Objective: To explore the application effect of nursing intervention under feedforward control in the treatment of children with bronchial pneumonia by aerosol inhalation. Methods: A total of 96 hospitalized children with bronchopneumonia treated by aerosol inhalation in pediatrics of Chizhou People’s Hospital from January 1, 2019 to December 31, 2019 were divided into a control group and an observation group according to different nursing methods, 48 cases in each group. The control group received routine nursing, while the observation group received feedforward control nursing on the basis of routine nursing. The compliance, standardization, nursing satisfaction and symptom relief time of aerosol inhalation treatment were compared between the two groups. Results: After intervention, the excellent and good rate of atomization inhalation treatment compliance in the observation group was 91.67%, which was significantly higher than 75.00% in the control group, and the difference was statistically significant (P<0.05). The percentage of normative atomization inhalation action and residual dose <0.33 mL in the observation group were significantly higher than those in the control group, the differences were statistically significant (all P<0.05). The total nursing satisfaction of the observation group was significantly higher than that of the control group (P<0.05). The cough relief time, antipyretic time, and pulmonary rales disappearance time in the observation group were shorter than those in the control group (all P<0.05). Conclusion: Nursing intervention under feedforward control can significantly improve the compliance and standardization of aerosol inhalation therapy in children with bronchial pneumonia, which is beneficial to the recovery of children’s condition and improve nursing satisfaction.
