A tourniquet is a medical device used to control severe bleeding by temporarily restricting blood flow to a specific area of the body. It is an essential tool in emergency situations where immediate intervention is required to prevent life-threatening blood loss. In this blog post, we will explore the purpose and application of tourniquets, emphasizing their importance in emergency medical care. MyCPR NOW offers valuable resources and training programs to equip individuals with the knowledge and skills needed to respond effectively in situations that require tourniquet application.
Understanding the Purpose of Tourniquets to Restrict Blood Flow
Tourniquets are specifically designed to control severe bleeding in situations where direct pressure, wound dressings, or other methods of bleeding control are insufficient. They restrict blood supply to the injured limb to prevent life-threatening blood loss. Their primary purpose is to temporarily occlude blood flow to a limb or a specific area of the body, allowing medical professionals to provide proper care and prevent excessive blood loss. Tourniquets are most commonly used in situations such as severe traumatic injuries, accidents, and combat scenarios.
When to Use a Tourniquet
-
Severe Limb Injuries: When there is severe bleeding from a limb that cannot be controlled by direct pressure alone.
- Tourniquets are used to stop life-threatening bleeding when direct pressure is insufficient.
- Multiple Casualties: In mass casualty situations where prioritizing bleeding control quickly is crucial.
- Remote or Austere Environments: Situations where immediate medical help is not readily available, and controlling bleeding is vital until help arrives.
- Traumatic Amputations: When a limb has been partially or completely severed, a tourniquet can control bleeding until advanced medical care is available. It is important to apply pressure to control bleeding until advanced medical care is available.
Key Benefits of Tourniquet Application
1. Rapid Bleeding Control- Effectiveness: Tourniquets are highly effective in rapidly controlling severe bleeding by occluding blood flow to the affected area, preventing further blood loss. They can also be used to control bleeding in the upper extremity, with proper application techniques.
- Stabilization: This intervention helps stabilize the patient’s condition, buying valuable time for advanced medical care to be administered.
- Speed: Tourniquets can be applied quickly, making them ideal for emergency situations where every second counts.
- Survival: The prompt and proper application of a tourniquet can significantly improve survival rates in cases of life-threatening bleeding.
- Resuscitation: By stopping the bleeding quickly, tourniquets enhance the chances of successful resuscitation and increase the patient's overall survival.
- Statistical Evidence: Studies have shown that the use of tourniquets in combat and civilian settings has saved countless lives by preventing exsanguination (severe loss of blood).
- Minimizing Blood Loss: When applied correctly, tourniquets minimize blood loss and reduce the risk of irreversible tissue damage.
- Limb-Saving: This preservation of limb function is particularly important in scenarios where limb-threatening injuries occur, as it allows for more effective treatment and potential limb-saving interventions.
- Compartment Syndrome Prevention: Proper use of a tourniquet can help prevent compartment syndrome, a condition that occurs when there is increased pressure within a muscle compartment.
- Protection for Rescuers: Tourniquets provide a safe and efficient means of bleeding control, reducing the risk of blood exposure to healthcare providers and rescuers.
- Focus on Critical Care: By minimizing the time spent on direct wound management, tourniquets enable responders to focus on other critical aspects of care.
- Ease of Use: Modern tourniquets are designed to be user-friendly, allowing both trained professionals and laypersons to apply them effectively.
Appropriate Tourniquet Application
1. Identify Life-Threatening Bleeding- Assessment: Quickly assess the patient's condition and identify life-threatening bleeding that cannot be controlled by direct pressure or other first-aid measures.
- Indicators: Look for signs of arterial bleeding, such as bright red spurting blood or the presence of a pulsatile flow. Large volume and rapid blood loss are key indicators that a tourniquet may be necessary.
- Choosing the Right Tourniquet: Select a commercially available tourniquet that has been specifically designed for medical use. Examples include the Combat Application Tourniquet (CAT), the SOF Tactical Tourniquet (SOFTT), and the Emergency & Military Tourniquet (EMT).
- Preparation: Ensure the tourniquet is in good working condition, and familiarize yourself with its instructions for proper application. MyCPR NOW provides resources that offer detailed guidance on selecting and preparing tourniquets.
- Training: Regularly train with the tourniquet to ensure proficiency in its use during an actual emergency.
- Placement: Place the tourniquet directly on the affected limb, 2-3 inches above the bleeding site but below a joint if possible. If the exact bleeding site is not identifiable, place the tourniquet high and tight on the limb. For a bleeding arm, ensure the tourniquet is positioned properly to control the bleeding effectively.
- Positioning and Tightening: Follow the manufacturer’s instructions for proper positioning and tightening. Apply the tourniquet tightly enough to restrict blood flow effectively but avoid over-tightening to prevent unnecessary discomfort or damage.
- Visual Checks: Ensure that the tourniquet is not applied over a joint, bulky clothing, or equipment that could interfere with its effectiveness.
- Activation: Activate the tourniquet according to its specific mechanism, whether it involves twisting, pulling, or securing a clasp.
- Securing: Once activated, secure the tourniquet in place to prevent loosening or accidental release. Use the provided locking mechanism to ensure it stays in place.
- Secondary Check: Confirm the tourniquet's effectiveness by checking that the bleeding has stopped or significantly slowed. If the bleeding continues, a second tourniquet may be necessary.
- Reassessment: Regularly reassess the patient's condition, including their vital signs and the presence of distal pulses (pulses beyond the tourniquet site).
- Complications: Continuously monitor the tourniquet site for any signs of complications, such as excessive pain, numbness, or discoloration beyond the tourniquet. Reassure the patient and provide updates on the situation.
- Documentation: Record the time of tourniquet application on the patient or a visible tag, as this information is critical for medical personnel when the patient receives advanced care.
