Abstract:Objectives: Heparinized continuous-flush solutions are used to maintain arterial catheter patency. We sought to compare the patency and pressure wave integrity of radial artery catheters maintained with heparinized or nonheparinized infusions. Methods: Patients in the emergency room and intensive care unit were consecutively enrolled and randomly assigned to receive a heparinized solution (heparin group, n = 18) or normal saline (NS group, n = 16). The functional duration of radial artery catheters, the differ… Show more
