Randomized Controlled Trial Comparative Study
A randomized comparison of the Laryngoscope with Fiber Optic Reusable Flexible Tip English Macintosh blade to the conventional Macintosh laryngoscope for intubation in simulated easy and difficult child airway with chest compression scenarios.
We hypothesized that the Laryngoscope with Fiber Optic Reusable Flexible Tip English Macintosh blade (TMAC) is beneficial for the intubation of child manikins while performing cardiopulmonary resuscitation (CPR). In the present study, we evaluated the effectiveness of the conventional Macintosh laryngoscope (MAC) and TMAC in 3 simulated CPR scenarios. ⋯ The TMAC seems to be a superior intubating device compared with the conventional MAC when used in simulated normal and difficult child airway with chest compression scenarios. Future studies should explore the efficacy of TMAC in pediatric clinical emergency settings.

Randomized Controlled Trial Comparative Study
Comparison of intubation through the McGrath MAC, GlideScope, AirTraq, and Miller Laryngoscope by paramedics during child cardiopulmonary resuscitation: a randomized crossover manikin trial.
Advanced airway management and endotracheal intubation (ETI) during cardiopulmonary resuscitation (CPR) is more difficult than, for example, during anesthesia. However, new devices such as video laryngoscopes should help in such circumstances. The aim of this study was to compare the performance of 4 intubation devices in pediatric manikin-simulated CPR. ⋯ Child ETI performed by paramedics during uninterrupted chest compression often has a low success rate. In contrast, McGrath, GlideScope, and AirTraq intubation devices are fast, safe, and easy to use. Within the limitations of a manikin study, this study suggests that inexperienced medical staff might benefit from using video laryngoscopy devices for child emergency airway management.

Randomized Controlled Trial
Compressing with dominant hand improves quality of manual chest compressions for rescuers who performed suboptimal cardiopulmonary resuscitation in manikins.
The question of whether the placement of the dominant hand against the sternum could improve the quality of manual chest compressions remains controversial. In the present study, we evaluated the influence of dominant vs nondominant hand positioning on the quality of conventional cardiopulmonary resuscitation (CPR) during prolonged basic life support (BLS) by rescuers who performed optimal and suboptimal compressions. ⋯ Chest compression quality significantly improved when the dominant hand was placed against the sternum for those who performed suboptimal compressions during conventional CPR.

Randomized Controlled Trial Comparative Study
Comparison of infant intubation through the TruView EVO2, TruView PCD, and Miller laryngoscope by paramedics during simulated infant cardiopulmonary resuscitation: A randomized crossover manikin study.
The aim of the study was to compare the efficacy of the TruView EVO2, TruView PCD, and Miller laryngoscopes for tracheal intubation during cardiopulmonary resuscitation with and without chest compressions (CCs) by paramedics in an infant manikin model. ⋯ For infant tracheal intubation with TruView PCD, when used by paramedics, the malleable TruView PCD showed shorter intubation time and higher overall success rate in a simulated CC scenario than TruView EVO2 or Miller laryngoscopes. Further clinical studies are necessary to confirm these initial positive findings.

Randomized Controlled Trial
Modified carotid sinus massage using an ultrasonography for maximizing vagal tone: a crossover simulation study.
The aim of this study was to ascertain if a modified carotid sinus massage (CSM) using ultrasonography is superior to the conventional CSM for vagal tone generation. ⋯ The modified CSM using ultrasonography might be more useful than the conventional CSM in reverting episodes of paroxysmal supraventricular tachycardia and may be a suitable alternative for treating the same in the emergency department.
