This prospective cohort study assessed the incidence of mechanical complications and failures during 73 central venous catheterization attempts in a Brazilian teaching hospital. The study found that less experienced operators, less specialized operators, a prior failed attempt, and two or more difficulty criteria were associated with a higher incidence of complications.
This was a prospective cohort study of 73 central venous catheterization attempts in 57 patients at a Brazilian teaching hospital. The primary outcome was the incidence of mechanical complications within 48 hours. Complications occurred in 16.44% of attempts, with hematoma (9.59%) and arterial puncture (8.22%) being most common. Factors significantly associated with complications included operator experience of less than 50 lifetime accesses (RR 7.84, p < 0.001), less specialized operators (e.g., students vs. vascular surgery residents, RR 9.74, p = 0.002), a failed attempt prior to requesting help (RR 4.50, p = 0.008), and the presence of two or more difficulty criteria (RR 5.43, p = 0.007). The findings suggest that operator experience and procedural difficulty are important factors in central venous catheterization outcomes.
