What is the maximum amount of water-soluble contrast media given to a child weighing 60 pounds?

To determine the maximum amount of water-soluble contrast media that can be administered to a child, medical guidelines generally recommend a dosage based on the child's weight. The typical calculation used for children is approximately 1 to 2 ml of contrast media per kilogram of body weight.

In this case, the child weighs 60 pounds. First, it is necessary to convert this weight into kilograms, knowing that 1 pound is approximately 0.453592 kilograms. Therefore, 60 pounds is roughly equivalent to about 27.2 kilograms (60 x 0.453592).

Applying the dosage guidelines, if we take the lower end of the recommendations, the calculation would be 1 ml per kilogram. For a child weighing 27.2 kg, this results in approximately 27.2 ml as the minimum dose. If we consider the higher end of the range, 2 ml per kilogram would yield approximately 54.4 ml.

The choice of 60 ml falls within this range. It's a standard practice to round up to ensure adequate coverage for imaging studies, and 60 ml is a reasonable maximum volume that would be safe and effective when administering contrast media to a child of that weight. This aligns with common practice and pediatric dosing guidelines,
