Review Meta Analysis
Prehospital continuous positive airway pressure for acute respiratory failure: a systematic review and meta-analysis.
Acute respiratory failure (ARF) is a common problem encountered by emergency medical services and is associated with significant morbidity, mortality, and health care costs. Continuous positive airway pressure (CPAP) is an integral part of the hospital treatment of acute ARF, predominantly because of congestive heart failure. Intuitively, better patient outcomes may be achieved when CPAP is applied early in the prehospital setting, but there are few outcome studies to validate its use in this setting. ⋯ The studies included in this review showed a reduction in the number of intubations and mortality in patients with ARF who received CPAP in the prehospital setting. The results may not be applicable to other health care contexts because of the inherent differences in the organization and staffing of the EMS systems. Information from large RCTs on the efficacy of CPAP initiated early in the prehospital setting is critical to establishing the evidence base underpinning this therapy before ambulance services incorporate CPAP as routine clinical practice.

Review Case Reports
Successful administration of intranasal glucagon in the out-of-hospital environment.
We present a case of successful prehospital treatment of hypoglycemia with intranasal (IN) glucagon. Episodes of hypoglycemia can be of varying severity and often requires quick reversal to prevent alteration in mental status or hypoglycemic coma. Glucagon has been shown to be as effective as glucose for the treatment of hypoglycemia. ⋯ Intranasal administration of glucagon has been shown to be as effective as the IV route and may be used for rapid correction of hypoglycemic episodes where IV access is difficult or unavailable and IM administration is undesirable. We describe the first documentation in the peer-reviewed literature of the successful treatment and reversal of an insulin-induced hypoglycemic episode with IN glucagon in the prehospital setting. We also present a review of the literature regarding this novel medication administration route.

Preventable harm from medical care has been extensively documented in the inpatient setting. Emergency medical services (EMS) providers care for patients in dynamic and challenging environments; prehospital emergency care is a field that represents an area of high risk for errors and harm, but has received relatively little attention in the patient safety literature. ⋯ We found a paucity of scientific literature exploring patient safety in EMS. Research is needed to improve our understanding of problem magnitude and threats to patient safety and to guide interventions.

Abstract The out-of-hospital setting is unique to health care and presents many challenges to providing safe, high-quality medical care in emergency situations. The challenges of the prehospital environment require thoughtful design of systems and processes of care. The unique challenges of ambulance safety may be met by analyzing systems and incorporating process improvements. ⋯ The agent of injury refers to the energy exerted during the course of an injury, and may be modified to include unrestrained equipment that contributes to the injury. The physical environment refers to the characteristics of the setting in which the injury takes place, such as the roadway or the physical design of the ambulance. Finally, the social environment refers to the social, legal, and cultural norms and practices in the society, such as peer pressure and a culture that discourages the use of safety equipment.

In the development of an emergency medical services (EMS) system, medical directors should consider the implementation of protocols for the termination of resuscitation (TOR) of nontraumatic cardiopulmonary arrest. Such protocols have the potential to decrease unnecessary use of warning lights and sirens and save valuable public health resources. ⋯ Further research is needed to determine the need for direct medical oversight in TOR protocols and the duration of resuscitation prior to EMS providers' determining that ROSC will not be achieved. This paper is the resource document to the National Association of EMS Physicians position statement on the termination of resuscitation for nontraumatic cardiopulmonary arrest.
