Blood volume and systolic blood pressure (SBP) were measured in 43 preterm infants. Mean (SD) blood volume was 83 (19) ml/kg (range 48-119) and SBP 50 (9) mm Hg (range 34-69), showing a significant overall relationship. Blood volume in infants with SBP > 60 mm Hg (110 (6) ml/kg) was significantly higher than in infants with SBP 40-60 mm Hg (78 (16) ml/kg) and in infants with SBP < 40 mm Hg (75 (10) ml/kg). In conclusion, SBP is of limited value in detecting hypovolaemia in very low birthweight infants.
对43名早产儿测量了血容量和收缩压（SBP）。平均（标准差）血容量为83（19）ml/kg（范围48 - 119），收缩压为50（9）mmHg（范围34 - 69），显示出显著的总体相关性。收缩压>60 mmHg的婴儿血容量（110（6）ml/kg）显著高于收缩压在40 - 60 mmHg的婴儿（78（16）ml/kg）和收缩压<40 mmHg的婴儿（75（10）ml/kg）。总之，收缩压在检测极低出生体重儿低血容量方面价值有限。
