A 6-year-old male came to clinic with rhinitis and coughing with a fever for 2-3 days. The maximum temperature was 101°F. He was not eating as much and was more fatigued. He denied specific pain. His mother was more concerned because he’s “making lots of loud sounds and snoring at night” also. She stated that he always seemed to be a noisy sleeper and his snoring got worse if he had an upper respiratory tract infection. She denied paused breathing but could not further characterize the sounds or snoring. She denied daytime fatigue when he was otherwise well, but was concerned because her husband had recently started to use a breathing machine at night for “his own snoring and stopping breathing.” The past medical history showed a well child who was obese. The family history also showed obesity and lipid abnormalities. The review of systems was otherwise negative.
The pertinent physical exam showed a tired male with normal temperature, respiratory rate of 22/minute, heart rate of 88 beats/minute and a body mass index of 28. HEENT showed clear rhinorrhea, +3 tonsils with a smaller midface/oropharynx without erythema or exudate, and tympanic membranes were normal. His lungs had transmitted upper airway noises but no adventitial breath sounds. The rest of his examination was normal.
The diagnosis of an upper respiratory tract infection was made. After discussing the acute infection, the pediatrician discussed the possibility of obstructive sleep apnea and referred the child to an otolaryngologist. A sleep study was performed showing obstructive sleep apnea and the child underwent tonsillectomy and adenoidectomy with marked improvement in his snoring even during acute illnesses. Life style interventions for obesity were also being worked on by the family.
Obstructive sleep apnea syndrome (OSAS) is defined as a “disorder of breathing during sleep characterized by prolonged partial upper airway obstruction and/or intermittent complete obstruction (obstructive apnea) that disrupts normal ventilation during sleep and normal sleep patterns.” It is different than primary snoring which is snoring without apnea, sleep arousals, or problems with gas exchange.
OSAS symptoms include snoring (often with snorts, gasps or pauses), disturbed sleep (often frequent arousals) and daytime neurobehavioral problems. Sleepiness during the day can occur but is less common in children. Risk factors include black race, obesity, adenotonsillar hypertrophy, craniofacial abnormalities, neuromuscular disorders, or family history of disordered breathing.
OSAS occurs in all ages and is most likely under diagnosed with a 2% prevalence rate. Primary snoring has a prevalence of 3-12%. Problems of untreated OSAS include failure to thrive, cor pulmonale including pulmonary and systemic hypertension, and cognitive and behavioral problems. The gold standard for diagnosis is overnight sleep study (polysomnography).
In addition to lifestyle issues such as avoiding tobacco smoke, air pollutants and allergens and treatment of rhinitis and weight loss strategies in some patients, treatment of OSAS for children usually begins with tonsillectomy and/or adenoidectomy. While this can treat many patients, others still will have OSAS. Noninvasive ventilation such as continuous positive airway pressure (CPAP) may be the next step for some children. CPAP devices use a small turbine to create increased pressure that is delivered to the upper airway by a fitted mask. Additional options include other oral-facial surgeries, orthodontic treatments or dental appliances. Drug treatment with nasal steroids and/or montelukast have also been used.
Indications for non-invasive ventilation including CPAP consist of:
- For neonates, infants and pediatric patients
- Obstructive sleep apnea syndrome
- Muscle fatigue, impending of respiratory muscles
- Ventilator management
- Good respiratory drive but still needing minimal respiratory support
- Lung collapse prevention
- For adults
- Obstructive sleep apnea syndrome
- Chronic obstructive pulmonary disease with exacerbation
- Acute congestive heart failure with pulmonary edema
- Acute lung injury
- Neuromuscular disorders
- Ventilator weaning
Absolute and relative contraindications include unstable cardiopulmonary status or need for continuous or near continuous ventilator treatment, inability to protect the airway including reduced consciousness or excessive secretions, air trapping or air leak diseases, problems with facial structures including trauma, burns, recent surgery or esophageal or gastric surgery, patients who are very anxious or uncooperative.
Questions for Further Discussion
1. What is the difference between CPAP and BiPAP?
2. What are your local resources for sleep studies?
3. What history and physical examination findings are there for OSAS?
