Abstract: Objective To provide hierarchical chain care joint intervention for children with neonatal pneumonia and explore its application effect. Methods A total of 66 children with neonatal pneumonia treated in the neonatology department of Chifeng Hospital from June 2022 to December 2023 were selected and randomly divided into control group (33 cases, conventional care) and experimental group (33 cases, hierarchical chain nursing combined intervention) by envelope drawing method. T-test was used to compare the time of symptom disappearance, length of hospital stay, physical stress and oxygenation indexes of the two groups, and χ² test was used to compare nursing satisfaction. Results The disappearance time of fever, cough, lung rales, chest X and shadow were shorter than those of the control group (P<0.05); Oxyoxygen saturation (SpO₂), heart rate (HR) and respiration (R) were higher than / lower than the control group (P<0.05), The oxygen partial pressure (PaO₂) and oxygenation index (PaO₂/ FiO₂) were higher than the control group (P<0.05), The difference between alveolar-artery oxygen (A-aDO₂) was lower than that of the control group (P<0.05); The nursing satisfaction of the children was higher than that of the control group (P<0.05). Conclusion The hierarchical chain nursing consortium intervention has important value in neonatal pneumonia, which can accelerate the resolution of pneumonia symptoms in children, and promote the improvement of pulmonary oxygenation function to a certain extent, shorten the length of hospital stay, and improve nursing satisfaction.
