The treatment was mainly oral bronchodilators and intravenous hormones, and inhalation therapy accounted for only 34.4%. Conclusion The prevalence of childhood asthma has increased significantly. Attention should be paid to avoiding factors that induce asthma attacks, and the promotion and popularization of inhalation therapy for asthma should be strengthened
