SCAVONE, Cristina et al. Pulse oximetry and polysomnography evaluation of premature with or without bronchopulmonary dysplasia. Rev. bol. ped. [online]. 2014, vol.53, n.1, pp.47-53. ISSN 1024-0675.

Objective: determine the need for supplemental oxygen at different stages of behavior in a population of preterm infants. Patients and methods: this is a prospective, descriptive, and longitudinal study. Consecutive preterm infants met the inclusion criteria: gestational age 32 weeks and/ or birth weight 1,500 g. We studied 105 infants with or without BPD. Oximetries were performed at 36 weeks gestational age. Results: the BPD group had lower gestational age, birth weight, head circumference and the number of check-ups during pregnancy than in the group without BPD. The main findings were saturation drops during sleep and in some cases during feeding. Discussion: the differences in clinical variables between the two groups have been reported in different studies. Although pathological oximetry is more common in patients with BPD, some infants without BPD also showed abnormal findings. Conclusion: the real benefits of measuring oxygen saturation at 36 weeks gestational age are reflected in better management of the supply of supplemental oxygen in preterm infants with and without BPD. Also the stimulation of the oropharynx function leads to improved oxygenation during feeding. Both facts tend to optimize growth and development in these populations.
