     SLEEP RELATED UPPER AIRWAY OBSTRUCTION  (SrUAO)
                                                        Key Points

(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
