Small bowel follow through for small bowel obstruction done portably

  • Patient preparation: nasogastric tube placed by clinical service, nasogastric tube set to suction for 1 hour before exam
  • Contrast used: high osmolar water soluble (Diatrizoate Meglumine – Cystograffin), if less than 8 years old use 100 cc, if great than 8 years old use 200 cc
  • Technique: inject contrast through nasogastric tube with patient in supine position and then flush tube with sterile saline, leave patient off of suction for 1 hour after beginning exam, take images up to 24 hours after beginning of exam looking for contrast to have reached colon
