IV CANNULA 22G

About

An IV cannula, specifically a 22-gauge (22G) cannula, is a widely utilized peripheral intravenous access device, readily identifiable by its distinctive blue hub. This particular gauge strikes an excellent balance between the ease of insertion and the achievable flow rate, rendering it highly suitable for a broad spectrum of adult patients and select pediatric applications. Its frequent clinical uses include routine intravenous fluid administration, the precise delivery of various medications, and efficient blood sampling for diagnostic purposes. The 22G cannula is often the preferred choice for patients who require moderate infusion rates or possess average-sized veins, offering a less invasive alternative compared to larger gauges while simultaneously providing sufficient robustness for the majority of common clinical requirements, ensuring effective and comfortable patient care.

Uses

• Routine intravenous fluid administration.
• Delivery of various medications.
• Blood sampling for diagnostic tests.
• Maintaining venous access for emergencies.

Directions For Use

Select an appropriate 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

• Good balance of flow rate and vein preservation.
• Suitable for a broad range of adult patients.
• Less traumatic than larger gauge cannulas.
• Facilitates routine intravenous therapies.
• Commonly available and widely used in clinical settings.
• Allows for moderate infusion rates.

Side Effects

• Phlebitis (vein inflammation)
• Infiltration (fluid leakage into surrounding tissue)
• Infection at the insertion site
• Hematoma formation
• 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.
• 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.
