Abstract

To investigate the feasibility and effectiveness of targeted lung recruitment and the titration of optimal positive end-expiratory pressure (PEEP) in neonates under the guidance of lung ultrasound. The atelectasis neonates from June 2022 to June 2024 in the Neonatology Department of People's Hospital of Pidu were collected and randomly divided into a lung ultrasound scoring (LUS) group and an oxygen (OXY) group, both of which were given mechanical ventilation treatment. The lung recruitment and optimal PEEP were performed by the LUS and OXY methods, respectively. The optimal PEEP and the respiratory and hemodynamic indexes of the two groups were compared before and after lung recruitment and after the optimal PEEP was titrated. After the intervention, the dynamic lung compliance (Cdyn) in the LUS group increased by 38.2% compared with the baseline (from 30.6 ± 4.3 to 42.3 ± 5.1 mL/cmH2O), which was significantly higher than the 21.4% increase in the OXY group (from 29.8 ± 4.1 to 35.6 ± 4.8 mL/cmH2O). The improvement in PaO2/FiO2 in the LUS group was 22.5% higher than in the OXY group. There was no statistically significant difference in the incidence of complications between the two groups. Lung ultrasound can guide neonatal lung recruitment and optimal PEEP titration, improving lung compliance and oxygenation without affecting the safety of treatment.
