Summary

The aim of this study was to compare the effects of two different anesthesia methods, general anesthesia and infraclavicular block, on oxidative stress and endothelial dysfunction in upper extremity forearm operations.This prospective study aims to determine the ideal anesthesia method for patients undergoing upper extremity forearm surgeries under tourniquet by comparing general anesthesia and infraclavicular block applications in terms of oxidative stress and ED related to ischemia-reperfusion injury.

Conditions

  • Endothelial Dysfunction
  • Ischemia Reperfusion
  • Oxidative Stress

Interventions

PROCEDURE

Group GA

Anesthesia induction will be performed preoxygenation with 3 minutes of 80% FiO2 , followed by intravenosus propofol 2-2.5 mg/kg and fentanyl 2 µg/kg. Rocuronium 0.6 mg/kg will be administered for neuromuscular blockade, followed by endotracheal intubation after 2 minutes of mask ventilation. Anesthesia maintenance will be achieved with inhalation of 2.5-3.3% sevoflurane with 50% oxygen and 50% air mixture, along with infusion of remifentanil at 0.1 micrograms/kg/min. ventilation will be performed using a volume-controlled.

PROCEDURE

Group IB

infraclavicular brachial plexus block will be performed in supine position with the arm adducted and flexed at 90 degrees. A mixture consisting of 15 ml of 0.5% Bupivacaine, 15 ml of 2% Lidocaine, and 30 ml of saline solution will be prepared, with equal concentrations distributed into three different syringes of 20 milliliters each. The clavicular notch will be palpated, and an ultrasound linear probe covered with a sterile sheath will be positioned in the lateral sagittal plane over this area to visualize the median, lateral, and posterior cords of the brachial plexus surrounding the axillary artery. A special Stimuplex A 22G, 100 mm needle will be used for plexus anesthesia. local anesthetic injection will be sequentially performed around the posterior, median, and lateral cords under ultrasound guidance. After confirming sensory and motor block, the operation will be commenced.
