新生儿血清胆红素超过15毫克%以上,常可出现神经毒性。并可引起核黄疸,导致新生儿死亡或留有后遗症。为降低血清胆红素浓度,防止核黄疸发生,过去一直沿用的方法是换血,但手续复杂,且有1～55%的危险性,在某些婴儿血清胆红素甚至仅为9毫克%,亦可发生核黄疸。对这类婴儿换血的标准亦难以掌 Neonatal serum bilirubin more than 15 mg%, often appear neurotoxic. And can cause nuclear jaundice, leading to neonatal death or sequelae. In order to reduce the concentration of serum bilirubin and prevent the occurrence of nuclear jaundice, the method used in the past is to change the blood. However, the procedures are complicated with a risk of 1 to 55%. In some babies, the serum bilirubin is even only 9 mg% Nuclear jaundice can also occur. The standard for transfusing such babies is hard to come by
