Infantile apnea is a rare disease that is characterized by cessation of breathing in an infant for at least 20 seconds or a shorter respiratory pause that is associated with a slow heart rate, bluish discolouration of the skin, extreme paleness, gagging, choking and/or decreased muscle tone. Infantile apnea occurs in children under the age of one and it is more common in premature infants. Symptoms of infantile apnea occur most frequently during the rapid eye movement (REM) stage of sleep. The nature and severity of breathing problems in patients can be detected in a sleep study called a polysomnography which measures the brain waves, heartbeat, body movements and breathing of a patient overnight. Infantile apnea can be caused by developmental problems that result in an immature brainstem or it can be caused other medical conditions. As children grow and develop, infantile apnea usually does not persist. Infantile apnea may be related to some cases of sudden infant death syndrome (SIDS) however, the relationship between infantile apnea and SIDS is not known. Cause
√ having a family history of sleep apnea. √ being overweight or obese. ✓ having certain medical conditions (cerebral palsy, Down syndrome, sickle cell disease, abnormalities in the skull or face)
✓ being born with a low birth weight. ✓ having a large tongue. Diagnosis
Classification
There are three major categories of apnea known as central, obstructive, and mixed apnea.
Cases of obstructive apnea are rarely found in infants that are healthy. Mixed Apnea
Mixed apnea is a combination of both central and obstructive factors. The majority of premature infants with sleep apnea have mixed apnea. Epidemiology
When infants have a lower birth weight or younger gestational age, there is a greater risk of infantile apnea. With the advancement of neonatal intensive care units and the greater technology available, there are more successful premature births compared to the past. With the greater number of premature infants being born, there is also a greater number of children with infantile apnea. Approximately 85 percent of infants born with a weight less than 2.2 pounds (1 kg) experience infantile apnea within the first month after birth. This risk decreases to 25 percent for infants weighing less than 5.5 pounds (2.5 kg). Studies have found that almost 2% of the pediatric population experience obstructive sleep apnea. == References ==
