was distributed in the pulmonary arteries and capillaries [Figure 2]b and [Figure 2]f.
On postoperative day 8, a meglumine diatrizoate
(Gastrografin) swallow study demonstrated no evidence of extravasation, and oral feedings were begun without complication.
The most commonly used contrast media in our hospital are two nonionic contrast media, Omnipaque (iohexol; 350 g/L iodine; Nycomed) and Visipaque (iodixanol; 320 g/L iodine; Nycomed), and to a much lesser extent, two ionic contrast media, Telebrix[R] (sodium meglumine ioxithalamate; 350 g/L iodine; Guerbet) and Urografin[R] (sodium meglumine diatrizoate
; 146 g/L iodine; Schering).
Organic iodides in radiographic contrast media such meglumine diatrizoate
(Renograffin, Hypaque) may be seen in the urine sediment for a brief time after injection of the dye.
Gastrografin (meglumine diatrizoate
) instilled through the PEG tube demonstrated that the PEG tube was located in the splenic flexure of the colon rather than in the stomach (Figures 1 and 2).
A meglumine diatrizoate
(Gastrografin) contrast study should be performed whenever a perforation cannot be completely confirmed or ruled out by endoscopic examination.
Mono-Poly resolving medium (MPRM; Dainippon Pharmaceutical Co.) consisted of 80 g/L Ficoll 400, 56.5 g/L sodium diatrizoate, and 113 g/L meglumine diatrizoate
; its relative density was 1.114 and osmolarity was 458 [+ or -] 10 mOsmol/L.
