Abstract
Objective The purpose of this study was to generate collated evidence on the efficacy of erector spinae plane block (ESPB) for pain control after hip surgeries. Methods All randomized controlled trials (RCTs) published on the databases of PubMed, CENTRAL, Embase, Web of Science, Google Scholar, and Open Gray up to 4 March 2023 and comparing ESPB with placebo for pain control after hip surgeries were eligible for inclusion. Results We included five RCTs. Meta-analysis showed that ESPB significantly reduced pain scores at 1 h (mean difference [MD]: −1.04; 95% confidence interval [CI]: −1.69, −0.40; I2 = 35%; p = 0.01), 3 h (MD: −0.95; 95% CI: −1.86, −0.03; I2 = 78%; p = 0.04), and 6 h (MD: −0.94; 95% CI: −1.77, −0.10; I2 = 73%; p = 0.03). However, no difference was noted for 12 h (MD: −0.33; 95% CI: −2.20, 1.53; I2 = 97%; p = 0.73) and 24 h pain scores (MD: 0.05; 95% CI: −0.58, 0.68; I2 = 71%; p = 0.87); 24 h total opioid consumption was not significantly different with ESPB and placebo (MD: −9.26; 95% CI: −24.49, 5.98; I2 = 94%; p = 0.23). Conclusion Scarce evidence shows that ESPB may not provide adequate pain control after hip surgeries. No difference in 24-h pain scores and total opioid consumption was noted between ESPB and placebo. Further RCTs shall strengthen available evidence.
