Tenosynovitis Clinical Trial
Official title:
Efficacy of Tumescent Local Anesthesia in the Surgical Management of Tenosynovitis.
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).
