ABSTRACT
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.
ABSTRACT
Objective To analyze the preoperative related factors of early weaning of infants with congenital heart disease after operation. Methods From January ,2014 to January ,2017 in Pediatric Cardiology CICU , infants with congenital heart disease were selected as research objects. The clinical data were retrospectively collect ed and the relationship between preoperative influencing factors and postoperative early weaning were analyzed. Early weaning meant mechanical ventilation time was shorter than 24 h and late weaning meant longer than 24 h. Results Single factor analysis showed that early weaning success rate was related to preoperative cardiac function grade 1,NNIS grade 0~1,ASA grade 1,no lung infection and no or mild pulmonary hypertension(average P<0.05). Non conditional logistic regression analysis showed that preoperative heart function grade 1 was an indepen-dent influencing factor,with OR value(95%CI)of 3.9(1.9~7.7). Conclusions In infants with congenital heart disease,preoperative heart function grade 1,NNIS grade 0 ~ 1 ,ASA grade 1,no lung infection and no or mild pulmonary hypertension benefit early withdrawing of ventilator and preoperative cardiac function grade 1 is an inde-pendent factor for early weaning.
