Summary

This completed study tested whether placing an arterial line 1.5-2.5 cm higher than the usual wrist site reduces problems like kinking or blockage. 486 adults having elective surgery were randomly assigned to the modified or traditional site. The goal was to see if the new spot leads to more stable blood pressure readings and fewer line failures.
