摘要：Introduction. Magnesium (Mg) plays a crucial role in cell physiology and its deficiency may cause many disorders whichoften require intensive treatment. The aim of this study was to analyse some factors affecting preoperative plasma Mgconcentration in patients undergoing coronary artery bypass grafting (CABG).Materials and method. Adult patients scheduled for elective CABG with cardio-pulmonary bypass (CPB) under generalanaesthesia were studied. Plasma Mg concentration was analysed before surgery in accordance with age, domicile, profession,tobacco smoking and preoperative Mg supplementation. Blood samples were obtained from the radial artery just beforethe administration of anaesthesia.Results. 150 patients were studied. Mean preoperative plasma Mg concentration was 0.93 ± 0.17 mmol/L; mean concentrationin patients – 1.02 ± 0.16; preoperative Mg supplementation was significantly higher than in patients without suchsupplementation. Moreover, intellectual workers supplemented Mg more frequently and had higher plasma Mg concentrationthan physical workers. Plasma Mg concentration decreases in elderly patients. Patients living in cities, on average, had thehighest plasma Mg concentration. Smokers had significantly lower plasma Mg concentration than non-smokers.Conclusions. 1. Preoperative magnesium supplementation increases its plasma concentration. 2. Intellectual workersfrequently supplement magnesium. 3. Smoking cigarettes decreases plasma magnesium concentration.
