About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients scheduled for elective shoulder surgery under general anesthesia with suprascapular + infraclavicular nerve block or interscalene nerve block for any reason ASA 1-3 patients

Exclusion criteria

  • Diabetes
  • coagulopathy
  • local anesthetic allergy
  • chronic opioid users
  • neurological deficit of the surgical limb
  • obstructive or restrictive pulmoner disease
  • inability to understand pain scores

Treatment and study plan

Interscalene block

Other

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.

suprascapular and infraclavicular nerve block

Other

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

Primary outcomes

  1. postoperative pain: numeric rating scale (NRS)

    Time frame: postoperative 30. minute, 4. hour, 8.hour,12. hour, 24. hour, 48. hour

    postoperative pain will be evaluated by numeric rating scale (NRS) .

Secondary outcomes

  1. phrenic nerve paralysis evaluated with ultrasound

    Time frame: thirty minutes after the nerve block

    Thirty minutes after the block, M-mode ultrasound examination of the ipsilateral hemidiaphragm was performed to measure diaphragmatic excursion.
