Randomized Controlled Trial Comparative Study Clinical Trial
Efficacy of the laryngeal tube by inexperienced personnel.
We compared the laryngeal tube and the laryngeal mask in the ease of insertion, ventilation volume and the incidence of gastric insufflation by inexperienced personnel. In a randomized, cross-over design, each of 28 students of a Fire Defense Academy attempted to insert the laryngeal tube and laryngeal mask in turn using an airway management trainer manikin. A self-inflating bag (2000 ml) was attached and ventilation volume was measured. ⋯ The incidence of gastric insufflation was significantly lower for the laryngeal tube (2 times) than for the laryngeal mask (10 times) (P < 0.05). Twenty six of 28 students stated that insertion of the laryngeal tube was easier than insertion of the laryngeal mask, whereas the remaining two stated that there was no difference in the ease of insertion between two devices. Therefore, the laryngeal tube has a potential role in providing a clear airway during cardiopulmonary resuscitation.

Comparative Study
Neurological recovery by EEG bursting after resuscitation from cardiac arrest in rats.
The return of neurological function during the early period after resuscitation from cardiac arrest (CA) has not been evaluated systematically. We report the temporal analysis of EEG bursting pattern during the very early periods after resuscitation. ⋯ Increased EEG bursting during first 30-40 min after resuscitation from moderate to severe ACA was observed in rats with good neurological outcome at 24 h. Early EEG bursting patterns may provide additional prognostication after resuscitation from CA.

The aim of this study was to determine community application of cardiopulmonary resuscitation (CPR) skills in an emergency, and, thus, assess the value of training programmes in raising community competence. A cross-sectional telephone survey of the Western Australian population was chosen randomly (n = 803). An urban sub-sample (n = 100) performed a practical demonstration of CPR skills using a simulated collapse scenario using a recording manikin as the victim. ⋯ Theoretical competence poorly reflected practical performance in many tasks. This study provides a comprehensive database of CPR training and performance, and highlights future directions to ensure appropriate and cost-effective training. Specific factors to be addressed include increasing frequency of training, targeting of high-risk groups, simplification in teaching, and emphasising early activation of the emergency medical system.
