Sleep related breathing disorders in children

While over 20% of children snore, it is estimated that only 2% of children have obstructive sleep ap- nea syndrome (OSAHS). In recent years it has chan- ged the classication of sleep-disordered breathing in children, adding a new group among patients with essential snoring and patients with obstructive sleep apnea hypopnea syndrome (OSAHS), which are patients with upper airway resistence syndro- me (UARS) not showing apneas or hypopneas on polysomnography, hence the diculty in diagnosis, but like the others they present changes in school performance and/or physical growth and improve after adenotonsillectomy. This work implies an up- date on sleep related breathing disorders in children and propose a model of informed consent.
