does age increase risk of stroke for non neuro cases
yes, 62 or older
do heart problems increase risk of stroke for non neuro cases
yes, MI within 6 months
do kidney problems increase risk of stroke for non neuro cases
yes, hx of ckd or dialysis imply pt w vascular dz
do pt with pulm problems increase risk of stroke for non neuro cases
yes, copd and smoking increases risk
does obesity increase risk of stroke for non neuro cases
actually no, bmi higher decreases risk of stroke
who has a higher risk of stroke for non neuro cases. akd vs dialysis pt
acute kidney disease pt
what metabolic disease predisoe pt to periop stroke
htn
in pt with sub arach hemorrhage…what 3 things predict m&M
degree of bleed, action to correct bleed, presence of vasospasm
what is the greatest predictor of vasospasm in sub arch hemorrhage
the degree of bleeding
what is pseudotumor cerebri
it is increased ICP secondary to decreased resorption of csf
what anesthestic technique is contraindicated in pseudotumor cerebri
non
can spinals be done in psuedotumor cerebri
actually it is one of the treatments
who is at increased risk for recall under general anesthesia
patients with long history of substance abuse, alcohol use, chronic opiod/ benzo use,
why dose substance abuse have increased of recall
their cyp450 are increased and thus metabolism of anesthetic agents
what kind of surgeries predispose pt to recall
pt who cannot tolerate low bp or high anesthetics…like cardiac or c-section
how does neuromusclar blocking drugs increase rate of recall
bc monitoring movement under ga can help us indicate low anesthesia…paralysis prevents this assessment
what is core temperature
brain temperature
does measureing bladder temperature over or underestimate core temp
it underestimates core…core could actually be colder than what bladder temp shows
where can u measure core temp
distal esoph, pa cath, tympanic, nasopharynx
what does general anesthesia do to the threshold of thermoregulation
it decreases the threshold
does “decreasing” threshold for thermoregulation make sense?
yes it does…decreasing threshold means that the temperature at which shivering and other mechs for temp maintanence is dropped to a lower temp…thus you wont shiver until you are reallllly cold
by how much does GA decrease the threshold for thermogenesis
2-3 degrees celcius
is agitation post op considered post op delerium
yes…it is a hyperactive variant
