This page is also available as a PDF.
(based on conference paper by Dr Martin Samuels at RSM conference April
2001)
- Occurs in up to 60% of those with Down's syndrome
- Other disorders of breathing also found. 65-80% of children with
DS have nocturnal hypoventilation and/or decreased oxygen saturation
- Most frequent clinical signs - snoring and chest wall recession.
May also have abnormal sleep postures and frequent nocturnal arousals.
- Restless sleep features in many children both with and without Down's
syndrome and with and without SrUAO
- May be adverse effects on daytime functioning, growth and development.
- Clinic protocols should include specific enquiry re symptoms of SrUAO
on an annual basis.
- Assessment by observation of sleep (eg using video) and sleep studies
as in other children/adults.
- Sleep study facilities/procedures fragmented and variable throughout
UK. May need referral to specialist centre
- May exacerbate pulmonary hypertension in those with congenital heart
disease.
- May lead to life threatening acute obstructive events particularly
if given sedation for any reason.
- Treatment depends on the individual's clinical problem, but Ts and
As may often help. Hospital admission recommended because of increased
risk of post surgery airway problems
- Young children may improve with age
