The management of foreign bodies in air passages

Anesthetic management of tracheobronchial foreign body removal

“…Not only that the absence of molar teeth might make the accidental migration of food particle in the airway during chewing and swallowing in haste. 1,7,8 In children, the risk is more: mainly due to physiological reduced respiratory reserve, early airway closure, increased oxygen consumption and especially increased shunting due to lung pathology that follows the obstruction of part of the lung due to tracheobronchial foreign bodies. The effect in the lung depends mainly on duration, site and degree of obstruction and also the types of foreign body, whether organic or inorganic.…”

“…The effect in the lung depends mainly on duration, site and degree of obstruction and also the types of foreign body, whether organic or inorganic. [1][2][3][9][10][11] The lungs may be emphysematous if the foreign body causes check valve effect causing obstruction mainly during expiration, collapse of the lung in ball valve effect that causes obstruction during inspiration. It may cause partial obstruction as in bypass valve without any significant radiological changes and total obstruction, as in stop valve mechanism, gives the feature of collapse.…”

“…It may cause partial obstruction as in bypass valve without any significant radiological changes and total obstruction, as in stop valve mechanism, gives the feature of collapse. 1 Almost all the authors showed the prevalence of children in their studies. 1-3 years of male children are more common to have foreign bodies.…”

“…1,2 Foreign body inhalation is an extremely serious problem in children and sometimes results in fatality. The current mortality rate from foreign body inhalation is between 0% and 1.8% according to various studies.…”

“…3,4 In spite of this, undiagnosed and unsuspected foreign bodies still occur in the airway. 1 To decrease the morbidity and mortality, and optimal outcome of the patient the close cooperation and communication between the anesthesiologists, surgeon, intensivists and the paediatrician for post operative cannot be over emphasized.…”
