Ingestion of plastic foreign bodies?


Hello Dr.
Wang, if a plastic foreign object is accidentally ingested and enters the respiratory tract, what should be done? Multiple chest X-rays have shown normal lung findings.

Dr. Wang Yifen reply Radiology


Hello Ms.
Chang, if the individual who ingested the plastic foreign object has no abnormalities in the structure and function of the neck organs (trachea, esophagus), the ingested plastic will enter the esophagus and subsequently be expelled through the gastrointestinal tract in the feces, without entering the respiratory tract.
If there are concerns regarding the function of the neck organs (trachea, esophagus), it is recommended to seek evaluation from an otolaryngologist or a gastroenterologist.
Wishing you safety and good health.

More Info


Accidental ingestion of plastic objects can be a concerning situation, especially when it involves the airway. If someone has accidentally inhaled a plastic object, it is crucial to act quickly and appropriately to minimize potential complications.
First and foremost, it is important to differentiate between ingestion and aspiration. Ingestion refers to swallowing something that enters the digestive tract, while aspiration involves inhaling an object into the respiratory tract. If the plastic object has entered the airway, it can lead to choking, obstruction, or even aspiration pneumonia if not addressed promptly.

If the individual is experiencing difficulty breathing, coughing, or wheezing, these may be signs that the plastic object is obstructing the airway. In such cases, the Heimlich maneuver (abdominal thrusts) should be performed if the person is conscious and able to cough. If the person becomes unconscious, CPR should be initiated, and emergency medical services should be called immediately.

If the individual is not exhibiting any immediate symptoms of distress and has undergone chest X-rays that show normal lung function, it is possible that the plastic object has passed into the esophagus rather than the airway. In this case, the object may eventually pass through the gastrointestinal tract and be expelled naturally. However, monitoring for any signs of discomfort, pain, or changes in bowel habits is essential.

If there is any suspicion that the plastic object may have caused damage to the airway or if the individual experiences persistent coughing, difficulty swallowing, or chest pain, it is advisable to seek medical attention. An evaluation by an ear, nose, and throat (ENT) specialist or a gastroenterologist may be warranted to assess the situation further and determine if any intervention is necessary.

In summary, the handling of accidental ingestion of plastic objects in the airway involves assessing the severity of the situation, performing appropriate first aid measures if necessary, and seeking medical evaluation if symptoms persist or worsen. It is always better to err on the side of caution when it comes to potential airway obstructions, as timely intervention can prevent serious complications.
Additionally, it is important to educate individuals about the risks associated with small plastic objects, especially around children, to prevent such incidents from occurring in the first place. Regular safety checks in environments where small objects are present can help mitigate these risks.
