This systematic review and meta-analysis evaluated the effects of single-injection versus continuous brachial plexus blocks on patient-reported outcomes in 1198 adults undergoing elective shoulder surgery. Continuous blocks significantly reduced pain at rest at 12, 24, and 48 hours post-surgery, with mean differences of -1.96, -1.66, and -1.18, respectively (p < 0.001).
Key findings
- Continuous brachial plexus blocks resulted in lower pain at rest at 12 hours (MD -1.96, p < 0.001).
- At 24 hours, continuous blocks also showed lower pain at rest (MD -1.66, p < 0.001).
- Pain on movement at 24 hours approached significance (MD -2.04, p = 0.07).
- Continuous blocks improved overall patient satisfaction and comfort post-surgery.
Why it matters
Effective postoperative pain management is crucial for recovery after shoulder surgery. Understanding the comparative effectiveness of analgesic techniques can guide clinicians in optimizing patient care and enhancing recovery experiences.
