Background: Critical illness requires specialist and timely management. The aim of this study was to create a geographic accessibility profile of the Scottish population to emergency departments and intensive care units. Methods: This was a descriptive, geographical analysis of population access to 'intermediate' and 'definitive' critical care services in Scotland. Access was defined by the number of people able to reach services within 45 to 60 min, by road and by helicopter...

INTRODUCTION: Prehospital airway management of the paediatric patient with traumatic brain injury (TBI) is controversial. Endotracheal intubation of children in the field requires specific skills and has potential benefits but also carries potentially serious complications. We aimed to compare mortality and functional outcomes after six months between children with TBI who either underwent prehospital rapid sequence intubation (RSI) by trained Intensive Care paramedics (ICP) or received no intubation...

Controllers and pilots must work together to ensure safe and efficient helicopter flight within the London control zone. Subjective ratings of pilot perception of controller responsibility for five key flight tasks were obtained from thirty helicopter pilots. Three types of airspace were investigated. Results indicate that there is variation in pilot understanding of controller responsibility compared to the formal regulations that define controller responsibility. Significant differences in the perception of controller responsibility were found for the task of aircraft separation in class D airspace and along helicopter routes...

S P Sadala, B M Patre
The 2-degree of freedom (DOF) helicopter system is a typical higher-order, multi-variable, nonlinear and strong coupled control system. The helicopter dynamics also includes parametric uncertainties and is subject to unknown external disturbances. Such complicated system requires designing a sophisticated control algorithm that can handle these difficulties. This paper presents a new robust control algorithm which is a combination of two continuous control techniques, composite nonlinear feedback (CNF) and super-twisting control (STC) methods...

Trajectory tracking control for helicopters, which are widely used in severe situations such as military and rescue missions, is a challenging field of research. In helicopter system, the stability problem and predefined trajectories tracking are main challenges, especially in the presence of external disturbances and dynamic model uncertainties. Hence, a robust control design is needed for tracking the desired references. There has been a lot of motivation for solving these problems with simpler methods and also reducing the couplings in the helicopter system to achieve better performance, as the presented paper attempts to fill these gaps...

BACKGROUND: Major incidents affect us globally, and are occurring with increasing frequency. There is still no evidence-based standard regarding the best medical emergency response to major incidents. Currently, reports on major incidents are non-standardised and variable in quality. This pilot study examines the first systematic reports from a consensus-based, freely accessible database, aiming to identify how descriptive analysis of reports submitted to this database can be used to improve the major incident response...

Trimethylsilyl ethers of 1,5-diaryl-3-(trifluoromethyl)pent-1-en-4-yn-3-oles in superacid CF3SO3H (TfOH) give rise to the corresponding intermediate CF3-pentenynyl cations. These species react with benzene to afford conjugated CF3-pentenynes, which undergo subsequent cyclization, first, into CF3-cycloheptadienes and, finally, into unusual CF3-"helicopter"-like bicyclic structures.

Helicopter Emergency Medical Services (HEMS) is presumably an effective way of patient transport in rural trauma, yet the literature addressing its effectiveness is scarce. In this study, we compared the clinical outcome of rural trauma patients between Ground Emergency Medical Services (GEMS) and HEMS transportation from the beginning of 2006 to the end of 2012. Focus was placed on identifying factors associated with survival to discharge in these patients. Over the seven-year study period, 4492 patients met the inclusion criteria with 2414 patients (54%) being transferred by GEMS and 2078 patients (46%) being transferred by HEMS...

OBJECTIVE: Airway management is a requisite skill set for helicopter emergency medical service (HEMS) providers. Cricothyrotomy is a potentially lifesaving skill that is used when other airway maneuvers fail. The authors reviewed all transports by a helicopter program in which cricothyrotomy was performed to assess the frequency, success, and technique. METHODS: This was a retrospective chart review of air medical patient records from an electronic medical record system over a 112-month period...

OBJECTIVE: The competence, composition, and number of crewmembers have generally been considered to influence the degree of patient care and safety in helicopter emergency medical services (HEMS), but evidence to support the advantages of one crew concept over another is ambiguous; additionally, the benefit of physicians as crewmembers is still highly debated. METHODS: To compare perceived safety in different medical crew models, we surveyed international HEMS medical directors regarding the types of crew compositions their system currently used and their supportive rationales and to evaluate patient and flight safety within their services...

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...
