Abstract:
We studied the success rate of the double catheter technique during umbilical vein catheter placement in 42 patients with a misdirected umbilical vein catheter. The misdirected catheter was left in place, and an additional catheter was inserted. X-ray films confirmed that successful placement was achieved in 50% of infants without significant adverse effects.
