Study Notes
Blood Loss and Shock
- A fractured femur can result in the loss of approximately 1 L of blood into the thigh’s soft tissues.
- An infant with a total blood volume of 800 mL can show signs of shock after losing just 100 mL of blood.
- Hypoperfusion refers to inadequate blood circulation, synonymous with shock.
Assessment and Intervention
- For a patient shot in the abdomen, while controlling external bleeding, assist with ventilations if the patient shows shallow breathing and is semiconscious.
- In cases of severe abdominal pain during transport, repeat the primary assessment if the patient becomes diaphoretic and stops conversing.
- Early indications of intra-abdominal bleeding include pain and distention.
Specific Injuries
- Bleeding from the nose post-head trauma suggests a skull fracture and should not be stopped.
- Injury to the spleen is suspected if a patient presents with left upper quadrant pain and shoulder referred pain after blunt abdominal trauma.
- Gastrointestinal bleeding is suspected if a patient exhibits hematemesis (vomiting blood).
Clotting and Coagulation
- Blood stasis, vessel wall changes, and certain medications impair the blood’s ability to clot effectively.
- Applying direct pressure with a sterile dressing is the first step to control bleeding, covering the entire wound with the dressing.
Bleeding Control Techniques
- If direct pressure does not stop severe bleeding from an extremity, apply a tourniquet proximal to the injury.
- External bleeding from a femoral artery laceration is especially difficult to manage, with a blood pressure of 140/90 mm Hg complicating control.
Hypovolemic Shock
- Hypovolemic shock occurs when the body cannot compensate for rapid blood loss, particularly significant when more than 10% of total blood volume is lost.
- Indications of hypoperfusion and shock include low blood pressure and signs of tissue inadequacy such as cyanosis and hypoxemia.
