20
Q

What medication class should we avoid in patients with cirrhosis?

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

24
Q

Max ratio of spironolactone:furosemide

25
Second line option for ascites management
Paracentesis TIPS
26
Aldosterone antagonists _____ potassium and loop diuretics ____ potassium levels
Increase Decrease
27
Both, spironolactone and furosemide, can cause
AKI
28
What is given for pts that get more than 5 L removed via paracentesis?
ALBUMIN (helps retain fluid in vasculature)
29
If more than 5L is removed via paracentesis, how much albumin do we give?
6-8 g/L of fluid removed of 25% albumin
30
What is monitored for ascites tx?
S/Sx of ascites Renal function Potassium (goal: 3.5-5)
31
What are esophageal varices?
Compensatory "varices" or small offshoots -Dilation of EV can cause variceal bleeding
32
Variceal bleeding prophylaxis
NSBB EVL ***CHOOSE 1 OR THE OTHER***
33
Titrate NSBB to a HR goal of ____, but maintain a SBP ____
< 60 bpm > 90 mmHg
34
NSBB options for EV
Nadolol Propranolol Carvedilol
35
Are PPI recommended for variceal bleeding?
NO; only used in non-variceal bleeding
36
Upon presentation of EV bleeding, what should be done?
1. Transfusion (Hgb > 7) 2. Octreotide 2-5d 3. Ceftriaxone 7d ***Until we can get surgery
37
What surgery is done for EV bleed?
EVL
38
After EVL, what is done?
Secondary prophylaxis with NSBB AND EVL
39
Underlying patho of HE
Ammonia accumulation -- leads to neuronal dysfunction and HE
40
S/Sx of HE
Jaundice precedes delirium, convulsions
41
Recommended tx for acute management of HE
Lactulose 25 ml BID
42
We adjust lactulose to ___ BM/day
3
43
Diagnosis for SBP
Therapeutic paracentesis **PMN > 250 cells/mm3
44
PMN equation
PMN = WBC from fluid x (% neutrophils)
45
SBP tx
Ceftriaxone IV x 7d + Albumin IV
46
After intial tx for SBP, what is secondary prophylaxis protocol?
Bactrim (SMX/TMP) QD indefinitely Ciprofloxacin QD
