Question

You are watching your niece who is almost a year old and notice that she is unconscious on the floor with marbles around her. Breaths don’t go in.

Answer 1

The most probable reason for the unconsciousness of the child will be aspiration of the marble particle through the nostrils. that result in teh blockade of the respiratory tract and child doesnt get enough oxygen supply to the brain.

Foreign body aspiration is when an object is inhaled and becomes lodged in a child’s airway or lungs.

Testing and diagnosis

The diagnosis of an aspirated foreign body is based on a combination of the history of the child's illness, the child's presenting symptoms, and chest X-rays. If a foreign body in the airway is strongly suspected, a child needs to go to the operating room and have an airway examination performed under anesthesia. This examination is called a microlaryngoscopy and bronchoscopy (a look at the voice box and windpipe, or airway).

Various size bronchoscopes used to remove a foreign body A child may be diagnosed with foreign body in the airway when a family member has seen the child swallow food or a small object then noticed signs of airway distress, like coughing or difficulty breathing. Children with a persistent segmental pneumonia, especially right lower lobe, should also be considered for foreign body aspiration.

There are three primary ways to see if a child has inhaled something into the airway or lungs:

• Chest X-ray. Some non-food items can be seen in the airway or lungs using a traditional X-ray. However, most food, vegetable matter and plastic toys won't appear on chest X-ray films.
• Inspiratory and expiratory phase X-ray. These are X-rays taken when the child has inhaled and then exhaled the air out of their lungs. If a foreign body cannot be seen with a traditional X-ray, then inspiratory and expiratory phase films may show hyperinflation or air-trapping which suggests an aspirated foreign body.
• Bronchoscopy. When suspicion of aspiration is high enough but the physical exam and X-rays are not definitive for a diagnosis, an instrument called a bronchoscope is inserted through the mouth and used to look at the inside of the airways under anesthesia. Bronchoscopy can be used both to locate the foreign body and to remove it

Treatment

Bronchoscopy is the standard method for removal of an aspirated foreign body. An anesthesiologist puts the child into a deep sleep and then topical lidocaine spray is used to further anesthetize the child's larynx. An instrument called a laryngoscope is inserted into the airway to view the larynx; then a rigid, ventilating bronchoscope is passed beyond it, into the airway, and used to examine the trachea and right and left bronchi to locate the foreign body.

Removing a foreign body from the airway with a bronchoscope When the object is found, specially designed forceps are inserted into the airway through the bronchoscope to retrieve the object. This procedure requires training, delicacy and skill.

There are three kinds of forceps that may be used to remove airway foreign bodies:

• Optical forceps with an attached telescope to view the retrieval of the object
• Non-optical forceps used to remove beads, nails, screws, tacks and other objects that are in a distant tiny space
• Biopsy forceps used to remove new or granulating tissue or tissue masses, which can form as the body attempts to enclose a foreign body that has been present for an extended period

• Very rarely, the doctor may make a tracheotomy incision (an incision that opens the child's airway) to extract a foreign body that is difficult to remove due to its size or shape.

  The child will typically stay in the hospital overnight after the procedure for observation. There may be airway swelling, increased secretions, infection or difficulty breathing after the foreign body is removed. Occasionally, if a foreign body has been left in a child for a long period of time, the child may require additional bronchoscopies to make sure that all of the foreign body has been removed and that there is no residual scarring or granulation tissue. Sometimes the child requires antibiotics, steroids or inhaled bronchodilators for a brief period of time after a foreign body is removed from the airway.
