NURSE-3101 Lecture Notes - Lecture 11: Air Mattress, Safety Pin, Debridement
Document Summary
Bleeding controlled: unexpected trauma (e. g. , accident). Open: skin surface broken, bleeding, tissue trauma. Closed: from blow or trauma such as fall or assault, skin intact but soft tissue damage, internal injury and bleeding. Primary intention: skin edges approximated, risk of infection low, heals quickly. Secondary intention: loss of tissue, open and fills with scar tissue, takes longer to heal. Tertiary intention: left open after potential contamination during surgery, closed later. Bowel surgery where stool has entered the peritoneum. Inflammatory phase: pain, heat, redness, swelling, mildly elevated temperature, elevated wbc count, malaise. Proliferation phase: new tissue built to fill wound space, new tissue called granulation tissue. Maturation: weeks after injury, scar formation. Best wound healing if wound is moist, not wet. Maceration: skin softening/break down from prolonged exposure to moisture. Symptoms 2-7 days: contaminated/traumatic wounds 2-3 days after injury, surgical wound infection 4-5 days post-op. Purulent drainage: increased drainage; pain; redness; swelling; fever; elevated wbc count.
