Intraosseous infusions: an important but forgotten method of vascular access.
Patients with malignancies or other prolonged illnesses such as acquired immune deficiency syndrome, require long-term vascular access. Unfortunately, currently available technologies which access the vascular system, such as intravenous catheters (external or implanted ports), have frequent complications including clotting and infection which limit their long-term usefulness. An important but forgotten method to access the central venous system is through the intraosseous route. This review summarizes past experience with the intraosseous route of access to the central venous system as well as describes a new device which might eventually make intraosseous access more convenient for the patient. It is anticipated this forgotten method of vascular access will be used more frequently in patients who have exhausted conventional venous access systems.
