Outline

Case presentation: Cough, Hypoxia, and Down Syndrome

Differential Diagnosis Multi-system complications of patients with

Trisomy 21 Treatment and Monitoring

Chief Complaint

9 month old female with Down Syndrome referred to pulmonary clinic for initial evaluation because of cough and persistent oxygen requirement

Page 4: Western States Pediatric Pulmonary Case Conference Cough, Hypoxia, and Down Syndrome Emily DeBoer, MD The Children’s Hospital University of Colorado September.

History of Present Illness

Daily cough for months - day and night No increased work of breathing Snoring Gags with jejunal feeds

Treated with RanitidineSevere oral aversion, tastes by mouth

Past medical/surgical history Trisomy 21 Born at 36 weeks in Colorado Esophageal atresia without TEF

What should we do?

What should we do?

Differential Diagnosis – cough, hypoxia Reflux / aspiration Pulmonary edema Airway anomaly / poor airway clearance Asthma Interstitial lung disease Pneumonia/infection

What should we do?

Differential Diagnosis – cough, hypoxia Reflux / aspiration Pulmonary edema Airway anomaly / poor airway clearance Asthma Interstitial lung disease Pneumonia/infection

Because of her Down Syndrome, she is at risk for aspiration, heart disease, tracheal anomalies, obstructive sleep apnea, pulmonary hypertension

Pulmonary Hypertension Causes of secondary PAH

Cardiac/Vascular anomaly Chronic lung disease

Trisomy 21 Aspiration / reflux Overcirculation from PDA (repaired at 5 months)

Obstructive sleep apnea Thromboembolic disease Collagen vascular disease Thyroid disease HIV
