Your Midline Intravascular Catheter
What is a Midline Catheter?
A Midline Catheter is a thin, flexible tube inserted into a vein in your arm. The catheter is 8-10
centimeters long and can stay in your arm for up to 29 days. A Midline Catheter allows you to
get IV (intravenous) medicines and have blood samples drawn. Your Midline will be placed by a
trained nurse.
Dressing or Bandage
Your Midline Catheter must have a dressing that covers the place where it goes into your arm.
The dressing may be a clear dressing or gauze and tape. Under the dressing, an antimicrobial
disc is placed on the skin around the catheter to help prevent infection. The catheter is kept in
place with a device called a StatLock that secures it in your arm. Your nurse will change the
dressing every 7 days or anytime the dressing is wet, soiled or loose.
Your Midline Catheter dressing must be sealed with a waterproof cover when you shower. Tell
your nurse right away if the dressing has gotten wet or becomes loose after your shower.
Blood Draws
Your nurse may use your Midline Catheter to obtain blood samples for testing. Some tests may
not be able to be obtained from the Midline Catheter and will require a needle stick from another
Problems are rare, but can occur. Let your nurse or provider know right away if:
ξ You see blood or other drainage from the place where the catheter comes out of your arm.
ξ You have redness or swelling on the arm with the Midline Catheter
ξ You have pain in the arm, shoulder or neck on the side with the Midline Catheter
