Clinical Trial
Focused echocardiographic evaluation in life support and peri-resuscitation of emergency patients: a prospective trial.
Focused ultrasound is increasingly used in the emergency setting, with an ALS-compliant focused echocardiography algorithm proposed as an adjunct in peri-resuscitation care (FEEL). The purpose of this study was to evaluate the feasibility of FEEL in pre-hospital resuscitation, the incidence of potentially treatable conditions detected, and the influence on patient management. ⋯ Application of ALS-compliant echocardiography in pre-hospital care is feasible, and alters diagnosis and management in a significant number of patients. Further research into its effect on patient outcomes is warranted.

To evaluate whether the inclusion of any specific resuscitation training educational strategy in developing countries improves outcomes. ⋯ Resuscitation training in developing countries was well received and viewed as valuable training by the students and local counterparts. Important student, training environment characteristics, educational outcomes and patient outcomes were inconsistently defined and reported. Institution of training in trauma and newborn resuscitation in developing countries has significantly reduced mortality, but this has not been demonstrated with other training programs.

The aim of this investigation was to estimate and contrast the global incidence and outcome of out-of-hospital cardiac arrest (OHCA) to provide a better understanding of the variability in risk and survival of OHCA. ⋯ OHCA incidence and outcome varies greatly around the globe. A better understanding of the variability is fundamental to improving OHCA prevention and resuscitation.

Echocardiography performed in an ALS-compliant manner provides a tool whereby some of the potentially reversible causes of cardiac arrest can be diagnosed in real time by minimally trained practitioners. One of the major concerns this raises is how to deliver effective training to the required standard. The objective of this study was to determine the effectiveness of number of different educational methods used teach echocardiography to novices. This involved assessment of cognitive, psychomotor skills and affective aspects in five key areas. ⋯ Novice echocardiographers can obtain knowledge and skills relevant to ALS-compliant peri-resuscitation echocardiography using a range of educational techniques. In addition to the standard one-day training courses available, continued mentored practice and didactic adherence to ALS algorithms is required.

In 2005, the AHA changed the treatment recommendation for shockable rhythms from 3 transthoracic stacked-shocks to a single shock followed by immediate chest compressions. The stacked-shock recommendation was based on low first-shock efficacy of monophasic waveforms and the theoretical decrease in transthoracic impedance (TTI) following each shock. The objective of this study was to characterize TTI following biphasic defibrillation attempts in children ≥ 8 yrs during cardiac arrest to assess whether a stacked-shock approach may be appropriate to improve defibrillation success. ⋯ During cardiac arrests in children ≥ 8 yrs, TTI decreased after biphasic shocks, but the limited magnitude and duration of TTI changes suggest that stacked-shocks would not improve defibrillation success.
