Everything you need to know about Computed Tomography (CT) & CT Scanning


Pediatric Patients

question1. What about the use of contrast in the pediatric patient?
question2. What are the guidelines for oral contrast in the pediatric patient?
question3. What are the guidelines for IV contrast in the pediatric patient?
question4. Do pediatric patients need to be sedated for CT?
question5. What is the premedication regimen for pediatric patients for contrast allergy?
question6. Are there specific sizes of catheters used for pediatric CT?
answerThere is some variation but most use a 22 g angiocatheter or larger with power injector. Ideally a 20 g should be used.

2 ml/sec injection rate is common.

"There is variability in the size of the smallest-gauge catheter used for power injection. Forty nine percent (40/81) report a 22-guage angiocatheter is the smallest catheter used with a power injector, although up to 33% (27/81) of responders use a power injector for 24-guage angiocatheters, and this practice is supported in the literature."

" Roughly half of responders routinely administer IV contrast agents at 2.0 mL/s for contrast enhanced studies of the neck, chest, and abdomen/pelvis. Although most responders use 2.0 mL/s for routine contrast enhanced head CT studies, this examination had the most variability of IV contrast media injection rates."
