Study Notes
Epistaxis and Risks
- Severe epistaxis poses a risk of vomiting and aspiration, requiring careful monitoring during treatment.
Shock Definitions
- Hypoperfusion is synonymously referred to as shock, indicating a critical condition due to inadequate blood flow.
Blood Clotting and Medications
- Patients on blood thinners experience slower blood clotting, increasing risks during bleeding emergencies.
Pelvic Fracture Management
- In cases of open-book pelvic fractures, applying a compression device around the pelvis is vital due to potential internal bleeding.
Hematemesis
- The medical term for vomited blood is hematemesis, indicating serious underlying conditions.
Challenging Bleeding Control
- External bleeding control is most difficult with a femoral artery laceration, especially when blood pressure is stable.
Hypovolemic Shock
- Hypovolemic shock occurs when the body cannot cope with rapid blood loss, leading to critical impairment of circulation.
Wound Dressing Protocol
- If blood saturates a pressure dressing, additional dressings should be placed over the wound to manage bleeding effectively.
Blood Loss from Fractures
- A fractured femur can lead to the loss of over 1 liter of blood into thigh tissues.
SAMPLE History Importance
- During the SAMPLE history assessment, it is crucial to note if the patient is on blood-thinning medications, as this can impact treatment decisions.
Definition of Perfusion
- Perfusion is defined as the circulation of blood within an organ, crucial for meeting its metabolic needs.
Average Blood Volume
- An adult male weighing 80 kg has an approximate blood volume of 5.60 liters, which is essential for understanding hemorrhage impacts.
Nosebleeds and Head Trauma
- Bleeding from the nose following head trauma signals a possible skull fracture and should not be halted by pressure.
Controlling Bleeding
- For significant wrist lacerations, apply direct pressure to control bleeding, which is the first critical response.
Causes of Nasal and Oral Bleeding
- Possible causes for bleeding from the nose and mouth include skull fractures, high blood pressure, and sinus infections.
Tourniquet Application
- When using a stick and square knot as a tourniquet for severe bleeding, stop twisting the stick once bleeding ceases.
Blood Vessels as Containers
- Blood vessels are considered "containers" in the cardiovascular system, crucial for understanding blood flow management.
Blood Flow Tolerance
- The heart and brain cannot tolerate a lack of blood flow for more than a few minutes due to their high metabolic demands.
Patient Assessment in Transport
- If a patient with abdominal pain becomes diaphoretic and unresponsive, repeat the primary assessment to reassess their condition.
Transport for Abdominal Trauma
- For patients with significant abdominal bruising and rapid pulse from assault injuries, immediate transport is the most appropriate action.
