II. Epidemiology

  1. Hemorrhage is the leading cause of Trauma related death (typically within hours of presentation)
    1. Accounts for 40% of all Trauma deaths (esp. multi-system Trauma)
    2. Two thirds of Hemorrhage deaths occur in first 6 hours

III. Pathophysiology

  1. Significant Blood Volume loss causes impaired Oxygen Delivery
  2. With Hypoxemia, cellular metabolism relies on anaerobic glycolysis; Lactic Acid is produced with Metabolic Acidosis
  3. Tissue swelling and cell death result from proinflammatory mediator release, vascular endothelial cell injury
  4. Compensatory endogenous Catecholamines result in Tachycardia, increased Cardiac Output, and Vasoconstriction
  5. Compensation ultimately fails leading to cardiovascular collapse

IV. Precautions

  1. Recognize and definitively manage signs of shock early (see above)
    1. Most cases are Hemorrhagic Shock in the Trauma patient
    2. Paramount to locate and stop the source of bleeding (and replace losses)
  2. Comprehensive examination of the patient may be best evaluation tool in Hemorrhagic Shock
    1. Check distal extremity warmth and pulses
    2. Continue to assess occult bleeding sites (see causes of below)
  3. Hemorrhage Classification is a documentation and coding tool (not a Hemorrhage Management tool)
    1. Degree of Hemorrhage is often difficult to quantify or grade until retrospect
    2. Do not delay definitive management before patient meets a precise classification
  4. Vital Signs are a poor predictor of degree of Hemorrhage
    1. Shock Index (by contrast with Vital Signs) does correlate with degree of Hemorrhage
      1. Mutschler (2013) Crit Care 17(4): R172 [PubMed]
    2. Blood Pressure is unreliable for reassurance in a Trauma patient
      1. Frequently repeat Blood Pressure readings during Resuscitation
      2. Blood Pressure is the last hemodynamic marker to fall
        1. Vasoconstriction and Tachycardia are earlier compensation
      3. Hypotension in Trauma suggests Class III Hemorrhage or worse (>30% blood loss)
      4. Narrowed Pulse Pressure is a better marker in shock (Vasoconstriction increased DBP)
    3. Heart Rate may also be unreliable for reassurance in a Trauma patient
      1. See Delayed Tachycardia
      2. Patient may have lost ability to mount a tachycardic response (e.g. Beta Blocker use)
      3. Athletic fitness
      4. Autonomic Dysfunction may limit compensatory Tachycardia reflex
      5. Abdominal Hemorrhage may cause vagal response (Bezold-Jarisch)

V. Risk Factors: Massive Hemorrhage (requiring Massive Transfusion)

  1. Assessment of Blood Consumption Score (ABC Hemorrhage Score) >2
  2. Positive Focused Assessment Sonography for Trauma (FAST)
  3. Hypotension with Blood Pressure 90 mmHg or less
  4. Tachycardia with Heart Rate 120 bpm or higher
  5. Penetrating Injury
  6. Elevated serum Lactic Acid
  7. Low End-Tidal CO2
    1. End-Tidal CO2 may also be moderately reduced in Hyperventilation
    2. Very low End-Tidal CO2 (<15) suggests poor perfusion
    3. Stone (2017) Injury 48(1): 51-7 [PubMed]

VII. Causes: Hemorrhage Compartments (Mnemonic: "Blood on the floor, and 4 more")

  1. External sites and scalp
  2. Occult Traumatic Hemorrhage sites
    1. Chest
    2. Pelvis
    3. Abdomen (and Retroperitoneum)
    4. Thigh and long bones

