Episodes of tachycardia and hypertension, which are associated with an increase in myocardial oxygen consumption, are predictive events of these ischemia.\n\nDuring cardiac surgery by sternotomy, some maneuvers, e.g. intubation, skin incision, sternotomy and cannulation, may be associated with tachycardia and/or increases in blood pressure despite an adequate level of anesthesia. Usually these episodes are controlled by the administration of a high-dose of anesthetic agents.\n\nThe parasternal block, by bolus or continuous infusion through a single catheter, showed its effectiveness on postoperative pain after sternotomy. It allows a blocking of anterior branches of intercostal nerves at the lateral edge of the sternum; branches in charge of innervation of the sternum and the overlying skin surface.\n\nThe preoperative parasternal block, once general anesthesia performed, could provide an effective level of locoregional anesthesia of the chest wall, thus limiting the occurrence of episodes of tachycardia and / or hypertension without having to resort to massive doses of anesthetic agents during sternotomy in patients undergoing coronary bypass surgery.', 'detailedDescription': 'This randomized double blinded placebo-controlled clinical trial will include patients undergoing coronary artery bypass grafting.\n\nLocoregional anesthesia of the chest wall will be performed under ultrasound, once general anesthesia performed.
