Background
Potential adverse effects are known (acute pulmonary edema by aspiration,
anaphylactoid reactions) after administration by mouth hyperosmolar water-soluble iodinated contrast media,
although a few cases in the literature are described.
Gastrografin (BAYER Spa) is a water-soluble radiographic iodinated contrast agent,
high osmolarity.
Containing 660 mg/ml diatrizoate meglumine and 100 mg/ml diatrizoate sodium,
in gastrointestinal solution.
The contraindications are generally reported as usual to iodinated contrast media,
which must be added the special precautions in patients with suspected possibility of aspiration or broncho-oesophageal fistula,
as hyperosmolarity may cause acute pulmonary edema,
chemical pneumonitis,
and respiratory collapse death.
In these subjects,
the Gastrografin should not be given undiluted.
Is often used,
as well as the specific role of contrast enema to the digestive tract,
proposed for the end of treatment in cases of intestinal obstruction,
in neonatal and surgical.
