The Effect of Esmolol on Tissue Perfusion and Clinical Prognosis of Patients with Severe Sepsis: A Prospective Cohort Study

Purpose. This study was aimed at investigating the effect of esmolol on tissue perfusion and the clinical prognosis of patients with severe sepsis. Materials and Methods. One hundred fifty-one patients with severe sepsis were selected and divided into the esmolol group () or the control group (), who received conventional antiseptic shock treatment. The esmolol group received a continuous infusion of esmolol via a central venous catheter, and their heart rate (HR) was maintained at 70–100 bpm over 72 hours. Results. The HR of all patients reached the target level within 72 hours of treatment for both groups. The effect of esmolol on PvaCO2 was only significant at 48 hours (). ScvO2 increased in the esmolol group and decreased in the control group (). Lac showed a linear downward trend over the treatment time, but the reduction was more significant in the control group at 48 hours () between the two groups. Kaplan-Meier analysis showed a significantly shorter duration of mechanical ventilation in the esmolol group than in the control group (). Conclusions. Esmolol reduced the duration of mechanical ventilation in patients with severe sepsis, with no significant effect on circulatory function or tissue perfusion.
