Linda Sandström, Carina Nilsson, Päivi Juuso, Åsa Engström
INTRODUCTION: When emergency medical services (EMS) are needed, the choice of transport depends on several factors. These may include the patient's medical condition, transport accessibility to the accident site and the receiving hospital's resources. Emergency care research is advancing, but little is known about the patient's perspective of helicopter emergency medical services (HEMS). AIM: The aim of this study was to describe trauma patients' experiences of HEMS...

OBJECTIVE: Safety in helicopter emergency medical services (HEMS) settings might be enhanced by the routine use of portable multigas analyzers to indicate hypoxic ambient air mixtures and the presence of hazardous gases. METHODS: In our HEMS (EC-135, Lifeliner 1, Amsterdam, The Netherlands), we introduced a professional multigas analyzer (Gas Alert Max XT II; Honeywell Analytics, Lincolnshire, IL) to prospectively detect possible hazardous gas mixtures. This analyzer measures ambient oxygen percentage (FO2, 0%-30%), carbon monoxide (CO, 0-1,000 ppm), hydrogen sulfide (H2S, 0-200 ppm), and combustibles (lower explosive limit, %)...

PURPOSE: Many changes have been made to improve trauma care. Improved trauma team response and usage of a hybrid resuscitation room are examples of how this trauma center has developed. The aim was to assess how the outcome of the trauma population was influenced by the maturation. METHODS: A cohort comparison, between June 2004-July 2005 and 2014, was performed. All adult trauma patients with an Injury Severity Score (ISS) >15 were included. Variables collected were: patient demographics, mechanism of trauma, total prehospital time, pre- and inhospital trauma scores, vital signs, blood values and interventions, and physician staffed helicopter emergency medical services (P-HEMS) involvement and outcome...

Critical care transport (CCT) teams are specialized transport services, comprised of highly trained paramedics, nurses, and occasionally respiratory therapists, offering an expanded scope of practice beyond advanced life support (ALS) emergency medical service teams. We report 4 cases of patients with severe acute respiratory distress syndrome from influenza in need of extracorporeal membrane oxygenation evaluation at a tertiary care center, transported by ground. Our medical center did not previously have a ground CCT service, and therefore, in these cases, a physician and/or a respiratory therapist was sent with the paramedic team...

BACKGROUND: Search and rescue (SAR) operations constitute a significant proportion of Norwegian ambulance helicopter missions, and they may limit the service's capacity for medical operations. We compared the relative contribution of the different helicopter resources using a common definition of SAR-operation in order to investigate how the SAR workload had changed over the last years. METHODS: We searched the mission databases at the relevant SAR and helicopter emergency medical service (HEMS) bases and the Joint Rescue Coordination Centre (North) for helicopter-supported SAR operations within the potential operation area of the Tromsø HEMS base in 2000-2010...

BACKGROUND: Severely injured children may have better outcomes when transported directly to a Paediatric Trauma Centre (PTC). A case identification system using the crew of a physician staffed helicopter emergency medical service (P-HEMS) that identified severely injured children for P-HEMS dispatch was previously associated with high rates of direct transfer. It was theorised that discontinuation of this system may have resulted in deterioration of system performance. METHODS: Severe paediatric trauma cases were identified from a state based trauma registry over two time periods...

OBJECTIVE: Transportation by air exposes drugs used in emergency medical services to vibrations. The aim of the study was to determine whether or not vibrations caused by a helicopter induce the degradation of 5 drugs used in this setting. METHODS: A longitudinal study in an operating medical helicopter along with a worst case was conducted. The studied drugs were 3 drugs labeled for refrigeration (cisatracurium, lorazepam, and succinylcholine) and 2 albumin solutions (human albumin 4% and 20%)...

BACKGROUND: The use of helicopter emergency medical services (HEMS) has increased significantly in the UK since 1987. To date there has been no research that addresses HEMS pilots and medical crews' own ideas on the risks that they view as inherent in their line of work and how to mitigate these risks. The aim of this survey is to describe and compare the attitudes and perceptions towards risk in HEMS operations of these staff. METHODS: A questionnaire was administered electronically to a representative selection of HEMS doctors, paramedics and pilots in the UK...

OBJECTIVE: Drowning is one of the leading injury death causes in younger children. Common intensive care measures seem not to improve neurologic outcome, and early prognostic options appear partially unreliable. Therefore, we evaluated a cohort of drowning patients cotreated by a helicopter emergency medical service regarding typical incident constellations, early and subsequent prognostic options, and relevant interventions. METHODS: All patients prehospitally cotreated by helicopter emergency medical service "Christoph 4" in primary missions because of drowning incidents during a 10-year period were evaluated...

INTRODUCTION: Airway management in the out-of-hospital emergency setting is challenging. Failed and even prolonged airway management is associated with serious clinical consequences, such as desaturation, bradycardia, airway injuries, or aspiration. The overall success rate of tracheal intubation ranges between 77% and 99%, depending on the level of experience of the provider. Therefore, advanced airway management should only be performed by highly-skilled and experienced providers. METHODS: 9765 patients were treated in the out-of-hospital emergency setting by the anaesthesiologist-staffed Helicopter Emergency Medical Services (HEMS) between 2002 and 2014...

INTRODUCTION: In the United States, accident and fatality rates in helicopter emergency medical service (HEMS) operations increase significantly under nighttime environmentally hazardous operational conditions. Other studies have found pilots' total flight hours unrelated to HEMS accident outcomes. Many factors affect pilots' decision making, including their experience. This study seeks to investigate whether pilot domain task experience (DTE) in HEMS plays a role against likelihood of accidents at night when hazardous operational conditions are entered...
