  1. Bleeding: Chapter 22 page 650

  2. The Significance of Bleeding • When patient have serious external blood loss it is often difficult to determine the amount of blood that is present because it may be absorbed into the surface the patient is on or clothing. • It may also be diluted when mixed with other liquid

  3. Blood Volume • The body will not tolerate more than 20% blood volume loss • Blood volume: 70mL per 1kg of body weight • Adult= about 6L • 1 year old infant= about 800mL

  4. Hypovolemic shock • Hypovolemic shock- a condition in which low blood volume results in inadequate perfusion • Be aware for the following conditions: • Significant MOI • Poor General Appearance • Assessment reveals signs and symptoms of shock: • Pale • Clammy/diaphoretic • Increased pulse • Decreased BP • You note significant blood loss • Blood loss is rapid • You cannot control bleeding • *all bleeding should be treated as soon as the airway is managed and the patient is breathing

  5. Characteristics of Bleeding • Arterial- Blood is bright red and spurts. • Venous- Blood is dark red and does not spurt. • Capillary- Blood oozes out and is controlled easily

  6. Coagulation • Bleeding normally stops within 10 minutes due to coagulation-the process in which a clot forms to close a hole in a blood vessel • Some medications interfere with clotting • Some injuries will be unable to clot • Patients with hemophilia lack clotting factors

  7. Emergency Medical Care • Follow BSI precautions • Ensure patient has an open airway and adequate breathing • Provide oxygen if necessary • There are several methods to control bleeding • Direct pressure and elevation • Pressure bandage • Pressure points • Splints • Air splints • Pneumatic anti-shock garment • Tourniquet

  8. Direct Pressure and Elevation: • Direct pressure is the most common and effective way to control bleeding • Apply pressure with gloved finger or hand • Elevating a bleeding extremity often stops venous bleeding • Use both direct pressure and elevation whenever possible • Apply a pressure dressing

  9. Pressure Points • If bleeding continues, apply pressure on pressure point. • Pressure points are located where a blood vessel lies near a bone • Be familiar with the location of pressure points

  10. Splints • Splints can help control bleeding associated with a fracture • Air splints can be used to control bleeding of soft-tissue injuries

  11. Pneumatic Antishock Garment (PASG) • Stabilizes fractures of the pelvis and proximal femurs • Controls significant internal bleeding • Controls massive soft-tissue bleeding of the lower extremities (Refer to local protocol) • Contraindications include: • Pregnancy • Pulmonary edema • Acute heart failure • Penetrating chest injuries • Groin injuries • Major head injuries • Less than 30 minute transport time

  12. Tourniquet • Only to be used as a last resort for uncontrolled bleeding • Application: • Fold a triangular bandage into 4˝ cravat • Wrap the bandage • Use a stick as a handle to twist and secure the stick • Write “TK” and time. Place on patient • Precautions: • Place as close to injury as possible, but not over joint • Never use narrow material • Use wide padding under the tourniquet • Never cover a tourniquet with a bandage • Do not loosen the tourniquet once applied

  13. Bleeding from the Nose, Ears, and Mouth • Causes include: • Skull fractures • Facial injuries • Sinusitis • High blood pressure • Coagulation disorders • Digital trauma

  14. Controlling a Nose Bleed • Epistaxis- Nose Bleed • Follow BSI precautions • Help the patient sit and lean forward • Apply direct pressure by pinching the patient’s nostrils • Or place a piece of gauze bandage under the patient’s upper lip and gum • Apply ice over the nose • Provide transport

  15. Bleeding from skull fractures • Do not attempt to stop the blood flow • Loosely cover bleeding site with sterile gauze • If cerebrospinal fluid is present, a target (or halo) sign will be apparent

  16. Internal Bleeding • NOTE: Internal bleeding may not be readily apparent. • Assess patient’s: • Mechanism of injury • Nature of illness

  17. Signs and Symptoms • Ecchymosis: Bruising • Hematoma: Bleeding beneath the skin • Hematemesis: Blood in vomit • Melena: Black, tarry stool • Hemoptysis: Coughing up blood • Pain, tenderness, bruising, guarding, or swelling • Broken ribs, bruises over the lower chest, or rigid, distended abdome

  18. Hypoperfusion • Signs and Symptoms: • Change in mental status • Tachycardia • Weakness • Thirst • Nausea or vomiting • Cold, moist skin • Shallow, rapid breathing • Dull eyes • Dilated pupils • Weak, rapid pulse • Decreased blood pressure • Altered level of consciousness

  19. Treatment of Hypoperfusion • Follow BSI precautions • Maintain airway and administer oxygen • Control external bleeding and care for any internal bleeding • Monitor and record vital signs • Elevate legs and keep patient warm • Transport immediately
