To the Editor In a recent article, Dr Morelli and colleagues1 reported a benefit of continuous esmolol infusion in patients with septic shock. In this study, administration of esmolol titrated to maintain heart rate between 80/min and 94/min was associated with a reduction of norepinephrine and fluid requirements and a decrease in mortality (28-day mortality of 80.5% in the control group vs 49.4% in the esmolol group). Because the number of patients was limited, generalization of these results should be questioned before using esmolol in the treatment of patients with septic shock.
