ANESTHESIA COMPARATIVE ANALYSIS OF THE EFFECTIVENESS OF TUMISCENT METHODS, NERVE BLOCK UNDER UZ-NAVIGATION AND UNILATERAL SPINAL ANESTHESIA IN ENDOVENOUS LASER ABLATION AND MINIPHLEBECTOMY

Objective: A comparison was conducted between ultrasound-guided regional anesthesia protocols, tumescent anesthesia, and unilateral spinal anesthesia in patients with varicose vein disease of the lower extremities undergoing endovenous laser ablation and miniphlebectomy. Materials and Methods: The study assessed the impact of various anesthetic protocols on nociceptive and stress systems, as well as systemic hemodynamics, in patients with lower extremity varicose vein disease. A total of 75 patients underwent endovenous laser ablation and miniphlebectomy. The patients were selected and randomized to receive one of the following types of anesthesia: 25 patients (Group 1) underwent surgery under ultrasound-guided regional anesthesia (blockade of the femoral nerve and sciatic nerve in the popliteal fossa); 25 patients (Group 2) received tumescent anesthesia; and 25 patients (Group 3) received unilateral spinal anesthesia. Results: Ultrasound-guided regional anesthesia (blockade of the femoral and sciatic nerves in the popliteal fossa) demonstrated superior analgesic effect during the perioperative period in patients with lower limb varicose vein disease. Conclusions: Ultrasound-guided regional anesthesia more effectively mitigates surgical stress compared to tumescent and unilateral spinal anesthesia in patients with varicose vein disease of the lower extremities.
