TO WHAT EXTENT DO INFANTS PRESENT CENTRAL OR OBSTRUCTIVES APNEAS EVENTS DURING SLEEP?

Introdução

INTRODUCTION: Obstructive apneas are the most frequent respiratory disturbance in prE-pubertal children during sleep. In infants, it is thought that, because of the immaturity of the central respiratory center, central apneas are prevalent.

Objetivo

OBJECTIVES: Evaluate and classify respiratory events and the presence of immaturity of the respiratory patterns using polysomnographic daytime studies.

Métodos

METHODOLOGY: Between January 2010 and March 2013 we undertook Polysomnographic daytime studies (of infants up to one year old) at the Instituto do Sono in São Paulo City.

Resultados

RESULTS: The sample derived from sleep evaluations of 60 infants, 36 males, with 4.3 ± 2.9 months age (16 days to 11 months). Corrected gestational age was 58.3 ± 14 weeks (36 to 87 weeks). Total sleep time was 103 ± 32 minutes. Obstructive apnea index was 11.1 ± 16.1 (0 to 62 events). Central apnea index was 13 ± 18 (0 to 92 events). Twenty-three (23) infants had predominantly central events, 32 obstructive events and 5 presented no abnormal index of respiratory events. Periodic breathing occurred during 3.1 ± 7.2 % of the total sleep time. We noticed that 8 infants spend more than 5% of the total sleep time with periodic breathing and between these, 5 had a corrected conception age greater than 42 weeks.

Conclusões

CONCLUSION: Polysomnographic daytime studies are a robust method to identify sleep respiratory disturbances and breathing immaturity in infants.
