Putting a catheter in a toddler can be tricky. A new analysis looked at how ultrasound guidance changes the game in the emergency department for children aged 36 months or younger. The team combined data from 337 cases to see what really happened when doctors used real-time ultrasound versus the standard blind technique.
The results were clear. When doctors used ultrasound, the first-attempt success rate jumped to 89.7 percent. In contrast, the standard method only succeeded 72.5 percent of the time. This difference was not a fluke. The study found a statistically significant increase in success with the ultrasound approach.
The benefits went beyond just getting the tube in on the first try. The rate of dry taps dropped from 23.9 percent down to 3.6 percent. Dry taps happen when the catheter hits the urethral wall without entering the bladder. This painful mistake often requires a second attempt. The certainty of the evidence for this primary finding was rated as moderate. No serious adverse events were reported during these procedures.
