Conclusion: This initial analysis reveals that the valved PASV port system is associated with significantly fewer instances of poor blood return and thus decreases the time required for nurses to obtain blood return before infusion.
PASV central venous catheters and ports (Boston Scientific Corporation, Natick, Mass) have a pressure-activated safety valve (PASV) that is designed to reduce the incidence of occlusion complications.
The current study evaluated whether rates of catheter occlusion and complications were diminished with use of the PASV port system compared with standard open-ended products currently used.
PASV catheters are constructed of implant-grade silicone, with a physical appearance similar to that of other open-ended products on the market today.
Twenty-seven patients were implanted with a PASV port and 27 with a BardPort.
Two patients in the PASV group were treated for cellulitis surrounding the port pocket that occurred in the perioperative period (before the first accession of the port).
PASV ports were associated with significantly fewer difficulties drawing blood compared with BardPorts (5.
There were no demonstrable differences in infectious complications between the PASV group and the BardPort group.
Significantly fewer incidents of poor blood draw were reported in the PASV group (5.
A previous study randomized 365 patients to peripherally placed PASV PICC lines and standard nonvalved PICC lines.
The current study suggests that the PASV valved port is associated with fewer difficulties drawing blood.
