Thoracentesis of peanuts, with or without the chocolate coating, known as M & Ms and these should be avoided in that age group. Aspiration is a common event. The aspiration can lead to bronchitis or pneumonia, often with cough and the cough may persist for a long time. Food is one type of foreign body that is aspirated. Only 20% of all objects aspirated are show up directly on chest x-ray, also called radio-opaque, and 40% will have a normal chest x-ray. The remainder of the x-rays, while not showing the foreign body itself, will show other signs of its presence such as pneumonia-like shadows, partial lung collapse or hyper-expansion with air-trapping. Given the information of likely aspiration, the radiologist will be much more likely to look for and find the often subtle signs of aspiration of a foreign body – a combination of suspicion and increased perception.
I suggest that you discuss the above with your daughter’s pediatrician without delay, preferably today. It may be necessary for a pediatric pulmonary specialist to perform a fiberoptic bronchoscopy to identify and remove the object, be it a fragment or an entire M & M.
Good luck.
