Comparison of Infraclavicular And Supraclavicular Block

Summary

Ultrasound-guided brachial plexus blocks are used successfully for upper extremity surgeries. In this randomized prospective single-blind study, ASA I-II patients aged 18-65 years undergoing hand, wrist, and forearm surgery will be randomly divided into two groups. First group will receive ultrasound-guided coronal oblique supraclavicular block using a 22G, 50 mm stimulator needle, and the second group, ultrasound-guided lateral sagittal infraclavicular block using a 22G 100 mm stimulator needle. We will prepare, 30 ml of 1:1 0.5% bupivacaine and 2% prilocaine with 5 mcg adrenaline per milliliter as local anesthetic mixture. Block application time, block success, sensory and motor block levels, and postoperative analgesia time will be recorded and compared between the groups. Accordingly, the success rate of the two methods will be evaluated.

Interventions

DRUG

Bupivacaine HCl 0.5% Injectable Solution

30 ml of bupivacaine (Bupivacaine HCl %0.5) and prilocaine (Priloc HCl %2) 1:1 mixture will be prepared in a way that there will be 5 mcg adrenaline per ml. (14 ml. bupivacaine, 14 ml. prilocaine and 2 ml saline with 5 mcg adrenaline per ml.)

DRUG

Prilocaine HCl 2% Injectable solution

30 ml of bupivacaine (Bupivacaine HCl %0.5) and prilocaine (Priloc HCl %2) 1:1 mixture will be prepared in a way that there will be 5 mcg adrenaline per ml. (14 ml. bupivacaine, 14 ml. prilocaine and 2 ml saline with 5 mcg adrenaline per ml.)

DRUG

Adrenaline amp. 0.5 mg

30 ml of bupivacaine (Bupivacaine HCl %0.5) and prilocaine (Priloc HCl %2) 1:1 mixture will be prepared in a way that there will be 5 mcg adrenaline per ml. (14 ml. bupivacaine, 14 ml. prilocaine and 2 ml saline with 5 mcg adrenaline per ml.)

PROCEDURE

Ultrasound guided supraclavicular block with coronal oblique method

The blocks will be performed by an experienced anesthesiologist with a USG guidence.

PROCEDURE

Ultrasound guided lateral sagittal infraclavicular block

The blocks will be performed by an experienced anesthesiologist with USG guidence.
