Inflammation, Macrophages, PRICE, Edema Management, and Rehab Concepts

Flashcards covering key concepts from the transcript: macrophage origin and roles, PRICE components, edema management (elevation, compression, ice, heat, and exercise), guarding, and protective devices.

Where do macrophages originate before becoming macrophages, and how long does the conversion take?

They originate as monocytes, and they convert to macrophages over about 24 hours.

What are the two key roles of macrophages in the inflammatory process mentioned in the notes?

Cleanup of debris and chemotaxis signals to recruit more inflammatory cells.

What does PRICE stand for in acute injury management?

Protection, Rest, Ice, Compression, Elevation.

Why can inflammation be excessive in joints like the ankle and knee according to the notes?

Because these joints have large joint capsules, leading to more swelling and potential edema.

What is muscle guarding, and why does it occur?

Protective muscle contraction to guard the injured area.

Name examples of devices used to protect or immobilize an injured area.

Sling, cast, boot, or other supportive devices.

What is the effect of elevation on edema according to the notes?

Elevation helps decrease edema by promoting venous return.

What is the effect of compression on edema according to the notes?

Compression decreases edema.

What is the effect of ice on edema according to the notes?

Ice prevents edema (does not decrease it) and also reduces pain by slowing nerve conduction.

When is ice recommended to be used after treatment?

After treatment to prevent increased inflammation and manage acute injuries.

When might ice be used at initial presentation or during an acute incident in the clinic?

If the patient has too much inflammation or pain that would hinder treatment; ice can reduce inflammation and pain.

What is the effect of heat on tissue viscosity and range of motion?

Heat decreases tissue viscosity, making tissues more extensible and improving range of motion, and aids nutrient delivery.

When is heat typically used in rehab after the early inflammation phase?

After the acute phase, around six weeks, to improve flexibility and tissue nutrition.

What is the role of exercise (muscle pumping) in edema management?

Muscle pumping from exercise helps to decrease edema by promoting venous return.
