Is bladder voiding in sleeping preterm infants accompanied by arousals?
Polygraphic recordings were performed in 21 healthy preterm infants (10 female). The infants’ gestational age at birth was 31+/-2.7 weeks and postnatal age at study entry was 26+/-8 days (mean+/-standard deviation). Bladder voiding was recorded by an adapted enuresis detector which was connected to the polygraphic computer unit. Arousals were defined as suggested by the International Paediatric Work Group on Arousals.
