在出生体重极低婴儿脑损害的病因学中,动脉低血压是一个重要的因素,几个研究都表明,为早产婴儿补充血容量可致血压增高,并因此认为低血容量是这些婴儿低血压的常见原因。Robinson等却发现通过输血提高低出生体重婴儿的动脉收缩压(SBP)只能在SBP低于35mmHg时有效。早产婴儿的血容量与动脉血压之间的明确关系尚未建立。本研究就是为了解决这一问题。
Arterial hypotension is an important factor in the etiology of brain damage in infants with very low birth weight, and several studies have shown that increasing blood volume in preterm infants results in an increase in blood pressure and therefore hypovolemia The common reason. Robinson et al. Found that arterial systolic blood pressure (SBP) in infants with low birth weight through blood transfusions was only effective when SBP was below 35 mmHg. The exact relationship between blood volume and arterial blood pressure in preterm infants has not been established. This research is to solve this problem.
