Respiratory pauses and apnea during nocturnal sleep in mentally retarded infants
Insights
This study found that respiratory pauses, apnea, and periodic respiration are common in infants with intellectual disabilities during sleep. These breathing irregularities highlight potential respiratory challenges in this population.
Area of Science:
- Pediatric Sleep Medicine
- Neurodevelopmental Disorders
- Respiratory Physiology
Background:
- Infants with intellectual disabilities may exhibit atypical physiological patterns.
- Sleep disturbances and respiratory irregularities are potential concerns in neurodevelopmental disorders.
Purpose of the Study:
- To investigate the prevalence and characteristics of respiratory pauses, apnea, and periodic respiration during nocturnal sleep in infants with intellectual disabilities.
Main Methods:
- Nocturnal sleep recordings were conducted on 42 infants (9-50 weeks post-term) with intellectual disabilities.
- Respiratory events including respiratory pauses (ResP), apnea (Ap), and periodic respiration (PerR) were systematically analyzed.
Main Results:
- All infants exhibited respiratory pauses, with a mean rate of 13.5 per hour.
- Apnea occurred in 22 subjects (mean 4.1 events), with 4 infants experiencing events longer than 15 seconds.
- Periodic respiration was observed in 30 subjects (mean 9.6 events).
Conclusions:
- Respiratory pauses, apnea, and periodic respiration are frequent findings in infants with intellectual disabilities during sleep.
- These respiratory irregularities suggest a need for further investigation into their clinical significance and potential management strategies.
- Sleep-related breathing disorders may be more prevalent in infants with neurodevelopmental impairments.
Abstract:
Respiratory pauses (ResP), apnea (Ap) and periodic respiration (PerR) observed in 42 mentally retarded infants (from 9 to 50 weeks of age post term) were studied throughout nocturnal sleep. All subjects had ResP in the recordings. The range of ResP rates was 4.1-42.1/h, and the mean was 13.5/h. Ap occurred in 22 out of 42 subjects. The range of Ap occurrence (10-15 sec duration) among subjects was 1-10, with a mean of 4.1. Moreover, in 4 out of 22 subjects, Aps of greater than 15 sec duration were seen. In 30 out of 42 subjects, PerR occurred. The range of occurrence of PerR among subjects was 1-35, and the mean was 9.6.
