AMS trigger Flashcards
If diminished LOC what types of Ddx should we focus on
coma/stupo
for + neuro deficits in AMS what types of ddx should we look for
structural defects of the brain
if altered behavior in a pt who is awake, alert, w/o neuro deficit perform what exam to differentiate between confusion/delerium from a psych disorder
MMS (mini mental status exam?)
If your patient comes in with refractory hypoglycemia and reports they take glipizide for their DM, what would you treat them with
ocreotide
sulfonyureas!! (glipizide, glimepiride, glyubride)
A social hx of chronic alcohol/malnutrition in an AMS patient could suggest what etiology
wernicke’s encephalopathy
what are the 6 DM medications that immediatly warrant admission in pts w hypoglycemia for serial glucose monitoring
- Prandin (repaglinide)
- Starlix (nateglinide).
- glipizide
- glyburide
- glimpiride
- long acting insulin
what are typically the first symptoms to occur in ketoacidosis (be speific )
polydipsia
polyuria
RFs for DKA with initial BG of < 250
- recently recieved insulin
- T1DM young and vomiting
- alcohol abuse/liver failure (impaired gluconeogenesis)
- low caloric intake
- depression
- pregnancy
what are the levels of potassium that determine whether correction of potassium deficits are needed in hypoglycemia
> 5.2 = only need insulin.
3.3-5.2 = 20-30 mEq of K to each LITER of NS + insulin
< 3.3 = only need K
If glucose does not decrease by 10% 1 hour after giving initial insulin bolus/drip what should you do
give .14U/kg bolus then resume normal drip
If youre treating a pt w insulin and their glucose decreases faster than 75md/dL/hr what should you do
decrease insulin drip by half
once a patients glucose reaches 200mg/dL after treatment for DKA, what do you do
- switch IV fluids to D5(1/2) NS
- decrease insulin dose to .02-.05 U/kg/hr
what type of fluid do you give a pt with DKA for fluid rescucitation
- .9% NS 15-20ml/kg/hr for 1 hr
- .45NS TKO
- After initial bolus if Na is normal/elevated switch to 1/2NS
- if Na is low after initial bolus stay on .9%NS
what are the goals for monitoring after management of DKA
- recheck electrolytes, AG, VBG Q2 hrs
- Goal: return all electrolytes to normal ranges and keep K+ between 3.3-5.2 mEq/dL
- Goal: Reduce AG and improve acid-base balance
Indications and criteria for Thrombectomy
Indications:
1. tPA CI
2. tPA ineffective in a pt w NIHSS >/=6
Criteria:
1. Large artery occlusion in anterior circulation (CT/MRA dx)
2. small infarct core w no hemorrhage!
3. 24hrs of symptom onset
4. must be at stroke center w experienced surgeons
