Environmental/Overdoses/Infectious/Abdominal Flashcards
(32 cards)
Stages of a thermal burns
Emergent, fluid shift phase, hypermetabolic phase, resolution
What is the emergent phase of burns
Release of catecholamines in response to pain. Can be fatal on its own, elderly most at risk
What is the fluid shift phase
Shift of intravascular to extravascular space surrounding the tissue
When does volume loss peak?
At 8 hr but continues for up to 24hr. Hypotension after several hours therefore need to start bolus earlier
What is the hypermetabolic phase
Large increase in body’s demand for nutrients as it begins healing. Increases hr &bp
Equation of death
Age of pt + TBSA burns = 100< = pt death
What is the resolution phase
Formation of scar tissue and return to normal function around area
Electrical Burns
Disturb normal electrical conduction in body, damage to internal organs w no outward appearance
Acids vc Alkali burns
Acids- coagulation necrosis (melt tissue on surface of skin only)
Alkali- no coagulation layer, liquification necrosis
Types of burns
Thermal, electrical, chemical, radiation, inhalation
Rule of nine’s adult vs child
Differences in head and legs. Adult leg = 18, child 13.5. Head adult=9, child 18.
What is a complex burn
Any electrical, chemical, inhalation burn, eye, face, entire hand or foot, circumferential burn, perineum, pts with fxs, elderly, immunosuppressed.
Cyanokit (Hydroxocobalamin)
18> 70mg/kg over 30 mins max 5g
18<= 5g over 15-30min 5g max
Parkland burn formula
4ml x weight (kg) x TBSA = ml infused. Infuse 1/2 amount in first 8 hr, other 1/2 over following 16 hr
What is rhabdomyolysis
Extensive muscle necrosis and release of intracellular muscle components into circulation
Temps for moderate and severe hypothermia
Moderate 32< Severe 32>=
Drowning defenition
Death from submersion w/i 24 hrs of submersion
Near drowning defenition
Death does not occur after submersion or death after 24 hrs of subermsion
Fresh water drowning
Hypotonic water goes through bronchioles into alveoli crossing to vascular space. Fluid in vasc space moves into RBCs and explode. Washes away lung surfactant. Vasodilation due to toxins
Salt Water
Hypertonic- water flows from bloodstream into lungs. Draws fluid into alveoli from vasc space via osmosis. Pulm edema,
Dive emergencies (descent)
Increase intrathoracic pressure (barotrauma) where air is forced from lungs to vasc space. Pulm air embolism, severe pn, bleeding in sinuses/ears/eyes
Dive emergencies of ascent
Nitrogen bubbles form in arterial blood supply and travel to lung. Pulm and cerebral a/e. The “bends” migrate to tissues/joints etc
Cholinergic overdoses
Kills pests/plants, stimulate parasym ns
SLUDGE (Cholinergic)
Salivation, lacrimation, urination, defecation, gastro distress, emesis
