This study evaluated the efficacy of terbutaline combined with Xiao’er Kechuanling in treating pediatric asthma and its effect on airway remodeling indicators. Eighty children were randomized into control (n = 40, terbutaline) and observation (n = 40, terbutaline + Xiao’er Kechuanling) groups, both receiving routine therapy. Clinical efficacy, adverse reactions, symptom relief time, lung function, and airway remodeling indices were compared. The observation group showed higher efficacy (χ² = 4.909, P = .027), higher FVC, FEV1, and FEV1/FVC (t = 2.161, 6.648, 2.980, all P < .05), shorter relief times for dyspnea, wheezing, and cough (t = 9.402, 3.276, 7.133, 4.481, all P < .05), and lower airway remodeling indices (t = 7.715, 5.829, 3.484, 5.023, all P < .001). Adverse reactions showed no difference (χ² = 0.103, P = .749). Terbutaline plus Xiao’er Kechuanling improved efficacy, lung function, and airway remodeling, accelerated symptom relief, and was well tolerated.
