Ontwikkeling van een draagbaar bewakingspunt voor pediatrische obstructieve slaapapneu
Background:
Obstructive sleep apnea (OSA) occurs when the blockage of the airway causes a person to stop breathing involuntarily for 10 seconds or more throughout the night during sleep. Pediatric OSA can be especially concerning and can have long-term effects. Researchers want to see how a monitoring device called near-infrared spectroscopy (NIRS) compares with the traditional techniques used in children s sleep studies.
Objective:
To learn about oxygen levels in the brain and limbs in children with and without sleep apnea using a wearable, point-of-care biosensor.
Eligibility:
Children aged 3-12 who have OSA and plan to receive treatment (OSA group) or who do not have OSA (NORM group).
Design:
Participants will be screened with a review of their medical records. If they have taken part in other NIH studies, that data will be reviewed as well.
Participants in the NORM group will have 1 overnight study visit. Those in the OSA group will have 2 overnight study visits.
Participants will do an overnight sleep study. They will have a physical exam and medical history. They will have a sleep study electroencephalography (EEG). For this, electrodes will be placed on their head. They will wear a gauze cap to keep the electrodes in place. Two NIRS probes made of a soft silicon will be placed on their forehead and arm. They will follow their normal bedtime routine. Their parent will stay overnight.
The OSA group will have a second study visit 2 weeks to 12 months after they start treatment for their sleep apnea. They will repeat the sleep study.

Study Description:
This observational study will assess the sensitivity of near-infrared spectroscopy (NIRS) to hemodynamic events caused by pediatric obstructive sleep apnea (POSA). NIRS can provide a direct examination of brain oxygen saturation that traditional sleep study measurements are not able to capture and may be capable of better explaining health outcomes related to this disease. The purpose of this study is to characterize a wearable, point-of-care NIRS device that measures multiple physiological signals with a focus on cerebral and peripheral oxygenation in children with obstructive sleep apnea and to establish the relationship between traditionally measured parameters during sleep studies (polysomnography) and NIRS technologies. This study will be conducted in collaboration with the Sleep and Neurodevelopment Service at the NIH Clinical Center. Care will not be altered for any patients and this study will be purely observational with no significant risk added to any patient. We hypothesize that changes in NIRS signals of cerebral and peripheral tissue oxygenation due to apnea events will correlate with respiratory flow and oxygen saturation changes measured with PSG.
Objectives:
Primary Objective: Characterize cerebral oxygen saturation and peripheral tissue oxygen saturation during both normal sleep and sleep apnea events in children with respect to traditional polysomnography parameters.
Exploratory Objective 1: Characterize cerebral and peripheral tissue oxygen saturation before and after POSA treatment with respect to traditional polysomnography parameters.
Exploratory Objective 2: Characterize the dynamics of hemoglobin concentrations and tissue oxygenation during different sleep stages.
Exploratory Objective 3: Compare dynamics of cerebral and peripheral tissue oxygen saturation during apneic events in sleep state to a breath hold while subject is awake.
Endpoints:
Primary Endpoint: cerebral oxygen saturation (ScO2), peripheral tissue oxygen saturation (StO2), pulsatile oxygen saturation (SpO2), respiratory flow
Exploratory Endpoint 1: baseline and post-treatment ScO2, StO2, SpO2, AHI, respiratory flow
Exploratory Endpoint 2: baseline and post-treatment delta hemoglobin, delta deoxyhemoglobin, cerebral oxygen saturation
Exploratory Endpoint 3: ScO2, StO2 (during apnea and breath hold)
