This study was conducted to examine the relationship between magnesium blood levels and postoperative bleeding in patients undergoing elective Coronary Artery Bypass Grafting (CABG) Surgery. Background. Decline in Serum magnesium following cardiac surgery is an important issue and postoperative bleeding is among concerns associated with postoperative care in open heart surgery. It seems that coagulation disorders related to magnesium are dose-related. Method. In this descriptive correlational study, 120 patients undergoing CABG surgery using cardiopulmonary bypass machine were enrolled. All the patients were similar regarding the process of anesthesia and surgery. After surgery, when transferring to the intensive care unit, a blood sample was obtained from patient and sent to the laboratory to measure the magnesium blood levels. The amount of blood drainage in chest bottle of patient was recorded. The data were analyzed in SPSS version 20 using descriptive and inferential statistics. Findings. There was a statistically significant inverse correlation between magnesium blood levels and postoperative blood drainage (r=-0.17, P=0.046). There was also a statistically significant correlation of Prothrombin Time (PT) and Partial Thromboplastin Time (PTT). Conclusion. Magnesium blood level is influential on blood drainage in postoperative period as well as antiarrhythmic effect. It seems there is no concern about increasing blood drainage following infusing magnesium for patients under CABG surgery. M3 ER -
