Study Notes
Types of Inflammation
- Inflammation is a natural bodily response to injury or infection.
- Inflammation can be acute or chronic.
- Acute inflammation is a short-term response involving mainly neutrophils as the primary inflammatory cells.
- Chronic inflammation is a long-term response involving mainly lymphocytes as the primary inflammatory cells.
Chronic Inflammation
- It is a delayed response that lasts longer.
- It results in more tissue damage than acute inflammation.
- The body is unable to clear the insult so a granuloma may form as a protective process.
- Granulomas are collections of macrophages that form in response to chronic inflammation.
- Granulomas have their own blood supply allowing them to survive.
Comparison of Acute & Chronic Inflammation
- Acute inflammation is a short-term response, while chronic inflammation lasts longer.
- Neutrophils are the main cells involved in acute inflammation, while lymphocytes are the main cells involved in chronic inflammation.
- Acute inflammation is characterized by redness, heat, swelling, and pain, while chronic inflammation often has less obvious symptoms.
Wound Healing
- Wound healing is a complex process involving different stages and factors.
- There are many causes for wounds, both intentional and unintentional.
- Wounds can be classified into different types based on their characteristics, including open or closed, clean or contaminated.
- Age, gender, nutrition, and systemic diseases can all influence wound healing.
Stages of Wound Healing
- Wound healing can occur by primary, secondary, or tertiary intention.
- Primary intention (first intention) refers to the healing of a clean, closed wound, such as a surgical incision.
- Secondary intention (second intention) refers to the healing of an open wound, such as a deep burn.
- Tertiary intention healing involves intentionally delaying the closure of a wound.
Primary Healing
- Primary intention healing involves three stages: inflammation, proliferation, and maturation.
- The inflammatory stage involves the formation of a blood clot, migration of phagocytes, and fibroblasts.
- The proliferation stage sees epithelial cell proliferation, angiogenesis (formation of new blood vessels), granulation tissue formation, and contraction.
- The maturation stage involves collagen degradation and remodeling, leading to a stronger scar.
Secondary Healing
- The stages of secondary intention healing are similar to those of primary intention, but more intense.
- There is more necrotic tissue present, leading to sloughing.
- Secondary intention healing involves a more abundant blood supply to reduce or prevent infection.
Comparing Primary & Secondary Intention
- Primary intention healing involves the healing of a closed wound, while secondary intention healing involves the healing of an open wound.
- Primary intention healing results in a smaller scar, while secondary intention healing results in a larger scar.
Tertiary Healing
- Tertiary intention healing involves intentional delay of wound closure.
- It is often used for wounds that are contaminated or infected.
- Wound closure is delayed until the infection is controlled.
Factors Affecting Wound Healing
- Wound healing can be affected by both local and systemic factors.
- Local factors include the presence of foreign bodies or infection.
- Systemic factors include age, gender, smoking, nutrition, and diseases.
Complications of Wound Healing
- Complications of wound healing can include hemorrhage, infection, dehiscence (wound opening), fistula (abnormal passage), and keloid scar.
- These complications can be caused by various factors, including inadequate closure, infection, and poor blood supply.
