The deep placement group had a significantly lower incidence of complications, a delayed first complication, and a longer catheter indwelling duration.
The deep group also experienced a reduced incidence of complications and a delayed first complication. Two cases of catheter-related venous thrombosis occurred in the deep group, both in patients with multiple high-risk factors. The study is limited by its non-randomized design, single-center nature, small sample size, and uncontrolled confounding variables. Findings suggest that ultrasound-guided deep tip placement may reduce complications and prolong indwelling time, but a larger randomized trial is needed.
