Randomized Controlled Trial Comparative Study
Simplified dispatch-assisted CPR instructions outperform standard protocol.
Dispatch-assisted chest compressions only CPR (CC-CPR) has gained widespread acceptance, and recent research suggests that increasing the proportion of compression time during CPR may increase survival from out-of-hospital cardiac arrest. We created a simplified CC-CPR protocol to reduce time to start chest compressions and to increase the proportion of time spent delivering chest compressions. This simplified protocol was compared to a published protocol, Medical Priority Dispatch System (MPDS) Version 11.2, recommended by the National Academies of Emergency Dispatch. ⋯ The simplified protocol was as good as, or better than the MPDS v11.2 protocol in every aspect studied except hand position, and the simplified protocol resulted in significant time savings. The protocol may need modification to ensure correct hand position. Time savings and improved quality of CPR achieved by the new set of instructions could be important in strengthening critical links in the cardiac chain of survival.

The size 1 LMA-ProSeal: Comparison with the LMA-Classic during pressure controlled ventilation in a neonatal intubation manikin.
The classic laryngeal mask airway (cLMA) has been demonstrated to be effective for airway management during neonatal resuscitation. However, high airway pressures, when required, cannot be achieved with this device. A neonatal prototype of the LMA-ProSeal (PLMA), which might improve the oropharyngeal leak pressure, has recently been produced. The airway sealing pressures of the cLMA and the PLMA were compared in a neonatal manikin. ⋯ The neonatal PLMA allows higher airway pressure ventilation than the cLMA, in a neonatal intubation manikin. If confirmed clinically, this may have important implications during neonatal resuscitation when high airway pressures are required.

Hypertonic saline during CPR: Feasibility and safety of a new protocol of fluid management during resuscitation.
In experimental studies infusion of hypertonic saline during cardiopulmonary resuscitation (CPR) increased resuscitation success rate and improved myocardial and cerebral reperfusion during CPR. We tested the feasibility and the safety of this new therapeutic measure in a randomised, preclinical pilot study. ⋯ HHS after CA is feasible and safe and might improve short term survival after CPR. However, whether giving HHS could be a useful measure to increase resuscitation success after out-of-hospital CA requires a larger preclinical trial.

CPREzy improves performance of external chest compressions in simulated cardiac arrest.
External chest compression (ECC) is an essential part of cardiopulmonary resuscitation and usually performed without any adjuncts. Although different supportive devices have been developed, none have yet been implemented as a standard procedure to guide rescuers in resuscitation. This study investigates the effects of the CPREzy-pad on ECC performed by first year medical students during simulated cardiac arrest. ⋯ CPREzy as a simple portable and re-usable device is able to improve performance of ECC in simulated cardiac arrest.
