Study Notes

Dehydration

Clinical Manifestations: Lethargic/unconscious, weak/absent radial pulse, sunken eyes, slow skin pinch return (>2 seconds), drinks poorly
Severe Dehydration Treatment:
- Treat shock (if present), administer oral rehydration solution (ORS) while with IV access
- Insert peripheral IV line using large IV catheter (g24)
- Administer Lactated Ringer's and monitor infusion rate, watch for peri-orbital edema (sign of overhydration)
- Observe child within 2 hours, continue ORS if able to drink
- Monitor ongoing losses closely, reassess degree of dehydration and continue IV rehydration if needed, switch to ORS if IV is no longer required
Some Dehydration Treatment:
- Administer ORS for 4 hours, especially for every loose stool or vomiting
- Encourage additional age-appropriate fluid intake, including breastfeeding
- Monitor ongoing losses closely, assess clinical condition and degree of dehydration at regular intervals

Urinary Tract Infection (UTI)

Etiology:
- Cystitis (infection of urethra and bladder)
- Pyelonephritis (infection of ureters up to the kidneys)
- Anatomical abnormality of the urinary tract
- Vesicoureteral reflux (VUR)
- Poor toilet and hygiene habits
- Use of bubble baths or irritating soaps
- Family history of UTIs
- Infrequent urination
- Incomplete emptying of the bladder
- Constipation
- Catheterization
- Previous UTIs
- Children who receive antibiotics
- Tight clothing or diapers
- Sexual intercourse
- Altered urine and bladder chemistry

Burns

Etiology:
- Acids (pH less than 7)
- Bases/alkali compounds (pH greater than 7)
- Friction (contact with flames or hot objects)
- Radiation (overexposure to the sun or ionizing radiation)
Pathophysiology:
- Burns disrupt the skin's barrier, increasing risk of infection
- Three skin layers: epidermis (regenerates), dermis (contains nerves, blood vessels, etc.), hypodermis (temperature regulation)
- Temperatures greater than 44°C (111°F) damage proteins and cells
- Disrupted skin function: sensation loss, water loss, temperature control
- Cell membrane disruption causes fluid and electrolyte imbalance
- Large burns (over 30% body surface area) cause significant inflammatory response, fluid leakage, and blood volume loss
- Hypermetabolic state, increased cardiac output, metabolism, heart rate, and impaired immune function
Types of Burns:
- Superficial (First-degree): Mildest form, inflammation of superficial skin, redness, pain, minor swelling, dry skin without blisters, healing in 3-6 days
- Partial-thickness (Second-degree): Involves deeper skin layers, blisters, severe pain, redness, wet-looking appearance, healing in 3 weeks or more
- Full-thickness (Third-degree): Destroys all skin layers, charred or white appearance, little to no pain (nerve endings destroyed), may require skin grafts, healing can take months
Assessment of Burn Severity:
- Rule of Nines: Body is divided into areas representing 9% (or multiples of 9%) of total surface area
- Lund and Browder Chart: Takes into account different body proportions in adults and children
Therapeutic Management:
- Remove from burning area, prioritize rescuer safety
- Remove clothing from burned area immediately
- Do not break blisters
- Clean wound with lukewarm water
- Early cooling (within 30 minutes) with cool water (10–25 °C) or cold compress for 3-5 minutes
- Elevate burned area
- Remove jewelry and clothing around the burn
- Apply topical antibiotic ointment (Bacitracin, Neosporin, Silvadene)
- Manage first-degree burns without dressings
- Call for emergency medical care for second and third-degree burns
Flame Burn Management:
- Extinguish flames by rolling on the ground
- Stop, Drop, and Roll: Stop what you're doing, drop to the ground, and roll to smother the flames
