Abstract

OBJECTIVE

To determine the predictive value of chest X-ray for the depth of tracheal intubation in infants.

METHODS

Basic data of 161 infants under 3 years old was collected. Tracheal length was measured on preoperative chest radiographs to guide intubation depth. Correlation analysis was performed to examine relationships between tracheal length, age, and body weight.

RESULTS

161 cases (male/female = 142/19, no significant difference in sex, p = 0.09) were included, aged from 1 month to 28 months, weight from 2.5 kg to 18.0 kg. The endotracheal intubation depth reached the standard rate was 100 %, with 0 cases of over-deep or over-shallow intubation. Correlation analysis showed that tracheal length was positively correlated with both age and body weight, with stronger correlations observed in infants aged 1-12 months (r = 0.751 for age, r = 0.672 for weight, p < 0.01) compared to those aged 13-28 months (r = 0.672 for age, r = 0.408 for weight, p < 0.01).

CONCLUSION

Direct measurement of tracheal length on routinely performed chest X-rays is simple, feasible and safe, and may be another choice for guiding the depth of tracheal intubation in children.

摘要

目的

确定胸部 X 光片对婴儿气管插管深度的预测价值。

方法

收集了 161 名 3 岁以下婴儿的基本数据。术前胸部 X 光片测量气管长度，指导插管深度。进行相关性分析，以检查气管长度、年龄和体重之间的关系。

结果

纳入 161 例（男/女=142/19，性别无显著差异，p=0.09），年龄 1 个月至 28 个月，体重 2.5 至 18.0 公斤。气管插管深度达到标准率为 100%，无过深或过浅插管。相关性分析显示，气管长度与年龄和体重均呈正相关，1-12 月龄婴儿相关性更强（年龄 r=0.751，体重 r=0.672，p<0.01），13-28 月龄婴儿相关性较弱（年龄 r=0.672，体重 r=0.408，p<0.01）。
