Magnesium. 1986;5(1):24-6.
The relationship between plasma levels of magnesium (Mg) and calcium (Ca) and the plasma Ca to Mg ratios has been investigated in two groups of women. One group of 19 women required augmentation of labor with oxytocin and the control group of 50 patients had normal successful labor. The Mg levels in the plasma were significantly higher in those patients requiring oxytocin augmentation of labor and the Ca/Mg ratio was significantly lower. In the control group, 13 out of the 50 patients had Ca/Mg ratios below 3, whereas 13 out of 19 patients requiring augmentation of labor with oxytocin had Ca/Mg ratios below 3.
对两组女性的血浆镁（Mg）和钙（Ca）水平以及血浆钙镁比之间的关系进行了研究。一组19名女性需要使用催产素加强宫缩，对照组50名患者顺产过程正常。需要使用催产素加强宫缩的患者血浆镁水平显著更高，而钙镁比显著更低。在对照组中，50名患者中有13名钙镁比低于3，而在19名需要使用催产素加强宫缩的患者中，有13名钙镁比低于3。
