IV Catheters & Peripheral IV Catheters

IV Catheter Needles

An intravenous IV catheter – often called an IV cannula – is a thin, flexible hollow tube that is inserted into a patient’s vein to provide direct access to the bloodstream. Once in place, the IV catheter remains in the vein (the sharp introducer needle is removed), allowing health professionals to administer fluids or medications into the blood without repeated needle sticks. For example, one medical resource explains that an IV catheter is a hollow tube that a doctor or nurse can thread through a vein to provide a route to administer medications and fluids directly into the bloodstream. 

Uses of IV Catheters include:

  • Fluid and Medication Infusion: They allow safe delivery of intravenous fluids (like saline or glucose), medications (antibiotics, pain relievers, chemotherapy, etc.), blood products, or nutrients directly into the circulatory system.
  • Blood Sampling or Transfusion: IV catheters can be used to draw blood for testing without repeated needle pokes, or to infuse donated blood or plasma.
  • Emergency and ICU Use: In emergencies, IV catheters enable rapid infusion of life-saving fluids or drugs (e.g., during shock or major surgery). Central IV catheters (longer lines placed in large chest or neck veins) are used for intensive care or long-term intravenous therapy.
  • Sites of Insertion: Most IV catheters are placed in peripheral veins of the arm, hand, or leg. For long-term needs, special catheters (like PICC lines or central venous catheters) may be threaded into larger veins in the chest or neck.
  • Professional Insertion: IV catheter placement must be done using sterile technique by trained medical staff. A small needle inside the catheter helps insert it into the vein; after placement, the needle is removed and only the soft plastic catheter remains in the vein. The catheter is then secured to the skin and connected to IV tubing and a fluid source (like an IV bag) for the prescribed infusion.

In summary, an IV catheter is the essential tubing that provides a direct, reliable pathway into a vein. It is the first component of any IV infusion setup, allowing ongoing delivery of fluids or drugs into the bloodstream under medical supervision

  • Radiopaque Catheters: For visibility under imaging.
  • Closed System/Integrated Extension Set Catheters: Built in connection for reduced contamination risk.

Sizes (Gauge/Length Options)

  • Gauge Colors (international standard for fast identification):
    • 14G (orange): Large bore, trauma/resuscitation (1.5–2 inches)
    • 16G (grey): Major surgery/rapid volume (1–2 inches)
    • 18G (green): Blood transfusion, fluids, surgery (1–1.25 inches)
    • 20G (pink): Medications, routine fluids (1–1.25 inches)
    • 22G (blue): Elderly, children, routine meds (0.75–1 inch)
    • 24G (yellow): Neonate/pediatric, sensitive veins (0.75 inch)
  • Lengths usually range from 0.75 to 2 inches depending on vein depth and application.

Precautions

  • Strict Aseptic Technique: Required for insertion/removal to prevent bloodstream infection and phlebitis.
  • Monitor IV Site: Inspect regularly for redness, swelling, pain, infiltration, or infection—stop use if issues arise.
  • Secure Properly: Use approved dressings/tapes/securement devices to prevent dislodgement or kinking.
  • Single Use Only: All IV catheter needles are single-use for infection prevention—never reuse or share between patients.
  • Needlestick Safety: Use safety-engineered devices to minimize healthcare worker exposure; never recap.
  • Correct Sizing: Select the smallest gauge needed for therapy to minimize patient discomfort and vein trauma.
  • Remove Promptly: Discontinue as soon as no longer medically necessary to prevent catheter-related complications.

Depend on FDA-approved IV Catheter Needles for safe, accurate, and comfortable venous access—trusted by hospitals, infusion clinics, ERs, and home care teams.
