Preoperative risk evaluation • Circulatory (hyperkinetic profile with low SVR, high venous compliance, coronaropathy or cardiomoypathy, pulmonary hypertension) • Ventilatory (Hypoxemia, intrapulmonary shunt, restrictive syndrome (ascite, pleural effusion)
Preoperative risk evaluation • Circulatory (hyperkinetic profile with low SVR, high venous compliance, coronaropathy or cardiomoypathy, pulmonary hypertension) • Ventilatory (Hypoxemia, intrapulmonary shunt, restrictive syndrome (ascite, pleural effusion) • Renal (hypovolemia, hepatorenal syndrome) • Cerebral (encephalopathy, cerebral edema) • Coagulation (hypo-/ hypercoagulability, fibrinolysis) • Pharmacokinetic/dynamic changes to drug effects
Choice of anesthetic agents/techniques • Risks of regional anesthesia • Use intravenous anesthetics with elimination independent from cytochrome P450 activity (Propofol AIVOC, ketamine, etomidate, fentanyl, sufentanil, remifentanil, atracurium/cisatracurium) • Volatile anesthetics: desflurane/sevoflurane • Maintain hemodynamic stability +++ • MONITOR and TITRATE+++
Patient Risk/benefit balance of anesthesia and surgery Anesthesiologist Surgeon Hepatologist/ Gastroenterologist
Intraoperative period • Short acting anesthetics • Postoperative analgesia • Prevention of PONV • Reversal of muscle relaxants • Maintenance of normovolemia, hemoglobin levels • Prevention of awareness • Maintenance of normothermia • Maintain oxygenation • Restrictive fluid therapy • Avoid hyperglycemia • Start postoperative rehabilitation

Anesthesia for endoscopic procedures. • High risk anesthesia +++ • Outside the OR • Inhalation of gastric content • Obstructive hypoxemia • Hemorrhage and perforation • Pulmonary hypertension
Indications for endotracheal intubation • Esophageal varices treatment (inhalation risk+++) • Radiofrequency (painful procedures) • Other indications: • Long duration procedure (> 1h)) • Comorbidities (obesity, major ascite, diabetic dysautonomia)
Conclusion • Cirrhotic patients are at high risk of postoperative morbi-mortality • Discuss the risk/benefit balance of surgery and anesthesia • Maintain hemodynamic stability (monitor, titrate) • There is no « minor » anesthesia
