What is Cirrhosis?
The end stage of any chronic liver disease
HCV and EtOH are main causes in USA
Results in two major syndromes
– Portal hypertension
– Hepatic insufficiency
Associated with hyperdynamic circulatory state
due to
– Peripheral vasodilation
– Splanchnic vasodilation
Manifestations of Decompensation
Jaundice: hepatic insufficiency
GEV: portal HTN and hyperdynamic circulation
Ascites: sinusoidal HTN and sodium retention due
to vasodilation and neurohumoral systems
HRS: peripheral dilation->renal vasoconstriction
HE: shunting through portosystemic collaterals,
brain edema, and hepatic insufficiency
“Status of the Liver”
1964 – Child and Turcotte publish a system to
predict mortality related to portocaval shunt
surgery in cirrhosis*
1973 – Pugh modified C-T scoring system to
predict mortality related to esophageal surgery for
bleeding varices (replaced ‘nutritional status”
with PT)**
Child’s score = C-P score = CTP score
*Child, CG, Turcotte, JG. Surgery and portal hypertension. In: The Liver and Portal Hypertension, Child, CG (Ed),
Saunders, Philadelphia 1964. p.50.

If The Patient Has Ascites
Development of ascites in cirrhosis is common (60%
over 10yrs); once ascites develops mortality can
reach 50% over the next 2yrs.
Ascites formation is very common in postoperative
setting in patients with cirrhosis/portal HTN due to
liberal use of saline IVF (this can often be the initial
presentation of cirrhosis - - missed pre-op!)
If The Patient Has Ascites
Clues:
– Exam: palpable left/small right lobe,
splenomegaly, caput medusa
– Labs:
Platelets < 175,000
Hepatic insufficiency: albumin <3.8, INR >1.3
– Imaging: nodular liver, splenomegaly
If The Patient Has Ascites
Diagnostic paracentesis:
– No coagulopathy cutoff, need for “reversal”, etc
– Cell count and differential, albumin, and total protein
– If first presentation, concern over infection, or atypical
presentation
Glucose
Bedside culture
Flow cytometry
Simultaneous blood cultures (more later)
LDH
Triglycerides
– Don’t forget serum albumin to determine SAAG
If The Patient Has Ascites
-
-
Make the diagnosis (i.e. recognize it, then analyze the
fluid - - diagnostic paracentesis)
Turn off the NS IV infusion! Think about carrier
solutions for each of the patient’s IV infusions
Sodium restriction: 2gm/day (88mEq)
Oral diuretics: spironolactone alone or
spironolactone/furosemide (100/40 ratio)
Goal: 300-500 ml/d (no edema) vs. 1000 ml/d (w/ edema)
Tense ascites: perform a large volume paracentesis (don’t
forget the albumin - - 6-8 gm per liter ascites removed)
High risk patients with ascites should be placed on SBP
prophylaxis (TP<1 and advanced liver failure)
If The Patient Has Ascites
-
Do NOT use furosemide alone
- Sodium not taken up in LoH absorbed in DCT/CT due
to hyperaldosteronism
-
Do NOT use IV diuretics
No evidence that other diuretics (metolazone,
thiazides, torsemide) offer advantage of
spironolactone +/- furosemide

