Abstract
The function of six porcine left lung allografts was studied after pulmonary (140 mL/kg) and bronchial (50 mL/kg) artery perfusion with Perfadex (Kabi Pharmacia, Uppsala, Sweden) at room temperature, followed by 24-hour storage of the lungs in an atelectatic state in 6 degrees to 8 degrees C Perfadex, which is a low-potassium-dextran solution. Left lung transplantation was done followed by right pneumonectomy, thereby making all the animals 100% dependent for their survival on the transplanted lungs. The pigs (mean weight = 56 kg, range = 51 to 58 kg, n = 18; 6 donors, 6 recipients, and 6 sham operated) were ventilated with a volume-controlled ventilator (20 breaths/min, 500 mL tidal volume, 8 cm H2O positive end-expiratory pressure,...

The pigs (mean weight = 56 kg, range = 51 to 58 kg, n = 18; 6 donors, 6 recipients, and 6 sham operated) were ventilated with a volume-controlled ventilator (20 breaths/min, 500 mL tidal volume, 8 cm H2O positive end-expiratory pressure, inspired oxygen fraction = 0.5). All the transplanted animals were in good condition throughout the 24-hour observation period with arterial oxygen tensions around 25 kPa (188 mm Hg) and arterial carbon dioxide tensions around 5 kPa (38 mm Hg). The mean pulmonary arterial pressure was around 30 mm Hg, and the pulmonary vascular resistance around 500 dyn.s.cm-5; neither showed any tendency to change with time. After 24 hours the inspired oxygen fraction was increased to 1.0 and the arterial oxygen tension increased to 43.3 +/- 5 kPa (325 +/- 38 mm Hg) (mean +/- standard error of the mean; n = 6). A sham operation (bilateral thoracotomy, right pneumonectomy) was done in 6 pigs, which were followed up for 24 hours.(ABSTRACT TRUNCATED AT 250 WORDS) (Less)
