We aimed to quantify the number of prehospital randomized controlled trials (RCTs) published in the 25 years since the Callaham editorial and review his perception of prehospital emergency care as "scanty" science. ⋯ In the time period reported by Callaham, the average number of prehospital RCTs was 4.5 per year. The number of prehospital RCTs published per year has increased only slightly, to 5.6 per year, in the 25 years since Callaham described prehospital emergency care as a "scanty science."

Transcutaneous cardiac pacing (TCP) is a potentially lifesaving therapy for patients who present in the prehospital setting with bradycardia that is causing hemodynamic compromise. Our objective was to examine the outcomes of patients who received prehospital TCP and identify predictors of TCP failure. ⋯ Patients who undergo prehospital TCP are at high risk of mortality. Progression to cardiac arrest is common and associated with factors including increased weight, a non-bradycardic initial heart rate and pre-TCP hypoxia.

ST-elevation myocardial infarction (STEMI) is an Acute Myocardial Infarction (AMI) with the greatest risk of death and disability. Getting diagnosed patients rapid definitive treatment at the correct facility is crucial in improving their outcome. Using a Question-and-Answer algorithm (Mobile Priority Dispatch System (MPDS®)), trained Emergency Medical Dispatchers (EMDs) can help identifying STEMI at the time of dispatch. This can assist Emergency Medical Services (EMS) pre-planning transport to potential STEMI-receiving hospitals. The study aimed to determine whether hospital-confirmed STEMI cases transported by ambulance are associated with certain dispatch determinant codes and identify the treatments performed. ⋯ Qatar's STEMI patients are more likely to be male and to receive adequate acute care irrespective of any demographic factor and despite potential language issues. This study highlights that the chief complaint may be described or interpreted differently when the questioning language is not their mother tongue, or when there is a language barrier between the caller, call taker, or when using the MPDS® protocols language or when self-translating questions instantly in another language. Therefore, EMDs should be made aware of the language differences and be encouraged to further clarify the chief complaint when appropriate. There may be a need for potential refinements of the MPDS® questioning algorithm and EMD training with AMI symptoms reinforcement. This could help improve their early identification of STEMI cases with non-classic chest pain symptoms.

Although the proximal tibia is a common site for intraosseous (IO) line placement in pediatric patients, previously published data indicate high malposition rates in infants and children at this location. Although distal femur IO lines generally demonstrate higher flow rates than those at the proximal tibia, to date, there have been no published studies assessing distal femur IO access in pediatric patients. Thus, we aimed to compare the success rates of pediatric IO line insertion attempts between the proximal tibia and the distal femur in a prehospital setting. ⋯ This retrospective analysis of pediatric patients in a prehospital setting suggests that IO line placement at the distal femur might offer a marginally higher success rate compared to the proximal tibia. Despite not reaching statistical significance, these findings support the consideration of distal femur as a viable option for IO placement in the pediatric population.
