Suprascapular Nerve Block

Background: The suprascapular nerve accounts for 70% of shoulder sensory innervations, and suprascapular nerve block (SSNB) has been shown to be effective in the relief of chronic shoulder pain including rotator cuff tendinitis, subdeltoid impingement syndrome, and adhesive capsulitis. However, this remains inconclusive for patients undergoing surgery. The present meta-analysis aimed to explore the effectiveness of SSNB for relieving acute postoperative shoulder pain. Objective: To explore the effectiveness of SSNB for relieving acute post-operative shoulder pain. Study Design: A systematic review and meta-analysis. Setting: Services of general surgery, orthopaedics, and anaesthesiology. Methods: A systematic search of studies on SSNB for post-operative shoulder pain was conducted mainly in PubMed and Scopus. The standardized mean difference (SMD) of postoperative pain scales of SSNB versus placebo was treated as the primary outcome, whereas the odds ratio of nausea of SSNB versus placebo comprised the secondary outcome. Results: The meta-analysis included 7 randomized controlled trials and 2 comparative studies comprising 681 participants in total. The quantitative analysis showed a significantly lower pain level of SSNB versus placebo in the shoulder surgery patient group (SMD: -0.33; 95% confidence level [CI]: -0.51 to -0.15), but not in the non-shoulder surgery group (SMD: 0.28; 95% CI: -0.37 to 1.93). The pooled odds ratio of nausea in the SSNB arm compared with the placebo arm was 0.20 (95% CI: 0.09 to 0.45), indicating a reduction in the incidence of nausea following SSNB. Limitations: Heterogeneity of included trials. Conclusions: SSNB significantly reduced acute post-operative shoulder pain in the shoulder surgery group but not in patients undergoing laparoscopic surgery or thoracotomy. This suggests that SSNB can be used as a method of polymodal analgesia for patients undergoing shoulder surgery; however, it is not recommended for the non-shoulder surgery patient population.

Purpose: We aimed to investigate the effectiveness of suprascapular nerve block (SSNB) in patients with hemiplegic shoulder pain (HSP).Background: SSNB is widely used in various shoulder pains, but whether it is effective in HSP remains unknown.Methods: PubMed, Cochrane Library, and Embase databases were searched to identify potential citations. Randomized controlled trials meeting the eligible criteria were included in our analysis. The primary endpoint was Visual Analog Scale (VAS) with a maximum value of 100 and a minimum value of 0. Secondary endpoints were passive range of motion (PROM) that pain starts, and the PROM mainly included abduction, flexion, and external rotation. In addition, the upper extremity Fugl-Meyer assessment (FMA) was also included in our secondary endpoints.Results: Eight studies with 281 patients were included in our analysis. For VAS, there was no obvious difference between SSNB group and control group regardless of the follow-up period (<4 weeks or ≥4 weeks), which were −6.62 (−15.76, 2.53; p = 0.16) and 1.78 (−16.18, 19.74; p = 0.85). For shoulder function, the PROM of abduction, flexion, and external rotation was similar between groups. However, motor function indicator FMA is lower in SSNB control than that in control group, with a mean difference (and 95% CI) of −2.59 (−4.52, −0.66; p = 0.008).Conclusion: SSNB is an effective way for HSP patients.Systematic Review Registration: Registration ID: CRD42021252429.
