Abstract:Objective To evaluate the efficacy and safety of NO inhalation combined with high frequency oscillatory ventilation (HFOV) in the treatment of neonates with respiratory distress syndrome (RDS). Methods Sixty-two children with RDS admitted to our hospital from February 2016 to February 2019 were divided into two groups according to the treatment methods, with thirty children received CMV + NO inhalation as the control group and thirty-two children received HFOV+NO inhalation as study group. The improvement of blood gas status and the occurrence of complications were retrospectively analyzed. Results The treatment time of the study group was longer than that of the control group (P < 0.05); After 4, 12 and 24 hours, PaCO2 and A-A PO2 in the Study Group were lower than those in the control group (P < 0.05); PH, PaO2, OI, and SaO2 were higher than those in the control group (P < 0.05); compared with the control group, the value of OI at 4, 12 and 24 hours after treatment in the study group was lower (P < 0.05); the total incidence of complications in the study group was 15.63%, compared with 10.00% in the control group, but there was no significant difference (P > 0.05). Conclusion NO inhalation combined with high frequency ventilation used in the treatment of children with RDS can effectively improve the blood gas state with few complications and obtain good therapeutic effectiveness and safety.
