2. Vein Visibility: Opt for veins that are easily identifiable and more prominent.
3. Vein Integrity: Avoid veins that are sclerotic or have visible thrombophlebitis.

Vein Preparation

To prepare the selected vein, follow these steps:

Applying Tourniquet

a. Wrap the tourniquet around the patient’s limb, proximal to the intended site.
b. Tighten the tourniquet until the veins become prominent but not to the point of causing discomfort or compromising circulation.

Cleaning the Site

a. Using an alcohol swab, clean the intended insertion site in a circular motion, starting from the center and moving outward.
b. Allow the site to air dry completely before needle insertion.

Needle Insertion

Follow these steps for needle insertion:

1. Hold the needle like a pencil or dart, stabilize your hand, and aim at an angle of 15-30 degrees to the skin.
2. Pierce the skin and locate the vein by redirecting the needle until you observe a flashback of blood in the syringe.
3. Upon observing the flashback, lower the angle to approximately 5-15 degrees.
4. Advance the needle slightly further into the vein while ensuring minimal resistance is encountered.

Catheter Insertion

After needle insertion, follow these steps to insert the catheter:

1. Holding the catheter hub, gently advance it into the vein while retracting the needle.
2. Maintain control over the catheter with your non-dominant hand to prevent it from moving out of the vein.
3. Advance the catheter 0.5-1 inch beyond the needle tip.
4. Release the tourniquet once the catheter is secured to avoid unnecessary venous dilation.


Difficulties Encountered

While placing an IV line, healthcare professionals may encounter certain obstacles. Here are some challenges and their possible solutions:

1. Vein Collapse: Vein walls may collapse due to excessive pressure or improper technique. To address this, release the tourniquet and remove the catheter immediately.
a. Apply pressure at the insertion site to prevent hematoma formation.
b. Locate another suitable vein and start the procedure again.

2. Infiltration: Infiltration occurs when the IV fluid leaks into surrounding tissues instead of remaining within the vein. Recognize the signs (e.g., swelling or coolness at the site) and take prompt action:
a. Stop the infusion immediately.
b. Remove the catheter and apply warm compresses to the affected area.
c. Document the occurrence and any interventions taken.

Alternative Routes for IV Placement

In situations where peripheral IV access is challenging, healthcare professionals can consider alternative routes:

Intraosseous (IO) Line Placement

An IO line involves inserting a needle or catheter into the bone marrow cavity. This technique is primarily used in emergency situations when peripheral IV access is not possible or delayed. Special IO needles and IO infusion systems are available for this purpose.

Central Venous Catheter (CVC) Placement

Central venous catheters are placed in large central veins, such as the internal jugular, subclavian, or femoral veins. This route is chosen when long-term IV therapy, frequent blood sampling, or the use of irritant medications is anticipated.

Aftercare and Maintenance

Once an IV line is successfully placed, proper aftercare and maintenance are crucial to ensure its longevity and reduce complications. Follow these steps:

Securing the IV Line

Proper securing of the IV line prevents accidental removal or displacement. Use transparent dressings or sterile adhesive tape to fixate the catheter hub and stabilize the line.

Flushing and Dressing

Regular flushing of the IV line maintains patency and prevents clot formation. Follow the following steps:

1. Use sterile saline or heparin flush solutions.
2. Scrub the end of the catheter hub with an alcohol swab.
3. Attach a syringe filled with flush solution securely to the catheter hub.
4. Slowly inject the flush solution, observing for any resistance.
5. Apply an appropriate dressing around the IV site while ensuring good adherence.

Monitoring for Complications

Monitor the IV site and the patient for any complications or signs of infection, such as redness, swelling, pain, or warmth. Document any findings and take prompt action as necessary, involving the healthcare team if required.
