Brief summary

It is compared that combined suprascapular and infraclavicular nerve blocks to interscalene nerve block for clinical outcomes after shoulder surgery

Detailed description

In this study, the investigators planned to investigate postoperative pain, analgesic dosage, respiratory effects of the block and side effects of patients undergoing general anaesthesia after arthroscopic shoulder surgery under preoperative interscalene nerve block or suprascapular + infraclavicular nerve block.

Interventions

OTHERInterscalene block

30 minutes before anaesthesia induction interscalene nerve block will be applied with ultrasound guidance with %0,25 bupivacain 20 cc .The sham block consisted of after patients were placed in the lateral decubitus position skin preparation, ultrasound scanning of the suprascapular region, and a dry-needling, all performed to preserve patient blinding in the ISB group patients.

OTHERsuprascapular and infraclavicular nerve block

30 minutes before anaesthesia induction suprascapular with %0,25 bupivacain 10 cc .and infraclavicular nerve block with %0,25 bupivacain 10 cc will be applied with ultrasound guidance
