潮气呼吸肺功能在毛细支气管炎患儿中的应用

目的观察毛细支气管炎患儿潮气呼吸肺功能的变化,探讨其临床意义。方法对28例毛细支气管炎患儿急性期、恢复期及14例非心胸疾病患儿(对照组)进行潮气呼吸肺功能检测。结果毛细支气管炎组急性期呼吸频率(RR)增高,吸呼比(TI/TE)、每千克体质量潮气量(TV/kg)、达峰时间比(TPTEF/TE)、达峰容积比(VPTEF/VE)均下降,与恢复期及对照组比较差异有统计学意义。恢复期与正常组比较各指标差异均无统计学意义。所有检测患儿的达峰时间(TPTEF/TE)与达峰容积(VPTEF/VE)呈正相关。结论潮气呼吸肺功能是评价婴幼儿呼吸功能的可靠方法,达峰时间(TPTEF/TE)与达峰容积(VPTEF/VE)是判断毛细支气管炎呼吸道阻塞程度的敏感指标。

Clinical Application of Tidal Breath Pulmonary in Infants with Bronchiolitis

Objective To observe the dynamics of tidal breath pulmonary function in infants with bronchiolitis and to explore the clinical significance. Methods The tidal breath pulmonary function of 28 infants with bronchiolitis during acute phase and during admission phase, and the pulmonary function of 14 infants with non-cardiac diseases were tested. Results During the acute phase of infants with bronchiolitis, the respiratory rate （RR） was significantly higher, TI/TE, TV/kg, TPTEF/TE and VPTEF/VE, were significantly lower as compared with those in admission phase and non-cardiac diseases group. In admission phase, the targets showed no statistically significant difference as compared with non-cardiac diseases group. TPTEF/TE of the infants tested characterized positive correlation to the VPTEF/VE. Conclusion The tidal breath pulmonary function could be used to test pulmonary function of infants. TPTEF/TE and VPTEF/VE are correlation to the severity of bronchiolitis, can evaluate the bronchiolitis airway obstruction.
