研究目的:

开展高频振荡通气(HFOV)与常频机械通气(CMV)【目前最常用的是同步间歇指令通气加容量保证(SIMV+VG)】治疗新生儿急性呼吸窘迫综合征(NARDS)的随机对照研究,以期了解两种通气模式的利弊,进一步明确NARDS患儿的最佳通气模式及参数设置。  

Objectives of Study:

To conduct a randomized controlled trial of high-frequency oscillatory ventilation (HFOV) versus conventional mechanical ventilation (CMV) [with synchronized intermittent mandatory ventilation plus volume guarantee (SIMV+VG) being the most commonly used mode at present] in the treatment of neonatal acute respiratory distress syndrome (NARDS), in order to understand the advantages and disadvantages of the two ventilation modes and further define the optimal ventilation mode and parameter settings for infants with NARDS.
