新生儿持续肺动脉高压的诊治进展 新生儿持续肺动脉高压是一种由多种因素所导致的临床综合征,是新生儿期死亡的主要原因之一,多见于足月儿或过期产儿。临床研究证实,病因及病理类型的差异会影响相同的临床治疗反应。目前临床治疗措施包括药物治疗降低肺动脉压力、机械通气、一氧化氮吸入等,这些新的治疗方法均逐渐成为安全有效的治疗手段。本文就新生儿持续肺动脉高压临床诊治的研究进展进行综述。 [Abstract] The neonatal persistent pulmonary hypertension(NPPH) is the severe disease of neonate and happened in infants or post-term infant,which is caused by many clinical factors and is the main cause of neonatal death.The clinical researches are confirmed that the variation of etiological factors and pathological types can inflect the effect of the same clinical curative.The current clinical therapy methods are included drug therapy to reduce the pulmonary arterial pressure ,mechanical ventilation,inhaling nitric oxide.The new therapy will become the safe and efficient therapy methods.We will take a review to the progress of diagnosis and therapy on neonatal persistent pulmonary hypertension. [Key words] Neonate; Persistent pulmonary hypertension; Clinical therapy 新生儿持续肺动脉高压(persistent pulmonary hypertension of the newborn,PPHN)是影响新生儿健康的一种综合征,多见于足月儿或过期产儿,近年来发病率呈上升趋势,据统计发病率在新生儿中约0.2%[1]。PPHN 又称为持续胎儿循环,是指新生儿出生后因为多种病因导致的肺循环阻力持续性增高,肺循环动脉压超过体循环动脉压,使胎儿型循环过渡至正常成人型循环过程发生障碍,从而致使循环血液经由卵圆孔和动脉导管由右向左分流,导致静脉血进入体循环引起的低氧血症,同时流经肺循环的血液减少,临床出现严重低氧血症等症状[2-3]。目前对PPHN 的诊断及治疗主要依据全国新生儿学组制订的PPHN 诊治常规(2003 年),但是临床对于PPHN 的诊断及治疗仍然较为薄弱。为进一步对PPHN的诊治进行掌握,现对其发病机制及诊治进展进行综述。 1 PPHN 的发病机制 PPHN 并非是单一病因的...
