摘要 目的探讨白三烯受体拮抗剂改善哮喘患儿肺功能的效果。方法应用脉冲振荡(IOS)肺功能仪分别测定20例哮喘患儿单纯糖皮质激素吸入(常规治疗组)治疗前后和30例哮喘患儿加用孟鲁司特(孟鲁司特组)治疗前后肺功能。另选取20例健康儿童作为对照组,并对其疗效进行比较。结果常规治疗组治疗前、孟鲁司特组治疗前脉冲频率为5、20Hz时的气道黏性阻力(R4、R30)、热振频率(Fres)高于对照组[(1.10±0.26)、(1.10±0.21)kPa/(L·g)比(0.54±0.15)kPa/(L·g);(0.75±010)、(0.70±0.11)kPa/(L·g)比(0.53±0.10)kPa/(L·g);(20.11±194)、(19.99±2.64)Hz比(16.90±1.77)Hz],脉冲频率为5Hz时的气道弹性阻力(X5)低于对照组[(-0.44±0.08)、(-0.42±0.13)kPa/(L·g)比(=0.19±0.10)kPa/(L·g)].差异有统计学意义(P〈0.01),而常规治疗组治疗前与孟鲁司特组治疗前各项指标比较差异无统计学意义(P〉0.05)。常规治疗组治疗前后R5、R20比较差异有统计学意义(P〈0.01).X4、Fres比较差异无统计学意义(P〉0.05)。孟鲁司特组治疗前后比较差异有统计学意义(P〈0.01)。常规治疗组治疗后与孟鲁司特组治疗后备项指标比较差异有统计学意义(P〈0.01或〈0.05)。常规治疗组治疗后各项指标与对照组比较差异仍有统计学意义(P〈0.01).孟鲁司特组治疗后R20、Fres与对照组比较差异无统计学意义(P〉0.05).结论加用孟鲁司特治疗时改善哮喘儿重肺功能的效果较好.对提高患儿生活质量有一定的作用。
