lethal triad =
acidotic + hypothermic + coagulopathic
CT head shows gray-white blurring =
Diffuse axonal injury
How to calculate fluids for a burn patient?
Parchland Formula
4 x kg body weight x % surface area burned = fluids in 24 hr
To calculate % surface area burned = rule of 9s
infection prophylaxis for burn patients?
Topical mupirocin
Topical silver sulfadiazine
How to assess the long term treatment of someone with Afib
Rate control (Beta blocker), Rhythm control, Anticoagulation
Angicoagulation (CHA2DS2-VASc)
If score 0-1 = ASA only
If score 2+ = oral anticoagulation (NOAC, Warfarin with INR 2-3)
What does giving fluids to someone and then them becoming hypertensive, bradycardic and go into respiratory depression indicate?
Cushing’s reflex = indicates elevated ICP
Blunt abdominal trauma leading to a GI perforation most commonly affects what portion of the tract?
Damage to mesenteric blood supply leads most commonly to jejunal ischemia
AFP? beta-hCG?
nonseminomatous germ cell tumor
seminomatous tumor
Nonseminomatous = elevated AFP, elevated beta-hCG
Seminomatous = normal AFP, elevated beta-hCG, increased placental Alk Phos
calf is rapidly worsening, swollen, tense, exquisitely tender, pain worsened by passive extension, distal pulses intact =
compartment syndrome (soft tissue swelling)
DDX
Emergent warfarin reversal
Fresh Frozen Plasma (FFP) - the most rapid method
Vit K - reverses slowly, depends on the synthesis of new vit K dependent clotting factors
Prothrombin Complex Concentrate (PCC) - has prothrombin for rapid reversal + Vit K for long term reversal - used for Intracranial hemorrhage
pathogenesis of vasovgal syncope
increased parasympathetic activity -> bradycardia -> peripheral vasodilation -> decreased CO -> syncope
Differential for Low Ca, High Phos
Low PTH - primary hypoparathyroidism
Low Vit D 2/2 CKD
pathology of hyperventilation as a treatment for increased ICP
Hyperventilation -> decreases PaCO2 -> cerebral vasoconstriction -> decreased cerebral blood flow -> decreased cerebral blood volume -> decreases ICP
What is ICP consist of (3) and what are ways to reduce it
ICP = 3 compartments
Ankle Brachial Index cut off for occlusive PAD
ABI greater than 0.90 is diagnostic for occlusive PAD
Fever, lower abdominal/flank pain, leukocytosis, increased pain when hip is extended, less pain when hip is flexed
Psoas abscess
metaclopramide - pro motility or anti motility?
Promotility - dopamine antagonist
Colonic watershed areas (2)
Premature infants with grunting, flaring, retractions, central cyanosis immediately after birth =
Treatment?
Respiratory Distress Syndrome
Treatment = continuous
Acrocyanosis =
Blue extremities + Pink body
Indomethacin contraindication =
intraventricular hemorrhage
-Indomethacin used to close PDA
To keep PDA open =
Which conditions require an open PDA to survive? (4)
prostaglandin E1
PDA is required in =
Pathogenesis of Fanconi anemia
Chromosomal breaks due to DNA repair problem
Down syndrome + Upper motor neuron symptoms =
atlantoaxial instability
