Review Meta AnalysisThe safety of perioperative esmolol: a systematic review and meta-analysis of randomized controlled trials.
Although β blockers have been found to decrease perioperative myocardial infarction (MI), β-blocker-mediated hypotension is associated with postoperative stroke and mortality. In this systematic review we assessed the safety and efficacy of the β1-specific, adrenergic receptor antagonist esmolol in noncardiac surgery. Safety was assessed by analyzing the incidence of postoperative hypotension and bradycardia, and efficacy was assessed by analyzing the incidence of myocardial ischemia. ⋯ This review suggests that titration of esmolol to a hemodynamic end point can be safe and effective. Safety data from studies in higher-risk patients are needed to establish a perioperative safety and efficacy profile of esmolol.
