该研究目的为评估对接受特护的极低出生体重儿(<1500 g)进行标准红细胞输注所产生的心血管呼吸系统短期效应。研究对象为有动脉插管的37名婴儿(平均出生体重:920±230 g,胎龄27.8±2.1周,研究时年龄6.1±3.9 d),基于临床的判断对他们输注了10 ml/kg 的压缩红细胞。有动脉导管未闭和(或)正接受影响心肌 The purpose of this study was to evaluate the short-term effects of cardiovascular respiration on standard RBC transfusions in very-low birth weight infants (<1500 g). Thirty-seven infants (mean birth weight: 920 ± 230 g, gestational age 27.8 ± 2.1 weeks, study age 6.1 ± 3.9 days) were enrolled and were infused with 10 ml / kg on clinical judgment Of compressed red blood cells.
