ADVANTAGES OF WALANT VERSUS SEDATION AND TOURNIQUET IN DE QUERVAIN RELEASE
You can see active movement differentiating the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB) so you can identify and release both compartments.
A De Quervain release is such a short and simple operation that eliminating the tourniquet and sedation, with their associated discomforts and inconveniences, is good for both you and the patient.
All of the general advantages listed in Chapter 2 apply to both the surgeon and the patient.
WHERE TO INJECT THE LOCAL ANESTHETIC FOR DE QUERVAIN RELEASE
Inject 10 ml of 1% lidocaine with 1:100,000 epinephrine (buffered with 10 ml lido/epi:1 ml of 8.4% sodium bicarbonate) subcutaneously in the center of the incision area.
See Chapter 1, Atlas, for more illustrations of the anatomy of diffusion of tumescent local anesthetic in the forearm, wrist, and hand.
