Skin and Wound
| What are some complications of wounds? | hemorrahage, infection, dehiscence, evisceration, and fistulas |
| what is the second most common HAI (nosocomial) | wound infection |
| Asepsis is | absence of pathogenic microorganisms |
| Medical asepsis uses a | clean technique hands above elbows when scrubbing for 5 min rinse fingertips to elbows |
| Surgical asepsis uses a | sterile technique touch only sterile to sterile catheters, iv insertion etc |
| Primary intention | wound that is closed, like a surgical incision skin edges are approximated or closed low risk for infection minimal scar formation |
| Secondary intention | wound edges not approximated loss of tissue in wound burn, pressure ulcer, severe laceration longer to heal wound left open till it becomes filled by scar tissue |
| What is a clean wound | surgical incision no inflammation no break in sterile technique |
| what is a contaminated wound | operative wound contaminated incision encountering acute non purulent inflammation |
| What is the order of wound healing | hemostasis inflammatory proliferation remodeling/maturation |
| what stage of wound healing is where the injured blood vessels constrict, platlets gather to stop bleeding | 1st stage, hemostasis |
| In what stage does the clots form the fibrin matrix that later provide the framework for celulllar repair | hemostasis |
| what stage of wound healing is when localize redness, edema warmth and trobning occur | 2nd stage, inflammation |
| what stage of wound healing is where vasodilation of surrounding capillaries and migration/movement of serum and wbcs into the damaged tissues | 2nd, inflammation |
| What does the neutrophils do in the | ingest bacteria and small debris |
| what do the monocytes do in the inflammatory stage | transform into macrophages clean wound release growth factors that contracts fibroblasts |
| What do fibroblasts do | cells that synthesize collagen |
| Appearance of new blood vessels as construction progresses occurs in what stage of the healing process | Proliferative stage |
| Epithelialization occurs in what stage of wound healing process | Proliferative stage |
| What stage of healing of wound does collagen mix with granulation tissue to form a matrix | Proliferative stage |
| Maturation or? | remodeling |
| During the remodeling or maturation stage what undergoes reorganization | collagen continues to reorganize and gain strength |
| What are impairments of healing | age, anemia, hypoproteinemia, and zinc deficiency |
