Static Ultrasonographic Assessment for Central Venous Catheterization Reduces Catheter Dysfunction in the Emergency Department

Abstract

This study aimed to investigate the effect of a static ultrasonographic (US) examination of the central venous structures before central venous catheterization (CVC) and the success of the procedure. In this prospective study, patients who underwent CVC, in an emergency department (ED), were divided into two groups: patients who underwent CVC using the anatomical landmark technique (n = 34) and patients who underwent CVC using a static US examination (n = 33). The procedure times, success rates, and number of catheters used were compared. A total of 67 patients who underwent CVC were included in the study. Compared with the anatomical landmark technique, the static US examination had a higher procedural success rate ( P = .001), fewer total interventions ( P = .001), and fewer postprocedural catheter dysfunctions ( P = .048). While there was no difference in the duration of the CVC between groups ( P = .222), the total time spent was longer using a static US examination ( P = .022). The static US examination was a practical, easy-to-apply method that could be used for CVC placement in an ED. This study demonstrated sonography had a high success rate in CVC procedures and contributed to a reduction in the number of interventions and catheters used.
