Sleep apneas in children

Abstract

There are many causes leading to breathing disorders in children. In the newborn period the immature central regulation of breathing can result in a pattern with apneas and bradycardias most commonly seen in the very premature infant. Therefore, during hospital stay many of these very tiny preterms and some of the very ill term infants do have severe apneas and do need medication and or mechanical support (nasal CPAP, positive pressure ventilation). In the first two to three months of life central dysmaturity can persist in some infants and apneas of infancy can occur further on. Infants with prolonged apneas and symptoms like paleness, cyanosis, stiffness or limpness are often investigated, treated or monitored. At the age of two to six, every tenth child is a loud snorer. Every fifth snorer at this age suffers from a severe upper airway obstruction. Factors that decrease pharyngeal size or increase pharyngeal compliance may lead to obstruction. Adenotonsillar hypertrophy is the most common associated condition, craniofacial disorders, central nervous system and neuromuscular problems and less obesity are disposing factors. Children may present nocturnal symptoms like snoring, difficult breathing or disturbed sleep, but most of them have daytime problems as initial complaint such as hyperactivity, behavioral problems, growth failure, poor school performance. Excessive daytime sleepiness is not so common in young children. The childhood obstructive sleep apnea syndrome is a common and serious problem. Children with symptoms suggesting severe obstruction should be evaluated and treated. Most children are cured by adenotonsillectomy whilst some require further therapy.
