Esophageal Atresia Symptoms, Types & Mnemonics [3 C’s]

Esophageal atresia is something most people have likely never heard of, let alone know the signs and symptoms. This congenital disorder affects 1 in 4,000 newborns annually and can be severe if left untreated. In this blog post, we will go over what esophageal atresia is type c tef, its common symptoms, and a helpful nursing mnemonic known as “The 3 C’s” to remember them easily. Proper understanding and quick diagnosis of esophageal atresia can be effectively managed, leading to better outcomes for these infants ranging from mild discomfort to surgical repair needs.

What is Esophageal Atresia?

Esophageal atresia is a rare but severe birth defect that can cause serious complications for infants. It occurs when the esophagus, the tube that carries food from the mouth to the stomach, does not develop properly. In cases of esophageal atresia, the upper and lower portions of the esophagus are disconnected, making it impossible for ingested food and liquid to reach the stomach. This can result in impaired gas exchange, causing difficulty breathing and potentially leading to pneumonia. While the condition can be daunting, there are treatment options available that can improve outcomes for affected infants.


There are mainly four types of esophageal atresia: Type A, Type B, Type C, and Type D.

  1. Type A is when the upper portion of the esophagus ends in a blind pouch, and there is no connection to the lower part.
  2. Type B is when the two portions of the esophagus are connected but not correctly aligned, resulting in a gap that can lead to food or liquid leaking into the airways.
  3. Type C occurs when there is an opening between the trachea and esophagus, known as a tracheoesophageal fistula (TEF). This type c TEF can cause life-threatening complications such as aspiration pneumonia. TEF type c can cause liquids or food that has been swallowed to be unintentionally inhaled into your child’s lungs. 
  4. Type D occurs when part of the stomach has grown up towards the chest cavity instead of down, leading to obstruction and inability to feed effectively.

Esophageal Atresia Symptoms

The symptoms of esophageal atresia can vary depending on the severity of the condition. Common signs to watch out for include:

  • Excessive drooling or gagging
  • Coughing and choking while eating
  • Inability to swallow solid food, liquids, or saliva
  • Abdominal distention due to the buildup of gas in the stomach
  • Difficulty breathing, shortness of breath, and rapid breathing


If left untreated, esophageal atresia can lead to various serious complications. These include dehydration, poor weight gain, aspiration pneumonia, and even death if not managed correctly. Additionally, in cases where the upper and lower esophageal portions are too far apart, surgical repair is needed as soon as possible.


Esophageal atresia is typically diagnosed during a routine prenatal ultrasound. The doctor may notice that the baby’s esophagus does not appear connected to the stomach or has an abnormal shape. If this occurs, the doctor will recommend additional testing, such as an endoscopy or barium swallow study to confirm a diagnosis and provide further guidance on treatment options.


Treatment for esophageal atresia depends on the type and severity of the disorder. In mild cases, doctors may recommend dietary changes or medications to reduce symptoms such as difficulty swallowing. For more severe cases, however, surgery is typically necessary to reconnect the two portions of the esophagus so that food can adequately pass into the stomach. Sometimes, a gastrostomy tube may be recommended to provide nutrition while waiting for surgery.

Nursing Mnemonic (The 3 C’s)

Due to its rarity, esophageal atresia can be hard to remember and adequately diagnose. To help nurses quickly identify the signs and symptoms of this birth defect, a helpful mnemonic is known as “The 3 C’s”: 

  1. Cyanosis
  2. Choking
  3. Chest Congestion.

Recalling these symptoms quickly can help nurses identify the condition quicker, ultimately leading to better outcomes for the patient. By remembering these three common signs of esophageal atresia, nurses can better assess infants for this disorder and provide timely treatment. 

Final Words

In conclusion, esophageal atresia is a rare but severe birth defect requiring quick diagnosis and treatment to prevent potential complications. Knowing the signs and symptoms of this disorder and using The 3 C’s mnemonic can help nurses better assess and treat affected infants, leading to improved outcomes. With proper management, most cases of esophageal atresia will resolve with minimal to no long-term effects. However, it is essential to be aware of the condition so that early detection can lead to successful treatments.
