Before taking medical measures, in non-resuscitation situations you must first hurry to clarify the diagnosis.
When suspecting intussusception and choosing an auxiliary examination, the textbooks used to usually recommend a barium meal.
That was because back then there was a shortage of ultrasound machines and CT scanners, and only X-ray machines were relatively abundant.
Advances in medical technology have given doctors more options and allowed them to phase out inappropriate examination methods.
Take the barium meal, for example: it's actually quite unsuitable, because intussusception causes bowel obstruction, and doing a barium meal on top of that only worsens the obstruction.
CT involves radiation; ultrasound is the first choice as it is quick and convenient.
The emergency department of Shou'er has an ultrasound room. Carrying the child over for a scan is the fastest.
