2- look at it with endoscope. if its stopped bellying do a beta blocker then band 1-2 weeks later. continued bleeding- balloon tamponade and increased risk of necrosis. Early rebleeding- repeat endoscopy therapy and need a TIPS or shunt surgery if there is recurrent hemorrhage
178
sclerotherapy
using sodium morrhuate
179
vasopressin what is the risk for varices
risk of MI
180
portocaval shunt
TIPS need to do early- increased risk of encephalopathy because liver is not clearing as much hammonia
181
what is the pathophysiology of cirrhotic liver
scar tissue impedes blood flow into the portal vein, increased pressure in the portal system gets shunted to the splenic vein, and short gastric, esophageal plexus, also in the umbilical vein, inferior rectal and retroperitoneal
182
what is the pathophys of enecphalopatyh
gut bacteria normall detoxifid in the liver, check this by measuring arterial ammonia
183
Childs Criteria
predicts the operative mortality- no ascetis, bill <2, no encephalopathy, alb>3.5 good nutrition, measure with transferring na pre albumin, and operative mortality is the same as if not cirrhotic.
mil ascites- bili 2-3, alb 3-3.5- nitrition no encephalotpy- additional mortality of 155 of the operation
ascite- alb<3, and encephalopathy- morality is 40% plus the risk of the operation. TIPS is places between hepatic vein and branch of portal vein to kill time before transplant
184
Most common reason for transplant
Heptatitis C or B in world, alcohol, and quickly is becoming NASH
185
red whale sign
the impending vatical hemorrhage
186
what are the indications to shunt
stopped drinking, not class C, determine if blood in portal vein goes to or from the liver (retropedal is bd because increased encephalopathy, want heptofugal flow)
187
how do you test for the flow of the liver
colo dopler of portal vein or measure portal pressure by hepatic vein wedge pressure, if <24 do NOT shunt because poor portal flow
188
shunt choices
portocaval- highest risk of encephalopathy. Splenorecnal shnt of Warren does not help portal pressure but lowers encephalopathy because it diverts the spleen flow

321
3-7 days out from the burns what do you do
debris the deep wounds of the palms, soles, genitals, and face
322

not on the night of the burn because need to resusitate the fluids first, let edema resolve around POD3 before applying skin grafts, but usually over 1 week out from the injury
323
30 yo F with TAH with changes in metal status- what is the change in mental status assumed to be first
due to hypoxia until proven otherwise
324
30 yo F with TAH with changes in metal status- A
intubate using size 8- the tip should be 2cm above the carina the tube should be in a round 22 cm
325
30 yo F with TAH with changes in metal status- B
volume controled ventilation- continuous mandartoy vent- c
326

set rate and TV and patient is ignored
327
assist control
set rate with a demand set tidal volume- patient has effort will take in whole tidal volume
328
synchronized intermittent mandartory vent
reate and tidal volume set with demand- they get their normal volume and will not get a forced breath in the same cycle
329
CPAP
demadn rte and TV but the patient must initiate the breaths
330
RR on vent
10-14 breaths. low PCO2 suggests RR should be decreased high CO2 increase the RR
331
what is normal vent TV
6 cc/kg lean body mass
332
choosing FiO2
choose the lowest FiO2 to hit 92% sat-
333
what should you do to the FiO2 for COPD or chronic hypoxemia
use low concentration of O2 because that will correct low PaO2 because they are chronic retainers O2 is their only drive to breath. Too high and get toxicity
334
Peep
at the trend of the res cycle, the glottis covers the cords AND its against the closed glottis. Upside expected to improve lung mechanics and gas exchange as it recruits alveolar units, decrease in atelectasis, improve oxygenation without increase in Fi)2. Increased iCP, and increased onemothroaz and decreased venous return
335
what are the best initial vent settings
IMV, TV of 10-15cc kg, rate is 10 and FitO2 is 100% then wean down. Peep 5 cm. It takes aday to get oxygen toxic, but if notice they have a history of COPD then turn it down
336
who gets the vent
PaO2<60, Pco2>60 unless COPD, loss of protective reflex, RR>33-35, clinical judgement
337

what would a duplex be for in 30 yo F with TAH with changes in metal status
to check for DVT
346
30 yo F with TAH with changes in metal status- management
check ABG again after 20 minutes- medication need heparin to prevent further clotting. follow the PT which you want 1.5-2 time the normal with an INR off 2-3. Consider thrombolytics if the patient is unstable but cannot if there has been surgery in the past two week. Consider transfer to coumadin or the following 306 months
347
30 yo F with TAH with changes in metal status- management if allergic to coumadin
put a filter in the Ivc just below the renal arteris
348
30 yo F with TAH with changes in metal status- if there is no filter available
use miles clips on the IVC below which let some blood through but need to check to make sure there is an intact azygous system

alpha blocker such as clonidine preop
have a nitrodrip ready for HTN crisis
```
366
65 yo with a carotid bruit on the right what operation
carotid endarterectomy
367
what is the pathophysiology HTN with carotid stenosis operation
carotid body is clamped off therefore it thinks you are in hypotension and there is no blood getting there so arenas get signal to increase catecholamines and increase the BP, and you need to turn off the carotid body by injecting ti would lidocaine to inhibit the action potential of the nerves and the carotid body stops communicating
368
65 yo with a carotid bruit on the right patient wakes up and cannot move the left side of the body- what next
need to duplex the carotid artery and then ope nan explore to find the intimal flap and scrape off the intima at the intimate medical junction

418
how to differentiate between Conns and RAS
give captopril and then measure the renin and aldosterone. if low renin and high aldo then its Conn. If the renin and aldosterone are both low then its RAS
419
labs for COnns
CMP, and high aldo level, normal to decreased renin
420
further testing for COnns
iodocholesterol scan, selective venous sampling of an adrenal in to see if one makes more than the other. if R=L then its hyperplasia not cancer or adenoma.
421
