X-ray of GIT 7 Flashcards
What can happen if a large fluid shift occurs in children after contrast administration?
Cardiac failure and pulmonary oedema can result, especially in children with significant pre-existing cardiac dysfunction.
How does temperature affect the viscosity of contrast media?
As temperature increases, viscosity decreases, allowing for increased flow rates at lower pressures.
How can warming higher viscosity contrast media help pediatric patients?
It can result in fewer adverse reactions following injection compared to contrast media administered at room temperature.
Are the treatment guidelines for allergic-like reactions in children different from those for adults?
General guidelines are similar, but pediatric doses may differ significantly from adult dosages.
What can be helpful to have in the rooms where intravascular contrast media is injected into children?
A pediatric medication chart with weight-based dosages.
What happens to iodinated contrast media after it enters the fetal bloodstream?
It is excreted via the urine into the amniotic fluid and subsequently swallowed by the fetus.
Do iodinated contrast media cross the human placenta?
Yes, they enter the fetus in measurable quantities.
What percentage of iodinated contrast medium is excreted into breast milk in the first 24 hours?
Less than 1% of the administered maternal dose.
Should iodinated contrast agents be withheld in pregnant patients if needed for diagnostic purposes?
No, withholding is not recommended.
What standard practice is followed in many countries after exposure to iodine contrast media during pregnancy?
Checking neonatal thyroid function during the first week of life.
How much of the contrast medium ingested by the infant is absorbed from the gastrointestinal tract?
Less than 1%.
What is the likelihood of direct toxic or allergic-like manifestations in the infant from ingested iodinated contrast material?
Extremely low.
What do the American College of Radiology (ACR) and the European Society of Urogenital Radiology suggest about breast-feeding after receiving intravenous contrast?
It is safe to continue breast-feeding.
What should a mother do if she remains concerned about potential ill effects to the infant?
She may abstain from breast-feeding for 24 hours, express and discard breast milk, and use pre-expressed milk to feed the infant during that period.
