When the catheter is put in, your vein may tear, or the catheter may injure a nerve. Your catheter may get blocked, and healthcare providers may need to remove or replace it. The catheter may break, bend, or move out of place. The IV medicine may leak outside your vein and cause pain, swelling, or blisters.

As with other non-blood volume expanders, hetastarch and pentastarch do not contribute to the blood’s oxygen-carrying capacity. These products can significantly dilute the concentration of red blood cells in the blood and, if given in large volumes, can lead to volume overload and congestive heart failure.
