Can parents hold their child during an echocardiogram procedure?
- A. You will be able to hold your child during the procedure.
- B. Your child can be active during the procedure, but can’t sit in your lap.
- C. Your child must lie quietly; sometimes a mild sedative is administered before the procedure.
- D. The procedure is invasive so your child will be restrained during the echocardiogram.
Correct Answer: C
Rationale: Although an echocardiogram is noninvasive, painless, and associated with no known side effects, it can be stressful for children. The child must lie quietly in the standard echocardiographic positions; crying, nursing, or sitting up often leads to diagnostic errors or omissions. Therefore, infants and young children may need a mild sedative; older children benefit from psychological preparation for the test. The distraction of a video or movie is often helpful.
