In arteriovenous fistula surgery, the effect of infraclavicular brachial plexus block and local anesthesia on tissue oxygenation and the effect of primary patency of the AV fistula is intended to research.
It is planned to include patients who are American Society of Anesthesiologists (ASA) III and between the ages of 18-80 who will undergo arteriovenous fistula surgery in the research population.In our study, patients who come to the operating room for arteriovenous fistula operation will be randomly divided into two groups.Patients who undergo simple randomization with coin toss method will be assigned to one of two groups: group Local infiltrative anesthesia (Local) and group infraclavicular brachial plexus block with 0.25% bupivacaine (Block). Local infiltrative anesthesia will be applied with 15 ml 2% prilocaine for group Local patients.For Group Block patients, 30 ml 0.25% bupivacaine will be applied with Infraclavicular approach around brachial plexus with inplane technique.Before the start of surgery, NIRS probes will be placed on the thenar ,antecubital regions of both hands and arms .The preoperative observed values and data of every 5 minutes during the operation will be recorded .

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Local group(Group L) | Active Comparator | Local infiltrative anesthesia will be applied with 15 ml 2% prilocaine for Local group patients.Before surgery, NIRS probes will be placed on the thenar, antecubital regions of both hands and arms .The peripheral regional oxygen saturation values will be recorded preoperatively and every 5 minutes during the operation. Surgeon and patient satisfaction will be evaluated by 5 Point Likert Scale (worst: 1 point, best: 5 points) at the end of the surgery. |
|
| Block group(Group B) | Active Comparator | For Block group patients, 30 ml 0.25% bupivacaine will be applied with Infraclavicular approach around brachial plexus with inplane technique.The effect of the peripheral nerve block will be evaluated with 10-minute intervals until regional anesthesia is achieved.Sensory block will be evaluated with the "Pinprick Test" and motor block with the "Modified Bromage Scale". For patients who underwent a block, Grade 2 on the "Pinprick Test" and Grade 3 on the "Modified Bromage Scale" were considered suitable anesthesia conditions for the operation. Before surgery, NIRS probes will be placed on the thenar, antecubital regions of both hands and arms .The peripheral regional oxygen saturation values will be recorded preoperatively and every 5 minutes during the operation. Surgeon and patient satisfaction will be evaluated by 5 Point Likert Scale (worst: 1 point, best: 5 points) at the end of the surgery. |

| Pinprick Test | Other | With the pinprick test, the practitioner gently touches the skin with the pin and asks the patient whether it feels sharp or blunt .Test begins distally and then move proximally (aiming to test each dermatome and each main nerve). Assessment of sensorial blockade uses 3 grade system. Grade 0.Sharp pain Grade 1.Analgesia ,numbness Grade 2.Anesthesia ,no feeling |
|
| Modified Bromage Scale | Other | Assessment of motor blockade uses 4 point Modified Bromage Score. 0.Normal motor function with full extension and flexion of elbow, wrist and fingers
