Less-invasive surfactant administration (LISA) under continuous positive airway pressure is increasingly used for the treatment of neonatal respiratory distress. Different procedures are described, but data on the optimal catheter insertion depth are sparse.
To generate data for recommending an optimal catheter insertion depth in LISA.
We examined 112 anterior-posterior chest X-rays from intubated infants and determined the carina's vertebral projection, whenever possible. After that, distances between the middle of cervical vertebra 4 (C4) and thoracic vertebra 2 and the middle of C4 to thoracic vertebra 3, respectively, were measured. Results were plotted against infant's weight.
A weight-based chart and recommendations for the optimal intratracheal catheter position in infants with a body weight between 350 and 4000 g were created.
Generated data offer standardisation and may thus help to find a balance between risk of surfactant reflux and unilateral surfactant administration.
持续气道正压通气下的微创表面活性剂给药（LISA）越来越多地用于治疗新生儿呼吸窘迫。虽然描述了不同的程序，但关于最佳导管插入深度的数据很少。
为 LISA 中的推荐最佳导管插入深度生成数据。
我们检查了 112 张插管婴儿的前后胸 X 光片，并尽可能确定隆突的椎体投影。之后，测量了颈椎 4 （C4）和胸椎 2 的中点与 C4 到胸椎 3 的中点之间的距离。结果与婴儿的体重相对应。
创建了一个基于体重的图表和建议，用于体重在 350 到 4000 克之间的婴儿的最佳气管内导管位置。
生成的数据提供了标准化，因此有助于在表面活性剂反流和单侧表面活性剂给药的风险之间找到平衡。
