‘Hole-in-one’ technique for injecting local anesthetics. Step 3: 2 mL to 3 mL are injected subcutaneously on the radial side of the proximal palm to be certain the palmar cutaneous branch is well bathed. This is also performed with very little needle movement and by allowing the tumescent spreading of the anesthetic solution to proceed in a pain-free manner. Reproduced with permission from reference 1