IX. Symptoms

  1. Generalized weakness
  2. Syncope
  3. Altered Mental Status or Confusion
  4. Lethargy

X. Exam

  1. See Shock
  2. See Trauma Evaluation
  3. Complete Trauma Evaluation
    1. Sources of bleeding (chest, Abdomen, Pelvis, retroperineum, long bones)
    2. Completely expose the patient (Mnemonic: Armpits, Back and Breasts, Butt cheeks and Sac)
    3. Evaluate for Scalp Lacerations, Epistaxis (including posterior bleeding)
    4. Evaluate for flank Ecchymosis, Scrotal Swelling, pulsatile abdominal mass, unstable Pelvis
  4. Reassess frequently
    1. Young healthy patients may with little warning, precipitously decompensate into cardiovascular collapse
  5. Tachycardia
    1. See Heart Rate for normal ranges for age
    2. Early warning sign of shock in most cases
    3. Cold and tachycardic is shock until proven otherwise
    4. However Heart Rate can be misleadingly normal in cases of Delayed Tachycardia (see above)
  6. Urine Output
    1. Normal Urine Output is >0.5 ml/kg/h in adults (>1 ml/kg/h in children, >2 ml/kg/h in infants)
  7. Arterial Injury Findings
    1. Hard Signs
      1. Pulsatile Bleeding
      2. Absent distal pulses
      3. Expanding hematoma
      4. Arterial Bruit
      5. Arterial thrill
    2. Soft Signs
      1. Initial pulsatile bleeding at prehospital evaluation
        1. Resolution of pulsatile bleeding does not exclude arterial bleeding
        2. Arterial spasm after injury may obscure hard arterial injury findings
      2. Non-expanding hematoma
      3. Neurologic deficits
      4. Close proximity of wound to major vessels

XI. Labs

  1. See Shock
  2. Complete Blood Count with Platelet Count
    1. First Hemoglobin is unreliable within first 8 hours of Hemorrhage (provides baseline for trending)
  3. Venous Blood Gas
    1. Degree of Metabolic Acidosis may help grade shock severity
  4. Coagulation Pathway Labs (INR, aPTT)
  5. Type and Crossmatch for Blood
  6. Ionized Calcium
    1. Hypocalcemia may decrease hemodynamics and increase Coagulopathy
  7. Pregnancy Test (urine HCG or serum HCG)
  8. Other tests
    1. Thromboelastography (TEG/ROTEM)
      1. Measures viscoelastic blood properties which may help guide transfusions

XII. Diagnostics

XIII. Imaging

  1. Focused Assessment with Sonography for Trauma (eFAST)
    1. Free fluid within Abdomen or Pelvis
    2. Pericardial Effusion or Cardiac Tamponade
    3. Hemothorax
    4. Pneumothorax
  2. Rapid Ultrasound in Shock (RUSH Exam, "Pump, Tank and Pipes")
    1. Pump Evaluation (Cardiac Systolic Function)
    2. Tank Evaluation (Vascular volume status)
      1. See Inferior Vena Cava Ultrasound for Volume Status
    3. Pipes Evaluation (Large vessel integrity)
      1. See Abdominal Aorta Ultrasound
  3. Chest XRay (portable)
    1. Hemopneumothorax
  4. Pelvis XRay (portable)
    1. Pelvic Fracture
  5. Femur or Hip XRay (or other Long Bone XRay)
    1. Obtain as indicated
  6. CT Chest AbdomenPelvis with IV contrast (if stable enough)
    1. Consider with CT Angiography for vascular injury
    2. May identify bleeding source and targets for surgical or endovascular management
  7. CT Spine
    1. Consider if Neurogenic Shock suspected
  8. CT Angiography
    1. Consider in suspected extremity arterial injury

XIV. Differential Diagnosis

  1. Cardiogenic Shock
    1. Tension Pneumothorax
    2. Cardiac Tamponade
  2. Neurogenic Shock secondary to spinal cord injury
    1. Neurogenic Shock does not occur in isolated intracranial injury
  3. Other non-Traumatic shock
    1. See Shock for Undifferentiated Shock approach
    2. Hypovolemic Shock (e.g. Dehydration)
    3. Septic Shock

XV. Evaluation

  1. Hemorrhage Classification (Class I-IV) is unreliable
    1. See Hemorrhage Classification
  2. Shock Index
    1. Shock Index = (Heart Rate) / (Systolic Blood Pressure)
    2. Shock Index >0.9 predicts need for increased transfusion requirements and early mortality risk
  3. Assessment of Blood Consumption Score (ABC Hemorrhage Score)
    1. Four point score (Penetrating Trauma, SBP<90 mmHg, Heart Rate>120, positive FAST Exam)
    2. ABC Hemorrhage Score 3 or 4 predicts Massive Transfusion Protocol
  4. Trauma Associated Severe Hemorrhage (TASH)
    1. Based on SBP, pulse, gender, Hemoglobin, FAST Exam, Base Excess and pelvic/Femur Fracture
    2. Yucel (2006) J Trauma 60(6):1228-36 +PMID:16766965 [PubMed]
  5. McLaughlin Score
    1. Based on pulse >105 bpm, sbP <110 mmHg, pH<7.25, Hematocrit <32%

