Abstract
BACKGROUND
To compare the distal radial artery approach (DRA) with a longer catheter to DRA with a shorter catheter in arterial catheter (AC) placement in the intensive care unit (ICU).
METHODS
This was a single-center retrospective cohort study of DRA with a long catheter (60 mm) for arterial catheterization in the ICU. DRA with a short catheter (25-30 mm) was used in the control group, and the groups were compared using multivariate regression analysis. The primary study endpoint was the incidence of unplanned AC removal. The secondary endpoint was the incidence of other inappropriate events, namely loss of arterial pressure waveforms, bleeding, catheter-related infection, pressure ulcer, and other complications associated with the AC.
RESULTS
In this study, the DRA with a long catheter was used in 50 patients. No unplanned AC removals or other inappropriate events occurred, and there were no complications associated with the DRA. The DRA procedural success rate was 100%. There was no significant difference in hemostasis times between the groups. Loss of arterial waveforms was an early predictor of unplanned AC removal.
CONCLUSIONS
The DRA with a long catheter provided stable monitoring and was associated with a low unplanned removal rate. This method has the advantages of fewer complications and shorter hemostasis time compared with the DRA with a short catheter, and may become a new AC option in the ICU.
