A Meta-Analysis of the Effects of Levosimendan on Cardiac Function and Outcomes in Patients with Sepsis.

To systematically evaluate the effect of levosimendan on cardiac function and outcomes in patients with sepsis.We searched multiple databases including CNKI, VIP, WanFang Data, WOS, PubMed, EMbase, and The Cochrane Library up to February 2023. We targeted RCTs comparing levosimendan with dobutamine as a control for treating sepsis. After a rigorous screening and quality evaluation, 18 studies were selected for meta-analysis using Review Manager 5.4.Out of 18 studies involving 980 sepsis patients, the meta-analysis revealed the following for the levosimendan group compared to dobutamine: (1) A significant reduction in mortality rate (OR = 0.63, 95% CI (0.42,0.95), P = .03). (2) Shortened ICU stay (MD = -2.55, 95% CI (-3.12, -1.98), P < .00001). (3) Increased left ventricular ejection fraction (LVEF) (MD = 6.05, 95%CI (5.28, 6.81), P < .00001) and cardiac index (CI) (MD = 0.47, 95%CI (0.35, 0.59), P < .00001). (4) Decreased blood lactate (Lac) (MD = -1.31, 95%CI (-1.73, -0.90), P < .00001) and troponin I (TnI) levels (MD = -0.43, 95%CI (-0.66, -0.21), P = .0002). (5) Reduced incidence of adverse events (OR = 0.43, 95% CI (0.23,0.81), P = .008).Compared to dobutamine, levosimendan substantially enhances cardiac function in sepsis patients, leading to improved outcomes and fewer adverse events.
