摘要
目的探讨潮气呼吸肺功能相关参数测定的临床意义及其在喘息性支气管肺炎婴幼儿呼吸生理评估中的应用价值。方法对本院儿科2013年11月至2014年11月收治的89例处于喘息性支气管肺炎急性期的住院患儿及经治疗后处于缓解期的患儿(观察组)分别进行潮气呼吸肺功能测定,并与同期70例健康婴幼儿(对照组)进行比较,观察两组婴幼儿肺功能指标的变化。结果 1观察组患儿呼吸频率(RR)高于对照组(P<0.05),每千克体重潮气量(TV/kg)、达峰时间比(TPTEF/TE)、达峰容积比(VPTEF/VE)、25%潮气量时呼气流速(TEF25%)、50%潮气量时呼气流速(TEF50%)低于对照组(P<0.05);潮气呼气峰流速(PTEF)、75%潮气量时呼气流速(TEF75%)高于对照组,但差异无显著性(P>0.05)。2观察组患儿急性期RR高于缓解期(P<0.05),吸呼比(TI/TE)、TV/kg、TPTEF/TE、VPTEF/VE、TEF25%、TEF50%均低于缓解期(P<0.05);PEF、TEF75%高于缓解期,但差异无显著性(P>0.05)。3观察组患儿缓解期TI/TE、TPTEF/TE、VPTEF/VE、TEF25%、TEF50%低于对照组(P<0.05),其余指标比较差异无显著性(P>0.05)。结论潮气呼吸肺功能测定在婴幼儿喘息性支气管肺炎病情跟踪观察中具有重要的参考价值,值得推广应用。
Objective To investigate the clinical significance of tidal breathing pulmonary function detection and to assess the application value in the infants with asthmatic bronchopneumonia for the aspects of respiratory physiology evaluation. Method 89 infants in hospitalized with acute asthmatic bronchopneumonia and after treatment in remission（observation group） in our hospital from November 2013 to November 2014 received tidal breathing pulmonary function test, and 70 cases of healthy infants（control group） were compared, and analyzed the changes of pulmonary function index between the two groups. Result 1 Respiratory rate（RR） of infants in observation group was higher than control group, the tidal volume per kilogram of body weight（TV/kg）, peak time ratio（TPTEF/TE）, peak volume ratio（VPTEF/VE）, 25% tidal volume during expiratory flow（PTEF25%）, 50% tidal volume during expiratory flow（TEF50%） of infants in observation group were lower than control group（P〈0.05）, peak tidal expiratory flow（PTEF）, 75% tidal volume during expiratory flow（TEF75%） were higher than control group, the difference was not statistically significant（P〉0.05）. 2 RR of infants in observation group in acute stage was higher than remission stage（P〈0.05）, the inspiratory-respiratory ratio（TI/TE）, TV/kg, TPTEF/TE, VPTEF/VE, TEF25%, TEF50% were lower than remission stage（P〈0.05）, PEF, TEF75% were higher than remission stage, the difference were not statistically significant（P〉0.05）. 3 TI/TE, TPTEF/TE, VPTEF/VE, TEF25%, TEF50% of infants in observation group in remission stage were lower than control group（P〈0.05）, no statistically significant differences in the other indexes（P〉0.05）. Conclusion Tidal breathing pulmonary function detection in the infants with asthmatic bronchopneumoni plays a important role for the predominate reference value, which deserves further clinical applications.
