Single lung transplantation in the rabbit: an alternative proposal for the study of preservation devices.
The authors report their standard protocol for single lung transplant in New Zealand rabbit, the anaesthesiological approach consisted of a premedication with Ketamine 35 mg/kg i.m., Atropine sulphate 0.25 mg/kg s.c. and Fentanil 0.1 mg/i.m.; a jugular vein was cannulated and the anaesthesia was carried out administering Ketamine 10-15 mg/kg every 20 min., plus Fentanil 0.1 mg every 30 min. The rabbit was intubated through a tracheostomy, curarized and room air was administered using an appropriate ventilator device. The heart-lung en bloc removal from the donor was performed through a midline sternotomy. The left lung was then separated leaving an adequate cuff of left atrium inclusive of right pulmonary veins which were ligated using a 7-0 thread the graft prepared in this way was then preserved by putting it into the perfusion solutions. The recipient rabbit, after anaesthesia, underwent left pneumonectomy through a left toracotomy the bronchial anastomoses was first performed, followed respectively by the arterial and the atrial sutures. The controlateral pulmonary artery was then clamped and sequential arterial samples were taken from descending aorta previously cannulated to obtain arterial gases tests. The recipient rabbit has been followed up this way no more than 2 hour time, than it was sacrificed.
