Continuous Intraosseous Vascular Access Over 48 Hours

A prospective, study to determine the safety of intraosseous (IO) access for a period up to 48 hours, in healthy adult volunteers and volunteers with a history of being health-compromised, including patients with mild to moderate renal disease (National Health and Nutrition Examination Survey Stage 1 to 3) and/or patients with controlled diabetes. Subjects will be randomized to receive IO access in the proximal tibia insertion site or the proximal humerus insertion site using the EZ-IO intraosseous vascular access system. The hypothesis is that there will be no serious complications for the subjects during a 48 hour IO catheter dwell time in either place.

Inclusion criteria

• 21 years or older
• Self Identifying as having poor vascular access
• Healthy or Having at least one of the following conditions:
• Controlled diabetes, as evidenced by a glycosylated hemoglobin A1c (HbA1c) value of less than or equal to 8% at the time of screening. or
• Renal disease, Stages 1 to 3, as evidenced by the presence of albuminuria at the time of screening. Subjects albumin-creatinine ratio (ACR) must fall within the microalbuminuria or macroalbuminuria values: Microalbuminuria - ACR 17-250 mcg/mg for men; 25-355 mcg/mg for women or, Macroalbuminuria- ACR >250 mcg/mg for men; >355 mcg/mg for women
