of BLS is often poor and the reasons for this are not well known. We therefore investigated the relation between BLS quality and some of its potential determinants. ⋯ Male gender, greater self-confidence, recent BLS training and recent CPR were associated with better quality of BLS.

Commotio cordis or ventricular fibrillation caused by a blow to the chest is a rare cause of cardiac arrest in a well child. We report a case of a young child falling from a low height landing chest first with rapid onset of unconsciousness, apnoea and cyanosis. Cardiopulmonary resuscitation was given by parents under telephone instruction from an ambulance dispatch centre. ⋯ Specifically, a long QT was absent and a Flecainide challenge for Brugada syndrome was negative. There was no family history of sudden death. No further dysrrhythmia occurred and the child recovered neurologically well after 3 days of therapeutic hypothermia (for cerebral ischaemia) and 7 days of mechanical ventilation.

Review
Goal-directed hemodynamic optimization in the post-cardiac arrest syndrome: a systematic review.
The treatment recommendations from the 2005 International Consensus Conference on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science (hosted by the American Heart Association) advocate a goal-directed treatment strategy for hemodynamic optimization after return of spontaneous circulation (ROSC) in post-cardiac arrest care. We performed a systematic review to (1) examine the available evidence for goal-directed hemodynamic support in the post-cardiac arrest syndrome, (2) determine the effect of such a treatment strategy on survival, and (3) define the specific hemodynamic goals, if any, that have been tested in clinical trials of post-cardiac arrest patients. ⋯ To date, no clinical trials have examined hemodynamic optimization in post-cardiac arrest patients. Although clinical acumen may support the concept that hemodynamic derangements after ROSC should be normalized, there is currently no evidence available to indicate the best strategy for goal-directed hemodynamic support. The current study indicates the need for future clinical investigations designed to determine both the efficacy of hemodynamic optimization in post-cardiac arrest patients and the best endpoints to target as part of a goal-directed strategy.

Randomized Controlled Trial Comparative Study
The effectiveness of cardiopulmonary resuscitation instruction: animation versus dispatcher through a cellular phone.
We developed a cardiopulmonary resuscitation (CPR) instruction programme using motion capture animation integrated into cellular phones. We compared the effectiveness of animation-assisted CPR instruction with dispatcher-assisted instruction in participants with no previous CPR training. ⋯ Audiovisual animated CPR instruction through a cellular phone resulted in better scores in checklist assessment and time interval compliance in participants without CPR skill compared to those who received CPR instructions from a dispatcher; however, the accuracy of important psychomotor skill measures was unsatisfactory in both groups.
