Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Standart monitorization (ECG, peripheral oxygen saturation and non-invasive arterial pressure monitoring) will be made. Base and 5 minutes interval values will be recorded until the end of the surgery. The pads of the NIRS monitor will be placed on the thenar eminence of both hands and fixed with the help of a draipe and basal measurements will be taken and recorded. The patients will then be divided into two groups according to computer-generated table of random numbers.
Group L patients will undergo surgical cleansing and sterile draping and infiltrate %5 bupivacaine 15ml. Group B the supraclavicular areas of the patients who will undergo surgical procedures will be sterile covered after appropriate sterilization. After the brachial plexus is visualized around the subclavian artery in the supraclavicular region with the help of Samsung ultrasound device, Bupivacaine 5% 20ml and Lidocaine 2% 10ml will be applied around the brachial plexus using a 50mm stimuplex needle. The effectiveness of the block will be evaluated by a single investigator after withdrawal of the needle, either by effective anesthesia with the block or every 10 minutes up to 30 minutes. The sensory block will be evaluated with a 3 point scale and the motor block will be evaluated routinely before and after the modified bromage scale (scored between 0 and 4). After withdrawal of the treated needle, we will contact the relevant nerve dermatome with cold application (cold SF) and ask the patient to classify the degree of cold feeling from 0 to 3. Block will be considered unsuccessful if surgical block cannot be provided after 30 minutes or if the patient experiences pain at any time during the operation. The duration of anesthesia occurring after local infiltration of Group L and the sensory and motor blockade after group B stimulation is taken will be recorded. In both groups, NIRS values will be recorded at 5 minute intervals until the end of the case after local anesthetic application.
Investigator will call the patients for primer patency of fistula one month after operation.
