ObjectiveTo determine the treatment effect of an optimized resuscitation strategy on prognosis of patients with septic shock.MethodsA systematic review of MEDLINE, the Cochrane Library, EMBASE, CBM, CNKI and other sources using a comprehensive strategy was conducted. All randomized controlled trials (RCTs) of treatment of severe sepsis and septic shock were included. The patients were randomized into treatment group and control group. Preplanned subgroup analysis required studies to be categorized based on early (goal-directed therapy accomplished within 6-24 hours) vs. late (initiated after 24 hours or unknown time of resuscitation implementation). Two authors independently extracted data and assessed study quality using standardized methods. Consensus was reached by conference. The Cochrance Collaboration's software RevMan 5.0 was used for data analysis.ResultsEleven studies were included in the final analysis, providing a sample of 2066 patients. The combined results demonstrated a decrease in mortality [odds ratio (OR) = 0.63, 95% confidence interval (95%CI) 0.48-0.84, P = 0.002]; however, there was statistically significant heterogeneity [P = 0.01, I(2) = 55%]. Among the early optimal resuscitation studies (n = 8) there was minimal heterogeneity [P = 0.44, I(2) = 0%] and a significant decrease in mortality (OR = 0.53, 95%CI 0.42-0.66, P < 0.00001) and incidence of multiple organ dysfunction syndrome (MODS, OR = 0.61, 95%CI 0.43-0.85, P = 0.004). For the late resuscitation studies (n = 3), there was statistically significant difference [P = 0.05, I (2)=66%], and there was no significant effect on mortality (OR = 0.89, 95%CI 0.52-1.54, P = 0.68) and incidence of MODS (OR = 0.43, 95%CI 0.17-1.08, P = 0.07).ConclusionThis meta-analysis found that the application of an early optimal resuscitation strategy to patients with septic shock imparts a significant reduction in mortality and incidence of MODS.
