Definition: Breathing difficulties during sleep • 10% of Children snore regularly • 2-4% have obstructive sleep apnea SDB in Children
Sleep disordered breathing (SDB) is characterized by an abnormal respiratory pattern during sleep, and includes snoring, mouth breathing, and pauses in breathing. • SDB encompasses a spectrum of disorders that increase in severity from snoring to obstructive sleep apnea. • Obstructive sleep apnea is diagnosed when SDB is accompanied by an abnormal PSG with obstructive events SDB-Definition
Obesity • Enlarged Tonsils and Adenoids • Down’s Syndrome • Other Craniofacial Disorders (Treacher-Collins) • Neuromuscular Disorders (i.e. Cerebral Palsy) • Sickle Cell Disease SBD: Risk Factors
• Appearance • Weight • Body Mass Index • Body Mass Index percentile for Age Different Criteria than adults How do you determine if a child is Obese
• BMI: indirect measure of body fat ▪ BMI for age: sex and age specific values • BMI % for age: indicates the relative position of the child's BMI number among children of same sex and age: Obese > 95% Indirect measure of excess fat and may need to confirm by measuring skin fold thickness Obesity
Similar idea as for height and weight for age. • Age 4 years 10 months, 40 inches, 50 pounds: • BMI 22.0 (>=97%) • Age 5 years 10 months, 44 inches, 50 pounds: • BMI 18.2 (90-94%) BMI Percentage
Snoring • Daytime fatigue • Hyperactivity • Audible Breathing (The Darth Vader sound) • Restless Sleep Symptoms of Sleep Disordered Breathing
Chronic Mouth Breathing • Gasping (arousals) • Enuresis • Sleep in an odd position • Extended neck • Head over the bed Symptoms of Sleep Disordered Breathing
Growth Retardation • Poor School Performance • Behavioral Problems • Irritability • Decreased Quality of Life • Occasionally ADHD Symptoms of Sleep Disordered BreathingCo-Morbid Conditions-Common
Systemic Hypertension • Pulmonary Hypertension • Right Heart Failure: now rare Symptoms of Sleep Disordered BreathingCo-Morbid Conditions-Uncommon
History and Physical Alone • Adenoidal Facies • Tonsil hypertrophy • Audio or Visual Recording • Evidence of struggling while breathing • Sleep Study • Overnight oxygen recording Diagnosis of SDB/OSA

Study by Marcus et al: A Randomized Trial of Adenotonsillectomy for Childhood Sleep Apnea Downloaded from nejm.org on June 12, 2013. • “Children with obstructive sleep apnea who had a common surgery to remove their adenoids and tonsils showed notable improvements in behavior, quality of life and other symptoms compared to those treated with "watchful waiting" and supportive care. However, there was no difference between both groups in attention and executive functioning, as measured by formal neuropsychological tests.” Does Every Child with SDB Need Surgery?
There were significantly greater improvements in behavioral, quality-of-life, and polysomnographic findings and significantly greater reduction in symptoms in the early-adenotonsillectomy group than in the watchful-waiting group.

If SDB are mild or intermittent, academic performance and behavior is not an issue, the tonsils are small or the child is near puberty (tonsils and adenoid often shrink at puberty), it may be recommended that a child with SDB be watched conservatively and treated only if symptoms worsen. Fact Sheet: Pediatric Sleep Disordered Breathing/Obstructive Sleep Apnea. American Academy of Otolaryngology/Head and Neck Surgery, Inc. Updated 11/15/11 Does Every Child with SDB Need Surgery?
The bottom line: • There is no urgency for surgery in those children with mild symptoms, but their quality of life, and therefore their parents or caregivers, may be adversely affected Does Every Child with SDB Need Surgery?
Clinical Practice Guideline: Diagnosis and Management of Childhood Obstructive Sleep Apnea SyndromeAmerican Academy of PediatricsPediatrics 2002;109;704This guideline specifically excludesinfants younger than 1 year, patients withcentral apnea or hypoventilation syndromes, and patientswith OSAS associated with other medical disorders,including but not limited to Down syndrome,craniofacial anomalies, neuromuscular disease (includingcerebral palsy), chronic lung disease, sicklecell disease, metabolic disease, or laryngomalacia.
1) all children should be screened for snoring; 2) complex high-risk patients should be referred to a specialist; 3) patients with cardiorespiratory failure cannot await elective evaluation; 4) diagnostic evaluation is useful in discriminating between primary snoring and OSAS, the gold standard being polysomnography; Clinical Practice Guideline: Diagnosis and Management of Childhood Obstructive Sleep Apnea SyndromeAmerican Academy of Pediatrics
5) adenotonsillectomy is the first line of treatment for most children, and continuous positive airway pressure is an option for those who are not candidates for surgery or do not respond to surgery; 6) high-risk patients should be monitored as inpatients Postoperatively; 7) patients should be reevaluated postoperatively to determine whether additional treatment is required.
