Vascular Access Devices-So many to choose from with infusion therapy

Vascular Access Devices

Think about this for a while; at any given time; more than half to three quarters of all patients receive some form of intravenous care or medication during their hospital stay.  Intravenous therapy can range from normal saline to total parenteral nutrition, chemotherapy, electrolytes, antibiotics, narcotics or a combination of these parenteral therapies. Nurses are currently infusing several hundred various types of medications, intravenous solutions, and/or blood products.  Patient venous access may vary from poor vascular integrity, poor circulation, good vascular integrity, and excellent blood flow or a combination of each the aforementioned.
Nurses must have a good understanding of why everyday peripheral intravenous therapy fails.   It is often that the characteristics of the intravenous medications and/or solutions provided to the patient and through their given vascular access device that the primary factor venous access devices do not last longer than 24-48 hours in most cases; specifically peripheral venous access devices (PIV). The drug compositions in a lot of medications we are infusing today have a high osmolarity as well as high Ph level.  What does that mean for you, the everyday floor/staff nurse?  It means a lot for you and the patient.   It is important, to evaluate and understand the drug pH and osmolality when selecting a venous access device to complete patient’s intravenous therapy as this can help prevent complications and as well as extend the lifetime of the catheter.
