摘要
为探讨球囊房隔造口术(BAS)及前列腺素E1(PGE1)对婴儿完全性大动脉转位(TGA)外科根治术前血液动力学的调整作用,对32例年龄2~56天,平均26天的TGA患儿行BAS,对其中11例于BAS前给予PGE1,然后进行血液动力学观察。结果:BAS后动脉血氧饱和度(SaO2)由0.53±0.14上升至0.74±0.11。30例患儿左右心房压差均<0.27kPa(1kPa=7.5mmHg)。单纯TGA术后24个月内左室压力<5.30kPa。PGE1应用后SaO2由术前0.60±0.19上升至0.86±0.05。心导管检查测得左右室压力比为0.86。提示,BAS和PGE1的应用可缓解新生儿TGA低氧血症及维持其左右心室良好的压力比值。
The study was designed to understand the effects of balloon atrial septostomy (BAS) and prostaglandin E 1 (PGE 1) infusion on infants with complete transposition of great arteries before corrective surgery. After BAS was performed on 32 cases at an average age of 26 days and PGE 1 administered in 11 of them, the hemodynamics were observed in these patients. It was found that BAS resulted in a significant increase in arterial oxygen saturation (SaO 2) from 0 53±0 14 to 0 74±0 11 ( P < 0.001), with a decreased pressure gradient between left and right atria less than 0.27 kPa and left ventricular systolic pressure less than 5.3 kPa within 24 months in simple TGA. The arterial SaO 2 increased from 0.60±0.19 to 0.86±0.05, with a ratio of left to right ventricular systolic pressure more than 0.86 after PGE 1 infusion before BAS. The study indicates that, after BAS infants with TGA can survive until an appropriate age for atrial switch operation, and PGE 1 adminstration can relieve hypoxemia and keep a satisfactory ratio of left to right ventricular pressure for arterial switch procedure in the newborns with TGA.
