Summary

This study tested a new type of knife used to make a small cut when inserting a central venous catheter (a large IV line). Doctors rated how easy and safe the knife was to use, and the team tracked problems like needing to re-cut or restart the procedure. 86 patients and their doctors took part at Johns Hopkins University.