-
-
-
Most common infection in cirrhosis
Occurs in 10-20% of hospitalized patients with cirrhosis
and ascites
Mortality 10-20% (was 80% when first described)
Early diagnosis is KEY to management and reduction of
complications
Diagnostic paracentesis in any patient with cirrhosis and
ascites:
- Upon hospital admission
- Who develops S/Sx compatible with SBP (abd pain, F/C)
- With worsening renal or liver function
If The Patient Has SBP
-
Diagnosis established:
- Ascites PMN cell count >250
- Ensure bedside cultures collected
- Simultaneous BCx should also be drawn (>50% SBP
also have bacteremia)
- Traumatic tap if >10,000 RBC
-
Subtract 1 PMN for every 250 RBC
If The Patient Has SBP
-
Do not wait on culture results to start Abx
- Cefotaxime most studied (2g q12hr)
- 3rd generation cephalosporine (ceftriaxone 1-2g q12hr)
- “Quinolone” ok if community-acquired, uncomplicated
- Extended spectrum Abx (carbapenems, piperacillin/tazobactam)
if nosocomial SBP
Can change to PO in 48hrs if improving
- 5 day course of Tx minimum, 8 days preferred, thus 7
days reasonable
- Repeat paracentesis/broaden coverage if not improving in
48hrs (expect at least 25% PMN decrease)
-
If The Patient Has SBP
-
Albumin to prevent renal dysfunction (10% vs.
3%) and 3 month mortality (41% vs. 22%)
- 1.5g/kg on day #1 within 6 hours of Dx
- 1.0g/kg on day #3 (reasonable to tailor to renal fx)
-
What NOT to do:
- Avoid aminoglycosides
- No large volume paracentesis
- Avoid diuretics (stop them if Pt is taking them)

Injury (AKI)
AKI occurs in ~19% hospitalized patients with cirrhosis
– Pre-renal ~68% of these
– Intra-renal next most common (ATN vs. GN)
– Post-renal <1%
Hepatorenal syndrome (HRS) is a form of pre-renal
failure: systemic/splanchnic vasodilation and reduced
EAV->renal vasoconstriction
HRS ~33% of pre-renal AKI (1/5 of cirrhotics hospitalized
with AKI)

If The Patient Has AKI
Definition of HRS shifting target
– Consensus conferences: Cr double to >2.5
– Suggested that Tx initiated earlier, with only
1.5-fold increase in Cr from baseline
Key to success is the early recognition and
Tx of this condition
If The Patient Has AKI
D/C medications that decrease blood
volume
– Diuretics
– Lactulose
– Vasodilators
Expand intravascular volume
– Albumin 1g/kg up to max 100g
– NS if over-diuresis is suspected
If The Patient Has AKI
Search for and Tx AKI precipitants
– Infection
– Fluid loss
– Blood loss
If no improvement or continued worsening
– Renal U/S to R/O post-renal AKI
– Urinary sediment to R/O intrinsic AKI
Proteinuria/hematuria suggests GN
Granular/epithelial casts suggests ATN
– Historical clues such as sepsis, hypovolemia, recent
nephrotoxins, contrast dye help sort out ATN vs. HRS
If The Patient Has AKI
OLT is only definitive Tx that provides long-term
survival
Arteriolar vasoconstrictors bridge to OLT
– Terlipressin most studied but not available in USA
– Midodrine plus octreotide most common in USA
Midodrine: start 5-7.5mg PO TID and increase to 12.5-15mg
TID
Octreotide 100mcg SQ TID and increase to 200mcg SQ TID
(continues infusion or used as sole therapy->no benefit)
– Should be coupled with albumin infusions

HE (or portosystemic encephalopathy: PSE) is a
clinical spectrum of reversible abnormalities in
neuropsychiatric function of patients with advanced
liver disease
Continuum of neuropsychiatric alteration:
– Episodic (acute): either precipitated or spontaneous
– Recurrent : 2 or more acute episodes per year
– Persistent (chronic): persistent deficits negatively affect
social/occupational function
– Minimal (subclinical): only found with careful testing

3) Antibiotics: rifaximin 200-600mg TID
4)
5)
6)
No evidence that combo with lactulose is better
Use in patients who can’t tolerate or don’t respond to lactulose
Flumazenil: 0.4-2.0 mg IV (lasts 2-4 hrs only)
Don’t restrict protein (1.0 -1.2 g/kg/day)
If recent TIPS may need reduction/occlusion

