#1
S Ångerman, H Kirves, J Nurmi
Results using videolaryngoscopy in pre-hospital rapid sequence intubation are mixed. A bougie is not commonly used with videolaryngoscopy. We hypothesised that using videolaryngoscopy and a bougie as core elements of a standardised protocol that includes a drugs and a laryngoscopy algorithm would result in a high first-pass tracheal intubation success rate. We employed videolaryngoscopy (C-MAC) combined with a bougie (Frova intubating introducer) in an anaesthetist-staffed helicopter emergency medical service...

BACKGROUND: The effect of prehospital helicopter emergency medical services (HEMS) on mortality has been analyzed previously in polytrauma patients with discordant results. OBJECTIVE: Our aim was to compare outcomes in patients with isolated severe blunt traumatic brain injuries (TBIs) transported by HEMS or ground emergency medical services (GEMS). METHODS: We conducted a National Trauma Data Bank study (2007-2014). All adult patients (≥16 years old) who sustained an isolated severe blunt TBI and were transported by HEMS or GEMS were included in the study...

BACKGROUND: Helicopter emergency medical services (HEMS) have demonstrated survival benefits over ground emergency medical services (GEMS) for trauma patient transport. While HEMS speed is often-cited, factors such as provider experience and level of care may also play a role. Our objective was to identify patient groups that may benefit from HEMS even when prehospital time for helicopter utilization is longer than GEMS transport. METHODS: Adult patients transported by HEMS or GEMS from the scene of injury in the Pennsylvania State Trauma Registry were included...

Old-age limits are imposed in some occupations in an effort to ensure public safety. In aviation, the "Age 60 Rule" limits permissible flight operations conducted by pilots aged 60 and over. Using a retrospective cohort design, we assessed this rule's validity by comparing age-related change rates of cardiometabolic incapacitation risk markers in European helicopter emergency medical service (HEMS) pilots near age 60 with those in younger pilots. Specifically, individual clinical, laboratory, and electrocardiogram (ECG)-based risk markers and an overall cardiovascular event risk score were determined from aeromedical examination records of 66 German, Austrian, Polish, and Czech HEMS pilots (average follow-up 8...

BACKGROUND: Prehospital personnel are at risk of occupational hearing loss due to high noise exposure. The aim of the study was to establish an overview of noise exposure during emergency responses in Mobile Emergency Care Units (MECU), ambulances and Helicopter Emergency Medical Services (HEMS). A second objective was to identify any occupational hearing loss amongst prehospital personnel. METHODS: Noise exposure during work in the MECU and HEMS was measured using miniature microphones worn laterally to the auditory canals or within the earmuffs of the helmet...

INTRODUCTION: In the prehospital setting, crystalloid fluids are frequently used, but only erythrocytes are capable of transporting oxygen to tissues. The aim of this study was to establish the efficacy and safety of the prehospital use of uncross matched type O rhesus-negative packed red blood cells (URBC) by the Dutch physician-staffed helicopter emergency medical service. We hypothesized that prehospital URBC transfusions are safe and more effective with respect to survival than resuscitations with crystalloids...

OBJECTIVE: The optimal volume and type of intravenous fluid for the treatment of blood loss in the prehospital setting is controversial. The use of red cell concentrates (RCCs) may be associated with improved outcomes; however, the administration of blood products is limited to physicians in many jurisdictions. We sought to describe the characteristics of RCC transfusions in a paramedic-staffed helicopter emergency medical system in Victoria, Australia. METHODS: We performed a retrospective analysis of all cases where paramedics consulted the responsible physician for approval of RCC transfusion between July 2011 and December 2015 in Victoria, Australia...

BACKGROUND: Deranged glucose metabolism after moderate to severe trauma with either high or low concentrations of blood glucose is associated with poorer outcome. Data on prehospital blood glucose concentrations and trauma are scarce. OBJECTIVES: The primary aim was to describe the relationship between traumatic shock and prehospital blood glucose concentrations. The secondary aim was to determine the additional predictive value of prehospital blood glucose concentration for traumatic shock when compared with vital parameters alone...

Aim: Various critical cases have been transported since the use of the Kanagawa Helicopter Emergency Medical Service (HEMS) started at Tokai University Hospital (Isehara, Japan) in 2002, including cases of acute poisoning. We analyzed the characteristics of acute poisoning cases conveyed by the HEMS. Methods: Kanagawa HEMS conveyed 3,814 cases from July 2002 to March 2013, and acute drug and poison intoxication was diagnosed in 131 of these cases. We undertook a descriptive statistical study of these cases...

Importance: Little evidence exists to guide helicopter emergency medical services (HEMS) triage, and current practice is inefficient. The Air Medical Prehospital Triage (AMPT) score was developed to identify patients most likely to benefit from HEMS compared with ground EMS. To our knowledge, no studies have evaluated the potential effect on costs and outcomes of a more targeted HEMS triage strategy, such as the AMPT score. Objective: To evaluate the cost-effectiveness of current practice compared with the AMPT score for HEMS scene triage of trauma patients...

BACKGROUND: Even in a landlocked country like Switzerland recreational diving is becoming more and more popular. Smaller lakes in the Alps are located at an altitude of 2500 m above sea level. The incidence of diving accidents among all helicopter emergency service missions and the consecutive medical knowledge about decompression injuries is low. Thus, a collaboration between the Swiss Air-Ambulance (Rega) and the divers alert network (DAN) was initiated to improve patient treatment and identification of decompression injury and necessity of hyperbaric oxygen therapy (HBO)...

OBJECTIVE: Reconfiguration of trauma services, with direct transport of patients with traumatic brain injury (TBI) to specialist neuroscience centres (SNCs)-bypassing non-specialist acute hospitals (NSAHs), could improve outcomes. However, delays in stabilisation of airway, breathing and circulation (ABC) may worsen outcomes when compared with selective secondary transfer from nearest NSAH to SNC. We conducted a pilot cluster randomised controlled trial to determine the feasibility and plausibility of bypassing suspected patients with TBI -directly into SNCs-producing a measurable effect...

INTRODUCTION: Implementation of a physician-staffed helicopter emergency medical service (HEMS) in eastern Denmark was associated with increased survival for severely injured patients. This study aimed to assess the potential impact of advanced prehospital interventions by comparing the proportion of patients who received those interventions before and after the HEMS implementation. METHODS: A post-hoc analysis of a prospective before-after study. We included trauma patients with Injury Severity Scores above three who had been admitted to seven emergency departments or one level 1 trauma centre in the course of a five-month period before and a 12-month period after the HEMS implementation...

BACKGROUND: Critically ill patients need to be immediately identified, properly managed, and rapidly transported to definitive care. Extensive prehospital times may increase mortality in selected patient groups. The on-scene time is a part of the prehospital interval that can be decreased, as transport times are determined mostly by the distance to the hospital. Identifying factors that affect on-scene time can improve training, protocols, and decision making. Our objectives were to assess on-scene time in the Helicopter Emergency Medical Service (HEMS) in our region and selected factors that may affect it in specific and severe conditions...

Mountain rescue operations often confront crews with extreme weather conditions. Extremely cold temperatures make standard treatment sometimes difficult or even impossible. It is well-known that most manual tasks, including those involved in mountain rescue operations, are slowed by extremely cold weather. To lessen and improve the decrement in performance of emergency medical treatment caused by cold-induced manual impairment and inadequate medical equipment and supplies, simulation training in a weather chamber, which can produce wind and temperatures up to -22°C, was developed...
