The use of 6-minute walking experiment in adolescent children with scoliosis and pulmonary insufficiency
6 分钟步行实验法在青少年脊椎侧弯肺功能不全患儿中的使用

摘要

目的 探究 6 分钟步行实验法在青少年脊椎侧弯肺功能不全患儿中的使用价值。方法 选取我 院在 2019 年 3 月~2022 年 2 月收治的青少年脊椎侧弯患儿 60 例作为研究对象，其中 30 例肺功能正常患儿 纳入对照组，30例肺功能不全患儿纳入研究组。收集患儿临床资料，包括 Cobb 角、肺功能检测指标[用力 肺活量（FCV）、第 1 秒用力呼气量（FEV1）、最大呼气流量（PEF）]动脉血气分析指标[氧分压（PaO2）、 二氧化碳分压（PaCO2）]与 6 分钟步行距离。分析 6分钟步行距离与 Cobb角、肺功能检测指标、动脉血气 分析指标的相关性。结果 研究组的 6 分钟步行距离显著短于对照组，FCV、FEV1、PEF、PaO2低于对照组， Cobb角、PaCO2高于对照组（P＜0.05）。经相关性分析得到，6 分钟步行距离与 FCV、FEV1、PEF、PaO2呈 正相关，与 Cobb角、PaCO2呈负相关（P＜0.05）。结论 6分钟步行试验法用于青少年脊柱侧弯中，能够有 效区分伴有肺功能不全的患儿，并且该试验结果与肺功能存在明显相关性，对青少年脊椎侧弯患儿的肺功 能诊断具有重要价值。

Abstract

Objective To explore the value of the 6-minute walk test method in adolescent children with scoliosis and pulmonary insufficiency.
Methods A total of 60 adolescent children with scoliosis who were admitted to our hospital from March 2019 to February 2022 were selected as the research subjects. Among them, 30 children with normal pulmonary function were included in the control group, and 30 children with pulmonary insufficiency were included in the research group . The clinical data of the children were collected, including Cobb angle, pulmonary function test indicators [forced vital capacity (FCV), forced expiratory volume in 1 second (FEV1), maximum expiratory flow (PEF)] and arterial blood gas analysis indicators [partial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2)], and 6-minute walking distance. The correlation between 6-minute walking distance and Cobb angle, pulmonary function test indexes and arterial blood gas analysis indexes was analyzed.
Results The 6-minute walking distance in the study group was significantly shorter than that in the control group, the FCV, FEV1, PEF, and PaO2 were lower than those in the control group, and the Cobb angle and PaCO2 were higher than those in the control group (P<0.05). The correlation analysis showed that the 6-minute walking distance was positively correlated with FCV, FEV1, PEF, and PaO2 , and negatively correlated with Cobb's angle and PaCO2 (P<0.05).
Conclusion   The 6-minute walk test method is used in adolescent scoliosis, which can effectively distinguish children with pulmonary insufficiency, and the test results are significantly correlated with pulmonary function, which is useful for the diagnosis of pulmonary function in adolescent children with scoliosis. important value.
