Training for ultrasound-guided implantation of central venous catheters eliminates venolysis in pediatric patients

Background: In the pediatric setting, the procurement of vascular access can be particularly difficult. Surgical venolysis was the first technique described but, in recent years, the literature has shown that ultrasound-guided implantation has fewer complications. The principal aim of this paper is to state how after a structured training to place ultrasound-guided central lines, venolysis was definitively abandoned in our hospital. We also analyzed the impact of training on the duration of procedures. Finally, the number of procedures performed per operator to maintain the quality standard achieved. Method: In this observational retrospective study, we analyzed data from 2013 to 2020 of 1497 pediatric and neonatal central venous access placements in a single center during a training path. Results: Venolysis performed by the pediatric surgeons was used in 11% of total placements, the most in the smallest patients (76.1%, <1 year of age). With the implementation of training, this invasive technique became obsolete to the point where it was no longer practiced (24.6% of vascular placement in 2013 to 0% in 2020). In the placement performed by the pediatric anesthesiologists, time progressively decreased from 51.5 min in 2013 to 29.4 min in 2022. From the analysis of the number of procedures performed by pediatric anesthesiologists, the first consultant involved performed averaging 48 procedures per year, while the other consultants had an overall average of 16.7-25 placements per year. Conclusion: Echo-guided vascular cannulation was found to be safe, reliable, and reproducible in pediatric patients and neonates and permits to deletion definitively venolysis. Well-structured training is essential and should be standardized in the future.
