[Magnesium sulfate usage for patients during cardiopulmonary bypass].

Objective: Our study was performed in order to assess the effects of magnesium sulfate during coronary artery bypass surgery to evaluate whether perioperative intravenous infusion of magnesium, as an adjuvant agent for perioperative analgesia, affects a quality of anesthesia, reduces amounts of anesthetic and muscle relaxing drugs needed, affects adrenaline usage and nitroglycerine during anesthesia.

Methods: We investigated two patient groups, undergoing a coronary artery bypass surgery. Thirty patients (control group) have not received intravenous infusion of magnesium, 31 patients (magnesium group) have received 40 mg/kg of intravenous magnesium sulfate initially and a continuous 500 mg/h infusion during anesthesia.

[Anesthesia used in minimally invasive myocardial revascularization surgery].

As myocardial revascularisation operations without cardiopulmonary bypass are getting more popular, more facts are found about their surgical techniques. However, the questions considering their anesthesia, the protection of myocardium and other are not widely analyzed. The specific features of anesthesia in cardiosurgery, such as methods of ventilation, combination of induction and general anesthesia with epidural anesthesia, usage of cardiac protection and ischemic preconditioning, monitoring, heparin management, usage of drugs, postoperative pain management are given in this article.
