PRETERM LABOUR
Objectives: To determine the frequency of hypomagnesaemia in women withpreterm labour. Study Design: Cross sectional study. Settings: Department of obstetrics &gynaecology Nishtar Hospital Multan. Duration of Study: From 10th November 2016 to 10th May2017. Subject and Methods: A total of 219 pregnant women with singleton pregnancy, pretermlabour and parity 1 – 4 were included in the study. Women with history of diabetes, hypertensionsmoking and polyhhydramnious amniotic fluid index (AFI)>25 cm on ultrasound were excluded.Venous blood was drawn from entire subjects to evaluate the serum magnesium level and sentimmediately to laboratory for analysis venous blood samples were obtained by venepunctureand collected in lithium heparin specimen bottles. Data was collected for hypomagnesaemia.Results: Age range in this study was from 20 to 40 years with mean age of 30.356±3.60 years,mean parity 1.936± 0.96, mean gravida 2.936 ± 0.96, mean gestational age 32.000±2.25weeks and mean BMI was 27.337 ± 1.67 kg/m2. Majority of the patients were from 20 – 30 years(51.1%). History of preterm delivery was 17.4%. Majority of patients belong to middle economicstatus (66.2%). Hypomagnesaemia was seen in 37.9% patients. Conclusion: it is concludedthat low serum magnesium (hypomagnesaemia) is associated with preterm onset of labour.Maternal hypomagnesaemia may be used as a predictor of preterm labour.
