Study Notes
IV Insertion Techniques
- Topical anesthesia: Apply topical anesthetic cream (e.g., lidocaine) 30-60 minutes prior to insertion to reduce pain and discomfort.
- Vein distension: Use a tourniquet or have the patient clench their fist to distend the vein, making it easier to access.
- Insertion angles: Use a 10-20° angle for adults and a 5-10° angle for pediatric patients to facilitate smooth insertion.
- Needle advancement: Advance the needle slowly and smoothly, maintaining a steady pressure, to reduce discomfort and vessel damage.
Vein Assessment
-
Vein selection: Choose a vein that is:
- Visible and palpable
- Straight and not tortuous
- Not recently used or damaged
- Not near a joint or area of flexion
-
Vein size: Select a vein that is:
- At least 2.5 mm in diameter for adults
- At least 1.5 mm in diameter for pediatric patients
-
Vein patency: Assess for vein patency by:
- Observing for visible signs of blood flow
- Performing a gentle tug test to ensure the vein is not thrombosed
IV Fluid Management
-
Fluid selection: Choose a fluid that:
- Matches the patient's electrolyte and fluid needs
- Is compatible with the patient's medications and medical conditions
-
Flow rate: Adjust the flow rate based on:
- Patient's fluid needs and medical condition
- IV fluid type and concentration
-
Monitoring: Monitor the patient's:
- Fluid status and electrolyte levels
- IV site for signs of complications
Complication Prevention
-
Infection prevention: Use:
- Sterile gloves and equipment
- Chlorhexidine gluconate for skin preparation
- Transparent dressings to facilitate site monitoring
-
Phlebitis prevention: Use:
- A gentle insertion technique
- A secure and stable dressing
- Regular IV site rotation and monitoring
-
Allergic reaction prevention: Monitor the patient for signs of:
- Allergic reactions to IV fluids or medications
- Anaphylaxis
Catheter Selection
-
Catheter type: Choose a catheter that:
- Is suitable for the patient's vein size and type
- Is compatible with the IV fluid and medication
- Has a low risk of complications
-
Catheter size: Select a catheter that:
- Is appropriate for the patient's age and weight
- Is suitable for the IV fluid flow rate
-
Catheter material: Choose a catheter made from:
- A biocompatible material (e.g., silicone or polyurethane)
- A material that reduces the risk of thrombosis and infection
