How to Properly Administer Corticosteroid Injections

Corticosteroid injections are a common and effective treatment for reducing inflammation, alleviating pain, and managing various musculoskeletal conditions such as arthritis, bursitis, tendinitis, and joint injuries. When administered correctly, these injections can provide rapid relief and improve the patient’s quality of life. However, improper technique or inadequate knowledge can lead to complications, including infection, tissue damage, or suboptimal outcomes. This comprehensive guide outlines the essential steps and considerations to ensure the proper administration of corticosteroid injections.

Understanding Corticosteroid Injections

Corticosteroids are synthetic drugs that mimic the hormone cortisol produced by the adrenal glands. They possess potent anti-inflammatory properties which make them suitable for localized treatment of inflammatory conditions. Common corticosteroids used include triamcinolone, methylprednisolone, and dexamethasone.

The primary goal of administering corticosteroid injections is to deliver the medication directly into the affected area, maximizing therapeutic efficacy while minimizing systemic side effects. Proper technique is vital to achieving optimal results and avoiding complications.

Pre-Procedure Preparation

Patient Assessment and Consent

Prior to the injection, conduct a thorough assessment of the patient’s medical history, allergies, current medications, and contraindications such as infections or bleeding disorders. Obtain informed consent after explaining the purpose, benefits, risks, and alternatives to the procedure.

Equipment and Supplies

• Sterile gloves
• Antiseptic solution (e.g., chlorhexidine or povidone-iodine)
• Sterile drapes and gauze
• Syringe (typically 1-5 mL depending on the site)
• Needle (commonly 22–25 gauge, 1–1.5 inches long)
• Corticosteroid preparation (with or without local anesthetic such as lidocaine)
• Sharps disposal container

Patient Positioning

Position the patient comfortably to allow optimal access to the injection site. Proper positioning reduces discomfort and facilitates accurate needle placement. Support the affected limb or joint with pillows or cushions as needed.

Technique for Corticosteroid Injection Administration

Proper technique involves meticulous steps to enhance safety and efficacy. The following procedural outline provides guidance:

Step 1: Hand Hygiene and Aseptic Technique

Wash hands thoroughly with soap and water or use an alcohol-based hand sanitizer. Don sterile gloves to maintain asepsis throughout the procedure. Prepare all equipment in a sterile field, ensuring sterility of needles, syringes, and medication vials.

Step 2: Skin Preparation

Cleanse the skin over the injection site with an antiseptic solution using a circular motion moving outward from the center. Allow the area to dry completely to reduce microbial contamination.

Step 3: Anesthesia (Optional)

If necessary, administer a local anesthetic such as lidocaine via infiltration to minimize patient discomfort, especially in sensitive areas or for larger joints. Wait several minutes for anesthesia to take effect.

Step 4: Needle Insertion

1. Hold the syringe with a steady grip, aligning it with the planned needle trajectory.
2. Insert the needle at the designated entry point, angling appropriately based on the target tissue and anatomy.
3. Advance the needle slowly until reaching the intra-articular space, bursa, or soft tissue plane, guided by anatomical landmarks and, if available, imaging support.

Step 5: Aspiration

Before injecting, aspirate gently to check for blood or synovial fluid, indicating entry into a blood vessel or joint space. If aspiration yields blood or unexpected fluid, withdraw the needle slightly and reassess the position.

Step 6: Injection of Corticosteroid

Inject the corticosteroid solution slowly, observing resistance and patient response. If combining with local anesthetic, inject it first or simultaneously, depending on protocol. Be cautious to avoid extravasation or unintentional tissue infiltration.

Step 7: Needle Withdrawal and Post-Injection Care

• Withdraw the needle smoothly and apply gentle pressure with sterile gauze to control bleeding and promote clotting.
• Apply a bandage if necessary.
• Inform the patient about post-procedure expectations, including potential soreness, swelling, or skin changes.

Post-Procedure Management and Follow-Up

Advise patients to rest the affected area for a few hours post-injection. Apply ice packs to reduce discomfort and inflammation. Monitor for adverse reactions such as increased pain, signs of infection, or allergic responses.

Schedule follow-up visits to assess the effectiveness of the injection and determine if additional treatments are needed. Educate patients on recognizing symptoms of complications like persistent swelling, redness, warmth, or fever, prompting immediate medical attention.

Potential Complications and Their Prevention

• Infection: Maintain strict aseptic technique; use sterile equipment.
• Subcutaneous tissue atrophy: Avoid high doses and improper injection depth.
• Joint damage or cartilage destruction: Limit frequency of injections and adhere to recommended dosages and intervals.
• Bleeding or hematoma: Screen for bleeding disorders; apply adequate pressure after withdrawal.
• Anaphylaxis or allergic reactions: Review allergy history prior to injection.

Special Considerations

Different anatomical sites require tailored approaches. For example, intra-articular injections into the knee involve different landmarks compared to shoulder or wrist injections. Use imaging guidance, such as ultrasound or fluoroscopy, when indicated, to increase accuracy and safety.
