Application of non-invasive ventilation in children with airway obstructive diseases / 中华实用儿科临床杂志

ABSTRACT

Objective To investigate the application of non-invasive ventilation in children with airway obstructive diseases,especially those who had obstructive sleep apnea syndrome(OSAS).Methods A case follow-up study was conducted between October 2005 and October 2013 in children who had airway obstruction that led to OSAS or chronic respiratory failure and had been given non-invasive ventilation therapy.Children received non-invasive ventilation support,and pressure titration was performed manually in the sleep center while the mode was chosen according to their disease condition.Pulse rate,oxygen saturation or polysomnography were monitored during the treatment.Some patients went on receiving ventilation support when discharged home depending on their disease status.Patients were followed up every 3,6,or 12 months.Results Thirty-seven patients received non-invasive ventilation treatment till October 2013.Thirty-two cases were boys,and 5 cases were girls.The age ranged from 1 year old and 2 months to 12 years old and 6 months.The underlying diseases included OSAS with adenotonsillar hypertrophy,OSAS with mucopolysaccharidosis,mental retardation,cerebral palsy,morbid obesity,and bronchiolitis obliterans.All the OSAS patients had their snoring and apneas relieved,and respiratory distress and daytime symptoms were improved.Regarding the sleep study parameter,the apnea hypopnea index (P ＜ 0.001),obstructive apnea index (P =0.001),oxygen desaturation index(P =0.001),minimum oxygen saturation (P ＜ 0.001) were improved.Till the end of the study,18children (49％)were still receiving non-invasive ventilation,9 children (24％)stopped ventilation after discharge home,4 children (11％)ceased treatment as their symptoms disappeared and polysomnography data was normal,4 children (11％) lost follow-up 3 months after treatment,and 2 children (5％) died of underlying disease.Conclusions Some children with airway obstruction need non-invasive ventilation support.Non-invasive ventilation therapy can be successfully performed in pediatric population.
