Life-Saving Protocols in Tactical Medicine: Understanding MARCH and MIST
Introduction
In the unpredictable and high-stakes realm of tactical medicine, the difference between life and death often hinges on the proficiency and speed of medical response. The MARCH protocol and the MIST report are not mere acronyms; they are lifelines in the chaos of battlefield and emergency medicine. These frameworks guide military medics, Special Forces, and first responders through the complexities of medical emergencies, ensuring systematic application of life-saving measures and accurate communication of critical patient information.
Section 1: The MARCH Protocol
Massive Hemorrhage
Massive hemorrhage is the leading cause of preventable death in tactical situations. It is crucial to control severe bleeding as soon as possible. The first step in treating massive hemorrhage is to apply direct pressure to the wound. If direct pressure does not work, then a tourniquet may be necessary to stop the bleeding. Tourniquets have been proven to be effective in stopping severe bleeding in the extremities. It is important to remember that tourniquets should only be applied as a last resort and should be removed as soon as possible to prevent tissue damage.
What to Look For: Signs of life-threatening bleeding, such as blood spurting from a wound, pooling blood, loss of limb, or wounds in the junctional areas (groin, armpits, neck).
Indications for Treatment: Active, severe bleeding; amputation; penetrating trauma.
Contraindications: Avoid applying tourniquets on the neck and over solid objects in the wound. Caution with prolonged application to prevent tissue damage.
Airway
The second step in the MARCH protocol is to assess and manage the airway. In a tactical situation, there may be a high risk of airway obstruction due to trauma, blood, or vomit. It is essential to maintain a clear airway to prevent hypoxia and ensure adequate oxygenation. Airway management can range from simple maneuvers like head-tilt chin-lift to more advanced techniques like intubation or cricothyrotomy. The airway management technique chosen should be appropriate for the patient's condition and the available resources.
What to Look For: Signs of airway obstruction like difficulty speaking, abnormal breathing sounds, visible blockages in the mouth or throat.
Indications for Treatment: Inability to maintain airway patency, severe facial trauma, unconsciousness.
Contraindications: Avoid blind finger sweeps in the mouth; use caution with cervical spine injuries when performing head-tilt chin-lift maneuvers.
Respiration
The third step is to assess and manage breathing. In a tactical situation, respiratory compromise can occur due to a variety of causes like chest trauma, pneumothorax, or airway obstruction. It is essential to assess the breathing and provide appropriate interventions like chest decompression, needle decompression, or bag-valve-mask ventilation. It is important to remember that the airway and breathing are closely linked, and managing one can affect the other. For example, managing an obstructed airway can improve breathing, and providing oxygenation can improve the airway.
What to Look For: Labored breathing, asymmetrical chest movement, signs of chest trauma, or penetrating wounds to the torso.
Indications for Treatment: Tension pneumothorax, open chest wounds, flail chest.
Contraindications: Needle decompression should be avoided in the absence of signs of tension pneumothorax. Be cautious with chest seals on deep, narrow wounds where they may not adhere properly.
Circulation
Circulation: The fourth step is to assess and manage circulation. In a tactical situation, hemorrhage or shock can lead to cardiovascular compromise. It is essential to assess the patient's vital signs and provide appropriate interventions like fluid resuscitation or vasopressors. It is crucial to remember that the interventions chosen should be appropriate for the patient's condition and should not worsen other injuries or conditions.
What to Look For: Weak or absent pulse, cold clammy skin, confusion or unconsciousness, rapid heart rate.
Indications for Treatment: Signs of shock, significant blood loss, low blood pressure.
Contraindications: Fluid resuscitation should be carefully managed in cases of heart failure or pulmonary edema. Vasopressors should be used cautiously, considering the overall fluid status and potential for worsening hemorrhage.
Hypothermia/Head Injury
The final step is to manage hypothermia and head injuries. Hypothermia can occur due to prolonged exposure, while head injuries can occur due to trauma. Both conditions can have significant consequences and should be managed appropriately. Hypothermia can be managed by providing appropriate insulation and warming measures. Head injuries can be managed by assessing for signs of intracranial hemorrhage and providing appropriate interventions like monitoring and transport to a higher level of care.
What to Look For: Shivering, cold skin, confusion, loss of coordination, signs of trauma to the head.
Indications for Treatment: Any patient exposed to cold environments, particularly those with impaired consciousness or severe injuries.
Contraindications: Rapid rewarming can be dangerous in severe hypothermia. Avoid aggressive manipulation of the neck in suspected spinal injuries.
Section 2: The MIST Report
Mechanism of Injury
Understanding the mechanism of injury is crucial for anticipating potential complications. This part will explain how different injury mechanisms, like blasts or falls, can imply varied internal and external traumas. For example, if a team member was injured by an explosion, we would describe the type of explosion and the location of the explosion.
Injuries Sustained
A comprehensive inventory of injuries is vital for guiding immediate treatment and preparing for subsequent medical interventions. For example, if the team member suffered a laceration to the leg and a concussion, we would list both injuries.
Signs and Symptoms
Observing and recording signs and symptoms provide a real-time overview of the patient's condition. For example, if the team member is exhibiting signs of shock or if they are experiencing difficulty breathing, we would list those symptoms.
Treatment Provided
Documenting administered treatments is critical for continuity of care. List all of the treatments that we have provided to the team member. This could include administering first aid, administering medications, or stabilizing the team member for transport to a medical facility.
