25
MOA of octreotide
local splanchnic vasoconstriction and decreased portal inflow less systemic side effects than vasopressin
26
while on octreotide, monitor
hyperglycemia bradycardia HTN arrhythmia abdominal pain vomiting
27
start all patients with variceal bleeding on a short course of
antibiotics
28
preferred antibiotic for variceal bleeding
ceftriaxone (1g/day) x 7 days
29
balloon tamponade
temporarily effective in stopping bleeds rebleeding is common
30
TIPS (transjugular intrahepatic portosystemic shunt)
stents placed between the hepatic and portal veins decreased incidence of rebleeding
31
TIPS is indicated in those
with high risk hemorrhage who fail to achieve hemostasis standard treatment
32
who requires secondary prophylaxis for variceal bleeding? what is recommended?
all patients! combination of EVL and nonselective BB
33
exceptions for secondary prophylaxis for variceal bleeding
patients who received TIPs procedure
34
when assessing a patient with ascites, perform a
abdominal paracentesis
35
what is an abdominal paracentesis
needle is inserted into peritoneal cavity and ascitic fluid is removed
36
after abdominal paracentesis is performed __________ is analyzed for
ascitic fluid cell count with differential, total protein and culture of fluid
37
serum-ascites albumin gradient (SAAG)
serum albumin - ascitic fluid albumin
38
if SAAG is greater or equal to 1.1 g/dl
there is portal HTN
39
if SAAG is less than 1.1 g/dl
consider other causes of ascites
40
grade 1 (mild ascites)
only detected on ultrasound
41
grade 2 (moderate ascites)
moderate symmetric dissension of the abdomen
42
grade 3 (large/gross ascites)
marked distention of the abdomen
43
treatment is recommended for what classifications of ascites?
only grades 2 and 3
44
responsive ascites
can be resolved or limited to grade 1 with diuretic therapy with/wo dietary sodium restriction
45
recurrent ascites
recurs on at least 3 occasions within 12 months despite treatment
46
refractory ascites
cannot be mobilized or unpreventable early recurrence
47
treatment recommendations for ascites
NO alcohol sodium restriction (less than 2g/day) if severe hyponatremia - restrict fluids
48
recommended diuretic therapy for ascites
spironolactone with/wo furosemide in 100:40 ratio
49
goal of diuretic therapy for ascites
attain weight loss of 0.5 kg/day
50
in patients with active bleeds, HE, or renal dysfunction, it may be necessary to
withhold diuretics
51
what to monitor when treating ascites with diuretics?
sodium body weight SCr
52
what is the drug of choice for ascites?
spironolactone
53
an ADR of spironolactone is __________ and if this occurs, it should be switched to ___________-
painful gynecomastia amiloride or eplerenone
54
tense ascites
ascites with large volume of fluid limits activities of daily life
55
for large volume paracentesis, administer
albumin 6-8 g/L of fluid removed
56
for tense ascites, after abdominal paracentesis, start
sodium restriction and diuretics
57
medications to avoid in ascites
ACEIs ARBs NSAIDs amino glycoside antibiotics
58
avoid ___________ in refractory ascites
ACEIs and ARBs
59
refractory ascites
unresponsive to Na restriction and high dose diuretics
60
recommendations for refractory ascites
continue dietary sodium restriction restrict fluids if hyponatremia stop ACEIs/ARBs serial therapeutic paracentesis refer for liver transplantation consider TIPS peritoneovenous shunt
61
diagnosis of SBP
ascitic fluid polymorphonuclear leukocyte over 250/mm3 no evidence of alternative source of infection
62
suspect SBP in patients with ascites presenting with
signs and symptoms of infection
63
therapy for community acquired SBP
third generation cephalosporin (cefotaxime, ceftriaxone)
64
therapy for hospital acquired SBP, critically ill/ICU admission
