一个新的公式可以使用简单的床边测量来预测儿科鼻深度 (ND). 这可以提高鼻抽取精度,减少儿童的假阴性.
科学领域:
- 儿科耳鼻喉科 儿科耳鼻喉科
- 医疗器械 医疗器械 医疗器械
- 解剖学测量 解剖学测量
背景情况:
- 准确的儿科鼻深度 (ND) 对于有效的鼻抽样至关重要.
- 目前的方法缺乏个性化,可能导致假负结果.
研究的目的:
- 开发一个儿科ND的预测公式.
- 为了利用表面解剖学测量量量身定制的擦拭技术.
主要方法:
- 一项前性试点研究,涉及63名接受鼻腔内镜检查的儿童.
- 收集的数据包括性别,年龄,身高,体重,ala-tragus距离和小手指的长度.
- 使用逐步线性回归来得出预测公式.
主要成果:
- 儿科ND随年龄显著变化.
- 公式ND (cm) = 2⁄3 (小指长) + 1⁄3 (ala-tragus距离) + 1 (如果有腺切除术史) + 1显示R2为0.78.
- 估计的平均误差为±0.81厘米.
结论:
- 儿科ND是可预测的,使用床边测量小手指的长度和ala-tragus距离.
- 衍生式为个性化鼻手术提供了一种实用方法.
- 需要进一步验证,以提高盲鼻仪器仪表的准确性.

Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
