Study Notes

Minor and Severe Hemorrhage

Minor hemorrhage is typically venous and stops spontaneously unless influenced by bleeding disorders or anticoagulant medications.
Severe hemorrhage is a primary cause of shock, and internal hemorrhage can occur without visible external bleeding.
Internal spaces that can hold significant blood include the retroperitoneum, pelvis, chest, and thighs.

Control of External Hemorrhage

Direct, firm pressure should be applied using a pressure dressing to control external bleeding.
Pressure can be applied on the involved artery at a point proximal to the wound to effectively control hemorrhage.
Elevating the injured limb is advisable, along with immobilizing the affected extremity.
A tourniquet should be used if the bleeding cannot be controlled; it must be placed just above the wound.
Tagging the patient with a “T” on the forehead is crucial, indicating tourniquet location and application time.

Internal Bleeding

Signs and symptoms of internal bleeding include tachycardia, low blood pressure, increased thirst, apprehension, cool and moist skin, and delayed capillary refill.
Management of internal bleeding often requires blood transfusion, preparation for possible surgery, and obtaining arterial blood gas (ABG) samples for evaluation.
Monitoring and placing the patient in a supine position is essential for assessing condition.

Types of Shock

Shock is characterized by inadequate blood flow to tissues and body cells.
Types of shock include:
- Anaphylactic shock: due to severe allergic reactions.
- Cardiogenic shock: due to heart muscle impairment or failure.
- Distributive shock: results from displacement of intravascular volume.
- Hypovolemic shock: caused by decreased intravascular volume from fluid loss.
- Neurogenic shock: loss of sympathetic tone causing relative hypovolemia.
- Septic shock: due to widespread infection or sepsis.

Stages of Shock

Stage 1: Compensatory
- Blood pressure remains normal with compensatory mechanisms.
- Vasoconstriction, increased heart rate, and contractility help maintain cardiac output.
- Blood is shunted from non-essential organs to vital organs, leading to cool, pale skin, hypoactive bowel sounds, and decreased urine output.
Stage 2: Progressive
- Compensatory mechanisms fail; mean arterial pressure (MAP) drops below normal.
- Patients become hypotensive (BP <90 mm Hg) and show signs of altered mental status.
Stage 3: Irreversible
- There is no effective response to treatment; organ damage occurs.
- Blood pressure remains low despite interventions, and renal/liver dysfunction develops.
- Conditions such as acute metabolic acidosis and lactic acidosis worsen due to anaerobic metabolism.
- The cardiovascular system is unable to maintain adequate MAP for tissue perfusion.

Comparison of Stages of Shock

Finding
- BP: Normal in compensatory, hypotensive in progressive, erratic in irreversible.
- Respiratory Rate (RR): Elevated (>20 in compensatory) to requiring mechanical ventilation in irreversible.
- Skin: Varies from cold and clammy to mottled with petechiae and jaundice.
- Urine Output: Decreased across all stages, with significant concern in later stages.
