Outcome Measures

Primary Outcomes (2)

  • tissue oxygenation

    To compare the effects of infraclavicular brachial plexus block and local infiltrative anesthesia on tissue oxygenation during arteriovenous fistula (AVF) surgeries. Near Infra-Red Spectroscopy (NIRS) is a non-invasive monitoring modality which measures regional tissue oxygenation defined as percentage (%).Before surgery, NIRS probes will be placed on the thenar, antecubital regions of both hands and arms .

    beginning and every 5 minutes till the end of surgery

  • primary patency of the arteriovenous fistula

    To compare the effects of infraclavicular brachial plexus block and local infiltrative anesthesia on the primary patency of the arteriovenous fistula

    1 month after the operation

Secondary Outcomes (1)

  • 5 Point Likert Scale

    at the end of the operation

Study Arms (2)

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.

Device: NIRSDrug: Prilocaine

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.

Interventions

NIRSDEVICE

Near Infra-Red Spectroscopy (NIRS) is a non-invasive monitoring modality which measures regional tissue oxygenation defined as percentage (%).

Block group(Group B)Local group(Group L)

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

Block group(Group B)

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.

Block group(Group B)

Bupivacaine is a potent local anesthetic with unique characteristics from the amide group of local anesthetics.

Also known as: Marcaine, Sensorcaine
Block group(Group B)

Prilocaine is an amide local anesthetic secondary amine with an intermediate length of duration and quick onset of action.

Also known as: Citanest, Propitocaine, Xylonest
Local group(Group L)
