Specificities of Surgery inTime of Armed Conflict orNatural Disaster Christos Giannou Advanced Course in the Management of Disaster Victims Nicosia, October 2011
Natural disaster, accident, isolated explosionOne-off event:surprise, warning WarSuccessive events: NO surprise, political build-up
Rights and obligations of Medical Personnel • Specific epidemiology of war (constant) / disaster (variable) • Predominance of emergency surgery (especially during early tactical field care) • Surgery within a limited technical environment • Limits of surgery: post-operative nursing + anaesthesia • Surgery in a hostile, violent environment
Mass casualties involving the principles of triage • Surgery and triage in successive echelons (delayed evacuation) • Specific wound pathology, qualitatively different from civilian wounds: ballistics & blast; all are dirty and contaminated • Specific techniques appropriate to the context and pathology: simplicity, security, speed • Importance of disease: disease is four times more common than trauma among soldiers; disaster public health approach

Medical Ethics Oath of Hippocrates: International Code of Medical Ethics: WMA 1949 London, 2006 Pilanesberg S. Africa
International Humanitarian Law: laws of war • Geneva Conventions 1949 • Additional Protocol I 1977
Rights and obligations of International Humanitarian Law: laws of war • Specific epidemiology of war (constant) / disaster (variable) • Predominance of emergency surgery • Surgery within a limited technical environment • Limits of surgery: post-operative nursing + anaesthesia • Surgery in a hostile, violent environment
War wounded in the field: epidemiology WW in the field (GSW, mine, blast) 100 wounded 40-60 % 40-60 % No surgery Hospital care First Aid 90% Surgery 10% NO Surgery Dressing 10-15% Head Small wounds 10-12% Chest Paraplegia Tetraplegia 8-10% Abdomen 60-70% Limbs Observation
War wounded: causes of death • Severe injury (brain, major vessels) • Haemorrhage: peripheral • Airway, breathing • Coagulopathy, acidosis, hypothermia / multiple system failure
Natural disaster: context • Earthquake • demographic density • type of construction • access: rural or urban • Tsunami • Storm / flooding • Neighbourhood nuclear plant
Epidemiology of disaster wounded:collapse of 8-storey building China • 80% of entrapped died immediately or early • 10% survived with minor injuries • 10% severe injuries • of which 70% developed crush syndrome
Earthquake Survival Rate:% survivors still alive without extraction
Earthquake: causes of death • Immediate: severe crush of head or thorax (organ damage + suffocation) • Early: ABC • Delayed: dehydration, hypothermia • Late: crush syndrome (acute renal failure), sepsis, multiple organ failure
Rights and obligations of International Humanitarian Law: laws of war • Specific epidemiology of war (constant) / disaster (variable) • Predominance of emergency surgery • Surgery within a limited technical environment • Limits of surgery: post-operative nursing + anaesthesia • Surgery in a hostile, violent environment
Specificities of austere environments • Damaged infrastructure (water, electricity) • Lack of experienced human resources: competency, fatigue, fear • Lack of equipment and supplies: appropriate • Lack of blood for transfusion • "Humanitarian circus" and military-civilian cooperation • Culture shock
Understanding the limits • simplicity of diagnostic means available • laboratory: Hb/Hct, blood grouping & screening • anaesthesia (local, regional, ketamine) • availability of blood (no components): autotransfusion • patient monitoring (BP, P, O2 saturation) • post-operative nursing care Heroic surgery will never replace good surgery.
Clinical skills • Lucky if you have X-rays • Chest tube & laparotomy on clinical basis alone (no DPL) • No place for CPR, ER thoracotomy • Limited- or non- use of endotracheal intubation, no mechanical ventilation • Proper indications and use of damage control techniques • Will you see your patient again? • Category IV? supportive treatment
Always plan for alternatives: • infrastructure • equipment • communications • supplies, logistics • human resources

Mass casualties involving the principles of triage • Surgery and triage in successive echelons (delayed evacuation) • Specific wound pathology, qualitatively different from civilian wounds: ballistics & blast; all are dirty and contaminated • Specific techniques appropriate to the context and pathology: simplicity, security, speed • Importance of disease: disease is four times more common than trauma among soldiers; disaster public health approach

Old lessons for new surgeons War / disaster wounds are dirty and contaminated, from the moment of injury.The rules of septic surgery apply.
Principles of septic surgery The best antibiotic is good surgery.
