Both a written cognitive knowledge evaluation and a practical evaluation that tests psychomotor skills, cognitive knowledge, and affective behaviors such as leadership and team skills are required for successful completion of American Heart Association (AHA) Advanced Cardiovascular Life Support (ACLS) course. The 2005 International Liaison Committee on Resuscitation (ILCOR) Consensus on Science and Treatment Recommendations noted that in Basic Life Support (BLS) there is little to no correlation between written and practical skills. The current study was conducted to determine if there is a correlation between written and practical evaluations in an ACLS course. ⋯ The ACLS written evaluation was not a predictor of participant skills in managing a simulated cardiac arrest event immediately following an ACLS course. The single case simulations used in ACLS skills evaluation test a narrow portion of ACLS content while written evaluation tests can more practically test a broader spectrum of content. Both work in concert to define participant knowledge and neither should be used exclusively to determine participant competence.

The purpose of this study was to measure the local electrical field or potential gradient, measured with a catheter-based system, required to terminate long duration electrically or ischaemically induced ventricular fibrillation (VF). We hypothesized that prolonged ischaemic VF would be more difficult to terminate when compared to electrically induced VF of similar duration. ⋯ Defibrillation of prolonged VF produced by acute myocardial ischaemia requires a significantly greater potential gradient to terminate than prolonged VF induced by electrical stimulation of the right ventricular endocardium. The VF duration used in this study approximates that occurring in victims of out-of-hospital cardiac arrest. Our findings may be of clinical importance in the management of such patients.

Vasoconstriction, an inherent property of Hemoglobin Based Oxygen Carriers (HBOC) potentially due to nitric oxide (NO) scavenging, may increase cardiovascular complications in HBOC resuscitated trauma patients. The purpose of this study was to determine if co-administration of a weak NO donor, intravenous nitroglycerin (NTG), with HBOC-201 during resuscitation from hemorrhagic shock could safely attenuate HBOC-201 vasoconstriction. ⋯ Nitroglycerin attenuates vasoconstrictive properties of HBOC when co-administered during resuscitation in this swine model of hemorrhagic shock. Translational survival studies are required to determine if this strategy of attenuation of the vasoconstriction of HBOC-201 reduces cardiovascular complications and improves outcome with HBOC fluid resuscitation for hemorrhagic shock.

Induction of hypothermia is generally accepted to increase survival of out-of-hospital cardiac arrest, but lack of initiation of this treatment has been frequently reported. When patients remain in coma after treatment with hypothermia, determination of prognosis is difficult. Furthermore, little is known about the methods used in clinical practice to predict outcome after cardiopulmonary resuscitation (CPR). The aim of the present survey was to evaluate self-reported implementation of hypothermia after CPR and the methods used to predict neurological outcome at Intensive Care Units (ICUs) in the Netherlands. ⋯ In the Netherlands, the use of therapeutic hypothermia after CPR is reported by 92% of ICUs which, compared to previous reports, is an exceedingly high percentage. Neurological outcome is reported to be predicted mainly by neurological examination and SSEP or a combination of these and other assessments. The method used varies substantially between ICUs.

It is possible that the exportation of North American and European models has hindered the creation of a structured cardiopulmonary resuscitation (CPR) training programme in developing countries. The objective of this paper is to describe the design and present the results of a European paediatric and neonatal CPR training programme adapted to Honduras. ⋯ The training of independent paediatric CPR groups with the collaboration and scientific assessment of an expert group could be a suitable model on which to base paediatric CPR training in Latin American developing countries.
