examples of absorbable suture
catgut
polyglycolic (dexon)

poligleacaprone (monocryl)
suture removal times for body parts
Face and neck: 3 to 5 days
Scalp and body: 5 to 7
Extremities: 7 to 12 days
What are the areas of the body or situations that require special attention and or hospitalization?
- Partial thickness greater than 20% body
- Burns of face, hands, feet, genitalia, major joints.
- 3rd degree burns
- Electrical burns
- Chemical burns
- Inhalation injury
Clinical features that are suspicious for child abuse?
- delay seeking medical advise
- burn in shape of object
- sharp demarcated boarder, bilateral
- cigarette burns
Ratings of hypothermia, 3 levels?
Core body temp below?
Mild: 32-35 Celsius 35 = 95 F
Moderate: 28-31.9 C
Severe: <28
Dysbarism?
Decompression sickness, arterial gas embolism, barotrauma
Decompression sickness
Path
Sx
Tx
Nitrogen bubbles in tissues during ascent
Type 1: Deep aching pain in large joints (bends).
Type 2: Cardiorespiratory
Type 3: arterial gas embolism: air in the interstitial space or pulmonary veins
Tx: 100% O2, Iv fluids, possibly hyperbaric chamber.
Acute mountain sickness
Sx:
Tx:
Sx: HA with GI disturbance, dizziness, fatigue or sleep disturbance
Tx: Decent is definitive treatment
- Rest, supplemental O2, NSAIDs, antiemetic
- Dexamethasone for moderate or severe cases only
High altitude pulmonary edema
Sx:
Tx:
Rapid ascent above 8000ft.
Most lethal of all altitude sickness
Sx: dry cough, decrease exercise perf,
- late: dyspnea at rest, productive cough, pink frothy sputum
- later: AMS, coma
Tx: O2 and decent best treatment, Nifedipine
Burn assessments regarding surface area?
Rule of nines: Each area represents 9%
- head, anterior chest, anterior abdomen, each arm, anterior each leg, posterior each leg.
Can use palmar method: size of patients palm represents 1% of their body surface area.
Define first degree burns
Pres
w/u
tx:
Superficial, epidermis
Presentation: erythema only, no blistering
w/u: consider cause of burn
Tx: irrigate w/ NS, non-adherent dressing, topical abx, elevate, NSAIDs, OP follow up
- No systemic abx unless signs of infection then keflex
Define 2nd - 4th degree burns
Pres
w/u
tx:
2nd: Partial thickness, epidermis and dermis = erythema plus blisters
3rd: Full thickness, subQ = pink, white or brown, skin appears smooth and leathery, painless
4th: Burns to muscle and bone = eschar, “deep burn necrosis”
W/u: survey for immediate life threats
- Calculate TBSA
- ABG, carboxy-hgb, CBC, electro, ect.
- CXR
Tx: ABCs!, IV fluids, wounds etc.
Burn severity scale
Mild: < 10% body, <5% child or elderly
Moderate: 10-20%, 1/2 for kids, elders
Major: >20% partial thickness burns or 3rd degree or specific types or locations of burns
Complications from burns?
Fluid, electrolyte, protein loss…
Infection
Airway compromise
Circumferential burns: compartment syndrome
