Randomized comparison between interscalene and combined infraclavicular-anterior suprascapular nerve blocks for arthroscopic shoulder surgery
Authors' conclusion
Compared with ISB, combined ICB-anterior SSNB results in equivalent postoperative analgesia while circumventing the risk of hemidiaphragmatic paralysis.
Study context
- Population
- Patients undergoing arthroscopic shoulder surgery under GA
- Participants
- 50 patients
- Comparison
- Combined ICB-anterior SSNB vs interscalene block (ISB)
- Primary endpoint
- Pain score in the PACU
- Follow-up
- 30 min
Methodological detailsequivalence hypothesis
- Equivalence hypothesis
Primary result
As reported in the abstract
Pain score at 30 min in PACU
- No intergroup differences in postoperative pain scores
Secondary outcomes
Complete sensorimotor blockade, intraoperative/postoperative opioid consumption, patient satisfaction at 24 h
- No intergroup differences
Safety
Hemidiaphragmatic paralysis 30 min after the block
P < 0.001
Hemidiaphragmatic paralysis in the PACU
P < 0.001
Opioid-related side effects
- No intergroup differences in side effects
