Insights
Investigating sleep position in infants with cleft palate (CP) is crucial for managing sleep-disordered breathing (SDB). This study found oxygen saturation monitoring feasible, suggesting different sleep positions may impact SDB, warranting further research.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Craniofacial Anomalies
Background:
- Cleft palate (CP) can lead to breathing difficulties and sleep-disordered breathing (SDB) in infants.
- The optimal sleep position for infants with CP to mitigate SDB is currently unknown.
- Sleep position is a modifiable factor that may influence SDB severity.
Purpose of the Study:
- To design a pragmatic study investigating the effect of two routinely advised sleep positions (supine vs. side-lying) in infants with CP on oxygen saturations.
- To assess the feasibility and acceptability of home monitoring of oxygen saturation (SpO2) and end-tidal carbon dioxide (ETCO2) in this population.
- To gather preliminary data to inform a future randomized controlled trial.
Main Methods:
- A multicentered observational cohort study was conducted across four UK cleft centers.
- Infants with isolated CP were recruited and monitored at 1 and 3 months of age.
- Home monitoring included SpO2 and ETCO2, supplemented by qualitative parent interviews.
Main Results:
- Oxygen saturation (SpO2) monitoring was feasible, with sufficient recordings obtained in 24 infants (13 side-lying) at 1 month and 19 infants (10 side-lying) at 3 months.
- End-tidal carbon dioxide (ETCO2) monitoring proved challenging, with limited successful recordings and reported unacceptability by parents.
- Parents emphasized the importance of sleep position management for infants with CP.
Conclusions:
- Domiciliary SpO2 monitoring is feasible in infants with CP within a research setting.
- Preliminary findings suggest potential differences in SpO2 based on sleep position, meriting further investigation.
- A randomized study comparing side-lying and supine sleep positions is recommended to better understand SDB in infants with CP.
Objective:
Cleft palate (CP) can affect breathing, leading to sleep-disordered breathing (SDB). Sleep position can affect SDB, but the optimum sleep position for infants with CP is unknown. We aimed to determine the design of a pragmatic study to investigate the effect of the 2 routinely advised sleep positions in infants with CP on oxygen saturations.
Design:
A multicentered observational cohort.
Setting:
Four UK-based cleft centers, 2 advising supine- and 2 side-lying sleep positions for infants with CP.
Participants:
Infants with isolated CP born July 1, 2015, and December 31, 2016. Of 48 eligible infants, 30 consented (17 side-lying; 13 supine).
Interventions:
Oxygen saturation (SpO2) and end-tidal carbon dioxide (ETCO2) home monitoring at age 1 and 3 months. Qualitative interviews of parents.
Outcome Measures:
Willingness to participate, recruitment, retention, and acceptability/success (>90 minutes recording) of SpO2 and ETCO2 monitoring.
Results:
SpO2 recordings were obtained during 50 sleep sessions on 24 babies (13 side-lying) at 1 month (34 sessions >90 minutes) and 50 sessions on 19 babies (10 side-lying) at 3 months (27 sessions >90 minutes). The ETCO2 monitoring was only achieved in 12 sessions at 1 month and 6 at 3 months; only 1 was >90 minutes long. The ETCO2 monitoring was reported by the majority as unacceptable. Parents consistently reported the topic of sleep position in CP to be of importance.
Conclusions:
This study has demonstrated that it is feasible to perform domiciliary oxygen saturation studies in a research setting and has suggested that there may be a difference in the effects of sleep position that requires further investigation. We propose a study with randomization is indicated, comparing side-lying with supine-lying sleep position, representing an important step toward better understanding of SDB in infants with CP.
