Barium sulfate aspiration.

چکیده
A woman was evaluated for dyspnea after she inhaled barium sulfate during an upper gastrointestinal barium study that was administered by means of a percutaneous endo scopic gastrostomy tube. A plain radiograph of the chest revealed alveolar barium sulfate depositions (arrows) in the middle lobe of the right lung and in the lower lobes and the posterior aspects of the upper lobes of both lungs (image). Because of substantial hypoxia (SpO2, 58.4%), the patient was transferred to the intensive care unit, where she received endotracheal intubation and mechanical ventilator support for 2 weeks. The patient then underwent tracheotomy and was discharged to a long-term acute care hospital, where she continued to receive ventilator support. At 2-month follow-up, the patient’s symptoms had not improved, and she needed intermittent ventilator support. Oral barium sulfate aspiration is an uncommon but well-reported complication of upper gastrointestinal contrast material studies and is associated with a mortality rate of 30% to 50%.1 Postural techniques (eg, lying on the side, rotating the head, moving the head downward so the chin touches the neck) may minimize the risk of aspiration during oral administration of barium sulfate.2 Although a well-recognized complication of oral administration, aspiration can still occur with direct gastric instillation. Clinicians should pay attention to the postural support of patients undergoing direct gastric instillation.

Massive barium sulfate aspiration during upper gastrointestinal contrast material study in an elderly patient with dysphagia
Barium sulfate is an inert material used as a radiographic contrast medium during upper gastrointestinal contrast studies for evaluation of patients with dysphagia. Oral barium aspiration is an uncommon but wellreported complication of this procedure. While barium aspiration of small amounts may not cause any symptoms, massive barium aspiration can be life-threatening, particularly in elderly p...

The barium is often used in radiocontrast examinations of the digestive system because of mucosal absorption is limited. Massive barium aspiration is a rare complication, especially when there is no anatomic or neurological defi cit. The depending on barium concentration can cause various lung effects. When the literature is reviewed, barium aspiration may be asymptomatic or lethal in massive a...

We describe a case of bilateral inhalation of barium in an infant following a barium swallow for investigation of dusky spells associated with feeds. A bronchoscopy subsequently revealed the presence of a mid-tracheal tracheo-esophageal cleft. To date, little has been reported on barium aspiration in children and there is no consensus for management. We review the literature on barium aspiratio...
