Abstract: Objective To understand the drug composition of respiratory diseases in pediatric emergency department in our hospital and provide reference for clinical rational use of drugs. Methods We collected 17 210 pediatric emergency prescriptions and 50 613 medical orders of our hospital in the first 6 days of each month from August to October in 2017, including 14 424 prescriptions for respiratory diseases and 41 927 medical orders, to analyze the pharmacologic categories, drug dosage forms and different pharmacologic categories of respiratory diseases. Results Among the 41 927 medical orders of the respiratory system, 10 049 (23.97%) were antibacterial agents, 9 347 (22.29%) were Chinese patent medicine, 8 873 (21.16%) were antiviral agents, 31 508 (75.15%) were injections and 10419 (24.85%) were other types of drugs. Conclusion Antibiotics, Chinese patent medicines and antiviral drugs were the main drugs used in the pediatric emergency respiratory system diseases in our hospital, but there was an imbalance in the selection of drug dosage forms, especially antibiotics, antiphlegm, antitussive, antiasthmatic drugs and antipyretic analgesics, in which injections were overused.
