Resuscitation

This study aimed to determine whether cardiopulmonary resuscitation (CPR) volume is associated with survival to discharge rate for out-of hospital cardiac arrest (OHCA) victims. ⋯ Emergency departments with high volumes of CPR cases showed significantly better outcomes for OHCA patients than those with low volumes in an EMS system with single-tiered basic to intermediate service level.

Randomized Controlled Trial Comparative Study
Effectiveness of the new 'Mobile AED Map' to find and retrieve an AED: A randomised controlled trial.
Although early shock with an automated external defibrillator (AED) is one of the several key elements to save out-of-hospital cardiac arrest (OHCA) victims, it is not always easy to find and retrieve a nearby AED in emergency settings. We developed a cell phone web system, the Mobile AED Map, displaying nearby AEDs located anywhere. The simulation trial in the present study aims to compare the time and travel distance required to access an AED and retrieve it with and without the Mobile AED Map. ⋯ Although the new Mobile AED Map reduced the travel distance to access and retrieve the AED, it failed to shorten the time. Further technological improvements of the system are needed to increase its usefulness in emergency settings (UMIN000002043).

Randomized Controlled Trial Comparative Study
The effect of a cellular-phone video demonstration to improve the quality of dispatcher-assisted chest compression-only cardiopulmonary resuscitation as compared with audio coaching.
Bystander cardiopulmonary resuscitation (CPR) has shown to significantly improve the survival of cardiac-arrest victims. Dispatcher assistance increases the number of bystanders who perform CPR, but the quality of CPR remains unsatisfactory. This study was conducted to assess the effect of video coaching on the performance of CPR by untrained volunteers when compared with traditional audio instruction in simulated cardiac arrests. ⋯ Instructions from the dispatcher, along with a video demonstration of CPR, improved the time to initiate compression, the compression rate and the correct hand positioning. It also reduced the 'hands-off' events during CPR. However, emphasised instructions by video may be needed to increase the depth of compressions.

Comparative Study
A rapid, safe, and low-cost technique for the induction of mild therapeutic hypothermia in post-cardiac arrest patients.
The benefits of inducing mild therapeutic hypothermia (MTH) in cardiac arrest patients are well established. Timing and speed of induction have been related to improved outcomes in several animal trials and one human study. We report the results of an easily implemented, rapid, safe, and low-cost protocol for the induction of MTH. ⋯ A protocol using a combination of core and surface cooling modalities was rapid, safe, and low cost in achieving MTH. The cooling rate of 2.6°C/h was superior to most published protocols. This method uses readily available equipment and reduces the need for costly commercial devices.

Comparative Study
Effects of arterial oxygen content on oxidative stress during resuscitation in a rat hemorrhagic shock model.
To examine whether reactive oxygen species (ROS) production is affected by arterial oxygen content (CaO(2)) in attempted resuscitation to restore blood pressure from hemorrhagic shock (HS) or not. ⋯ In a rat HS model, attempted resuscitation to restore blood pressure increased O(2) UC as well as %CoQ9. However, the magnitude of %CoQ9 increase that represents ROS production is not affected by CaO(2) during resuscitation from HS.
