The Hidden Danger: Recognizing and Responding to Internal Bleeding
While external bleeding is often dramatic and immediately visible, internal bleeding is a far more insidious and equally life-threatening emergency. Hidden from view, it can go unnoticed until severe symptoms appear, making early recognition by a first aider crucial. Internal bleeding occurs when blood escapes from damaged blood vessels or organs inside the body, pooling within body cavities or tissues. If left untreated, it can lead to significant blood loss, shock, organ failure, and death.
At Ready 4 Everything Training and Supplies, we teach the importance of looking beyond the obvious. Recognizing the subtle, yet critical, signs of internal bleeding is a skill that can lead to timely professional medical intervention and save a life.
What is Internal Bleeding?
Unlike a cut on your skin, internal bleeding happens within your body's tissues or organs, or into body cavities like the abdomen, chest, or skull. Because the blood cannot escape, it accumulates internally, putting pressure on organs and potentially leading to severe blood loss and shock.
Common Causes of Internal Bleeding:
Internal bleeding is typically caused by blunt force trauma, where the body is hit or compressed without breaking the skin. Common scenarios include:
Motor Vehicle Collisions: Impact injuries to the chest, abdomen, or head.
Falls from Heights: Leading to impact on internal organs or fractures that cause internal bleeding.
Sports Injuries: High-impact sports or collisions can cause internal trauma.
Assaults: Blows to the torso or head.
Crush Injuries: Where the body is compressed by a heavy object.
Medical Conditions: Certain medical conditions (e.g., ruptured ectopic pregnancy, bleeding ulcers, aneurysms) can also cause internal bleeding without external trauma.
Recognizing the Signs and Symptoms: The "What to Look For"
Since you can't see the bleeding, you must rely on indirect signs. These can be subtle at first and often mimic other conditions, but they tend to worsen as blood loss increases. Look for a combination of these indicators, especially after a mechanism of injury that suggests internal trauma:
Pain and Tenderness:
Severe pain at the injury site or in the general area (e.g., abdominal pain after a blow to the stomach).
Tenderness when the area is touched.
Rigidity or guarding of the affected area (e.g., a hard, distended abdomen).
Swelling and Bruising (Hematoma):
Discoloration (bruising) and swelling may develop over time at the injury site. This indicates blood pooling under the skin.
A large lump or bulge at the injury site.
Signs of Shock: As blood loss increases, the body will begin to show signs of shock (as discussed in Week 4):
Pale, cool, clammy skin.
Rapid, weak pulse.
Rapid, shallow breathing.
Restlessness, anxiety, confusion.
Excessive thirst.
Nausea and vomiting.
Decreased level of consciousness or unresponsiveness.
Blood from Body Openings (May indicate internal bleeding):
Vomiting blood (bright red or "coffee grounds" appearance).
Coughing up blood (bright red or frothy).
Blood in urine (pink, red, or dark brown).
Blood in stool (bright red, dark red, or black and tarry).
Bleeding from the nose, ears, or any other body opening after a head injury.
Changes in Body Shape/Function:
Deformity of an extremity or joint.
Difficulty breathing or chest pain after chest trauma.
Weakness or paralysis in an extremity.
What to Do: Providing Immediate Care for Suspected Internal Bleeding
Your primary goal as a first aider is to recognize the possibility of internal bleeding, prevent shock from worsening, and ensure immediate transport to professional medical care.
Ensure Scene Safety: As always, ensure your safety before approaching.
Call 911 Immediately: This is critical. State clearly that you suspect internal bleeding and describe the mechanism of injury and the signs you observe. Emphasize the urgency.
Maintain ABCs (Airway, Breathing, Circulation):
Ensure the person has an open airway and is breathing. Be prepared to start CPR if they become unresponsive and stop breathing normally.
Monitor for signs of shock.
Position the Person:
Lay the person on their back.
If there are no signs of head, neck, or spinal injury, elevate their legs 12 inches (30 cm) to help improve blood flow to the vital organs (this is for shock management).
If they are unresponsive or vomiting, place them in the recovery position (on their side).
Maintain Body Temperature: Cover the person with a blanket or coat to prevent heat loss, even if the weather is warm. This helps conserve the body's energy.
Do NOT Give Food or Drink: Do not offer anything by mouth, as they may require surgery or other medical procedures.
Reassure the Person: Keep them calm and informed that help is on the way.
Monitor Continuously: Observe their level of consciousness, breathing, pulse, and skin color closely until EMS arrives. Note any changes and report them to paramedics.
Why Early Detection is Life-Saving
The human body can compensate for blood loss for a period, but eventually, its compensatory mechanisms fail, leading to rapid deterioration. The sooner medical professionals are aware of suspected internal bleeding, the sooner they can initiate definitive treatment, which often involves surgery or specialized medical procedures to stop the bleeding source. Your ability to connect the dots and suspect internal bleeding after a significant injury directly impacts the chances of survival and recovery.
