Tissue Trauma Flashcards
(40 cards)
Cryosurgery- what is normal for the wound?
What is not normal?
Normal: looks like a burn, with swelling, blistering and tenderness
Infection: Oozing and pain
What is Pityriasis rosea?
rash that usually begins as a large circular or oval spot on chest, abdomen or back.
Called a “herald patch”, this spot can be up to 4 inches across.
The herald patch is typically followed by smaller spots that sweep out from the middle of your body in a shape that resembles drooping pine-tree branches.
Burns over ______% is considered critical and possibly deadly.

What are 3 zones of every burn injury?
Zone of coagulation (inner)
Zone of stasis (middle)
Zone of hyperemia (outer)
How is lead poisoning treated?
Chelation
3 methods of healing wounds
First intention healing: surgical incision, no granulation, minimal scar.
Second intention healing: “healing by granulation”. Involves tissue loss.
Third intention: delayed healing- my need to stay open for drainage. Deep wounds.
Dehiscence
Disruption of wound healing
What is a Curling’s ulcer
acute gastric erosion to the duodenum, which is part of the small intestine. Result of large amounts of stress: severe burns or injuries sustained in a car accident.
Complication from severe burns when reduced plasma volume leads to ischemia and cell necrosis (sloughing) of the gastric mucosa.
Clinical signs of renal hemorrhage
Palpable flank mass with ecchymosis and tenderness.
Hiatal hernia is caused by
weak diaphragm allows stomach to slide into esophagus
and caused by increased intra-abdominal pressure
Obesity
(NOT intrathoracic pressure and Not esophagus weakness)
Symptoms of hiatal hernia
Esophageal reflux
Heartburn
Chest pain
Abdominal pain
Pain with appendicitis
Moderate to severe
Begins in epigastrium or periumbilical then shift to rlq and becomes steady.
Lying flat or sitting helps. Knees drawn toward chest helps.
Gastric resection
Bowel sounds may not be heard for 72 hours post op.
Monitor for hemorrhage: bright red blood from NG tube, tachycardia, hypotension.
What lab is helpful in diagnosing pancreatitis
Amylase
What happens to blood sugar with pancreatitis
Elevates due to reduced insulin production
Melena
Dark tarry stool
Post liver biopsy position
Lie on right side to splint and slow bleeding
3 types of integumentary glands and functions
*Eccrine glands - secrete sweat through pores found in the palms of hands, soles of feet, and forehead
- Sebaceous glands - secrete oily sebum and are found on the chest, back, scalp, face, and forehead
- Apocrine glands - secrete sweat via canals along hair follicles in the underarms, pubic area, anus, and nipple are
Stages of pressure ulcers
- Stage 1: may be painful, no breaks or tears. reddened and does not blanch.
- stage 2: open skin.tender and painful. The sore expands into deeper layers of the skin. It can look like a scrape (abrasion), blister, or a shallow crater in the skin. Sometimes a blister filled with clear fluid.
- stage 3: tissue beneath the skin, forming a small crater. Fat may show in the sore, but not muscle, tendon, or bone. May have tunneling.
- stage 4: very deep, reaching into muscle and bone and causing extensive damage. Damage to deeper tissues, tendons, and joints may occur. Possible eschar, slough, tunneling.
In stages 3 and 4 there may be little or no pain due to significant tissue damage. Serious complications, such as infection of the bone (osteomyelitis) or blood (sepsis), can occur if pressure injuries progress.
Sometimes a pressure injury does not fit into one of these stages- called unstagable.
Stages of burns
- First-degree (superficial) burns: affect only the outer layer of skin, the epidermis. The burn site is red, painful, dry, no blisters. Mild sunburn is an example. Long-term tissue damage is rare and often consists of an increase or decrease in the skin color.
- Second-degree (partial thickness) burns. involve epidermis and dermis. Looks red, blistered, and may be swollen and painful.
- Third-degree (full thickness) burns. destroy the epidermis and dermis. They may go into the innermost layer of skin, the subcutaneous tissue. The burn site may look white or blackened and charred.
Fourth-degree burns. go through both layers of the skin and underlying tissue as well as deeper tissue, possibly involving muscle and bone. There is no feeling in the area since the nerve endings are destroyed.
What does potassium do with burns?
What do fluids do with burns?
Potassium leaks from cells into plasma, causing hyperkalemia.
During first 49 hours after burn, capillary permeability increases allowing fluids to shift from plasma to interstitial spaces.
Which body system is most affected by plumbism?
Lead poisoning
CNS: interferes with neurotransmitter function and can lead to encephalopathy, deceased intellectual function and behavior problems.
