MARCH Home Knowledge on Blast Injuries
Under the best of situations major trauma centers can be overwhelmed with dozens of seriously injured patients but for many CMES participants limited resources are an everyday reality. The August EM:RAP podcast titled, “Blast Injuries” by Anand Swaminathan MD and Josh Bucher MD will help you piece together triage and treatments for a mass casualty.
Tactical Combat Casualty Care (TCCC) uses the mnemonic MARCH for military battlefield medicine.
- Massive hemorrhage is managed through the use of tourniquets, hemostatic dressings, junctional devices, and pressure dressings.
- Airway is managed by rapid and aggressive opening of the airway to include cricothyroidotomy for difficult airways.
- Respirations and breathing is managed by the assessment for tension pneumothorax and aggressive use of needle decompression devices to relieve tension and improve breathing.
- Circulation impairment is assessed and managed through the initiation of intravenous access followed up by administration of tranexamic acid (TXA) if indicated, and a fluid resuscitation challenge using the principles of hypotensive resuscitation. TCCC promotes the early and far forward use of blood and blood products if available over the use colloids and discourages the administration of crystalloids such as normal saline (sodium chloride).
- Hypothermia prevention is an early and critical intervention to keep a traumatized casualty warm regardless of the operational environment.
