Types of Bleeding and Assessment
Understanding the type of bleeding is crucial for effective treatment.
- Arterial Bleeding: Bright red blood spurting in pulses. This is the most dangerous type due to the high pressure and rapid blood loss. This requires immediate and aggressive intervention.
- Venous Bleeding: Dark red blood flowing steadily. While less immediately life-threatening than arterial, it can still lead to significant blood loss.
- Capillary Bleeding: Oozing blood, often minor and easily controlled. This is typically associated with superficial wounds, such as abrasions and small cuts.
Assessment Steps:
- Scene Safety: Ensure the area is safe for you and the patient (e.g., traffic, environmental hazards).
- Patient Response: Assess the patient's level of consciousness (AVPU: Alert, Verbal, Pain, Unresponsive).
- Bleeding Source: Identify the source of bleeding and the type of bleeding.
- Severity: Assess the amount of blood loss (e.g., blood soaked clothing, pooling blood).
Bleeding Control Techniques
The following techniques are implemented in a step-wise manner.
- Direct Pressure: The primary method for controlling bleeding. Apply firm, direct pressure to the wound using a clean cloth or dressing. Maintain pressure until bleeding stops. If the first dressing soaks through, do NOT remove it; apply another dressing on top and continue pressure.
- Elevation: Elevate the injured limb above the heart, if possible, to reduce blood flow to the area.
- Wound Packing: If direct pressure and elevation are insufficient, and the wound is deep or in an area difficult to apply pressure (e.g., junctional areas like the armpit or groin), pack the wound tightly with hemostatic gauze or clean gauze, and apply direct pressure.
- Tourniquet: A last resort when other methods fail or if the bleeding is life-threatening (e.g., severe arterial bleeding from a limb) and direct pressure is ineffective. Apply the tourniquet 2-3 inches above the wound (proximal), avoiding a joint. Tighten the tourniquet until the bleeding stops. Note the time of application and ensure it remains visible (e.g., write the time on the tourniquet). Do not loosen a tourniquet once applied, unless directed by medical personnel.
Hemostatic Agents (if available):
- These agents (e.g., gauze impregnated with clotting factors) can enhance blood clotting and can be used in conjunction with wound packing. Follow manufacturer's instructions.
Wound Care: Cleaning, Dressing, and Bandaging
Proper wound care helps prevent infection and promotes healing.
- Cleaning: Gently clean the wound with mild soap and water or sterile saline. Avoid harsh chemicals or scrubbing. Remove any visible debris.
- Dressing: Apply a sterile dressing appropriate for the wound type (e.g., gauze pads, adhesive bandages). Choose a dressing that covers the entire wound and provides adequate padding. Consider the type of wound: abrasions need an absorbent dressing; deep wounds may need packing.
- Bandaging: Secure the dressing with tape or a bandage. Ensure the bandage is snug but not too tight to impede circulation. Check for signs of impaired circulation (e.g., numbness, tingling, coolness, or cyanosis) and adjust the bandage if needed. Note that in some instances, such as a major laceration, the wound may be better off with direct pressure to control bleeding without dressing it. The dressing can be applied after bleeding is controlled by direct pressure.
Types of Bandages:
* Adhesive Bandages: Ideal for minor cuts and scrapes.
* Gauze and Tape: Versatile and used for various wound types.
* Roller Bandages: Used to secure dressings and provide support.
* Triangular Bandages: Can be used as slings or to secure dressings in areas difficult to bandage.

Key Takeaways
🎯 Core Concepts
The Hemostatic Cascade and its Implications
Beyond simply stopping blood flow, understanding the body's natural clotting process (the hemostatic cascade) provides a deeper understanding of why certain techniques work. This includes appreciating the roles of platelets, clotting factors, and the fibrin network. It also highlights factors that can impair clotting, such as anticoagulant medications or underlying medical conditions.
Why it matters: Knowing the underlying physiology allows for more informed decision-making in emergency situations, helping you predict potential complications and tailor your interventions effectively. For example, understanding that patients on blood thinners may bleed more profusely changes your approach to bleeding control.
Prioritization and Assessment in a Bleeding Emergency
Beyond specific techniques, the ability to rapidly assess the severity of bleeding, identify associated injuries, and prioritize interventions is crucial. This involves considering the mechanism of injury, the patient's level of consciousness, and signs of shock. This goes beyond just treating the wound; it's about evaluating the whole patient.
Why it matters: Efficient prioritization ensures you allocate resources effectively and provide the most critical care first, ultimately impacting patient outcomes. This is a critical skill in any emergency setting.
💡 Practical Insights
Tourniquet Application: Beyond the Basics
Application: Document the time of tourniquet application meticulously. Ensure the tourniquet is placed correctly (2-3 inches above the wound, avoiding a joint). After application, treat the limb with extreme care – the limb is at risk of further damage and should be handled with care. Consider the potential for compartment syndrome and the need for rapid medical transport.
Avoid: Incorrect placement (directly over a joint or too distal), failing to document the time of application, and failing to monitor the patient for signs of complications like shock or neurovascular compromise.
Effective Communication and Scene Management
Application: Clearly and concisely communicate the situation to EMS personnel. Provide an accurate account of what happened, the interventions you've performed, and the patient's current condition. Ensure the scene is safe for both you and the patient (e.g., controlling traffic, removing hazards).
Avoid: Providing incomplete or inaccurate information to EMS, failing to maintain scene safety, and getting overwhelmed by the situation.
