IV CANNULA 18G (GREEN) - BOX OF 50

What the Product Is

An IV (Intravenous) Cannula, also known as a peripheral intravenous catheter, is a medical device used to establish a reliable pathway into a patient's vein. The 18G (18 Gauge) size is color-coded Green globally for easy identification. This box contains 50 individually sterile-wrapped units, each featuring a sharp stainless steel needle (introducer) and a flexible, biocompatible catheter.

What it is Used For

The 18G Green Cannula is a "large-bore" device, making it a standard choice for clinical situations requiring high flow rates. It is primarily used for:

• Rapid Fluid Resuscitation: Administering large volumes of IV fluids (saline or lactated ringers) in emergency or surgical settings.

• Blood Transfusions: The wide diameter prevents the shearing or damage of red blood cells during transfusion.

• Surgical Procedures: Standard for patients undergoing major surgery who may require rapid medication or fluid delivery.

• Contrast Media Injection: Used in radiology (CT scans) where high-pressure injection of contrast dye is required.

• Emergency Medicine: Ideal for trauma patients where quick venous access and high-volume delivery are critical.

Specifications

• Gauge Size: 18G (Outer Diameter: approx. 1.3mm).

• Color Code: Green.

• Flow Rate: Typically allows for approximately 90ml to 105ml per minute.

• Length: Usually 45mm.

• Features: Integrated flash-back chamber (to confirm successful vein entry), flexible wings for secure fixation, and an injection port with a non-return valve.

How to Use (Clinical Procedure)

Note: This device must only be used by trained healthcare professionals (Nurses, Doctors, or Paramedics).

1. Preparation: Select a suitable large vein (typically in the antecubital fossa or forearm). Apply a tourniquet and clean the site with an alcohol swab.

2. Insertion: Hold the cannula by the wings and insert the needle at a 15–30 degree angle.

3. Confirmation: Watch for the "flashback" of blood in the chamber, indicating the needle is in the vein.

4. Advancement: Lower the angle slightly and advance the flexible catheter into the vein while withdrawing the metal needle.

5. Securement: Dispose of the needle in a sharps container. Secure the cannula using a transparent film dressing or surgical tape.

6. Flushing: Flush with 0.9% Sodium Chloride (Normal Saline) to ensure patency and prevent clotting.

Who it's Suitable For

• Indicated For: Adults and older adolescents requiring rapid fluid or blood delivery.

• Precautions: Not typically suitable for small children, the elderly with fragile "rolling" veins, or patients with small peripheral vessels (where a 20G or 22G would be more appropriate).

• Usage Period: Should be monitored daily and typically replaced every 72 to 96 hours according to hospital policy to prevent phlebitis or infection.

FAQ

Q: Why is it color-coded green?

A: The universal color-coding system ensures that medical staff can identify the size and flow capability of the cannula at a glance, even during high-stress emergency situations.

Q: Can this be used for children?

A: Generally, no. An 18G is quite large. For pediatric patients, smaller gauges like 22G (Blue) or 24G (Yellow) are usually preferred.

Q: Does it come with the injection port?

A: Yes, these cannulas feature a top injection port, allowing for the administration of bolus medications without disconnecting the main IV line.
