Background:
Sepsis is associated with a high incidence and mortality and poses a significant challenge to the treatment. Although esmolol has shown promise in sepsis treatment, its efficacy and safety remain contentious. This meta-analysis aims to clarify the role of esmolol in sepsis management.
Methods:
PubMed, Embase, Web of Science, Cochrane library, clinicaltrials.gov and the Chinese Clinical Trial Registry were searched and references of relevant reviews and meta-analysis were also screened for appropriate studies. Keywords and free words of 'sepsis', 'esmolol' and 'randomized controlled trials' were used for search. Meta-analysis was performed using RevMan 5.3 software.
Results:
Fifteen studies involving 1100 patients were included. Compared with the control group, patients receiving esmolol exhibited significantly decreased 28-day mortality (RR, 0.69; 95% CI, 0.60 to 0.81; P < 0.0001), heart rate (HR) (SMD, -1.15; 95% CI, -1.34 to -0.96; P < 0.0001), cardiac troponin I levels (cTnI) (SMD, -0.88; 95% CI, -1.13 to -0.64; P < 0.0001), length of intensive care unit (ICU) stay (SMD, -0.46; 95% CI, -0.62 to -0.3; P < 0.0001) and duration of mechanical ventilation (SMD, -0.28; 95% CI, -0.48 to -0.09; P = 0.004) and significantly increased central venous oxygen saturation (ScvO2) (SMD, 0.66; 95% CI, 0.44 to 0.88; P < 0.0001).While, esmolol had no significant influence on norepinephrine dosage (SMD, 0.08; 95% CI, -0.13 to 0.29; P = 0.46), mean arterial pressure (MAP) (SMD, 0.17; 95% CI, -0.07 to 0.4; P = 0.16), central venous pressure (CVP) (SMD, 0.16; 95% CI, -0.04 to 0.35; P = 0.11) and left ventricular ejection fraction (LVEF) (SMD, 0.21; 95% CI, -2.9 to 0.7; P = 0.41).
Conclusion:
Esmolol reduces 28-day mortality, length of ICU stay and duration of mechanical ventilation in sepsis patients. Furthermore, esmolol improves oxygen metabolism, mitigates myocardial injury and decreases heart rate without significantly affecting hemodynamic parameters.
