Abstract:
Objective To explore the application value of high-flow nasal oxygen therapy combined with non-invasive positive pressure ventilation in very low birth weight infants after weaning from invasive mechanical ventilation.Methods From February 2022 to May 2024,80 cases of very low birth weight infants who were weaned from invasive mechanical ventilation in Second Affiliated Hospital of Wenzhou Medical University were selected and divided into single ventilation group and combined oxygen therapy group according to the random number table method,with 40 cases in each group.Single ventilation group was intervened with non-invasive positive pressure ventilation,while combined oxygen therapy group was intervened with high-flow nasal oxygen therapy combined with non-invasive positive pressure ventilation.The disappearance time of clinical symptoms,the score of neonatal behavioral neurological assessment(NBNA),vitamin D and blood gas indicators of two groups of premature infants were compared.And the degree of broncho pulmonary dysplasia(BPD)in premature infants was evaluated.Results The disappearance time of clinical symptoms,non-invasive positive pressure ventilation time and total oxygen requirement time of preterm infants in combined oxygen therapy group were significantly shorter than those in single ventilation group(P＜0.05).After 14 days of intervention,the NBNA scores,vitamin D,oxygenation index and blood oxygen saturation of premature infants in both groups were significantly higher than those before intervention in this group(P＜0.05).The NBNA score,vitamin D,oxygenation index and blood oxygen saturation of preterm infants in combined oxygen therapy group were significantly higher than those in single ventilation group(P＜0.05).The degree of BPD in combined oxygen therapy group was significantly milder than that in single ventilation group(x2=8.571,P=0.003).Conclusion After weaning from invasive mechanical ventilation in very low birth weight infants,high-flow nasal oxygen therapy combined with non-invasive positive pressure ventilation intervention can help reduce inflammatory responses and brain damage,improve blood gas indicators,and lower the degree of BPD.
