For Insulin Pump Users

Posted Jan 23 2010 12:00am

We hate to be cynical, but that seems to be the best way to look at most things lately (like that "change" promise many people seemed to fall for in 2008?).

Anyway, keep in mind the study reported here was supported by a grant provided by the makers of the Omni-Pod.

Researchers at Sansum Diabetes Research Institute and University of California, Santa Barbara have concluded that changing the height of a conventional insulin pump in relation to its tubing and infusion set can significantly impact expected insulin delivery rates. Such changes can occur during routine daily activities like dressing, sleeping or showering. The study, "Siphon Effects of Continuous Subcutaneous Insulin Infusion Pump Delivery Performance," evaluated the siphon or hydrostatic pressure action effects on continuous subcutaneous insulin infusion and was published in the January issue of Journal of Diabetes Science and Technology.

"In this study we found a pronounced siphon effect in conventional insulin pumps, which caused significant fluctuations in the accuracy of insulin
delivery rates when the pump position was moved higher or lower relative to its tubing and infusion site," said lead investigator Howard Zisser, MD, Director of Clinical Research and Diabetes Technology at the Sansum Diabetes Research Institute in Santa Barbara, CA. "Insulin pump therapy allows for precise control of insulin delivery for patients with type 1 diabetes. The unintended fluctuation in insulin delivery, which may arise from pump movement during normal daily use, can increase blood glucose variability, a risk factor for the progression of complications of diabetes. The effect of hydrostatic pressure was most significant at low basal rates and therefore these findings may be particularly important for pediatric diabetes patients, who often use insulin pumps at low basal rates."

Interestingly, it's on a financial page!
