If a child exhibits obvious symptoms of a foreign object in the trachea, it can have a significant impact on their health, potentially leading to difficulty breathing and a blue complexion. It is essential to seek immediate medical attention and use X-ray imaging or a standard chest CT scan to determine if there is a foreign object in the trachea. This can prevent severe infections and inflammation. Additionally, multi-slice spiral CT scanning can be an effective method for diagnosis and further assessment. Seek medical treatment promptly to address the tracheal foreign object promptly.
