Rapid blood loss with circulatory shock is dangerous for the preterm infant as cardiac output and oxygen-carrying capacity are simultaneously imperilled. This requires prompt restoration of circulating blood volume with emergency transfusion. It is recommended that clinicians use both clinical and laboratory responses to guide transfusion requirements in this situation. For preterm infants with anemia of prematurity, it is recommended that clinicians use a restrictive algorithm from one of two recently published clinical trials. Transfusion outside these algorithms in very preterm infants is not evidence-based and is actively discouraged.
快速失血伴循环休克对早产儿是危险的，因为心输出量和携氧能力同时受到威胁。这需要紧急输血以迅速恢复循环血量。建议临床医生根据临床和实验室反应来指导这种情况下的输血需求。对于患有早产儿贫血的早产儿，建议临床医生使用最近发表的两项临床试验中的一项限制算法。在极早产儿中，超出这些算法的输血没有循证医学依据，并且受到积极劝阻。
