While Diesetronic says that the trials for these "permanent" infusion
ports are going well, I am still a bit skeptical. The design for the
Diaport is identical to some titanium/silicone devices that were
designed for peritoneal dialysis (and really didn't work) a LONG time
ago. The big issues are:
1) anything sticking out through the skin will likely eventually have
problems with a critical infection. "Sucess" in this area depends on
what infection rate you find acceptable - 1/year, 1 per 2 years?
Serious infection requires removal/replacement of the device.
2) using a catheter device to administer insulin into the peritoneal
cavity often causes either fibrin blockage or entrapment by the
omentum (bet you haven't studied THAT organ yet!)
3) using a catheter device to administer directly into a vein also has
its own complications.
Unless the designers have come up with some major improvements in the
areas above, I still prefer changing a flexible cannula every 3-3.5
days. Not to disappoint anyone, but you'll find evidence of issues 2)
and 3) in some published trials of implantable pumps. If I remember
correctly, the fibrin blockage resulted in removal/replacement of
about 3-4% of one study's implantable pumps.
On the other hand, if they were to significantly reduce the above
issues, I might be interested. Having an almost instantaneous
response curve to insulin administration would take carb counting and
basal calculations to a new level.
