Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Therefore, the investigators tested whether nerve stimulator (NS) - guided interscalene block was inferior to ultrasound-guided block in terms of duration of postoperative analgesia for shoulder surgery.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
NS-guided interscalene block
NS-guided interscalene block is performed using 20 ml of 0.75% ropivacaine.
NS-guided interscalene block
Patients received a standard single injection interscalene block using the modified lateral approach of Borgeat. The interscalene brachial plexus was identified using an insulated needle connected to a nerve stimulator. An insulated needle attached to a nerve stimulator was used to identify the brachial plexus. Placement of the needle was considered adequate if the deltoid, triceps, pectoralis, or biceps muscle motor response was still present at 0.2 - 0.5mA. Ropivacine 0.75% 20ml was used.
US-guided interscalene block
US-guided interscalene block is performed using 20 ml of 0.75% ropivacaine.
US-guided interscalene block
Interscalene block is performed under ultrasound guidance. Linear probe is placed on the ipsilateral interscalene groove visualizing the brachial plexus located between anterior and middle scalene muscles. Using in-plane technique, an insulated needle is advanced into the brachial plexus sheath, into which 20 ml of 0.75% ropivacaine is injected
