Chapter 5 Digital Block Overview 1. Two techniques can be used to perform a digital block: a. Tendon sheath injection b. Web space injection 2. The web space injection technique is more painful but provides a complete digital block more reliably. Indications for use A digital block is used for soft tissue injuries about the finger distal to the proximal interphalangeal joint. Precautions 1. Warnings not to use epinephrine in a digit are based on misinterpretations of invalidated data. 2. Do not use a digital block if the metacarpophalangeal (MP) joint is surrounded by infection. Pearls When performing a tendon sheath injection, the dorsal block can be enhanced by skirting the tendon sheath on either side and injecting on the dorsum of the hand. Equipment 1. Antiseptic: Chlorhexidine prep stick or alcohol-soaked gauze 2. Syringe: 10-mL syringe 3. Needle: a. Large-bore, blunt-tipped, drawing-up needle b. 1½-inch, 25-gauge needle 4. Anesthetic (for a typical adult): a. Lidocaine: 5 mL of 2% b. Bupivacaine: 5 mL of 0.5% 5. Sterile gloves 6. 4 × 4 inch gauze Basic technique 1. Patient positioning: Place the hand on a bedside table with the arm in pronation. Only gold members can continue reading.
