Understanding IV Therapy
Intravenous (IV) therapy is a method of delivering fluids, medications, or nutrition directly into the bloodstream for immediate absorption and use by the body.
IV Equipment Overview
Key IV equipment includes the catheter, IV fluid bag, tubing, tourniquet, gloves, antiseptic wipes, and a securing device. Sterility is crucial to prevent infection.
Choosing the Vein
Common sites for IV insertion are the veins of the forearm. The cephalic, basilic, and median cubital veins are typically used due to their size and accessibility.
Insertion Technique
The insertion technique involves hand hygiene, wearing gloves, vein distension using a tourniquet, skin cleansing, and precise catheter insertion at a 10-30 degree angle.
Securing the IV
After blood return is confirmed, the IV catheter is advanced, the needle removed, and the catheter secured with a sterile dressing to prevent movement and infection.
Monitoring for Complications
Post-insertion, it's crucial to monitor for phlebitis, infiltration, extravasation, or infection. Signs include redness, swelling, pain, or pus at the insertion site.
Advanced Insertion Techniques
Ultrasound-guided IV insertion is a technique used for patients with difficult vein access, improving success rates and reducing complications.
