Operational medicine overview Tactical Combat Casualty Care SSG Kile Ninety percent of combat wound fatalities die on the battlefield before reaching a medical treatment facility. This fact of war emphasizes the need for continued improvement in combat prehospital care. Trauma care training for military medics has been based primarily on the principles taught in the Advanced Trauma Life Support (ATLS) course. ATLS provides a standardized approach to the management of trauma that has proven very successful when used in the setting of a hospital emergency department. The value of at least some aspects of ATLS in the prehospital setting, however, has been questioned, even in the civilian sector. Military authors have voiced additional concerns about the applicability of ATLS in the combat setting. Mitigating factors such as darkness, hostile fire, resource limitations,

prolonged evacuation times, unique battlefield casualty transportation issues, command and tactical decisions affecting healthcare, hostile environments, and provider experience levels pose constraints different from the hospital emergency department. These differences are profound, and must be carefully reviewed when trauma management strategies are modified for combat application. references Operational Emergency Medical Skills Course Manual, LTC (Ret) J.

Medicine, Vol. 161, Supp 1, 1996 3 environments for care HOSPITALS TRADITIONAL PRE-HOSPITAL CARE OPERATIONAL OUT-OFHOSPITAL MEDICAL SUPPORT HOSPITALS Primarily deals with blunt trauma Access to full range of specialist Physicians

Resource intensive Advanced trauma care facilities, Intensive care units ATLS procedures Pre-surgical evaluation with access to full labs, blood banks, etc. TRADITIONAL PREHOSPITAL CARE Primarily deals with blunt trauma Rapid response times Well equipped and supported, utilizes EMT trained personnel Advanced life support capabilities Rapid transport and access to ambulances, helicopters, etc. Short evacuation times (usually less than 1 hour away

from hospital) Strict medical control and use of protocols OPERATIONAL OUTOF-HOSPITAL MEDICAL SUPPORT Most significant difference between this and the above are evacuation times of greater than 1 hour Primarily deals with penetrating trauma Independent providers Austere environments Echeloned care May have delayed initial medical access (scene safety important) In most cases limited to what medic can carry in aid-bag Often pre-injury stressor is present (e.g. dehydration, sleep

deprivation, stress of mission) Operational field care 3 distinct areas Care Under Fire Tactical Field Care Combat Casualty Evacuation Care CASEVAC Care under fire

Dressings, Splints and Meds CPR - Resuscitation on the battlefield for victims of blast or penetrating trauma who have no pulse, no respirations, and no other signs of life will not be successful and should not be attempted. C-spine precautions C-spine control: even with the neck supported in a C-collar, you do not prevent all neck injury For penetrating trauma, C-spine control is unnecessary (blunt trauma tears vertebral ligaments requiring support). Penetrating injury blasts away ligaments, so if there is penetrating trauma then you already have C-spine trauma Value no one has shown conclusively that C-spine control can reduce the number of people who become paralyzed. For example, in Austria, an EMS system was established in the 1980s using C-spine control but no

differences were detected in numbers of patients who developed paralysis before and after introduction (does not mean it isnt there). C-spine control tends to be very resource intensive (manpower and medical management) that we do not use it except for very specific injuries where you think that there is a C-spine injury. Standard medical procedures have been developed for the treatment of patients in the traditional prehospital and hospital environments where evacuations are usually achieved in less than 1 hour. These procedures are not always applicable to your work environment. UNDERSTAND THE ENVIRONMENT YOU ARE WORKING IN!! Mortality curve Following trauma, the chances of a casualty

surviving are dependant upon numerous variables, including the speed at which appropriate medical treatment is administered. During this discussion, we will look at the factors that can affect the chances of a casualty surviving as injury symptoms developing from initial penetrating trauma, through hemorrhage and/or respiratory compromise, to shock and infection. Mortality curve penetrating trauma Instantaneous Death 100% Breathing complications

Shock is initially a physiological protection response that occurs in response to injury Not a state your body slowly goes into because of injury Stages Compensated Decompensated Irreversible Conclusion Operational Environment is different from civilian pre-hospital environment.
