BACKGROUND:
Anesthesia for lung transplantation: intraoperative complications and long term results.
METHODS:
52 patients were scheduled for 16 single lung transplantations (SLT) (9 fibrosis and 7 emphysema) and 36 bilateral sequential lung transplantations (DLT) (4 bronchiectasis, 6 emphysema, 3 fibrosis, 22 cystic fibrosis and 1 pulmonary hypertension). Anesthesia was induced with propofol or midazolam, and fentanyl or alfentanil. As muscle relaxant vecuronium bromide was used. Anesthesia was maintained with isoflurane, fentanyl in boluses or sufentanil continuous infusion in O2 100%. Prostaglandin E1 (20-300 ng/kg/min), inhaled nitric oxide (10-40 ppm), dobutamine (5-15 mcg/kg/min), norepinephrine (0.05-3 mcg/kg/min) and ephedrine (5-10 mg per bolus) were used for hemodynamic management. In 2 patients inhaled areosolized prostacyclin were administered.
RESULTS:
Mean pulmonary arterial pressure (mPA) and pulmonary vascular resistance (PVRI) increased after pulmonary artery clamping during first lung (mPA: 3347 nel DLT, 3643 nel SLT; PVRI; 375488 nel DLT, 377420 nel SLT) and second lung implantation (mPA: 3746; PVRI: 263553) and decreased after reperfusion of the first (mPA: 4737 nel DLT, 4329 nel SLT; PVRI: 488263 nel DLT, 420233 nel SLT) and the second lung (mPA: 4629; PVRI: 553260). Only in 9 cases (7 DLT and 2 SLT) C-P bypass was used.
CONCLUSIONS:
With a strong drug support with pulmonary vasodilators, positive inotropic and systemic vasoconstrictor drugs, in most patients we transplanted C-P bypass can be avoided. Intraoperative deaths were not observed. Two years actuarial survival is 65% for DLT and 60% for SLT.
