新生儿呼吸窘迫综合征(NRDS)是由肺表面活性物质缺乏引起,主要发生在早产儿。临床以进行性呼吸困难为主要表现。肺表面活性物质固尔苏(curosurf)自从投入临床以来,由于可以有效地促进氧合、减少呼吸机的使用、减少气漏、降低病死率等优点,已被广泛应用于治疗NRDS。近年来随着固 Neonatal respiratory distress syndrome (NRDS) is caused by a lack of pulmonary surfactant, mainly in preterm infants. Clinical progressive dyspnea as the main performance. Since its introduction into the clinic, curosurf, a pulmonary surfactant, has been widely used to treat NRDS due to its advantages of oxygenation, reduction of ventilator use, reduction of air leaks and reduction of mortality.
