[Treatment of pulmonary hypertension in the immediate period after general anesthesia and surgical correction of patent ductus arteriosus and heart septal defects].

Surgical correction of the arterial duct and defects of the cardiac septa is followed in the nearest period after surgical correction by lung hypertension which considerably aggravates the postoperative period. The observation of 74 patients has shown that infusions of 1% solution of phosphobion (0.05 mg/kg/min) in the pulmonary artery decrease the pressure in the pulmonary artery, pulmonary-vascular resistance, make the incidence of disturbed heart rate less frequent, reduce the concentration of noradrenaline and prostaglandins.
