Clinical effect of red blood cells transfusion on newborns with neonatal respiratory distress syndrome / 中国输血杂志

ABSTRACT

【Objective】 To analyze the risk factors related to the number of RBCs transfusion in neonates with neonatal respiratory distress syndrome (NRDS), and to explore the complications and the predictive indicators related to the increase of RBCs transfusion frequency. 【Methods】 NRDS newborns admitted to our hospital from January 2017 to January 2019 were selected and divided into three groups according to the number of RBCs transfusion, namely, non-transfusion group, 1~ 2 times group, and ≥3 times group. The clinical data and complications of the three groups were compared, and the risk factors leading to the increase of the number of blood transfusion were analyzed. 【Results】 Such factors as maternal age ≥35 years old, gestational age, birth weight, hemoglobin(Hb) at admission, non-invasive ventilation time, hospitalization time in neonatal intensive care unit(NICU), total enteral feeding time affected the blood transfusion frequency of the three groups(χ2=14.24, F=28.44, 41.70, 60.05, 3.83, 5.97, 4.40, P<0.05). The incidence of necrotizing enterocolitis (NEC), septicemia and feeding intolerance in blood transfusion ≥3 times group was significantly higher than that in 1~2 times group and non-transfusion group (χ2=19.30, 18.68, 6.98, P<0.05). Multivariate logistic regression analysis showed that birth weight, Hb at admission, length of stay in NICU and time of reaching total enteral feeding were independent risk factors for≥ 3 times of blood transfusion (OR=-3.942, -0.186, 0.530, 0.324, P<0.05). The ROC curve showed that birth weight and Hb at admission were effective in predicting blood transfusion ≥3 times, and the area under the ROC curve were 0.846 and 0.802, respectively, and the truncation values were 2.315 kg and 157.5 g/L. 【Conclusion】 Feeding intolerance, NEC and septicemia are the complications of the increased transfusion frequency in children with NRDS, and birth weight and hemoglobin at admission are effective in predicting blood transfusion ≥ 3 times.
