When the normal cardiopulmonary transition fails to occur, the result is persistent pulmonary hypertension of the newborn. Severe persistent pulmonary hypertension of the newborn is estimated to occur in 2 per 1000 live-born term infants, and some degree of pulmonary hypertension complicates the course of >10% of all neonates with respiratory failure. This review article discusses the vascular abnormalities that are associated with neonatal pulmonary hypertension, including recognition of its role in severe bronchopulmonary dysplasia in preterm infants. A systematic review of the evidence for common therapies including inhaled nitric oxide, high-frequency ventilation, surfactant, and extracorporeal life support is included. Finally, this field is rapidly evolving, and the rationale for promising new treatment approaches is reviewed, including inhibition of phosphodiesterases and scavengers of reactive oxygen species.
当正常的心肺过渡未能发生时,结果就是新生儿持续性肺动脉高压。据估计,严重的新生儿持续性肺动脉高压每 1000 例足月产活婴中就有 2 例,而>10%患有呼吸衰竭的所有新生儿的病程中都有某种程度的肺动脉高压。本文讨论了与新生儿肺动脉高压相关的血管异常,包括其在早产儿严重支气管肺发育不良中的作用。对包括吸入一氧化氮、高频通气、表面活性剂和体外生命支持在内的常见疗法的证据进行了系统评价。最后,该领域正在迅速发展,本文还回顾了有前途的新治疗方法的基本原理,包括磷酸二酯酶抑制剂和活性氧清除剂。
