Study Notes
Shock Management and Hemorrhage Control
- In cases of severe injury, it's crucial to follow appropriate standard precautions before providing care.
- For patients with a large laceration, direct pressure to the wound is vital after ensuring safety.
- The ability of the cardiovascular system to compensate for blood loss is closely related to the rate of bleeding.
Patient Profiles and Assessment
- A 70-year-old man with a history of COPD and high blood pressure presents with a severe nosebleed, most likely caused by his hypertension.
- Signs of intra-abdominal bleeding often include pain and distention rather than hypotension or bruising.
Blood Volume and Shock Indicators
- An infant can show shock symptoms after losing as little as 100 mL of blood from a total blood volume of 800 mL.
- Dizziness upon standing is an early indicator of internal bleeding in non-trauma patients.
Clotting and Hemostasis
- Blood stasis and vessel wall changes can significantly affect the blood's ability to clot.
- Applying a topical hemostatic agent with direct pressure is one effective method for controlling severe bleeding, such as from a femoral artery injury.
Understanding Blood Vessels
- Arterioles are smaller vessels that carry blood away from the heart, connecting arteries to capillaries.
- Systemic veins are responsible for returning deoxygenated blood back to the heart, completing the circulatory cycle.
Gastrointestinal Bleeding Indicators
- Hematemesis, or vomiting blood, strongly suggests the presence of gastrointestinal bleeding.
External Bleeding Management
- Most external bleeding can typically be controlled by applying local direct pressure rather than other methods like elevation or gauze packing.
