摘　　要：目的探讨不同危重程度的小儿重症肺炎恢复期肺通气功能指标和小气道功能相关指标的变化。方法回顾性分析2014年1月至2016年12月92例重症肺炎患儿的临床资料,根据小儿危重病例评分分为非危重组、危重组和极危重组。患儿肺炎治愈后于出院前行肺功能检查,对肺通气功能指标和小气道功能相关指标变化进行比较分析。结果三组患儿肺通气功能比较,非危重组患儿每公斤体质量潮气量(VT/kg)为(7. 72±1. 34) ml/kg,呼吸频率(RR)为(31. 21±4. 09)次/min。危重组患儿VT/kg为(7. 47±1. 20) ml/kg,RR为(33. 08±4. 11)次/min。极危重组患儿VT/kg为(7. 11±1. 05) ml/kg,RR为(34. 13±4. 35)次/min。三组患儿肺通气功能指标比较,差异未见统计学意义(P>0. 05)。三组患儿小气道功能比较,非危重组患儿达到潮气呼气峰流速的时间比吸气时间与呼气时间的总和(TPTEF/TE)为(23. 75±3. 20)%,,达到潮气呼气峰流速的呼气容积比呼气量(VPTEF/VE)为(22. 97±3. 29)%。危重组患儿TPTEF/TE为(21. 08±2. 97)%,VPTEF/VE为(18. 38±2. 29)%。极危重组患儿TPTEF/TE为(17. 08±2. 01)%,VPTEF/VE为(14. 82±2. 11)%。三组比较,差异有统计学意义(P <0. 05)。结论 TPTEF/TE和VPTEF/VE对于小儿重症肺炎的预后有着指导意义,而VT/kg和RR指导意义不大。Objective To investigate the changes of pulmonary ventilation function and small airway function related indexes in children with severe critical pneumonia at different risk.Methods From January 2014 to December 2016,92 children with severe pneumonia were enrolled in this study. The children were divided into three groups according to the PCIS score. The changes of pulmonary ventilation function and small airway function were compared and analyzed after pulmonary function was performed before pneumonia was cured. Results The VT/kg was（ 7. 72 ± 1. 34） ml/kg and the RR was（ 31. 21 ± 4. 09）/min in the nonresponders group. The risk of VT/kg was（ 7. 47 ±1. 20） ml/kg and RR was（ 33. 08 ± 4. 11）/min. The incidence of VT/kg was（ 7. 11 ± 1. 05） ml/kg and RR was（ 34. 13 ± 4. 35） times/min. There was no significant difference in the variance of lung ventilation between the three groups（ P〉0. 05）. Compared with the three groups,the TPTEF/TE was（ 23. 75 ± 3. 20） % and the VPTEF/VE was（ 22. 97 ± 3. 29） %. TPTEF/TE was（ 21. 08 ± 2. 97） % and VPTEF/VE was（ 18. 38 ± 2. 29） %. TPTEF/TE was（ 17. 08 ± 2. 01） % and VPTEF/VE was（ 14. 82 ±2. 11） %. There was significant difference between the three groups（ P〈0. 05）. Conclusions TPTEF/TE and VPTEF/VE have guiding significance for the prognosis of severe pneumonia in children,while VT/kg and RR are of little significance.
