title: Comparison of electrolytic status (Na+, K+, Ca2+, Mg2+) in preterm and term deliveries.
abstract: OBJECTIVE
  The objective of this study was to evaluate the electrolytic status of Na+, K+, Ca+, and Mg2+ in serum and red blood cells in idiopathic preterm and term deliveries.
  
  
  METHODS
  The study included 105 pregnant women diagnosed with idiopathic premature delivery (study group) and 36 pregnant women with physiologically term delivery (controls). Samples of mother's blood were collected and analyzed for the level of electrolytes in the serum/plasma and red blood cells.
  
  
  RESULTS
  Measured values of magnesium in red blood cells in the study group were far lower than physiological values, intracellular calcium levels were higher in the study group compared to levels measured in the controls. Sodium concentrations in cells were significantly lower in subjects with premature delivery.
  
  
  CONCLUSIONS
  The magnesium intracellular level is the best representative value of magnesium in the body.
