Ashleigh J Delorenzo, Matthew Shepherd, Paul A Jennings
OBJECTIVE: Cuff pressures are important in ventilated patients undergoing helicopter transport. An altitude-related increase in endotracheal tube (ETT) intracuff pressure has been shown in simulated hypobaric environments, model tracheas, and animal studies and may not accurately reflect in vivo pressures. The aim of this study was to determine if ETT intracuff pressure increases above the critical perfusion pressure of the trachea in ventilated patients during helicopter transport. METHODS: Ovid Medline, CINAHL, Embase, Scopus, and the Cochrane Library were searched from their commencement to January 29, 2016...

OBJECTIVE: In Japan, the helicopter emergency medical services (HEMS) system was initiated in 2001 and introduced to Miyazaki Prefecture in 2012. Mountainous areas occupy 88% of Miyazaki's land area, and HEMS flights can be subject to the effects of weather. Therefore, ensuring safety in changing weather conditions is a necessity for HEMS. METHODS: The weather webcam system (WWS) was established to observe the meteorological conditions in 29 locations. Assessments of the probability of a flight based on conventional data including a weather chart provided by the Japan Meteorological Agency and meteorological reports provided by the Miyazaki Airport were compared with the assessment based on the combination of the information obtained from the WWS and the conventional data...

BACKGROUND: The benefits of the Helicopter Emergency Medical Service (HEMS) and dispatch accuracy are continuously debated, and a widely accepted score to measure the benefits of the mission is lacking. The HEMS Benefit Score (HBS) has been used in Finnish helicopter emergency medical services, but studies are lacking. The National Advisory Committee for Aeronautics (NACA) score is widely used to measure the severity of illness or injury in the pre-hospital setting, but it has many critics due to its subjectivity...

BACKGROUND: Helicopter emergency medical services (HEMS) have become an engrained component of trauma systems. In Ontario, transportation for trauma patients is through one of three ways: scene call, modified scene call, or interfacility transfer. We hypothesize that differences exist between these types of transports in both patient demographics and patient outcomes. This study compares the characteristics of patients transported by each of these methods to two level 1 trauma centers and assesses for any impact on morbidity or mortality...

BACKGROUND: Trauma systems in remote and rural regions often rely on helicopter emergency medical services to facilitate access to definitive care. The siting of such resources is key, but often relies on simplistic modeling of coverage, using circular isochrones. Scotland is in the process of implementing a national trauma network, and there have been calls for an expansion of aeromedical retrieval capacity. The aim of this study was to analyze population and area coverage of the current retrieval service configuration, with three aircraft, and a configuration with an additional helicopter, in the North East of Scotland, using a novel methodology...

Health emergency medical service (HEMS) plays an important role in reducing injuries by providing advanced medical care in the shortest time and reducing the transfer time to advanced treatment centers. In the regions without ground relief coverage, it would be faster to transfer emergency patients to the hospital by a helicopter. In this paper, an integer nonlinear programming model is presented for the integrated locating of helicopter stations and helipads by considering uncertainty in demand points. We assume three transfer modes: (1) direct transfer by an ambulance, (2) transfer by an ambulance to a helicopter station and then to the hospital by a helicopter, (3) transfer by an ambulance to a predetermined point and then to the hospital by a helicopter...

BACKGROUND: Survival rates from out-of-hospital cardiac arrest (OHCA) remain low, despite remarkable efforts to improve care. A number of ambulance services in the United Kingdom (UK) have developed prehospital critical care teams (CCTs) which attend critically ill patients, including OHCA. However, current scientific evidence describing CCTs attending OHCA is sparse and research to date has not demonstrated clear benefits from this model of care. METHODS: This prospective, observational study will describe the effect of CCTs on survival from OHCA, when compared to advanced-life-support (ALS), the current standard of prehospital care in the UK...

BACKGROUND: Implementation of a physician-staffed helicopter emergency medical service (PS-HEMS) in Denmark was associated with lower 30-day mortality in severely injured trauma patients and less time on social subsidy. However, the reduced 30-day mortality in severely injured patients might be at the expense of a worse functional outcome and quality of life (QoL) in those who survive. The aim of this study was to investigate the effect of a physician-staffed helicopter on long-term QoL in trauma patients...

BACKGROUND: The Air Medical Prehospital Triage (AMPT) score was developed to identify injured patients who may benefit from scene helicopter emergency medical services (HEMS) transport. External validation using a different data set is essential to ensure reliable performance. The study objective was to validate the effectiveness of the AMPT score to identify patients with a survival benefit from HEMS using the Pennsylvania Trauma Outcomes Study registry. METHODS: Patients 16 years or older undergoing scene HEMS or ground EMS (GEMS) transport in the Pennsylvania Trauma Outcomes Study registry 2000-2013 were included...

The case presented here highlights an unconventional use of a helicopter emergency medical service (HEMS) to provide a specialized medication to a critically ill patient when definitive transport was delayed. A 39-year-old man presented to a rural hospital 1 hour after sustaining a copperhead envenomation. He developed severe symptoms and was intubated. Arrangements were made for transfer to a tertiary referral center by HEMS, but because of incoming weather conditions, the team would not be able to make the return flight safely...
