This report describes a new standard technique for the measurement of esophageal pressure (Pes) in mechanically ventilated neonates. A neonatal esophageal balloon was positioned in the distal esophagus and inflated with a volume of air determined by static pressure volume curves. Different waveforms demonstrating cardiac contractions, mechanical inspiration, spontaneous breathing, and myoclonic jerks were observed. Measurements made in the supine position were higher than those made in either the right or left lateral position (p less than 0.005). Pes measurements increased notably with barotrauma (p less than 0.025).
本报告描述了一种用于测量机械通气新生儿食管压力（Pes）的新标准技术。将一个新生儿食管气囊置于食管远端，并用根据静压-容积曲线确定的空气量进行充气。观察到了显示心脏收缩、机械通气、自主呼吸和肌阵挛性抽搐的不同波形。仰卧位测量值高于右侧或左侧卧位测量值（p<0.005）。气压伤时Pes测量值显著增加（p<0.025）。
