Asepsis
Absence of pathogenic disease producing microorganisms
Medical Asepsis
Reduce and precent the spread of microorganisms
- Clean technique
Surgical Asepsis
Procedures to eliminate all microorganisms
- Sterile technique
Wound
A disruption of the integrity and function of tissues in the body
Acute Wound
A wound that proceeds through an orderly and timely reparative process that results in sustained restoration of anatomical and functional integrity
Chronic Wound
A wound that fails to proceed through an orderly and timely process to produce anatomical and functional integrity
Abrasion
A superficial wound with little bleeding and is considered a partial-thickness wound
Puncture Wound
Usually a small, circular wound with the edges coming together towards the center
Epidermis
The superficial, thinner layer of skin, composed of keratinized stratified squamous epithelium.
Dermis
A layer of dense irregular connective tissue laying deep in the epidermis.
Pressure Ulcer
A localized injury to the skin and underlying tissue, usually over a bony prominence, as a result of pressure, or in combination with shear and/or friction
Epithelialization
Healing by the growth of epithelium over a denuded surface. The formation of granulation tissue into an open wound allows the re-epithelialization phase to take place, as epithelial cells migrate across the new tissue to form a barrier between the wound and the environment.
General Anesthesia
Loss of all sensation, reflexes, and consciousness
Regional Anesthesia
Loss of sensation to a large area of the body
