Ekstrakorporeal Sirkülasyonun Magnezyum Metabolizması Üzerine Etkisi
Abstract
In 8 cases that underwent closed commissurotomy, serum magnesium was determined preoperatively, immediately after surgery, and at the 24th hour postoperatively, and in 23 patients that underwent open heart surgery, it was determined preoperatively, during the pump, immediately after surgery, and at the 24th hour postoperatively. Although magnesium was not added to the hemodilution fluid in 13 of the 23 cases that underwent open heart surgery, 2 mEq magnesium was added to 1000 ml of Ringer lactate added to the pump in 10 cases. It was determined that there was no change in serum magnesium in cases that underwent closed commissurotomy, and in those that underwent open heart surgery, serum magnesium decreased most significantly during the pump and remained low in the early postoperative period in the group that did not receive magnesium, but this value did not show a significant difference from the control group in which magnesium was added to the pump. Although magnesium levels remained low at 24 hours postoperatively in both groups, they did not show any significant statistical difference from controls. It was suggested that hemodilution, hyperaldosteronism, hyperparathyroidism and diuretic use may be responsible for hypomagnesemia, and the importance of magnesium addition to the pump was emphasized, especially in terms of preventing early postoperative arrhythmias. The relevance of hypomagnesemia to early thromboembolic complications was discussed. The literature on this subject was reviewed.
