Routine continuous monitoring of endotracheal tube placement with waveform capnography is considered standard of care in the prehospital setting. However, maintaining this standard in neonatal patients remains a challenge due to low tidal volumes that do not tolerate the additional dead space ETCO2 attachments add. Additionally, continuous ETCO2 can increase the risk of ETT dislodgement or kinking because of the weight and size of the capnography attachments relative to the patient and tube size. We hypothesize that there is a gap in care of intubated neonates when compared to adults in the prehospital setting in terms of continuous monitoring of ETT placement. ⋯ Continuous ETCO2 monitoring is underutilized in intubated neonates compared to children, adolescents, and adults in the prehospital setting in this study population. This suggests a gap in the standard of care provided to neonates. Additional studies are needed to determine if these results are consistent around the industry and if there is a higher rate of undetected tube displacement in neonates who are transported without waveform capnography.

First medical contact for patients with sepsis often initiates in the prehospital setting, yet limited studies have explored the EMS sepsis recognition-mortality relationship. Racial and ethnic minority patients often have worse sepsis outcomes, yet the role of prehospital recognition in this inequity has not been explored. Our objective was to describe prehospital sepsis recognition and hospital mortality, with analysis by patient race and ethnicity. ⋯ EMS identified sepsis in fewer than one in three patients even after limiting to those positive for qSOFA, without differences by race and ethnicity. EMS sepsis recognition was associated with reduced odds of mortality; however, Black patients remained at greater odds of death suggesting additional factors that warrant investigation.

The Assessment of Blood Consumption (ABC) score is a previously validated scoring system designed to predict which severely injured trauma patients will require massive transfusion. When the ABC score is used in the prehospital setting to activate massive transfusion at the receiving hospital, a 23% decrease in mortality has been demonstrated. However, the ABC score was developed and validated using hospital data from the emergency department (ED). The sensitivity and specificity of the ABC score when calculated using data from the prehospital setting are unknown. We hypothesized that the sensitivity and specificity of the prehospital ABC score will be similar to the sensitivity and specificity of the ED ABC score. ⋯ The ABC score is a useful prehospital tool for identifying who will require massive transfusion. Future studies to evaluate the effect of the prehospital ABC score on clinical care and mortality are necessary.

Prehospital obstetric events, including out-of-hospital deliveries and their complications, are a rare but high-risk event encountered by emergency medical services (EMS). Understanding the epidemiology of these encounters would help identify strategies to improve prehospital obstetric care. Our objective was to determine the characteristics of out-of-hospital deliveries and high-risk complications treated by EMS clinicians in the U.S. ⋯ In this large, national repository of EMS patient care records from across the U.S., most activations for out-of-hospital delivery, delivery complication, or a newborn included only routine EMS care. There were potential disparities in level of care, clinical care provided, and measures of access to definitive care based on maternal and community factors. We also identified gaps in current practice, such as for postpartum hemorrhage, that could be addressed with changes in EMS clinical protocols and regulations.

Case Reports
18-Month-Old with Lethargy and Accelerated Idioventricular Rhythm in Prehospital Setting: A Case Report.
We report a case of accelerated idioventricular rhythm (AIVR) identified by Emergency Medical Services (EMS) monitoring of an infant presenting with lethargy and respiratory distress. Accelerated idioventricular rhythms are rare ventricular rhythms originating from the His-Purkinje system or ventricular myocytes, consisting of >3 monomorphic beats with gradual onset and termination.1 An AIVR is usually well-tolerated and does not require treatment, though sustained arrythmia may induce syncope, and the rhythm has been seen in newborn infants with congenital heart diseases.1 Monitoring ill children with ECG can identify such dysrhythmias in the prehospital setting. ⋯ Accelerated idioventricular rhythm is relatively rare entity without underlying cardiac disease and most cases are asymptomatic or benign. In the pediatric population, AIVR is generally related to congenital heart defects, cardiac tumors, and cardiomyopathies. In the prehospital setting, continuous ECG monitoring should be a part of care by Advanced Life Support personnel in children with altered mental status, respiratory distress, unexplained syncope, or suspected arrhythmias and 12 lead ECG should be considered if there is any abnormality noted. While this patient did not experience persisting morbidity from AIVR, the potentially hazardous rhythm would not have been recognized without the astute observation, clinical management and persistent follow up of the prehospital clinicians.
