摘要

导言 食管 pH 阻抗监测是诊断儿童胃食管反流的一种工具。pH 导管的位置对于获得可靠的读数至关重要,而目前计算导管插入长度的公式并不完全准确。本研究的目的是为适当插入 pH 值导管制定一个新的计算公式。材料和方法对接受 pH 值阻抗监测的儿童进行了横断面研究,随后进行了放射学检查,以计算正确的导管插入长度。记录的变量包括年龄、性别、体重、身高、窦至窦的距离、窦至胸骨切迹的距离、胸骨切迹至剑突的距离以及根据 Strobel 和身高间隔公式确定的初始插入长度。为预测最终插入长度,进行了多变量回归分析。结果进行了 45 项 pH 阻抗研究,其中 53% 为男性。年龄和体重变量不呈正态分布。在初始回归模型中,与最终插入长度无显著相关性的变量有:性别(P 0.124)、根据 Strobel 或身高间隔公式确定的长度(P 0.078)、窦至窦的距离(P 0.905)和窦至胸骨切迹的距离(P 0.404)。最终公式为5.6 + (身高 cm * 0.12) + (胸骨切迹到剑突的距离 * 0.57) 得出的 R2 为 0.93 (P 0.000)。

Propuesta de una nueva fórmula para la colocación de sondas de pH-impedancia en pacientes pediátricos

Introduction

Esophageal pH-impedance monitoring is a tool for diagnosing gastroesophageal reflux in children. The position of the pH catheter is essential for a reliable reading and the current formulas for calculating catheter insertion length are not completely accurate. The aim of the present study was to develop a new formula for adequate insertion of the pH catheter.

Material and methods

A cross-sectional study was conducted on children that underwent pH-impedance monitoring and later radiographic control, to calculate the correct catheter insertion length. The documented variables were age, sex, weight, height, naris to tragus distance, tragus to sternal notch distance, sternal notch to xiphoid process distance, and initial insertion length determined by the Strobel and height interval formulas. A multivariate regression analysis was carried out to predict the final insertion length. Regression ANOVA and Pearson's adjusted R-squared tests were performed.

Results

Forty-five pH-impedance studies were carried out, 53% of which were in males. The age and weight variables were not normally distributed. In the initial regression model, the variables that did not significantly correlate with the final insertion length were: sex (P 0.124), length determined by the Strobel or height interval formulas (P 0.078), naris to tragus distance (P 0.905), and tragus to sternal notch distance (P 0.404). The final equation: 5.6 + (height in cm * 0.12) + (sternal notch to xiphoid process distance * 0.57) produced an R2 of 0.93 (P 0.000).

Conclusions

This formula can be considered a valid option for placement of the pH-impedance monitoring catheter in pediatrics.
