Overview
Brief Summary
The investigators compared the postoperative analgesia of nerve stimulator-guided and ultrasound-guided interscalene block after shoulder surgery.
Detailed Description
Ultrasound (US)-guided peripheral nerve block has increased in popularity. It has many advantages such as improved success rate, faster onset time, fewer needle passes, shorter performance time, and reduced procedural pain and vascular puncture. However, there is no information about postoperative analgesia. 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.

Outcomes
Primary Outcomes
duration of postoperative analgesia
Time Frame: at 24h after surgery
time from completion of local anesthetic injection until the first request for an analgesic
Secondary Outcomes
- patient discomfort (pain score (0 -10) during the procedure)(at 30 min after block placement)
- paresthesia (presence of paresthesia during the procedure)(at 30 min after block placement)
- motor block of hand(at 30 min after block placement)
- onset time (complete block of sensory and motor nerve)(until 30min after completion of local anesthetic)
- The number of needle redirections(at 30 min after block placement)
- paresthesia of hand(at 30 min after block placement)
- Pain score(at 24h after surgery)
- Patient satisfaction(at 24h after surgery)
- block performance time (the time between the block needle insertion and needle withdrawal)(at 30 min after block placement)
- Supplemental analgesia(at 24h after surgery)
