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

Area of Science:

• Vascular Access Devices
• Medical Device Maintenance
• Patient Safety

Background:

• Implanted ports are crucial for long-term vascular access.
• Port occlusions can cause treatment delays and impact patient quality of life.
• Heparin safety concerns drive research into alternative locking solutions.

Purpose of the Study:

• To compare the efficacy of 20 ml normal saline with the push-pause flush technique against heparin in preventing implanted port occlusions.
• To evaluate normal saline as a safer alternative to heparin for maintaining port patency.

Main Methods:

• A cohort study involving 538 patients with implanted ports over five months.
• Data collection included patient demographics, port type, locking solution, and occlusion events.
• A transition from heparin to normal saline flushing protocols was implemented during the study period.

Main Results:

• Overall port occlusion rates were low, irrespective of the locking solution used.
• No statistically significant association was found between locking solution type and port occlusion incidence.
• Preliminary data suggest normal saline with pulsatile flushing is comparable to heparin for maintaining port patency.

Conclusions:

• Normal saline, utilizing the push-pause flush technique, shows promise as an effective alternative to heparin for implanted port maintenance.
• Further research is warranted to confirm long-term efficacy and safety of saline locking solutions.
• This approach may enhance patient safety by reducing reliance on heparin.
