What You’ll Learn
- Peripheral venous catheters / peripheral IV’s / PIV’s
- Central venous catheters / CVC / central lines
- Care of CVC’s – everything is the nurse’s responsibility!
Peripheral venous catheters / peripheral IV’s / PIV’s
- Medscape: Intravenous Cannulation Overview
- It’s up to the nurse to decide the catheter size and insertion location
- The smaller the number, the larger the catheter
- Most adult patients will have an 18-20 gauge catheter
- The antecubital space (bend of the arm) is typically a great location for quick access, however if the patient has a continuous infusion, every time they bend their arm their IV pump will alarm
- The forearm is the ideal space, as there are no bends and it can be secured well
- Nurses are responsible for inserting peripheral venous catheters
- Make sure you look up your facility’s policy on insertion and frequency of removal
- Previous practice was to change IV site every 3 days, regardless of its condition, however, research is showing that this is not associated with better outcomes and therefore renders this action needless

Central venous catheters / CVC / central lines
- Wikipedia: Central venous catheter
- Please read the article before you hate on Wikipedia! This article has really great pictures and concise definitions
- Inserted by an advanced practice provider (PA, NP) or nurse with specialty training
- Inserted for various reasons: long-term antibiotics, vasoactive medications, TPN administration, monitoring central venous pressure (although there are newer, more accurate technologies available for this now), administration of large amounts of fluid, and so forth.
- You can draw blood from them, which is very helpful/convenient
- Various locations for insertion: subclavian, internal jugular, femoral
- Think of it as a really long IV, which starts outside of the skin and ends at or around the superior vena cava (SVC)
- If you’re not sure if it truly is a central line, then look at a chest x-ray and see where the tip terminates
- It is a line straight from the outside world to the patient’s heart, therefore infection is a MAJOR concern
- Central line blood stream infections (CLABSI’s) are the name for when a patient gets an infection because of their central line. People die from these.
- Strategies to Prevent Central Line-Associated Bloodstream Infections
- CDC resources for CLABSI’s
- Be Mr. Clean with central lines… this is a BIG DEAL for the nursing staff because while an infection can occur due to improper insertion, it’s more likely to occur because of improper care… and nurses are responsible for caring for, cleaning, and accessing them.
- Why are CVC’s needed for vasoactive meds?
- These lines end in the superior vena cava. What’s right after the SVC? The right atria. The right atria has a bunch of blood in it.. Therefore, when these meds are given in a central line, they’re immediately diluted in a large amount of blood. So it’s the fact that the medication is immediately diluted with blood that makes it okay to give them in these lines, not the diameter of the catheter.
- What’s a lumen?
- See below picture, it is what is labeled as a “cap”
- There are typically 1-3 lumens
- You administer medication and draw labs from these lumens
- These lumen should have caps on them, which create a one-way valve so that blood can’t leak out and bacteria can’t creep in
- You must clean these like CRAZY every time you use them
- “Scrub the hub” – meaning, clean the cap 10x over with an alcohol swab
- Joint Commission’s informational flyer on how to “Scrub the Hub”
- KNOW YOUR HOSPITAL’S POLICY. Seriously. Know this inside and out.
- You must check and see blood return with each use
- If there is no blood return, that means a clot has formed on the end of the catheter and you can push fluid through, but because a clot is there, it’s preventing blood from being withdrawn.
- This is a major concern because the clot could dislodge and travel
- Do not use and call MD or follow existing policy when this happens
Care of CVC’s – everything is the nurse’s responsibility!
- Get rid of them as soon as we don’t need them , only get one if its really needed
- Look at the dressing frequent, change every 7 days – or per policy: increases chances of infection each time you remove the dressing
- Antimicrobial patches are frequently used at the insertion site
- Change caps with blood draws
- If it has gauze over the insertion site, look at your policy and see if you can change it before the 7 days… you can’t see the insertion site
- Clean hub.. scrub the hub ten times before access, letting it dry, or use caps..
When inserted, get all new lines.. don’t hook older tubing to a new central line
- Educate patient and family
- Talk about infection risk and encourage them not to touch it at all
- Tell them to let you know if they start to have pain/tenderness or notice redness
- Discontinue per policy
- Lay patient FLAT! This is really important
- If you pull and meet resistance, stop!
- General IV stuff
- Label your tubing
- Know how often to change tubing
- Many are 72-96 hours if continuous and 24 hours if not continuous
- Change tubing and fluid bags before shift change if needed
- It is courteous to make sure your patient has good tubing and full bags before shift change
