20.7 Definitions Suggested medical escort flight time limitations • duty time • period between arrival at base office for briefing and collection of equipment, and arrival at destination hotel for first rest (that is, after seeing patient, if applicable) • minimum rest time • minimum time between arrival and departure from the patient’s location this period should not include time spent traveling to or attending the patient, nor the transfer of the patient to the airport optimum minimum rest time • 1.5 x the previous duty time plus one hour for every time zone crossed Flexibility • in the interests of economy, if the next available flight departs more than 12 hours after the end of the minimum rest time, or involves an extra overnight stop, the minimum rest time can be reduced

clearly, there is no single answer for all situations, and a few examples will highlight the difficulties: in some geographic locations and under some circumstances, the environment and availability of assets dictate the answer For instance, when search and rescue helicopters are utilized to retrieve casualties from mountains, moors or the sea in most cases the survivor is rescued from a hostile environment and, although limited medical care may be possible onboard the helicopter, little or nothing can be done at the scene At the roadside, in the single casualty situation, if a road ambulance is on scene within a few minutes and the nearest emergency room is nearby, although much could be done for the patient, with appropriate facilities so close, speedy evacuation is warranted and only the essentials should be attempted If entrapment delays evacuation, one must ask how serious are the injuries, and will the patient survive the extrication process without the provision of advanced resuscitation skills? Resuscitation and stabilization on scene may be essential in these cases, but it should not unnecessarily delay extraction the caveat is, of course, that the extrication process, itself, must not prevent urgent medical actions in a multicasualty situation, other ambulances will be required and the surrounding roads may be congested as a result of the accident the nearest hospital may not have the required specialist facilities, such as burns, neurosurgery and cardiothoracic surgery The questions then to ask are: who needs to be evacuated immediately, and to where? Who can be retained, and why? Care must be taken to avoid a bottleneck at the nearest emergency room, thereby delaying definitive care for those in most need Who should provide immediate medical care? Ambulance technicians are familiar with roadside scenarios and, although trained and equipped paramedics quite clearly influence the survival and outcome of many casualties, they are still limited by the extent of their skills At the other end of the scale, most hospital doctors, without proper training in prehospital management, work best in a familiar environment, with familiar equipment, and with the teamwork and support services that are normally provided in a hospital Immediate care trained doctors, whether community or hospital-based, are likely to be able to cope with most incidents, even more so if they have anesthetic and Primary Transfers – The Casualty Evacuation Conflict 281 surgical skills Many family practitioners are now vastly experienced in the roadside management of serious injuries They work closely alongside their paramedic colleagues, supporting, supplementing and supervising their medical capabilities in complicated and multiple trauma situations some hospitals are now able to provide mobile medical teams (previously known as ‘accident flying squads’) for complicated incidents in general, these teams will have been trained and equipped for the prehospital environment and will have suitable transport and communications to act independently, yet under the control of the medical incident officer at the scene When evacuation of many casualties is needed, decisions must also be made about the most suitable mode or methods of transport perhaps by using road ambulances, buses or trucks, by rail or underground, by sea or by air However, the old adage that ‘evacuation is important but resuscitation is a priority’ is still true Every medical student knows that shocked patients travel poorly In fact, any patient who has an unstable airway, breathing or circulation undertakes a perilous journey when he is scooped away from the scene of injury Although speed is important in transferring critically injured patients from the incident to hospital, it is secondary to safety and ongoing management of life threatening conditions When faced with a delay in evacuation or a journey lasting more than a few minutes, each patient should preferably be stabilized and ‘packaged’ appropriately for a safe transfer Monitoring and continual reappraisal during transportation is essential it is now common to see military and civilian helicopters at the sites of major accidents and disasters At incidents on or near airports, it should be remembered that fixed wing aircraft can be used to transfer patients over long distances, although this mode of transfer is usually utilized for secondary or tertiary referrals, and for repatriation from overseas after life-saving treatment has been completed often a mixture of ground and air ambulances is required, and it should be remembered that helicopters can be used to bring skills and equipment to the accident scene in addition to taking patients away from it For small contained incidents, though, the helicopter can usefully be utilized as a mobile intensive care unit, thereby extending the therapeutic arm of the hospital into the community So, having started with a grand aim – to resolve the casualty evacuation conflict – the situation is perhaps now more confused by the illustration of the many pitfalls that may be encountered ideally, the aim is to provide the best possible care for those patients with greatest need However, to ensure the maximum benefit to the largest number, triage must be used, and it must be performed by the most experienced resuscitation trained person on site (not always a doctor) triage will not only decide the priorities of treatment, but also the priority for evacuation, since the patient with an unresolved airway problem (A) is likely to die before the patient with a breathing problem (B) who, in turn, is likely to die before the patient with a circulatory problem (c), and so on triage is essentially a dynamic process casualties must be continually reassessed and priorities must be changed in the light of clinical deterioration or improvement Aeromedical Transportation: A Clinical Guide 282 And so to the decision-making process The essential point is that there is no single, simple, universal answer decisions must be made by the person in control at the scene if that person is not aware of the extent of the incident (and that may not be easy in the early minutes or hours of a significant catastrophe), or if he is not in communication with those at the workface, any decisions made will be based on an inappropriate model of events there is no authoritative advice, but the aim must always be to treat those who are salvageable, and in most urgent need, first Delay in definitive care will cost lives If nearby hospitals are blocked by an early wave of minor injuries and these hospitals are unaware of the extent of the backlog still to come, those in most need will die waiting for attention Table 21.1 lists the information which is therefore essential before making decisions on which casualties should be held, which should be stabilized, which should be evacuated first, and of course, by which means Although there are no easy answers, it is essential, at least, to be aware of the potential problems If all else fails, ask yourself ‘where is the potential medical bottleneck going to be and what can I to prevent it?’ Table 21.1 • • • • • • • • • • • • • • • • • Considerations in casualty evacuation number of casualties numbers in each triage group Will there be delays in extrication?
