- W2065304512 abstract "In Brief BACKGROUND: 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. METHODS: We searched electronic databases for randomized placebo-controlled trials of the perioperative use of esmolol in noncardiac surgery. We abstracted data on design, demographics, hemodynamic changes (planned or unplanned), myocardial ischemia, and MI. Heterogeneity was assessed via meta-regression. RESULTS: Our search identified 67 trials, which were well matched for study characteristics. The quality of the studies was limited by small sample size and poorly defined allocation concealment. Overall, the analysis demonstrates an increased incidence of unplanned hypotension (OR 2.13; 95% confidence interval [CI], 1.48 to 3.04), which was found to be dose related (R2 = 0.408). An increased incidence of significant bradycardia was not demonstrated (OR 1.18; 95% CI, 0.69 to 2.02). Dose titration was shown to influence both the change in arterial blood pressure and heart rate. In comparison with placebo, esmolol decreased the frequency of myocardial ischemia in the 7 evaluating studies (OR 0.17; 95% CI, 0.02 to 0.45). We did not assess the effects of esmolol on the incidence of MI or stroke because the incidence of these events was too infrequent in the retrieved studies. CONCLUSION: 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. Published ahead of print December 2, 2010" @default.
