Objective To analyze the blood gas analysis before extubation related to early withdraw venti-lator in infants with congenital heart disease.Methods Collecting the blood gas analysis datas before extubation of infants with congenital heart disease who were treated with CICU in our hospital from 2014. 01.01 to 2017.01.01, To analyze the relationship between early withdraw ventialtor and the blood gas analysis before extubation. Re-sults 1.Univariate analysis showed that infants with congenital heart disease early postoperative rate of weaning were related to blood gas analysis before extubation with PH,HCO3-,Lac-,SaO2,A-aDO2,respiratory index and oxygenation index(P<0.05).2.The results of non conditional logisitic regression analysis showed that PH,HCO3-and Lac- were independent factors,the value of OR(95%CI) were 50.1(80-311),1.51(1.12-2.02) and 0.18 (0.05-0.65). Conclusion In infants with congenital heart disease before extubation SaO2high,A-aDO2≤ 100 mmHg,respiratory index low and oxygenation index high were the important factors of postoperative early weaning;The PH,HCO3-and Lac-were independent factors,even though early withdrawal unit blood gas analysis before ex-tubation the index is inferior to late withdrawal unit's,it can also achieve early weaning in the basic normal value range.
