Sleep Apnoea in Children: Causes and Treatments

上次更新时间: 7 11月 2019 | 4 分钟阅读时间

Sleep apnoea does not only affect adults. Paediatric sleep apnoea is more common than you might think.

What is sleep apnoea?

Sleep apnoea is a breathing disorder that occurs when you are asleep. Apnoea means a pause in breathing. If it is due to a blockage in the nose or throat, it is known as obstructive sleep apnoea. If the brain does not send the correct signals to control your breathing, it is known as central sleep apnoea. Obstructive sleep apnoea is much more common, but both children and adults can experience either.

Sleep apnoea symptoms in kids

If your child has sleep apnoea, you might notice the following:

During sleep:

  • Snoring
  • Frequent awakenings from sleep
  • Restless tossing and turning
  • Breathing only through the mouth
  • Choking and coughing during sleep
  • Noticeable pauses in breathing often with a 'snort'
  • Bed-wetting

During the day:

  • Tiredness
  • Falling asleep in school or napping at unusual times
  • Attention problems or poor performance in school
  • Hyperactivity and other behavioural problems
  • Personality changes such as being moody, cranky or irritable
  • Headaches, especially in the morning, upon waking up

Very young children (under 2 years old) are unlikely to snore, which makes it harder to pinpoint sleep apnoea in this age group.

Effects of paediatric sleep apnoea

Effects of sleep apnoea
Over time, sleep apnoea can have significant effects on your child. Fatigue can lead to poor concentration and the inability to function during the day. This leads to poor school performance. It can also cause hyperactivity and mood swings. Due to reduced oxygen intake through the night, children can experience growth or developmental delays in severe cases. Paediatric sleep apnoea is also associated with heart problems, high blood pressure and childhood obesity, and can have an impact on brain function and intelligence.

Causes of sleep apnoea in children

Swollen or enlarged tonsils and adenoids usually cause obstructive sleep apnoea. The excess tissue can block your child's airway. This prevents regular smooth breathing and results in long pauses between breaths. Obstructive apnoea can also be caused by a lack of muscle tone in children with Down's syndrome, cerebral palsy, or similar conditions, as the throat muscles collapse more easily.

Central sleep apnoea, where your brain does not signal your body to breathe properly, is usually caused by an underlying medical condition. Premature babies are more likely to suffer central sleep apnoea, as well as infants with heart problems, congenital anomalies, or those taking certain medications.

Causes of sleep apnoea in adults

Obstructive sleep apnoea is more common in adults than in children and is worsened by obesity. Excess upper airway tissue and fat and poor muscle tone results in blockage and obstruction of the upper airway during sleep, leading to snoring and sleep apnoea. The shape of your jaw and bone structure can also play a role.

Sleep apnoea also runs in families, so if you suffer from sleep apnoea, your children may be more at risk.

Treating sleep apnoea

Treatment of sleep apnoea
Diagnosing sleep apnoea in children is more difficult than in adults. This is because symptoms are often more subtle in children and they may not be able to explain how they feel. For a proper diagnosis, your doctor will probably recommend you see an ENT specialist. They may order a sleep study to monitor your child overnight.

Sensors will be used to track your child's heart rate, breathing, oxygen and brain activity during sleep. An alternative is at-home oximetry testing, but it may not give a clear diagnosis, and a sleep study might still be required.

It is important to monitor sleep apnoea in children to prevent long-term problems. Your doctor might recommend treatment such as:

  • Nasal steroids to open the airways
  • Surgery to remove tonsils or adenoids
  • Treatment of any underlying conditions
  • A continuous positive airway pressure (CPAP) machine, which keeps the airway open overnight with a continuous flow of air through a mask

The choice of treatment will depend on the type of apnoea your child has. Children can also grow out of sleep apnoea, so your doctor may want to wait before taking any decisive action.

If your child is experiencing sleep apnoea due to their weight, which is usually more common in adults, then your doctor will probably recommend seeing a dietitian and increasing exercise levels to manage this.

If your child has obstructive apnoea due to enlarged tonsils or adenoids, in most cases surgery will cure the apnoea.

What should I do if my child has sleep apnoea?

If your child is experiencing symptoms that suggest sleep apnoea, even if it is just irritability or fatigue and poor sleep, you should see your doctor as soon as possible. You may wish to make a video recording of your child sleeping to show your doctor.

As untreated sleep apnoea can have an impact on the way your child develops and grows, it is vitally important to treat this condition. Your child will also be at risk of developing heart disease, stroke and diabetes as adults if the sleep apnoea is not treated.

If you suspect your child has sleep apnoea, make an appointment for your child to see a doctor or an ENT specialist. Many children have sleep apnoea and their parents are not aware, but it can be easily managed if properly diagnosed.
