Do wet diapers induce arousals in sleeping infants?
OBJECTIVE
To find out whether simulated bladder voiding was able to induce arousals in sleeping infants.


METHODS
Polygraphic recordings were performed in 34 infants and voiding was simulated by administering water into the diaper.


RESULTS
Heart rate, respiratory frequency and electroencephalogram frequency did not change significantly during this procedure. Furthermore, simulated voiding was unable to cause an awakening or to induce body movements in sleeping infants.


CONCLUSIONS
Simulated voiding was unable to induce arousals.
