chapter 38 Flashcards
What are the ways that wounds can occur?
trauma
burns
surgery
pressure
Tissue injury without breaking skin
Contusion (bruise)-
Tissue injury that damages a blood vessel, pooling of blood under unbroken skin
Hematoma
Wrenching or twisting of a joint with partial rupture of its ligaments.
Causes swelling
Sprain
type of closed wound
contusion
hematoma
sprain
Surgically made separation of tissue with clean, smooth edges
Incision
Traumatic separation of tissues with irregular, torn edges
Laceration
Traumatic scraping away of surface layers of skin
Abrasion
Wound made by sharp, pointed object through skin or mucous membranes and underlying tissue
Puncture
Variable-size open wound through skin and underlying tissues made by bullet or metal or wood fragment
Penetrating
Tearing away of structure or a part, such as a fingertip, accidentally or surgically
Avulsion
Excavation of skin and/or underlying tissue from injury or necrosis
Ulceration
Death or injury to cells
Necrosis
open wound
Incision
Laceration
Abrasion
Puncture
Penetrating
Avulsion
Ulceration
Necrosis
Superficial
wounds heal more quickly
new skin cells are produced by the epithelial cells that remain in dermal layer of skin
partial thickness wound
dermal layer no longer present
granulation tissue fills in defect
wound heals by contraction
full thickness
internal organ or body cavity tissue opened, usually because of infection or penetrating wound
perforation
tissue significantly disrupted or compressed because of high level of force being applied
crush
the phases of wound healing are
inflammation
proliferation
maturation
is a localized protective response brought on by injury or destruction of tissues
inflammation
Phase begins IMMEDIATELY AFTER INJURY
last approximately 3 or 4 days
inflammation
it includes constriction of blood vessel
platelet aggregation
and formation of fibrin
inflammation
hemostasis occurs in what phase
inflammation
blood clotting or vessel compression and clot formation
hemostasis
