【摘要】：目的探讨气管支气管软化(TBM)患儿潮气呼吸肺功能的特征,为TBM患儿的诊断、疗效评估、预后判断提供新的思路。方法选取30例经电子支气管镜诊断为TBM的患儿作为研究组,30例健康儿童作为正常对照组。正常对照组和TBM组初诊时以及确诊后3个月、6个月、9个月、12个月进行潮气呼吸肺功能测定。结果 TBM确诊时与对照组在潮气量及吸气时间、呼气时间、吸呼比的差异无统计学意义(P0.05);与对照组比,TBM组确诊时的呼吸频率较快,达峰时间比和达峰容积比较低,差异具有统计学意义(P0.01);TBM患儿初诊时及确诊后3、6、9、12个月的潮气呼吸肺功能达峰时间比、达峰容积比逐渐增大。结论 TBM患儿潮气呼吸肺功能具有特征性改变,而且随着年龄增大,潮气呼吸肺功能逐渐接近正常。
[Abstract]:Objective to investigate the characteristics of tidal breathing and lung function in children with tracheobronchial malacia (TBM), and to provide a new idea for the diagnosis, evaluation of curative effect and prognosis of TBM. Methods 30 children with TBM diagnosed by electron bronchoscopy were selected as study group and 30 healthy children as control group. The pulmonary function of tidal breath was measured at the first visit and 3 months, 6 months, 9 months and 12 months after diagnosis in the normal control group and TBM group. Results there was no significant difference between TBM and the control group in tidal volume, inspiratory time, expiratory time, breath suction ratio (P0.05), and the respiratory rate was faster and the peak time was lower than that in the control group (P0.05). The difference was statistically significant (P0.01) in children with TBM. The peak time ratio and peak volume ratio of tidal respiration and lung function increased gradually at the first diagnosis and 3 months after diagnosis. Conclusion the pulmonary function of tidal breathing in children with TBM has a characteristic change, and with age, the function of tidal breathing lung is approaching to normal gradually.
