摘　　要：目的分析哮喘儿童缓解期肺功能的相关影响因素。方法在哮喘缓解期检测肺功能提示为限制性通气功能不足的儿童中，选择5-13岁儿童30例作为研究对象（研究组）；同时选择30例正常同龄儿童的肺功能检测结果作为对照（正常组），对2组儿童肺功能有关指标进行分析。结果经肺功能图文解读，研究组中21例（70．00％）患儿在检测过程中呼气时间短，未达到呼气平台，其中5-10岁儿童18例（85．7l％），明显高于3例11-13岁的儿童（14．29％），并有显著性差异（确切概率法，P=0．0083）。呼气时间不足的儿童中，肺功能肺活量、用力肺活量明显低于呼气时间足够长的儿童（t值分别为4．54、2．48，均P〈0．05）。结论呼气时间不足是导致限制性通气功能不足的主要原因，哮喘缓解期儿童小气道功能可存在不同程度损害。Objective To exanalyze the related factors of lung function in asthma remission of children. Methods Thirty children aged 5-13 years in asthma remission with restrictive ventilation function deficiency were selected as objects of study （experimental group ）. Meanwhile, 30 normal same aged children with pulmonary function tests were chosen as controls （normal group）. The related indexes of lung function of two groups were analyzed. Results By reading the lung function, 21 cases （70.00%） in the experimental group were breath pressed for time and did not reach the expiratory platform, of which 18 cases （ 85.71% ） were 5-10 years old, which was obviously more than those aged 11-13 years old （3 cases, 14.29% ）. The difference was significant （ Fisher exact test, P = O. 0083 ）. The index of vital capacity and forced vital capacity were significantly lower in the group with exhale pressed for time than that in the group with sufficient exhale time （t value was 4.54 and 2.48, respectively, both P 〈 0.05）. Conclusion Breath pressed for time plays an important role in restrictive ventilation function, and the small airway function in the remission stage of childhood asthma still has different damage.
