Warnings and Precautions

• Aspiration:
  • Aspiration pneumonitis can occur in patients who have difficulty swallowing or who have a history of food aspiration.
  • If you are at high risk for aspiration pneumonitis, it should be used cautiously.
  • Stop immediately if you suspect aspiration and keep the patient hydrated.
• Hypersensitivity
  • Hypotension, wheezing and bronchospasm can all be signs of severe allergic reactions.
  • Itching, urticaria and rash may all be symptoms of mild allergic reactions.
  • For serious systemic reactions, emergency management facilities should always be on hand. Patients should be closely monitored for around an hour.
  • Atopic asthma and patients with a history if food allergies are particularly at risk.
• Leakage intra-abdominal:
  • Leakage of barium may occur in patients at high risk for gastrointestinal perforation. Barium leakage can be caused by the following conditions:
    • Carcinoma
    • Gastrointestinal fistula
    • Inflammatory bowel disease
    • Duodenal or gastric ulcer
    • Diverticulitis
    • Appendicitis is a condition that affects the intestines.
    • Grave gastrointestinal stenosis
  • Peritonitis or granulomas may be caused by barium leakage.
• Intravasation:
  • Barium embolus, which is an intravasation of barium into the vein system, is a rare side effect.
  • It could lead to life-threatening complications.
    • Pulmonary embolism
    • DIAC (Disseminated intravascular Complication)
    • Septicemia
    • Hypotension that is severe and persistent.
• Obstruction and Baroliths
  • If barium accumulation is proximal or severe, it may lead to baroliths and inspissated barsium. This can lead to abdominal pain, appendicitis, and bowel obstruction.
  • Baroliths are a serious concern for patients who are:
    • Grave stenosis in the gastrointestinal tract
    • Impaired gastrointestinal motility
    • Electrolyte imbalance
    • Dehydration
    • Constipation
    • Children with Hirschsprung or cystic fibrosis in their children
    • Patients with dementia