XVI. Management: Hemorrhage Control

  1. Emergent Trauma surgery Consultation
    1. Poor response to Fluid Replacement or blood replacement indicates surgical management (or via angiography)
  2. Stop external bleeding immediately
    1. Apply direct manual pressure to external bleeding sites
    2. Pressure dressing may replace manual pressure if it adequately controls bleeding
      1. Israeli Bandage is elastic wrap with gauze impregnated with clotting agent
      2. Sanitary napkins or pads may also be used with overlying direct pressure at wound site
      3. Maintain direct pressure over bandage as needed to control bleeding
    3. Rapidly bleeding sites (e.g. Scalp Wounds) may be temporized with staples or Suture
    4. Consider occult Hemorrhage sources (see above)
    5. Bleeding refractory to manual pressure
      1. Notify Trauma surgery of emergent surgical intervention for rapid, uncontrolled bleeding
      2. Tourniquet (Pneumatic Tourniquet or Windlass Tourniquet)
        1. Indicated for rapid extremity bleeding not controlled with direct manual pressure
        2. Temporizing only until surgical intervention within 1-2 hours
        3. Permanent ischemic injury occurs if Tourniquet left in place >4-5 hours
        4. Ineffective in junctional sites (e.g. axilla, groin, adductor canal)
        5. Obviously unusable at neck and trunk
      3. Topical Hemostatic Agent (Chitosan Dressing, Zeolite Mineral Dressing, Kaolin Mineral Dressing)
        1. Indicated for rapid bleeding in sites where Tourniquets cannot be used (see above)
        2. Not widely available outside of military and large Trauma Centers as of 2013
        3. Risk of wound contamination with hemostatic agent
      4. Foley Catheter
        1. Inserted into a bleeding wound site
        2. Balloon inflated with Normal Saline
        3. May be effective at bleeding sites where Tourniquets may not be used
          1. Consider at junctional sites (e.g. groin, neck)
      5. XStat (RevMedX, limited efficacy and safety data)
        1. FDA approved for gun shot wounds in 2014
        2. Syringe filled with small, compressed cellulose sponges
        3. Syringe applicator inserted at exsanguinating gun shot wound
  3. Non-compressible Massive Hemorrhage
    1. Emergency Thoracotomy (in Cardiac Arrest)
      1. Massive chest Hemorrhage with CPR <15 min in Penetrating Trauma, CPR <10 min in blunt Trauma
    2. Resuscitative Endovascular Balloon Occlusion of the Aorta or REBOA (Peri-Arrest with systolic Blood Pressure <70 mmHg)
      1. Massive intraabdominal or pelvic Hemorrhage
    3. Pelvic Binder
      1. Unstable Pelvic Fracture with separation (e.g. open book or vertical sheer Pelvic Fracture)
      2. Apply binder empirically pre-imaging if Pelvic Fracture suspected in the Peri-Arrest, Hemorrhagic Shock patient
  4. Additional stabilization measures while temporizing until definitive surgical management
    1. Tranexamic Acid (Cyklokapron)
      1. Blocks plasmin formation (preventing Fibrinolysis)
      2. TXA 1 g IV load over 10 minutes, then 1 g IV over 8 hours
      3. May be indicated in first 1-3 hours following onset of Hemorrhage
        1. Consider when other measures fail and surgical intervention delayed
        2. Small mortality benefit in these cases
        3. Roberts (2011) Lancet 377(9771):1096-101 [PubMed]
    2. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA)
      1. Percutaneous balloon delivered via groin catheter and inflated in aorta above level of Hemorrhage
      2. Indicated in severe bleeding Pelvic Fractures who have not had Cardiac Arrest
        1. Used as an immediate temporizing measures, pending emergent definitive surgical management

