Abstract/OtherAbstract:
OBJECTIVE: To determine the efficacy of a bolus of lidocaine administered by way of the pump before releasing the aortic cross-clamp (ACC) in preventing the occurrence of reperfusion ventricular fibrillation. DESIGN: Prospective, randomized study. SETTING: University hospital. PARTICIPANTS: Patients undergoing coronary artery bypass graft surgery (n = 34). INTERVENTIONS: Seventeen patients received 100 mg of lidocaine by way of the pump 2 minutes before releasing the ACC, and a control group of 17 patients received 5 mL of normal saline. MEASUREMENTS AND MAIN RESULTS: In the control group, the incidence of reperfusion ventricular fibrillation was 70%, which was significantly decreased to 11% in the lidocaine group. A higher cardiac output after weaning from cardiopulmonary bypass was observed in the lidocaine group; this may be attributed to the lower incidence of reperfusion ventricular fibrillation and consequently the lower need for defibrillation by electric countershocks. CONCLUSIONS: The results suggest that a bolus of 100 mg of lidocaine administered 2 minutes before release of the ACC can safely decrease the incidence of reperfusion ventricular fibrillation and is associated with better hemodynamics after weaning from cardiopulmonary bypass.
