Normal Saline Push–Pause Advantage for Implanted Port Patency: A Comparative Study

Preliminary analysis showed low overall port occlusion rates, regardless of the locking solution used. A Fisher's exact test revealed no significant association between the type of locking solution and port occlusion. Interim findings suggest that when used with the pulsatile flush technique, normal saline may be as effective as heparin in maintaining port patency. Additional research is needed to assess the long-term implications of using saline as a locking solution.
