The aim of this study is to evaluate the effectiveness of the tumescent anesthesia technique in the surgical management of hand tenosynovitis. For this, an open clinical trial was conducted, which included patients with hand tenosynovitis (carpal tunnel syndrome, trigger finger and Quervain syndrome), which were randomly assigned to a group. The control group was released pulleys and ligaments with local anesthetic technique and hemostasis with pneumatic tourniquet; While the study group was released from the pulleys and ligaments with tumescent anesthesia. The study variables were: anesthesia time, trans-surgical bleeding, pain, total procedure time and tissue reperfusion time.
Introduction: The WALANT technique (Wide Awake Local Anesthesia No-Torniquet) proposes the use of local anesthesia, epinephrine and tourniquet in the areas of the hand to be repaired, making costs and time and comfort more efficient. Objective: Evaluation of the effectiveness of the WALANT technique versus regional anesthesia with tourniquet in pain control, surgical management of stenosing tenosynovitis. Material and methods: Open clinical trial including patients with the trigger finger, tunnel syndrome in the operating room, candidates for surgery, and excluding previous surgeries at the site of the injury, hemodynamic instability, peripheral vascular diseases, smoking, anxiety, or psychiatric diseases. The anesthetic method was applied to the incision sites according to the diagnosis and the proposed procedure. At the end of the test, tumescent solution and control, 1% lidocaine plus pneumatic tourniquet on the forearm at 250mmHg. The main variables were: type of anesthesia and pain during the procedure. Descriptive and inferential statistics were applied (xi2, t-student or Mann-Whitney U).

A tumescent solution is prepared with 2% lidocaine (10ml), 1:1000 epinephrine (0.4ml) and 7.5% sodium bicarbonate (4ml) dissolved in 0.9% saline solution (40ml) and applied from 3 to 20ml (depending on the pathology to be repaired) at the incision site.
Apply 3 to 20 ml at the incision site, depending on the pathology to be repaired(carpal tunnel syndrome, trigger finger or Quervain syndrome).
Level of the forearm at 250 mmHg, after exsanguination with Esmarch bandage.
Standard surgical procedure for carpal tunnel syndrome, trigger finger and Quervain syndrome.

Procedure pain: Visual Analog Scale
Evaluated by Visual Analog Scale, A subjective psychometric response scale used to measure distinct behavioral or physiological phenomena based on linear numerical gradient, with values from 0 to 10. In the value 0 the absence or less intensity is located and in 10 the greater intensity of pain.
Time frame: immediate post surgery
Bleeding
Bleeding estimated in consensus between anesthesiologist and surgeon, based on the gauze used during surgery
Time frame: immediate post surgery
Anesthesia application time
The interval of time in minutes that is required to apply the anesthetic method chosen in the area to be used
Time frame: at the beginning of the application of anesthesia
