INTRODUCTION The analgesic comparison between perineural and intravenous dexamethasone on interscalene block for pain management after shoulder arthroscopy remains controversial. We conduct this meta-analysis to explore the influence of perineural versus intravenous dexamethasone on interscalene block for pain control after shoulder arthroscopy.
METHODS We have searched PubMed, Embase, Web of science, EBSCO and Cochrane library databases through April 2021 and included randomized controlled trials (RCTs) assessing the effect of perineural and intravenous dexamethasone on interscalene block in patients with shoulder arthroscopy.
RESULTS Five RCTs were included in the meta-analysis. Overall, compared with intravenous dexamethasone for shoulder arthroscopy, perineural dexamethasone led to similar block duration (SMD = 0.12; 95% CI - 0.12 to 0.35; P = 0.33), pain scores at 12 h (SMD = - 0.67; 95% CI - 1.48 to 0.15; P = 0.11), pain scores at 24 h (SMD = - 0.33; 95% CI - 0.79 to 0.14; P = 0.17), opioid consumption (SMD = 0.01; 95% CI - 0.18 to 0.19; P = 0.95) and incidence of nausea/vomiting (OR = 0.74; 95% CI 0.38-1.44; P = 0.38).
CONCLUSIONS Perineural and intravenous dexamethasone demonstrated comparable pain relief after shoulder arthroscopy.
