Abstract:
Objective To investigate the merit and feasibility of vasoactive drugs by the double atrial infusion in children with congenital heart disease combined with pulmonary hypertension.Methods Ninety cases of congenital heart disease combined with pulmonary hypertension were randomly selected.One group(45 cases) was infused by double atrialadministration,which left atrium for catecholamines,and right atrial infusion for highly targeted expansion of pulmonary vascular drugs,such as prostaglandin E1.Another group(45 cases) was infused through the right atrium by a central venous to catecholamines and pulmonary vascular dilatation drugs.Cardiac output(CO) and cardiac index were measured by thermal dilution method and systemic vascular resistance and pulmonary vascular resistance(PVR) were calculated.Results Three cases were dead in early postoperative period(1 week),which were central intravenous group.2 cases with total anomalous pulmonary venous drainage had low co after operation,include 1 case through the left atrium,and the other case through central venous administration,and were recovered.There was no long-term mortality.There was no significant difference in CPB time,blocking time,the amount and timing of vasoactive drugs in two groups (P ＞ 0.05).Conclusion Double atrial infusion of vasoactive drugs can significantly reduce the mean pulmonary artery pressure and pulmonary vascular resistance,and increase CO,which is better than the traditional central intravenous methods.The treatment method is of very important significance.Thus double atrial infusion is safe and feasible.
