T17.91

Clinical Causes: Swallowing difficulties or dysphagia, often due to neurological conditions like stroke or Parkinson's disease Impaired consciousness or sedation from medications or alcohol consumption Gastroesophageal reflux disease (GERD), where stomach contents frequently reflux into the esophagus and potentially the airway Poor coughing reflex or gag reflex, which usually helps clear the airway Mechanical problems during medical procedures, such as intubation or feeding tube placement Rapid eating or drinking, increasing the risk of aspiration Sedative or anesthesia use during surgeries or medical procedures

Key Symptoms: Coughing or choking during eating, drinking, or medical procedures Shortness of breath or difficulty breathing Wheezing or sudden respiratory distress Chest discomfort or pain Fever or signs of infection if aspiration leads to pneumonia Voice changes or hoarseness Gurgling sounds or presence of vomitus in the throat or airway

Diagnosis Path: Diagnosis typically involves a thorough medical history and physical examination, emphasizing episodes of coughing or choking. Imaging techniques such as chest X-rays can identify foreign material or signs of aspiration pneumonia. In some cases, bronchoscopy may be performed to directly visualize the respiratory tract and locate the aspirated gastric contents. Laboratory tests can help detect secondary infections if pneumonia is suspected.

Treatment Protocols: Providing oxygen therapy to alleviate breathing difficulties Antibiotics if an infection such as pneumonia develops Bronchoscopy procedures to clear the airways if necessary Supportive care, including hydration and rest Addressing the underlying cause, like managing GERD or neurological deficits Rehabilitative therapy to improve swallowing and reduce aspiration risk