XVII. Management: Volume Replacement

  1. Two large bore IVs (14 or 16 gauge if able, otherwise 18 gauge)
    1. Shorter tubing and larger bore provides faster IV rate
    2. Intraosseous Access if peripheral IV not immediately attainable
    3. Obtain Central Venous Line as available
      1. Large catheter introducer (8F or 9F) is preferred over multilumen
  2. Intravenous Fluids and Packed Red Blood Cells
    1. See Fluid Resucitation in Trauma
    2. Judicious use of crystalloid in Class II Hemorrhage or higher
      1. React to early signs and symptoms of acute blood loss with Hemorrhage control and blood replacement
      2. ATLS and textbooks still describe the use of NS or LR for 1-2 Liter bolus
      3. However, new practices suggest limiting crystalloid in favor of Blood Products (permissive Hypotension)
        1. Goal systolic Blood Pressure 80-100 mmHg
        2. IV fluids may artificially increase local pressure at non-compressible clot sites causing rebleeding
        3. IV fluids may dilute Coagulation Factors and Platelets
        4. Bickwell (1994) N Engl J Med 331(17): 1105-9 +PMID:7935634 [PubMed]
      4. Restrictive Resuscitation (permissive Hypotension) contraindications
        1. Prolonged transport time
        2. Transfer to Trauma Center
        3. Traumatic Brain Injury
        4. Hypotension, negative FAST Exam and normal Hemoglobin
      5. References
        1. Spanger and Inaba in Herbert (2015) EM:RAP 15(3):6-8
    3. Hemorrhage should be replaced with Blood Products
      1. Indications
        1. Mean arterial pressure 65 (or systolic Blood Pressure 70-90 mmHg)
          1. May need to target higher MAP (e.g. 80 mmHg) in Head Injury
        2. Poor response to IV fluids
          1. Persistent Tachycardia, Hypotension or Tachypnea
          2. Urine Output <50 ml/hour (<1ml/kg/hour)
      2. Start with 2-4 units (prepare at least 4 units pRBC for more severe Hemorrhage)
        1. Type specific blood can be ready within 30-40 minutes
        2. In the crashing patient give unmatched type-specific blood, Low titer O or O negative blood
          1. Men may be given O+ Blood
          2. Give RhoGAM prior to discharge if found to be Rh Negative (prevents future reactions)
      3. Massive Hemorrhage with administration of more than 4 units requires matching Blood Products
      4. Consider Autotransfusion (e.g. Hemovac or Cell Saver)
        1. Indicated for massive bleeding if blood can be drained and not contaminated)
      5. Use blood warmer when available
        1. Prevents Hypothermia with transfusion

XVIII. Management: Traumatic Coagulopathy Correction

  1. Mechanism
    1. Acute Traumatic Coagulopathy is a major cause of Hemorrhage related deaths
    2. Hemostasis requires Platelet adherence to damaged vessel endothelium, then stabilized clot with Fibrin
    3. Traumatic Coagulopathy results from multiple factors
      1. Tissue injury, inflammation and hypoperfusion (shock) are key initial factors in Coagulopathy
      2. Progressive shock and hemodilution with Intravenous Fluid worsens Coagulopathy
      3. Hypothermia (<34 C) and acidosis also worsen Coagulopathy
  2. Coagulopathy correction for Massive Blood Transfusion (>10 pRBC units within 24 hours)
    1. See Massive Blood Transfusion for protocol
    2. Massive Blood Transfusion is typically accompanied by Platelet and Plasma Transfusion
    3. Replace 1 unit of plasma for every 1-2 units of Packed Red Blood Cells
    4. Replace 1 unit of apheresis Platelets (6 pack equivalent) for every 8 units of Packed Red Blood Cells
    5. Consider Fibrinogen replacement to 1.5 to 2.0 g/L
    6. Prothrombin Complex Concentrate (PCC) 1-2 doses
      1. Do not use beyond 6-7 hours from bleeding onset (due to increased clotting risk)
    7. Holcomb (2012) Arch Surg 15:1-10 [PubMed]
  3. Monitoring of Traumatic Coagulopathy
    1. Viscoelastic hemostatic assays (e.g. TEG) have largely replaced INR and PTT for monitoring
    2. See Thromboelastography (TEG)
  4. Coagulopathy correction for underlying disorder or medication
    1. Reverse Anticoagulants
      1. See Emergent Reversal of Anticoagulation
      2. Platelet Transfusion for antiplatelet agents (e.g. Aspirin, Clopidogrel)
      3. Protamine for Heparin
      4. Vitamin K, FFP and PCC4 for Warfarin
    2. Specific management for Congenital Blood Coagulation Disorders
      1. Von Willebrand Disease
      2. Hemophilia A
      3. Hemophilia B (Factor IX Deficiency)
    3. Specific management for Acquired Blood Coagulation Disorders
      1. Cirrhosis
        1. Consider Vitamin K supplementation
        2. Decreased Anticoagulant and coagulant factors
          1. Therefore, not typically coagulopathic despite abnormal PT/INR and PTT
      2. Disseminated Intravascular Coagulation (DIC)
        1. Platelet Transfusion to Platelet Count >50,000/mm3
        2. FFP transfusion until PTT and PT/INR are each <1.5x normal
        3. Do not administer Tranexamic Acid (or other antifibrinolytic)
      3. Thrombotic ThrombocytopeniaPurpura
        1. Plasmaphoresis
      4. Drug induced Thrombocytopenia
        1. Withdraw offending medication
      5. End-stage renal disease
        1. Results in Anemia and Thrombocytopenia
        2. Hemodialysis
        3. Erythropoietin
        4. Cryoprecipitate
        5. Conjugated Estrogen
        6. Desmopressin
        7. Tranexamic Acid

