Breathing disorders during sleep in premature infants with broncopulmonary dysplasia and pulmonary hypertension
Infants with severe and moderate bronchopulmonary dysplasia (BPD) are characterized by long-term persistence of apnea of prematurity, mainly central genesis, and more significant decrease of ЅрО2. The aim of our study was to assess the character and severity of breathing disorders during sleep in infants the first year of life, born prematurely and having BPD complicated by PH. Were examined 40 infants who were born at 23-31 weeks of gestation, weight at birth less than 1700 g. 31 infants had BPD (mild form was diagnosed in 9 infants, moderate form – in 12 infants and severe form – in 10 infants), 11 infants had BPD complicated by PH. Patients were divided into 3 groups. The first group was made up of the infants without BPD. The second group includes infants with BPD, and 3 group was made up of the infants with BPD complicated by PH. Cardiorespiratory monitoring was performed immediately before discharge from hospital (35-43 weeks post-menstrual age) (infants had not been routine monitored for at list 5 days and had not been received oxygen for at list 8 days). We used “The brief screening questionnaire for infants with sleep problems”, developed by A. Sadeh (author's permission to use the questionnaires was received), as the screening of disorders of sleep in infants. The result was obtained the comparative characteristics of cardiorespiratory indices in the groups of infants and evaluated the character and severity of breathing disorders during sleep, made testing applications screening questionnaire.
