Why the study?

Postoperative changes in heart rate variability indices and their importance remain inconclusive in children with obstructive sleep apnea.

Does adenotonsillectomy improve sleep heart rate variability and sleep quality in children with obstructive sleep apnea?

Overview

Adenotonsillectomy may improve HRV and QoL in pediatric OSA; hypothesis-generating from a single case and needs prospective confirmation.

Structured PICO

Does adenotonsillectomy improve sleep heart rate variability and sleep quality in children with obstructive sleep apnea?

P
Population
76 children with obstructive sleep apnea (OSA)
I
Intervention
Adenotonsillectomy
C
Comparator
Pre-operative baseline
O
Outcome
Changes in heart rate variability (HRV) indices, total OSA-18 questionnaire score, and polysomnographic parameterssurrogate

Adenotonsillectomy improves obstructive sleep apnea severity and sleep quality in children, with improvements in apnea-hypopnea index serially mediated by reductions in OSA-18 score and very low frequency power of heart rate variability.
