Abstract

INTRODUCTION. The haemodynamic and oxyforetic modifications induced by continuous infusion (c.i.) of Prostaglandin E1 (PGE1) and Nitroglycerin (NG) during experimental lung transplantation have been studied. METHODS. Twenty lung transplants have been performed on pigs (Landrace). Haemodynamic monitoring consisted of ECG, femoral cannulation for arterial pressure and Swan Ganz catheter. Continuous infusion of drugs started during pneumonectomy. Data have been collected in phase 1: after the induction of anaesthesia; in phase 2: 30 min after the start of pulmonary vasodilation in one lung ventilation with left pulmonary artery clamped; in phase 3: 30 min after lung revascularization; in phase 4: at the end of the surgery. The animals have been divided in two groups. Group A consisted of 10 cases treated with 50 ng/kg/min in phase 2 and 25 ng/kg/min in phase 3 and 4 of PGE1; group B consisted of 10 cases treated with 1 ncg/kg/min in phase 2 and 0.5 ncg/kg/min in phase 3 and 4 of NG. RESULTS. In phase 2 and 4 PA, RVSWI, PRVI increased in group B more than in group A (p <0.05); in phase 3 PA, PAWP increased in group B more than in group A (p <0.05). DISCUSSION. In our experience PGE1 has shown to be a stronger pulmonary vasodilator than NG. PGE1 can be considered the drug of choice for pulmonary vasodilation in experimental single lung transplantation, even if more investigations are needed for reaching the real goal of this procedure.
