Cochrane corner : perioperative beta-blockers for preventing surgery-related mortality and morbidity
| Resumo: | Randomized controlled trials have yielded conflicting results regarding the impact of beta-blockers on perioperative cardiovascular morbidity and mortality. This Cochrane systematic review assessed the impact of this intervention on mortality and cardiovascular events. Eighty-eight randomized controlled trials with 19 161 participants were included (53 trials on cardiac surgery and 35 trials on non-cardiac surgery). In cardiac surgery perioperative beta-blockers had a protective effect against supraventricular and ventricular arrhythmias but had no significant effect on mortality or on the occurrence of acute myocardial infarction (AMI), stroke, heart failure, hypotension or bradycardia. In non-cardiac surgery, beta-blockers had a protective effect against AMI and arrhythmias, but this was counterbalanced by an increased risk of death and stroke. In conclusion, perioperative use of beta-blockers appears overall to be beneficial in cardiac surgery. However, in non-cardiac surgery the substantial reduction in rhythm disturbances and AMI appears to be offset by an increase in mortality and stroke, and so the systematic use of beta-blockers in this setting is not recommended. |
