NSAIDs

21
Q

Non-pharm options for ascites management

A

Na+ restriction (< 2 grams/day)
Assess MELD score

22
Q

First line option for ascites

A

Aldosterone antagonist (spironolactone) + loop diuretic (furosemide)

23
Q

Recommended ratio of spironolactone: furosemide

A

100:40

24
Q

Max ratio of spironolactone:furosemide

A

400:160

25

Paracentesis
TIPS

26
Q

Aldosterone antagonists _____ potassium and loop diuretics ____ potassium levels

A

Increase
Decrease

27
Q

Both, spironolactone and furosemide, can cause

A

AKI

28
Q

What is given for pts that get more than 5 L removed via paracentesis?

A

ALBUMIN (helps retain fluid in vasculature)

29
Q

If more than 5L is removed via paracentesis, how much albumin do we give?

A

6-8 g/L of fluid removed of 25% albumin

30
Q

What is monitored for ascites tx?

A

S/Sx of ascites
Renal function
Potassium (goal: 3.5-5)

31
Q

What are esophageal varices?

A

Compensatory “varices” or small offshoots
-Dilation of EV can cause variceal bleeding

32
Q

Variceal bleeding prophylaxis

A

NSBB
EVL
CHOOSE 1 OR THE OTHER

33
Q

Titrate NSBB to a HR goal of ____, but maintain a SBP ____

A

< 60 bpm
> 90 mmHg

34
Q

NSBB options for EV

A

Nadolol
Propranolol
Carvedilol

35
Q

Are PPI recommended for variceal bleeding?

A

NO; only used in non-variceal bleeding

36
Q

Upon presentation of EV bleeding, what should be done?

A
  1. Transfusion (Hgb > 7)
  2. Octreotide 2-5d
  3. Ceftriaxone 7d
    ***Until we can get surgery
37
Q

What surgery is done for EV bleed?

A

EVL

38
Q

After EVL, what is done?

A

Secondary prophylaxis with NSBB AND EVL

39
Q

Underlying patho of HE

A

Ammonia accumulation – leads to neuronal dysfunction and HE

40
Q

S/Sx of HE

3

43
Q

Diagnosis for SBP

A

Therapeutic paracentesis
**PMN > 250 cells/mm3

44
Q

PMN equation

A

PMN = WBC from fluid x (% neutrophils)

45

46
Q

After intial tx for SBP, what is secondary prophylaxis protocol?

A

Bactrim (SMX/TMP) QD indefinitely
