Potential advantages include avoidance of general anesthesia as well as the ability to reach subsegmental bronchi which are smaller in diameter and further down the respiratory tract than the main bronchi. The main disadvantage of using a flexible scope is the risk of further dislodging the object and causing airway compromise. Bronchoscopy is successful in removing the foreign body in approximately 95% of cases with a complication rate of only 1%.After the foreign body is removed, patients should receive nebulized beta-adrenergic medication and chest physiotherapy to further protect the airway. Steroidal anti-inflammatories and antibiotics are not routinely administered except in certain scenarios. These include situations such as when the foreign body is difficult or impossible to extract, when there is a documented respiratory tract infection, and when swelling within the airway occurs after removal of the object. Glucocorticoids may be administered when the foreign body is surrounded by inflamed tissue and extraction is difficult or impossible. In such cases, extraction may be delayed for a short course of glucocorticoids so that the inflammation may be reduced before subsequent attempts. These patients should remain under observation in the hospital until successful extraction as this practice can result in dislodgement of the foreign body. Antibiotics are appropriate when an infection has developed but should not delay extraction. In fact, removal of the object may improve infection control by removing the infectious source as well as using cultures taken during the bronchoscopy to guide antibiotic choice. When airway edema or swelling occur, the patient may have stridor.
Choreoathetosis is the occurrence of involuntary movements in a combination of chorea (irregular migrating contractions) and athetosis (twisting and writhing). It is caused by many different diseases and agents. It is a symptom of several diseases, including Lesch–Nyhan syndrome, phenylketonuria, and Huntington disease and can be a feature of kernicterus (rapidly increasing unconjugated bilirubin that cross the blood-brain-barrier in infants). Choreoathetosis is also a common presentation of dyskinesia as a side effect of levodopa-carbidopa in the treatment of Parkinson disease.The use of crack cocaine or amphetamines can result in conditions nicknamed crack dancing, or tweaking respectively, described as choreathetoid.
