Eight children (age 4 months - 9 years) were studied after surgical correction of congenital heart defects. Sternum closure reduced mean arterial pressure by 7% (p less than 0.05) and cardiac output by 14% (p less than 0.01), and increased central venous pressure by 2 mmHg (p less than 0.05). There was evidence of a decrease in intracardiac blood volume. It is suggested that the circulatory effects of sternum closure were due to increased pressure outside the heart, which reduced the pressure across the heart wall and the end-diastolic volume.
八名先天性心脏缺陷手术矫正后的儿童（年龄4个月至9岁）接受了研究。胸骨闭合使平均动脉压降低了7%（p<0.05），心输出量降低了14%（p<0.01），并使中心静脉压升高了2 mmHg（p<0.05）。有证据表明心内血容量减少。提示胸骨闭合的循环效应是由于心脏外压力增加，这降低了跨心脏壁的压力和舒张末期容积。
