Estimation of serum zinc, sodium and potassium in normotensive and hypertensive primigravida pregnant women

Abstract

Pregnancy induced hypertension (PIH) occurs at about 20 weeks in 6% to 10% ofpregnancies. PIH is a form of high blood pressure in pregnancy also called toxemia of pregnancy.It is more common in twin pregnancy or in women who had PIH in a previous pregnancy. Theexact cause of PIH is not known. A cross sectional study was done in Tikrit teaching hospital fromthe beginning of September 2007 to the end of may 2008. 46 primigravida pregnant women wereparticipated in this study (16 normotensive & 30 hypertensive women). Serum sodium, potassium& zinc were measured by a flame photometer. There are no significant differences betweenhypertensive pregnant women & normotensive pregnant regarding age, body weight, height, &BMI. The mean value of hemoglobin for hypertensive pregnant was 11.6 ± 0.11 gm/dl. While theheamoglobin value for normotensive pregnant women was 10.77 ± 0.49. There is no significantdifference between hypertensive pregnant women & normotensive pregnant regarding bloodhemoglobin. There is significant difference at p value of less than 0.01 between hypertensivepregnant women & normotensive pregnant regarding serum sodium level, which is higher inhypertensive group. Moreover, there is significant difference at p value of less than 0.05 betweenhypertensive pregnant women & normotensive pregnant regarding serum potassium level.However, there is no significant difference between hypertensive pregnant women & normotensivepregnant regarding serum zinc level.
