Abstract

Introduction: Optimal positioning of the endotracheal tube is a crucial step in the airway management of neonates. Short airway length creates a narrow margin of safety and thus a higher chance of ETT malpositioning. Published literature reports airway length of 5-7.5 cm, which is primarily based on autopsy and radiologic studies. We decided to measure the airway length in neonates undergoing surgeries using flexible fiberoptic bronchoscopy (FFOB).

Methodology: Sixty full-term neonates, scheduled for surgery under general anesthesia with endotracheal intubation, were included in the study. Neonates with airway anomalies and anticipated difficult airways were excluded. Airway length was measured using FFOB.

Results: Sixty neonates were included in the study. The mean airway length ± SD was 3.85 ± 0.71 cm. The mean ± SD length in males was 3.87 ± 0.63 cm, and in females was 3.82 ± 0.86 cm. The Spearman rank correlation coefficient of airway length (cm) with age was 0.139, and for weight was 0.130.

Conclusion: Airway length is much smaller in neonates as compared to that reported in the literature. Airway dimensions need reassessment in this population in order to improve safety and effectiveness of neonatal intubation practices.

使用纤维支气管镜测量新生儿气道长度。

简介：气管插管的最佳定位是新生儿气道管理的关键一步。短的气道长度造成狭窄的安全范围，因此ETT错位的可能性更高。已发表的文献报道气道长度为5-7.5 cm，主要基于尸检和放射学研究。我们决定使用柔性纤维支气管镜（FFOB）测量接受手术的新生儿气道长度。方法：60例足月新生儿，计划在全身麻醉下气管插管手术，纳入研究。排除有气道异常和预期气道困难的新生儿。采用FFOB测量气道长度。结果：60例新生儿纳入研究。平均气管长度±SD为3.85±0.71 cm。男性平均±SD长度为3.87±0.63 cm，女性平均±SD长度为3.82±0.86 cm。气道长度（cm）与年龄的Spearman秩相关系数为0.139，与体重的Spearman秩相关系数为0.130。结论：与文献报道相比，新生儿气道长度要小得多。为了提高新生儿插管的安全性和有效性，需要重新评估这一人群的气道尺寸。
