Effects of Bladder Voiding on Sleep Architecture in Infants

Sleep changes rapidly during the first year of life. Brain maturation is accompanied by sleep consolidation in several episode during day and night (daytime naps and night sleep) and progressive organization during the 24h period (more wake during day et more sleep during night). In the first months of life, sleep episodes are frequently interrupted by wake, possibly induced by multiple external and internal stimuli. One of this stimulus could be bladder voiding that is particularly frequent in babies. Only one team worked on the link between sleep and bladder voiding and reported that bladder voiding was associated with cortical arousal during a daytime nap in a little group of babies.

In this study, investigators propose to study the relationship between sleep and bladder voiding in a bigger group of infant and during daytime but also nighttime sleep.

Treatment and study plan

Study of the effect of bladder voiding on sleep fragmentation during day and night sleep

Other

Vigilance state of babies will be continuously recorded during the first 24 hours of hospitalization by polysomnography and actigraphy. In parallel, bladder voiding episodes will be detected with an innovative device placed on babies diapers.

Primary outcomes

  1. Occurrence of arousals / awakenings in a timely relation with bladder voiding.

    Time frame: 24 hours

    The occurrence of arousals and awakenings will be determined form polysomnography signals including electroencephalogram (EEG), electrooculogram (EOG) and a electromyogram (EMG). Arousals and awakenings will be scored as defined by the international rules for visual scoring of EEG (AASM manual 2007). Investigators will calculate the percentage of bladder voiding episode leading to arousal / awakening events

Secondary outcomes

  1. Sleep stage following bladder voiding events

    Time frame: 24 hours

    Sleep stages will be scored as defined by the international rules (AASM 2007). Investigators will determine the proportion of bladder voiding events leading to a change of sleep stage.

  2. EEG frequencies following bladder voiding episodes

    Time frame: 24 hours

    EEG will be quantitatively analyzed and the power spectrum in each frequency band will be determined. Investigators will determine the proportion of bladder voiding events followed by a significant change of EEG frequencies.

  3. Heart rate following bladder voiding episode

    Time frame: 24 hours

    EKG will be obtained during the entire record. Investigators will determine the proportion of bladder voiding followed by a significant change of heart rate

  4. Activity record with actigraphy in babies

    Time frame: 24 hours

    Coherence analysis between actigraphy and polysomnography records
