Abstract
INTRODUCTION The efficacy of intravenous thiamine to treat septic shock remains controversial. We conduct a systematic review and meta-analysis to explore the impact of intravenous thiamine on treatment efficacy of septic shock. METHODS We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through June 2020 and included randomized controlled trials (RCTs) assessing the effect of intravenous thiamine on septic shock. This meta-analysis was performed using the random-effect model. RESULTS Four RCTs were included in the meta-analysis. Overall, compared with control group in patients with septic shock, intravenous thiamine revealed no substantial impact on mortality (odd ratio [OR] = 0.87; 95% confidence interval [CI) = 0.62 to 1.21; P = 0.40), lactate change (standard mean difference [SMD] = 0.04; 95% CI = -0.28 to 0.35; P = 0.82), Sequential Organ Failure Assessment (SOFA) change (SMD = 0.02; 95% CI = -0.18 to 0.21; P = 0.87), intensive care unit (ICU) stay (SMD = -0.02; 95% CI = -0.33 to 0.30; P = 0.90) or renal replacement therapy (OR = 0.47; 95% CI = 0.07 to 3.15; P = 0.43). CONCLUSIONS Intravenous thiamine showed no benefit over placebo in treating patients with septic shock.
