Abstract
In patients undergoing esophagus cancer surgery, we divided intraoperative fluid therapy into the group who mainly used acetic acid Ringer solution containing Magnesium (Mg) ions (group P) and the group who mainly used acetic acid Ringer solution without Mg ion (group V) . We measured Mg ion levels until the 3rd postoperative period. In both groups, Mg ion levels during operation were lower than pre operation levels. But when compared at the end of surgery, group P significantly inhibited a decrease in Mg ion levels. Mg ion levels in both groups were restored immediately after surgery. Therefore, using acetic acid Ringer solution containing Mg ions, which can prevent a reduction in Mg ion levels, should be recommended for esophageal cancer surgery from the viewpoint of perioperative fluids, metabolic management.
