Abstract: Objective To provide references for clinical rational use of medicines by analyzing the utilization of oxygen atomization inhalation for the inpatient in our hospital.Methods From the clinical pharmacy workstation, sift the inpatients who were given with oxygen atomization inhalation, then retrospectively analyze the utilization and evaluate the relevant information.Results The major departments using oxygen atomization inhalation were the respiratory medicine, cardiovascular medicine, general surgery, osteology and cardio-thoracic surgery, the proportions were 15.25%, 11.86, 10.89% and 10.17%. Patients under 10 years old (22.03%) and over 51 years old(29.06%) have higher proportions than the others. The medicines used in the largest amount were dexamethasone sodium phosphate injection, 0.9% sodium chloride injection, budesonide suspension for inhalation, ambroxol hydrochloride injection, chymotrypsin for injection. The single average dose was 20.81mL. The proportions of two medicines combination and three medicines combination were 35.53% and 41.65% respectively. The most commonly used medicine combination was terbutaline sulphate solution for nebulization and budesonide suspension for inhalation.Conclusion The oxygen atomization inhalation for patients is basically rational in our hospital, but unlabeled route of administration, the overdose use of medicine in a single time and the irrationally combined use of different medicines existed. Combine the medication guidance of clinical pharmacists and closely cooperate with clinicians to promote the safe, effective and rational use of the oxygen atomization inhalation.
