title: [Arterial Mg2+ concentrations and ECG. Changes in patients with cerebral aneurysms].
abstract: Arterial Mg2+ concentrations were analyzed in 108 patients with cerebral aneurysms. There was no difference in Mg2+ concentrations between patients with ruptured and unruptured aneurysms. Mg2+ concentrations in patients with ST depression or elevation were lower than in those without ST changes (0.34 +/- 0.05 vs. 0.38 +/- 0.07 mmol.l-1). Decreased arterial Mg2+ could be caused by cardiac ischemia rather than subarachnoid hemorrhage. For prevention of fatal arrhythmias, perioperative brain protection and ameliorating vasospasm, correcting the depressed Mg2+ concentrations is suggested.
