title: [Combined lung and liver transplantation. Anesthesiologic management].
abstract: A 53-year-old man with alpha-1-antitrypsin deficiency had an 8-year history of progressive dyspnoea and two episodes of bleeding oesophageal varices with liver decompensation. After the diagnosis of terminal pulmonary emphysema (Fig. 1) and liver cirrhosis with progressive liver failure was made, he was accepted for combined lung and liver transplantation. METHODS. Anaesthesia was induced with thiopentone and fentanyl and maintained with fentanyl, midazolam, and isoflurane. After relaxation with succinylcholine, the patient's trachea was intubated with a left endobronchial double-lumen tube. Haemodynamic monitoring included arterial, central-venous, pulmonary-artery, and capillary-wedge pressures and cardiac output measurement. Ventilatory monitoring consisted of pulse oximetry, side-stream spirometry, and continuous measurement of arterial and mixed-venous blood oxygen saturation with fibreoptic catheters. A left single-lung transplantation was performed under one-lung ventilation without cardiopulmonary bypass. Prostacyclin was infused to reduce pulmonary vascular resistance. The transplant was ventilated separately with 50% oxygen and positive end-expiratory pressure of 8-10 cm H2O, and then liver transplantation was carried out. The institution of veno-venous bypass during the anhepatic phase failed because of portal-vein and axillary-vein thrombi. RESULTS. Total operation time was 6 h 30 min. Clamping of the left pulmonary artery lasted 45 min and the duration of the anhepatic phase was 92 min. Ventilation and oxygenation during lung transplantation caused no problems (Table 1). Clamping of the left pulmonary artery caused a slight increase in pulmonary vascular resistance (104 to 124 dyn.s.cm-5) and mean pulmonary artery pressure (25 to 27 mm Hg) without a decrease in cardiac index (Table 2). During the anhepatic phase with exclusion of the portal vein and inferior vena cava, a marked decrease in cardiac index (-27.2%) was seen (Table 4). The operation required substitution with 10 units packed red blood cells, 12 units fresh frozen plasma, and 5 platelet concentrates. The post-operative course showed normal liver graft function (Table 5). Acute pulmonary rejection on the 7th day was treated successfully with methylprednisolone. The patient's trachea has extubated 10 days after transplantation and he was discharged from the intensive care unit 2 weeks later. CONCLUSION. The management of this combined lung and liver transplantation was performed according to the experience with isolated lung and liver transplants in our hospital. Aggressive haemodynamic and ventilatory monitoring, including systemic and pulmonary arterial fibreoptic catheters, seems of particular importance in such high-risk procedures.
