RESUMO
Hypertension complicating pregnancy is an important cause of foetal and maternal mortality and morbidity. Serum sodium, potassium, calcium and magnesium were evaluated in cases with gestational hypertension and pre-eclampsia and compared with normotensive pregnant women of corresponding period of gestation. Taking urinary micro-albumin creatinine ratio as standard to predict pregnancy induced hypertension, the role of serum electrolytes to predict the same was studied. A total of 200 patients were evaluated. There were no change in serum sodium and potassium in gestational hypertensive cases as well as in pre-eclamptic cases when compared with control group. Similar results were obtained when serum calcium level was evaluated. Mean serum magnesium level (1.53 +/- 0.29 mg/dl) was significantly low in cases of pre-eclampsia, while it was 1.79 +/- 0.25 mg/dl in patients with gestational hypertension and 2.19 +/- 0.2 mg/dl in control group. Patients having gestational hypertension along with increased micro-albumin creatinine ratio had significantly low mean magnesium level (1.68 +/- 0.1 mg/dl) when compared with gestational hypertensive patients with normal microalbumin creatinine ratio (serum magnesium level 1.87 +/- 0.1 mg/dl).
