Second intention healing involves:
-primary wound
-wound granulation
-delayed suturing
-minimal scar formation - wound granulation
- The healing stage of first intention healing occurs from the:
- fifth to fourteenth day
-
Which of the following occurences would NOT decrease the healing capabilities of a patient?
a. deficiency in vitamin K
b. radiation therapy
c. early ambulation
d. use of steroids - c early ambulation
- The rupture of a wound with spilling of contents is known as:
- evisceration
-
All of the following are part of the inflammation process EXCEPT:
a. heat
b. pain
c. edema
d. vasoconstriction - d. vasoconstriction
- The healing process in which a wound is purposely left open and allowed to heal from the bottom up is called:
- secondary intention
- The substance that weakly holds wound edges together during the first five days of first intention healing is:
- fibroblasts
- Abnormal attachement of two surfaces or structures that are normally separate.
- adhesion
- A scar.
- cicatrix
- A fibrous protein substance that gives the wound its strength.
- collagen
- Presence of pathogenic microorganisms on or in an animate or in an inanimate vector.
- contamination
- Process of removing dead skin, debris, or foreign bodies from a wound.
- debridement
- Separation of partial or total layers of the surgical wound. 5-10th day Post OP.
- dehiscence
- Extrusion of internal organs (viscera) through a gaping hole.
- evisceration
- Protein, clotting factor.
- fibrinogen
- Long, connective tissue cells.
- fibroblasts
- Tract between two epithelium lined surfaces that is open at both ends.
- fistula
- Healing from bottom up.
- granulation
- A localized accumulation of blood in the tissue.
- hematoma
- Heavy bleeding, usually arising from an artery hemostasis.
- hemorrhage
- Result of wound dehiscence and occurs in lower abdominal incisions.
- herniation
- Invasion of healthy tissue by pathogenic microorganisms.
- infection
- The localized protective reaction of tissue to injury or disease.
- inflammation
- Hypertrophic formation of connective tissue that is often removed surgically--- raised, thickened skin.
- keloid
- Tissue is held together by fibrin and serum time period 3-5 days.
- lag phase
- Skin is intact but underneath was damaged.
- closed wound
- Skin is destroyed.
- open wound
- Skin is destroyed but no loss of tissue or presence of foreign body.
- simple wound
- Approximation-- expected to heal by primary intention.
- clean wound
- Separation of the wound edges that are not correctly approximated.
- dead space
- Death of tissue because nutrients have not reached the wound area.
- gangrene
-
True or False?
Dressings are applied after drapes are removed. -
False-
Dressings are applied before drapes are removed. - A method of applying pressure and stabilizing tissue when it is impossible to dress an area, such as face, neck, or nose.
- stent dressing
- A single-layered or multilayered dressing is applied dry over a clean incision from which no or slight drainage is expected.
- dry sterile dressing (DSD)
- Bulky dressings are added to the intermediate layer of a three-layer dressing after many extensive surgical procedures, especially in plastic surgery and surgical procedures on the knee or breast.
- pressure dressing
- Dressing materials are soaked in sterile normal saline solution or other medicated solution and applied wet. This method provides mechanical debridement and is less painful for the patient.
- wet to dry dressing
- Separation of wound edges.
- wound disruption
