Randomized Controlled Trial Comparative Study Clinical Trial
CPR for children: one hand or two?
Current guidelines for chest compressions in CPR advocate a one handed technique in children (1-8 years old) and a two handed technique in adults (>8 years old). No previous study has examined whether these two techniques generate different compression pressures. This study assesses the relative difference in intrathoracic compression pressures generated by one- and two handed chest compression techniques in a paediatric manikin. ⋯ Two handed chest compression CPR seems to be easier to perform on a paediatric resuscitation manikin and produces significantly higher mean and peak pressures. Further work is needed to determine the comparative effects on children and which technique produces better clinical outcomes.

Review Historical Article
Open-chest cardiopulmonary resuscitation: past, present and future.
Out-of-hospital cardiac arrests account for approximately 1000 sudden cardiac deaths per day in the United States. Since its introduction in 1960 closed-chest cardiac massage (CCCM) often takes place as an attempt at resuscitation, although its survival rates are low. Other resuscitation techniques are available to physicians such as open-chest cardiopulmonary resuscitation (OCCPR). ⋯ Surprisingly, the incidence of infectious complications after thoracotomy in an unprepared chest is low. The vast majority of the patients' families accept OCCPR as a therapeutic choice for cardiac arrests and it has been showed to be economically viable. This paper reviews some of the basic and advanced concepts of this evolving technique.

Without an easy method to monitor the performance of prehospital cardiopulmonary resuscitation (CPR), earlier studies have not been able to assess the quality of CPR. In this study, we have used a new approach to evaluate prehospital CPR performance and the impact on outcome using data retrieved from the automatic external defibrillators (AED). ⋯ The quality of prehospital CPR is associated with a greater likelihood of survival in witnessed VF arrests in need of post-shock CPR. The potential of widely available electrocardiography and voice records in AEDs in providing a convenient and real-time evaluation of prehospital CPR should be explored further.

Comparative Study
Influence of dobutamine on the variables of systemic haemodynamics, metabolism, and intestinal perfusion after cardiopulmonary resuscitation in the rat.
Global left ventricular dysfunction after successful resuscitation from cardiac arrest may be treated successfully with dobutamine but the effects on intestinal perfusion are unknown. ⋯ Dobutamine enhances the recovery of global haemodynamic and metabolic variables early after cardiac arrest.

The purpose of this study was to report the locality of out-of-hospital cardiac arrest (OHCA) in the city of Goteborg and to identify implications for public access defibrillation (PAD). ⋯ Among patients suffering from out-of-hospital cardiac arrest in Goteborg in whom resuscitation efforts were attempted 17% of all cardiac arrests were regarded as generally suitable for PAD. According to previous suggestions, the indication for public access defibrillation is in a place with a reasonable probability of use of one AED in 5 years. Several high-incidence sites that probably would benefit from defibrillator availability could be identified, and 54 patients (2.5%) arrested in these sites.