Acute Gastrointestinal Bleeding
Liver involved in all 3 systems (coagulation,
fibrinolysis and protein C dep. pathway)
Nearly all proteins involved in hemostasis are produced
in the liver (exceptions: Factor VIII, vWF,
thrombomodulin)
Impaired production and clearance effect fibrinolytic
system (dec. clearance t-PA, PAI-1)
Clinical importance of PLT dysfxn in cirrhosis unclear;
thrombocytopenia is due to splenic sequestration
Acute Gastrointestinal Bleeding
Overall have impaired thrombin generation and less
stable fibrin structure with increased fibrinolysis
(“defective hemostatic plug”)
Hemostatic disturbances in cirrhosis are similar to
those described for DIC
Acute Variceal Hemorrhage
Acute variceal hemorrhage mortality 15-20%
Acute Variceal Hemorrhage
Volume expansion: colloids over crystalloids
– SBP 90-100mm Hg
– HR<100 bpm
Transfusion of blood products to maintain
– Hgb ~8g/dl (higher increases re-bleeding/mortality)
– Platelets ~50,000
– INR to 1.3
Consider prophylactic intubation if massive
bleeding and decreased LOC
Acute Variceal Hemorrhage
Initiate somatostatin analog (octreotide) as soon
as diagnosis suspected
– 50 mcg IV bolus followed by 50 mcg/hr infusion
– Continued for 5 days
Antibiotic prophylaxis for 3-7 days with cipro
vs. ceftriaxone (ascites, PSE, bilirubin >3,
malnutrition)
Endoscopic evaluation within 12 hours
Acute Variceal Hemorrhage
Sengstaken Blakemore tube: 2 balloons
Linton tube: large gastric balloon
Control hemorrhage in >80%
Mortality is 20% due to complications
– Aspiration
– Migration
– Perforation
Re-bleeding after deflation almost universal
Only used in patients in whom shunt planned within 24
hours
Intubation strongly recommended

Pain Management
Short-acting analgesics (and sedatives) are
always preferred in cirrhotics
Opiods are metabolized via hepatic
glucuronidation (and oxidation); thus clearance
is impaired (potential for toxic metab. accum.)
NSAIDs impair renal fxn in cirrhosis, as well as
decreasing natriuresis (effect on ascites therapy)
NSAIDs increase risk for variceal bleeding (in
addition to standard risk for GI toxicity/PUD)
Pain Management
Recommendations:
1) Do not use NSAIDs (even COX-2’s) !!
2) Fentanyl is the opiod of choice in cirrhosis (long
acting methadone is safe as well)
3) If using morphine, oxycodone or demerol decrease
the dose by 50% and increase dosing interval 2-fold
4) Acetaminophen is the analgesic of choice !
(maximum dose 2 gm/day); but use caution in
cirrhotics who are actively drinking EtOH
5) Don’t forget about analgesic combinations containing
acetaminophen

Risk Factors for M&M in Cirrhotics
Characteristics of the Patient:
- Child’s classification (C>B>A)
- Presence of ascites or encephalopathy
- Presence of jaundice, hypoalbuminemia and/or prolonged PT
(>2.5-3 sec above normal, not correctable w/ Vit. K)
- Presence of portal hypertension
- On-going infection (i.e. SBP, cellulitis)
- Anemia, hypoxemia or malnutrion
Type of Surgery:
- Emergent
- Abdominal (esp. gastrectomy, colectomy, chole)
- Any cardiac surgery
- Hepatic resection
Perioperative Mortality and CPT
1984 – periop. mortality (non-shunt, abd.
surgery); Child’s A = 10%, B = 31%, C = 76%
1997 – periop. mortality (non-shunt, abd.
surgery); Child’s A = 10%, B = 30%, C = 82%
2003 – periop. mortality (non-shunt, abd.
surgery); Child’s A = 7.1%, B = 23%, C = 84%
MELD For Pre-operative Risk Stratification
Retrospective 1980-2004, N=773 (675 MELD<15), ave. age 61
Primary Endpoint: MELD as a predictor of peri-op mortality in
non-transplant surgery
Secondary Endpoint: Does the type of surgery matter?
’93-’04 vs. ’80-’92 showed a trend toward better outcomes, but
NS overall
“Other” vs. “Foregut” (hepatobiliary, pancreatic,UGI) surgery
trended to better overall outcomes
Multivariate Analysis: Age (in increments of 10yr) increased
risk 1.5x (30d) and MELD (increments of 5pts) increased
mortality risk 2.2x (1.9-2.5) at 30days
