Clinical and epidemiological evaluation of patients undergoing surgical treatment with local anesthesia using the walant technique

Local anesthesia without tourniquet, also called WALANT, is a technique that uses the vasoconstrictive effects of adrenaline and local anesthetics of lidocaine to establish an anesthesia with hemostatic control.Allowing the active participation of the patient in the intraoperative period, the local anesthesia fully agreed without the use of tourniquet improves the patient's satisfaction to rehabilitation and produces greater patient satisfaction This study evaluated the pain of patients undergoing hand surgery using the visual analogue scale (VAS) intraoperatively, presenting the patient with a scale with numbers 0 and 10 during the surgical procedure, questioning him about the level of his pain during the procedure surgery.A prospective interventional study was carried out in which patients undergoing surgical treatment of the hand using the WALANT technique were evaluated.Of the total number of patients evaluated (n=23), 15 (65%) of the patients "did not have any complaints of pain", which according to the VAS scale is classified as zero, 6 (25%) reported feeling "mild pain", classified in 1 to 3 by the VAS scale, and 2 (8%) patients indicated "moderate pain", classified in 4 and 5 by the VAS scale.The application of the WALANT technique increased patients' comfort and convenience, allowing the patient to be discharged on the same day, almost immediately after surgery, in addition to good receptivity for this type of technique.Because it is a quick, non-bureaucratic procedure, more agile to perform the surgery, and a reduction in surgical time, this type of technique is clearly effective and safe during hand surgery procedures, with no reports of complications.
