Anesthesia for liver transplantation in patients with arterial hypoxemia.
Arterial oxygenation during anesthesia and time of postoperative mechanical ventilation were investigated in 17 patients with chronic liver disease who underwent liver transplantation. Six patients had arterial hypoxemia (PaO2 64 +/- 3 mm Hg) and the other 11 patients had normal PaO2 (105 +/- 5 mm Hg) before transplantation. None of the patients were smokers and all had normal preoperative pulmonary X-ray and spirometry. During transplantation, PaO2 increased in both groups, but PaO2 was still approximately 20% lower and PA-aO2 was 40%-60% higher in the hypoxemic group than in the normoxemic patients (P less than 0.05). The median postoperative time on mechanical ventilation was three times longer in the hypoxemic group (56 h) than in the normoxemic patients (18 h; P = NS). Number or severity of postoperative complications and outcome did not differ between the two groups. It is therefore suggested that patients with arterial hypoxemia without overt lung disease should also be accepted for liver transplantation.
