WOUND- Seniors' Notes

Most superficial layer of stratified epithelial cells.

Epidermis

The two layers of epidermis

Outer Layer of Dead Keratinized Cells
Inner Cellular Layer Where Melanin and Keratin are Formed

Thickest later of the skin and is made of fibrous elastic tissue

Dermis

The two layers of dermis

Papillary
Reticular

The superficial layer lying deep to the dermis

Papillary

Type of tissue composing the papillary layer

Loose Connective Tissue

Deep layer forming dense connective tissue that constitutes the bulk of the dermis

Reticular

What type of tissue is the subcutaneous tissue composed of?

Adipose tissue

The wound edges of this wound are clean and its bleeding is usually controlled

Intentional Wound

The wound edges of this wound are usually jagged, and bleeding is uncontrolled

Unintentional Wound

This wound is uninfected and does not enter the respiratory, alimentary, genital and urinary tracts.

Clean Wound

This is a surgical wound that enter the respiratory, alimentary, genital and urinary tracts

Clean Contaminated Wound

This wound has minimal infection

Clean wound

This wound has no evidence of infection

Clean Contaminated Wound

An open, fresh, accidental or surgical wound involving a major break in sterile technique

Contaminated Wound

In this wound the tissue becomes inflamed and risk for infection is high

Contaminated Wound

The wound contains dead tissues and evidence of clinical infection such as purulent drainage

Dirty or Infected Wound

Dermis & Epidermis; heals by regeneration

Partial Thickness

What is the direction of healing?

Dermis to Epidermis (Upward)

This wound involves the dermis, epidermis, subcutaneous tissue and possibly the muscle and bone

Full Thickness

This type of wound heals within days to weeks. Wound edges are well-approximated

Acute Wound

The healing time of this wound in delayed while the infection is increased

Chronic Wound

An open wound wherein the wound edges are in close approximation and aligned

Incision

An open wound wherein the tissues are torn and wound edges are often jagged.

Laceration

What is used in laceration?

Blunt instrument and machinery

An open wound due to penetration of the skin and often underlying tissues by a sharp instrument

Puncture

An open wound due to unintentional penetration of the skin and underlying tissues (bullet)

Penetrating

An open wound caused by tearing a structure from a normal anatomic position causing possible damage to blood vessels, nerves, and other structures

Avulsion

Also known as bruise

Contusion

A close wound that results in soft tissue damage and ruptured blood vessels due to a blow from a hard object

Contusion (Bruise)

An open or closed wound caused by secretion and release of toxins by living organisms

Microbial

An open or closed wound due to chemical agents such as acids

Chemical

An open or closed wound due to extremely high or low temperature

Thermal

An open or closed wound due to ultraviolet light or radiation exposure

Irradiation

The 4 phases of wound healing

Inflammatory Phase
Inflammation Phase
Proliferative Phase
Maturation Phase

This phase is initiated immediately after injury

Inflammatory Phase

How many days does the inflammatory phase lasts?

3-6 days

The cessation of bleeding

Hemostasis

This results from vasoconstriction of the larger blood vessels in the affected area, retraction of injured blood vessels and deposition of fibrin and formation of blood clots in the area

Inflammatory Phase

These responses intend to remove any foreign substances and dead and dying tissues

Inflammation Phase

What happens if blood supply to the wound increases during inflammation phase?

Brings oxygen and nutrients needed in the healing process

Thsi phase extends from day 3 or 4 to 21 post injury

Proliferative Phase

This phase begins during day 21 and can extend 1 or 2 years after injury

Maturation Phase

A light and porous and readily molds into the body

Gauze

A type of bandage designed for a specific body part

Binder
