| A | B |
|---|
| surgical etiology of wounds | incision and excision |
| traumatic etiology of wounds | mechanical, thermal, chemical |
| chronic etiology of wounds | pressure and venous stasis ulcers |
| scar | cicatrix |
| phases of wound healing | inflammatory, fibroplastic, remodeling |
| inflammatory phase | exudate, inflammation, fibrin, dried plasma seal |
| fibroplastic phase | epithelialization, collagen synthesis, contraction |
| remodeling or maturation phase | scar tissue, fibrin reorganization, and decreased vascularity |
| Primary or first intention healing | incised wound, no contamination, drainage, min. scar |
| Second intention | left open, filled with granulation |
| Third intention | delayed closure after debridment |
| types of intentional/surgical wounds | incisions, banding and chemical |
| types of intentional wounds | trauma - must preserve life first |
| clean wound | surgical, aseptic, no inflammation or flora |
| clean contaminated wound | surgical, normal flora or minor break, no infection |
| contaminated wound | fresh trauma or major break, gross flora, or inflammation |
| dirty or infected wound | older trauma, dirty, fecal, organisms, infection, perforation |
| closed wound | injured tissue without broken skin |
| open wound | skin barrier is broken |
| simple wound | skin injury without damaged tissue underneath |
| complicated wound | damaged tissue or penetration |
| factors in wound healing | hemostasis, inflammation, contamination and pt. health |
| patient health factors in healing | Oxygen, age, nutrition, obesity, drugs, immune response |
| Surgical Techniques in healing | asepsis, hemostasis, approximation, tissue handling |
| avulsion | flap of soft tissue |
| adhesions | tissues that stick together |
| amputation | loss of soft tissue and bone |
| contusion | bruise |
| abrasion | scrape |
| pround flesh | overabundant scar formation |
| complications of healing | hematoma, scar, adhesions and disruption |
| hematoma | collection of blood |
| scar | cicatrix |
| Langer's Lines | incision lines that create less scar |
| Keloid | inherited trait with fibrin proliferation |
| keloid treatment | steroid injection, pressure injection |
| adhesions | fibrous band binding 2 surfaces |
| cause of adhesions | inflammation, powder, lint, mechnical injury to serosa |
| wound disruption | separation of wound edges |
| dehisence | part or total separation of wound layers |
| evisceration | opening of wound with organs protruding |
| treatment for evisceration | Moist sterile dressing, NPO, prep for OR |
| Wound infection | organisms in susceptible host, virulence is greater than immune response |
