Cirrhosis and the patient with liver disease
Stem
A 58-year-old man, 76 kg, with alcohol-related cirrhosis is referred for elective repair of a symptomatic umbilical hernia. He has moderate ascites on diuretics, mild confusion treated with lactulose, and exertional dyspnea. Labs: bilirubin 2.6 mg/dL, albumin 2.8 g/dL, INR 1.8, creatinine 1.3 mg/dL, sodium 131, platelets 68,000. Room-air SpO2 is 93%.
Question
Should he have this operation now, and if he does, how will you plan the anesthetic?
Ideal answer
HeadlineNot now: Child C, MELD around 20, so I defer this elective repair, agree it with surgeon and hepatologist, and refer him to a transplant center.
- MELD and Child-Pugh first: Child A or MELD under 10 tolerates elective surgery; Child C or MELD above 20, only urgent, life-saving surgery.1 Ascites, encephalopathy, bilirubin 2.6, albumin 2.8, INR 1.8 make him Child C.
- If urgent, optimize first: ascites, encephalopathy, renal function, electrolytes, nutrition; dyspnea and low saturation mean an echo for portopulmonary hypertension and hepatopulmonary syndrome.
- INR left alone, because it overstates bleeding risk in rebalanced hemostasis; bleeding treated by viscoelastic testing.
- Liver-independent drugs: cisatracurium and remifentanil, all else reduced, titrated, no benzodiazepines. Tense ascites and varices: full stomach, rapid sequence, gentle orogastric tube.
Watch for: hepatic blood flow: MAP and cardiac output up; no hypotension, hypoxia or high airway pressures.
Breaking down the answer
- Decide whether to operate — perioperative mortality tracks severity, and the examiner grades judgment about proceeding. Child-Pugh uses bilirubin, albumin, INR, ascites and encephalopathy; MELD uses bilirubin, INR, creatinine and sodium and predicts 30- and 90-day surgical mortality.
- The mortality numbers — risk climbs steeply through the teens. Abdominal surgery: Child A ~10%, B ~30%, C ~76–82% in older series;2 MELD 12–15 carries about 25% and 16–20 about 44% 30-day mortality.3
- Rebalanced hemostasis — pro- and anticoagulants both fall; INR overstates bleeding risk, and they also thrombose. INR thresholds are not evidence-based and plasma raises portal pressure; for bleeding or high-risk procedures: fibrinogen above 120 mg/dL, platelets above 50,000, by TEG or ROTEM.4
- Hyperdynamic circulation — high cardiac output and low SVR from nitric oxide and splanchnic vasodilation blunt vasoconstrictor response, so I start norepinephrine and vasopressin early.
- Lungs — hepatopulmonary syndrome causes intrapulmonary shunting, hypoxemia and platypnea; oxygen helps. In portopulmonary hypertension, a mean PA pressure above 35 mmHg needs vasodilator therapy before transplant, and 45 mmHg or more is an absolute contraindication;5 I avoid hypoxia, hypercarbia and acidosis.
- Ascites — I drain large ascites before induction when it impairs ventilation; above 5 L removed, albumin 6–8 g per liter prevents post-paracentesis circulatory dysfunction.6
- Drugs — a larger volume of distribution and lower albumin mean a normal or larger initial dose with prolonged duration; benzodiazepines precipitate encephalopathy.3
Follow-up question
Three weeks later the hernia incarcerates and he comes for urgent repair. After 2 L of ascites drains through the hernia sac, the MAP falls to 55 and the field begins to ooze. What do you do?
Follow-up answer
HeadlineVasodilation from the loss of abdominal pressure in a hyperdynamic patient, plus a bleeding problem not yet characterized; I tell the surgeon.
Albumin and norepinephrine, vasopressin if needed; a gas, hemoglobin, ionized calcium and TEG. Low fibrinogen gets cryoprecipitate; weak clot strength, platelets; plasma only for a prolonged R time with active bleeding, because large-volume plasma raises portal pressure and worsens bleeding.4 I reassess pressure and the field. Postoperatively I watch for hepatorenal syndrome, treated with albumin and a vasoconstrictor such as terlipressin or norepinephrine, and for encephalopathy, treated with lactulose and rifaximin.
Pitfalls that cost points
- Treating low SVR with fluid alone.
- Correcting a pre-procedure INR with plasma.
Rapid-fire
Q: Why is cisatracurium preferred? A: Hofmann elimination is independent of the liver and kidney; rocuronium and vecuronium are prolonged.
Q: Why are these patients hyponatremic? A: Splanchnic vasodilation triggers ADH release and water retention; I correct no faster than 8 mEq/L per day because of osmotic demyelination.
Q: Why does the volatile choice matter little? A: Sevoflurane, desflurane and isoflurane all maintain hepatic blood flow; halothane is the one that reduces it.
Q: Is acetaminophen safe? A: Yes, at a reduced ceiling of about 2–3 g per day,3 and it is better than NSAIDs, which precipitate renal failure and bleeding.
