Intragastric administration of barium sulfate to albino rats did not produce deaths until the dose reached 25% to 40% of body weight. Death was due to stomach rupture or to bowel obstruction followed by gastrointestinal hemorrhage and generalized arteriovenous thromboses which produced further toxic changes in many body organs. Barium sulfate does not appear to be a factor of significance in the acute toxicity of tannic acid-barium sulfate formulations used in diagnostic radiology.

A fatal poisoning after oral administration of barium sulfate for contrast radiography is reported. Barium sulfate is an insoluble salt and therefore is almost nontoxic. The case described here involves a 61-year-old woman who underwent two CT scans of the digestive tract with oral administration of barium sulfate during a surgical procedure. Within several hours after the first barium swallow examination the patient presented nonspecific neurologic and cardiovascular manifestations that rapidly progressed and led to death a few days later. Laboratory findings demonstrated elevated levels of barium in the blood and cerebrospinal fluid. The most likely mechanism of poisoning was progressive intravasation of barium due to stasis of contrast material related to intestinal obstruction.

Intestinal obstruction by radiolucent foreign bodies is common in sea turtles. The absence of clinical signs and the extended fasting periods in these animals means that intestinal obstructions may not be diagnosed early. Digestive tract radiographic contrast procedures were performed to evaluate the gastrointestinal transit time and intestinal obstructions in loggerhead sea turtles. Barium sulfate and nonionic iodinate contrast medium were used for radiographic contrast procedures. Contrast medium was administered via a gastric tube or into the colon. These procedures are often necessary and are useful to document intestinal obstruction and foreign objects. The diagnostic procedures were not easily performed in some turtles, but often they were adequate for the diagnosis.

Barium peritonitis is extremely rare, but is difficult to treat and may be life-threatening. Barium suspension leakage from the gastrointestinal tract into the abdominal cavity has a time-dependent and synergistically deleterious effect in patients who have generalized bacterial peritonitis. The severity of barium peritonitis is dependent on the quantity of barium in the abdominal cavity. Barium sulfate leakage results in hypovolemia and hypoproteinemia by worsening the exudation of extracellular fluid and albumin. Abdominal fluid analysis is a useful and efficient method to diagnose barium peritonitis. Serial radiographs may not be a reliable or timely diagnostic technique. Initial aggressive fluid resuscitation and empirical broad-spectrum antibiotic treatment should be instituted promptly, followed quickly by celiotomy. During exploratory surgical intervention, copious irrigation and direct wiping with gauze are employed to remove as much barium as possible. Omentectomy should be considered when needed to expedite barium removal. Despite aggressive medical and surgical treatments, postoperative prognosis is guarded to poor due to complications, such as acute vascular shock, sepsis, diffuse peritonitis, hypoproteninemia, electrolyte imbalance, cardiac arrest, small bowel obstruction related to progression of granulomas and adhesions in the abdominal cavity. Therefore, intensive postoperative monitoring and prompt intervention are necessary to maximize chances for a positive outcome. For those that do survive, small bowel obstruction is a potential consequence due to progression of abdominal adhesions.
