The analgesic efficacy of subacromial bursa block for arthroscopic shoulder surgery: A systematic review and meta-analysis
Authors' conclusion
Compared to systemic analgesia alone, this meta-analysis suggests that for arthroscopic shoulder surgery, the addition of single-injection SBB can reduce postoperative pain and opioid consumption for up to 18 and 24 h, respectively. In contrast, continuous SBB does not seem to improve any of the analgesic outcomes.
Study context
- Population
- Patients undergoing arthroscopic shoulder surgery
- Participants
- 679 patients · 15 RCTs
- Comparison
- SBB added to systemic analgesia vs systemic analgesia alone
- Outcome
- Postoperative analgesic consumption (oral morphine equivalents)
- Follow-up
- First 24 h postoperatively
Pooled result
As reported in the abstract
24-h postoperative morphine consumption · 24 h
SBB vs ControlMD, mg (CI)P value
Continuous SBB; no reduction
−40.36(−81.77 to 1.06)
P = 0.06- Single injection SBB
- reduction 58.98 mg (CI −100.14 to −17.81); P = 0.005
Further pooled results
Pain scores · up to 48 h
- Single-injection SBB reduced pain scores up to 18 h postoperatively
- Continuous SBB did not improve pain control at any time point
Patient satisfaction, functional scores
- No differences vs systemic analgesia alone
Safety
Adverse events
- No differences vs systemic analgesia alone
