Summary

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.

Detailed description

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 .

Conditions

• Renal Disease, Chronic

Interventions

Type	Name	Description
DEVICE	NIRS	Near Infra-Red Spectroscopy (NIRS) is a non-invasive monitoring modality which measures regional tissue oxygenation defined as percentage (%).
OTHER	Pinprick Test	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
OTHER	Modified Bromage Scale	Assessment of motor blockade uses 4 point Modified Bromage Score. 0.Normal motor function with full extension and flexion of elbow, wrist and fingers 1. Decreased motor strengths with ability to full flexion elbow and move fingers but inability to raise arm 2. More decreased motor strengths with inability to move elbow but ability to move fingers 3.Complete motor block with inability to move elbow, wrist, and fingers.
DRUG	Bupivacaine	Bupivacaine is a potent local anesthetic with unique characteristics from the amide group of local anesthetics.
DRUG	Prilocaine	Prilocaine is an amide local anesthetic secondary amine with an intermediate length of duration and quick onset of action.
