新生儿呼吸支持技术,尤其是机械通气的发展,使新生儿严重呼吸道疾病的病死率显著降低。然而,目前广泛使用的经气管插管机械通气与严重的并发症如呼吸机相关性肺炎(VAP)、支气管肺发育不良(BPD)、慢性肺疾病(CLD)等密切相关,从而导致远期预后不良。因而,在部分需要气管插管的新? Neonatal respiratory support technology, especially the development of mechanical ventilation, significantly reduces the mortality rate of neonatal severe respiratory diseases. However, the widely used endotracheal mechanical ventilation is closely related to serious complications such as ventilator-associated pneumonia (VAP), bronchopulmonary dysplasia (BPD) and chronic lung disease (CLD), which lead to long-term prognosis bad. Therefore, in some new tracheal intubation?
