Survival from out of hospital cardiac arrest (OHCA) increases when effective cardiopulmonary resuscitation (CPR) and defibrillation are performed early. Patients who suffer OHCA in front of emergency medical services (EMS) clinicians have greater likelihood of survival, but little is known about how EMS clinicians think about and experience those events. We sought to understand how EMS clinicians assessed patients who devolved to cardiac arrest in their presence and uncover the perceived barriers and facilitators associated with recognizing and treating witnessed OHCAs. ⋯ Recognition and treatment of EMS-witnessed OHCAs are influenced by numerous environmental, crew, and intrapersonal factors. Future training and education on OHCA should include diverse locations, situations, and crew make-up, along with nontraditional patient complaints to broaden experiences associated with cardiac arrest management.

To evaluate the effect of wearing an N95 mask on the quality of chest compression and fatigue of prehospital emergency personnel during cardiopulmonary resuscitation (CPR). ⋯ This study showed that the use of an N95 mask by prehospital emergency personnel during the performance of chest compressions resulted in a reduction of compression quality and increased clinician fatigue. There is a need for CPR training for medical personnel wearing personal protective equipment.

Introduction: While prior research has identified racial disparities in prehospital analgesia for traumatic pain, little is known about non-traumatic pain. Using a national prehospital dataset, we sought to evaluate for racial and ethnic disparities in analgesia given by EMS for non-traumatic pain. Methods: We analyzed the 2018 and 2019 data from the ESO Data Collaborative, a collection of de-identified prehospital electronic health records from nearly 1,300 participating EMS agencies in the US. ⋯ The odds of receiving pain medication within 20 minutes was lower for Black patients (aOR 0.9; 95% CI 0.8-0.95) but no different for Hispanic patients (aOR 1.0; 95% CI 0.9-1.1), when compared to White patients. Conclusion: Pain medication administration is uncommon for non-traumatic pain complaints. While Black patients were less likely than White patients to receive pain medications and receive pain medication within 20 minutes, Hispanics were more likely to receive pain medications.

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.

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.
