Influence factors on the enflurane uptake at the lung of child suffering from congenital heart diseases / 中华麻醉学杂志

ABSTRACT

Objective To study the influence factors on the enflurane uptake in child with congenital heart disease(CHD).Methods Sixty children aging less than 5 years with CHD were randomly divided into four groups in group A 15 children with atrial septal defect(ASD)or ventricular septal defect (VSD) inhaled enflurane before and after CPB;in groups B 15 children with ASD or VSD did only after CPB,in group C 15 children with tetralogy of fallot (F4) did before and after CPB;in group D 15 children with F4 did only after CPB.The concentration of enflurane (F I) was kept at 0.5%.Following inhalation of enflurane,the end tidal alveolar concentration (F E) was measured in 30 min and the time of uptake equilibrium (Tue,F E/F I=1) was recordcd.Results In group C,Tue before CPB was shorter than that before CPB and after CPB in group A,that in group B and group D (P
