radial art line
42
which is higher rad art line or NIBP cuff during hypoTN?

common metabolic derrangement after brain death
Diabetes Insipidus!
45
MCC of preop anemia
iron def anemia
46
SAH and recent surgical femur fracture now gets PE, what to do next?
Catheter directed therapy -> direct clot removal or dissolution
47
pt having cataracts surgery, has a hx of controlled HTN and hypothyroidism, preop testing?
none indicated
48
risk of hyperthermic intraperitoneal chemotherapy w/ cisplatin
-given in dextrose solution -> hyperglycemia -hypoNa can occur -must cool pt, see inc HR, CO, O2 consumption, dec SVR (pressure compresses IVC)
49
how does neonate switch from fetal to neonatal circulation?
dec in PVR -inc LA pressure closes PFO
50
what anesthetic drugs dec immune response
opioids
51
Goals for spinal drains
-MAP 80-100 -CSF pressure 8-12 -draining less than 15-25 cc/hr
52
What drug abuse will screw w/ your teeth?
Methamphetamines
53
perk of robotic surgery over laparoscopic
more degrees of freedom w/ manipulation of surgical instruments
54
Airway pressure release ventilation
