Fig. 7From: Suprascapular nerve block is a clinically attractive alternative to interscalene nerve block during arthroscopic shoulder surgery: a meta-analysis of randomized controlled trialsA forest plot diagram showing block-related complications. The pooled data showed that SSNB group had lower incidence of Horner syndrome (MD = 0.06, 95% CI [0.02, 0.22], P < 0.0001), numb (MD = 0.05, 95% CI [0.01, 0.33], P = 0.002), subjective dyspnea (MD = 0.4, 95% CI [0.17, 0.95]), hoarseness, (MD = 0.31, 95% CI [0.1, 0.97], P = 0.04). No significant difference was found for vomiting (MD = 0.8, 95% CI [0.38, 1.68], P = 0.56), local tenderness (MD = 0.9, 95% CI [0.27, 3.02], P = 0.87)Back to article page
