IV CANNULA 18G

About

An IV cannula, specifically an 18-gauge (18G) cannula, is a substantial large-bore peripheral intravenous access device, distinctly identifiable by its green hub. This particular gauge is the preferred choice in clinical situations demanding exceptionally rapid fluid administration, extensive large-volume resuscitation, or swift blood product transfusions. Its robust design makes it an indispensable tool in critical care environments such as emergency departments, operating rooms, and for patients undergoing major surgical procedures or experiencing significant acute fluid loss. While the 18G cannula offers superior flow rates, its insertion necessitates larger, more resilient veins and may potentially induce greater discomfort compared to smaller gauges. Therefore, meticulous vein selection and highly skilled insertion techniques are paramount to optimize its therapeutic advantages while diligently minimizing the risk of potential complications.

Uses

• Rapid, large-volume fluid resuscitation.
• Emergency blood and blood product transfusions.
• Administration of highly viscous medications.
• Maintaining venous access during major surgical procedures.

Directions For Use

Select a large, robust vein, clean the site with an antiseptic, insert the cannula at a shallow angle, advance the catheter, and secure it with a sterile dressing.

Benefits

• Extremely high flow rate for rapid infusions.
• Essential for emergency resuscitation.
• Facilitates quick blood product administration.
• Suitable for large-volume fluid replacement.
• Robust for critical care situations.
• Allows for administration of very viscous fluids.

Side Effects

• Phlebitis (vein inflammation)
• Infiltration (fluid leakage into surrounding tissue)
• Infection at the insertion site
• Hematoma formation
• Increased pain or discomfort during insertion
• Nerve damage (rare)
• Arterial puncture (rare)
• Catheter occlusion
• Thrombosis
• Allergic reaction to materials
• Skin irritation from dressing
• Local bruising

Safety Measures

• Alcohol - Alcohol swabs are used for skin antisepsis prior to insertion. Ensure the skin is completely dry before venipuncture to prevent stinging and ensure efficacy.
• Pregnancy - Safe for use during pregnancy when medically indicated for intravenous access, especially in emergencies.
• Breastfeeding - Safe for use during breastfeeding when medically indicated for intravenous access.
• Liver - Use with caution in patients with severe liver conditions due to potential coagulopathies, increasing the risk of bleeding or hematoma during insertion.
• Kidney - Use with caution in patients with severe kidney conditions, especially those on dialysis, to preserve veins for future access and avoid inserting into an arm with an AV fistula.
• Lung - No specific direct contraindication related to lung conditions, but ensure patient comfort and positioning during insertion.
