Insights
Telemetry data cannot reliably predict obstructive sleep apnea (OSA) in infants with Pierre Robin Sequence (PRS). Sleep studies remain essential for diagnosing OSA in this high-risk population.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Genetics
Background:
- Pierre Robin Sequence (PRS) is associated with a high incidence of obstructive sleep apnea (OSA).
- Current diagnostic protocols often involve polysomnography (sleep studies).
- Exploring non-invasive predictors like telemetry data could streamline OSA diagnosis.
Purpose of the Study:
- To investigate the correlation between continuous telemetry data and polysomnogram (PSG) findings in infants with PRS.
- To determine if telemetry data can accurately predict the presence and severity of OSA, potentially avoiding the need for sleep studies.
Main Methods:
- Retrospective review of 46 infants with PRS who underwent PSG.
- Comparison of telemetry metrics (oxygen nadir, desaturations) with PSG results (Apnea-Hypopnea Index, oxygen nadir).
- Statistical analysis including correlations, scatterplots, and chi-squared tests.
Main Results:
- No significant correlation was found between most telemetry data points and PSG findings.
- Telemetry oxygen nadir did not reliably predict sleep study oxygen nadir.
- A trend suggested a link between average desaturations and AHI, but it lacked statistical significance.
Conclusions:
- Telemetry data is not a reliable tool for ruling out severe OSA in infants with PRS.
- The study does not support foregoing sleep studies in PRS patients with suspected OSA, even with normal telemetry.
- Polysomnography remains crucial for accurate OSA diagnosis in this population.
Objective:
This study looks to correlate telemetry data gathered on patients with Pierre Robin Sequence (PRS) with sleep study data. Strong correlation might allow obstructive sleep apnea (OSA) to be reasonably predicted without the need for sleep study.
Methods:
Charts from forty-six infants with PRS who presented to our children's hospital between 2005 and 2015 and received a polysomnogram (PSG) prior to surgical intervention were retrospectively reviewed. Correlations and scatterplots were used to compare average daily oxygen nadir, overall oxygen nadir, and average number of daily desaturations from telemetry data with apnea-hypopnea index (AHI) and oxygen nadir on sleep study. Results were also categorized into groups of AHI ≥ or <10 and oxygen nadir ≥ or <80% for chi-squared analysis.
Results:
Our data did not show significant correlations between telemetry data and sleep study data. Patients with O2 nadir below 80% on telemetry were not more likely to have an O2 nadir below 80% on sleep study. Patients with an average O2 nadir below 80% did show some correlation with having an AHI greater than 10 on sleep study but this relationship did not reach significance. Of 22 patients who did not have any desaturations on telemetry below 80%, 16 (73%) had an AHI >10 on sleep study.
Conclusions:
In the workup of infants with PRS, the index of suspicion is high for OSA. In our series, telemetry data was not useful in ruling out severe OSA. Thus our data do not support forgoing sleep study in patients with PRS and concern for OSA despite normal telemetry patterns.
