How Are Intralesional Corticosteroid Injections Performed?
Published: Sep 16, 2023
Intralesional corticosteroid injections are a precise medical procedure used to treat certain skin conditions. Here's a step-by-step guide on how they are performed.
Preparation and Equipment
Before performing the injection, the clinician prepares the necessary equipment: a 1 mL Luer lock syringe, a 30- or 27-gauge needle, and the corticosteroid solution. The skin is cleaned with alcohol, and the solution is mixed just before use to ensure even suspension.
Injection Technique
The needle is inserted at a 45 to 90-degree angle into the lesion, aiming for the mid-dermis layer where most inflammatory changes occur. The clinician carefully injects the corticosteroid, ensuring the skin blanches slightly, indicating correct placement.
Post-Injection Care
After the injection, gauze is placed over the site to stop any bleeding, and an adhesive bandage may be applied if needed. Hand hygiene is crucial, and needles are disposed of in puncture-resistant containers to prevent accidental injury.
