pearls Flashcards
osteomyelitis needs a minimum of how long of abx
6 weeks
afib causes
volume overload hypoxia HTn sepsis hyperthyroidism
IVC filters only good for how long
1st 6 months
bacteria common in CAP (typicals vs atypicals)
typicals: #1 strep pneumo, hemophilus influenza, moraxella
atypicals: chlamydia, legionella, mycoplasma
treat CAP empirically
quinolone
azithro + ceftriaxone
quinolones- which ones good for lung and which is good for treating kidneys
lung: levi, mox
kidney: levi, cipro
AKI criteria
increase in Cr>0.3 mg/dL within 48 hours
increase in Cr>1.5x baseline within 7 days
urine vol<0.5 mL/kg/hr for 6 hrs
differences in enoxparin vs heparin in DVT ppx inpatient
equally as effective
enox: q24 hr, cant have AKI
heparin: q12, can have AKI
indications for emergent dialysis
A-acidemia (lactic acidosis)
E-electrolytes (hyperkalemia, hypercalcemia)
I-intoxicant (ethylene glycol, methanol, tylenol)
O-overload (pulm edema, cant use lasix)
U- uremia (BUN rate of rise increases)
which types of fluid to use for volume repletion (losing intravascular volume)
NS
Lactated ringers
side effect of normal saline
hyperchloremic metabolic acidosis
theoretical risks of using normal saline in hemorrhagic or septic shock
hemorrhagic shock: acidosis–>platelets cant bind in acidic env–> hemorrhage worsens
sepsis–> lactic acidosis - NS worsens acidemia
contraindicatio to lactated ringers
ESRD
fluids for maintenence IVF
0.45 NS +/- D5
O,25 NS +/- D5
when do you use maintenance fluids
cant intake oral fluids, NPO for >1 day
maintain daily volume
