Efficacy comparison of high-frequency oscillatory ventilation with continuous nasal positive airway pressure in neonatal respiratory distress syndrome treatment.

OBJECTIVES To compare the treatment efficacy of high-frequency oscillatory ventilation (HFOV) with nasal continuous positive airway pressure (NCPAP) in the treatment of neonatal respiratory distress syndrome (NRDS) and its effect on the expression of high-mobility group protein B1 (HMGB1). METHODS A total of 180 infants with NRDS admitted to our hospital were included and randomly assigned into the HFOV group (receiving conventional therapy and HFOV), the NCPAP group (receiving conventional therapy and NCPAP), and the conventional group (receiving conventional therapy). Qi and blood indicators, heart rate, respiratory frequency, PCO2, and PaO2 were observed and recorded before and after treatment, together with complications after treatment. ELISA was performed for HMGB1 Results: A distinctly lower partial pressure of carbon dioxide (PCO2) but higher arterial partial pressure of oxygen (PaO2) was observed in the HFOV and NCPAP groups than in the conventional group (P 0.05). The serum HMGB1 levels in both groups were significantly higher than those in the conventional group (P < 0.05). DISCUSSION Both HFOV and NCPAP are feasible in the treatment of NRDS and may play a role in the inhibition of HMGB1.