XIX. Management: Other measures and disposition

  1. Immediately stabilize and transfer to Trauma Center or to proper hospital service (e.g. Trauma service)
    1. Limit unnecessary studies that delay transfer
    2. Goal for disposition and transfer is 20 minutes
    3. Involve surgical consultants, intervention radiologists early
  2. Monitoring
    1. Vital Signs (Heart Rate, Blood Pressure, Pulse Pressure)
    2. Mental status
    3. Urine Output via urine catheter (unless suspected Urethral Trauma)
    4. Lactic Acid and Base Excess
  3. General measures
    1. ABC Management
    2. Prevent Hypothermia
    3. Continue to limit further bleeding
    4. Pelvic Binder (or bound bedsheet) for suspected unstable Pelvic Fracture
    5. Pregnant patients in left lateral decubitus position (see Trauma in Pregnancy)
    6. Replace Blood Products and prevent Coagulopathy (see above)
    7. Reverse hypoperfusion
    8. Continually reevaluate for concurrent injuries (e.g. Tension Pneumothorax, Cardiac Tamponade)

XX. Management: Damage Control Surgery Protocol

  1. Stage 0: Ground Zero (pre-hospital and emergency department)
    1. Rapid transfer to Trauma Center and operating room
    2. Stopping Hemorrhage is the primary priority
    3. Prevent Hypothermia
    4. Venous Blood Gas
  2. Stage 1: Initial Operation to control life threatening injuries and bleeding
    1. Control Hemorrhage
    2. Control contamination

    5. Prevent Hypothermia
  3. Stage 2: ICU Resuscitation
    1. Resuscitation and monitor perfusion
    2. Correct acidosis and Coagulopathy
    3. Rewarm the patient
    4. Optimize oxygenation and ventilation
    5. Measure intraabdominal pressure

Definition (MEDLINEPLUS)

Bleeding is the loss of blood. It can happen inside or outside the body. Bleeding can be a reaction to a cut or other wound. It can also result from an injury to internal organs.

There are many situations in which you might bleed. A bruise is bleeding under the skin. Some strokes are caused by bleeding in the brain. Other bleeding, such as gastrointestinal bleeding, coughing up blood, or vaginal bleeding, can be a symptom of a disease.

Normally, when you bleed, your blood forms clots to stop the bleeding. Severe bleeding may require first aid or a trip to the emergency room. If you have a bleeding disorder, your blood does not form clots normally.

Definition (NCI_NCI-GLOSS) In medicine, loss of blood from damaged blood vessels. A hemorrhage may be internal or external, and usually involves a lot of bleeding in a short time.
Definition (NCI) The flow of blood from a ruptured blood vessel.
Definition (MSH) Bleeding or escape of blood from a vessel.
Definition (CSP) escape of blood from the vessels; bleeding.
