Access of intraosseous (IO) compartments is a commonly used technique that is an invaluable asset in emergency resuscitation. Prehospital IO success rates using semi-automatic insertion devices vary between 70 and 100% of pediatric patients. There are limited data on time to insertion and duration of IO function in the prehospital setting. Recent studies limited to the pediatric emergency department (PED) setting have also suggested that IOs may be less successful in the infant population. We explored the use of IO access for pediatric resuscitation, encompassing the prehospital and pediatric emergency department (PED) settings. ⋯ This is the first study to provide time to IO access and IO duration in the prehospital setting, and the first prehospital evidence to suggest inferior IO function in infants <1 year old, compared to other ages. This highlights unique challenges for infants that have implications for the PED, interfacility transport, and critical care settings.

Case Reports
Ventricular Fibrillation Simulated Electrocardiogram Artifact by a Deep Brain Stimulator.
Deep brain stimulation devices can disrupt cardiac rhythm interpretation by causing electrocardiogram artifact. We report the case of a deep brain stimulating device initiating ventricular fibrillation simulated electrocardiogram artifact in the prehospital setting. Mimicked ventricular fibrillation due to a deep brain stimulator has not been documented, and if unrecognized could influence unwarranted or potentially harmful clinical decisions.

Objective: Hemostatic gauze application is an effective way to control major bleeding, which is the most common cause of death in trauma in both civilian and military settings. Coagulation derangement after acute exposure to high altitude might alter the effects of hemostatic gauzes. The present study aimed to observe the hemostatic effects of bio-zeolite gauze (BZG) and QuikClot Combat Gauze® (QCG) on major bleeding in rabbits acutely exposed to high altitude. ⋯ The concentrations of coagulation factor XII and factor X in rabbits acutely exposed to high altitude were significantly lower than those in lower altitude. At high altitude, the hemostatic effects of BZG did not decrease significantly compared to those in the lower altitude, whereas those of ordinary gauze and QCG decreased significantly at high altitude compared to those in the lower altitude. Conclusions: Coagulation derangement after acute exposure to high altitude has negative effects on ordinary gauze and QCG but has no significant negative hemostatic effects on BZG.

Little is known about survival outcomes after traumatic cardiac arrest in Asia, or the association of Utstein factors with survival after traumatic cardiac arrests. This study aimed to describe the epidemiology and outcomes of traumatic cardiac arrests in Asia, and analyze Utstein factors associated with survival. ⋯ In traumatic cardiac arrest, early aggressive resuscitation may not be futile and bystander CPR may improve outcomes.

This study aimed to investigate the effects of adding advanced cardiac life support (ACLS) training to an existing basic life support program and the operation of a designated team response for patients with out-of-hospital cardiac arrest (OHCA) on prehospital return of spontaneous circulation (ROSC) and ACLS management. ⋯ Additional ACLS training and operation of a designated OHCA team response were associated with higher rates of prehospital ROSC and prehospital ACLS provision. However, further research is needed to find the optimal operation for EMS to improve survival outcomes.
