Chronic active Hep B, high infectivity
Scleral icterus is seen when the TB is ___
> 2.5 to 3 mg/dL

[Type of hepatorenal syndrome]
AKI in less than 2 week with oliguria. More serious
Type 1
[Type of hepatorenal syndrome]
Renal impairment less severe, ascites refractory to diuretics
Type 2
___ syndrome seen i cirrhotic patients mainly due to nitric oxide in the splanchnic circulation causing peripheral vascular resistance
Hepatorenal syndrome
dyspnea in the upright position is called ___
platypnea
____ refers to cirrhotic patients desaturation greater than 4mmHg or 5% sats from supine to upright

[Cirrhosis]
beta blocker lower ___
portal pressure
What is an alternative to surgery for patients who fail endoscopic and medical treatment?
Transjugular intrahepatic portosystemic shunt (TIPS)
___ are potent splanchnic vasoconstrictor, decreases HR and CO resulting to decreased portal blood flow
- Propranolol
2. Nadolol
