Abstract

Introduction Magnesium sulfate has many side effects on the fetus and pregnant mother. On the other hand, considering different blood supply rates to the anterior and posterior regions of the uterus, we decided to conduct this study to investigate the relationship between placental location and neonatal magnesium levels in mothers with preeclampsia. Materials and methods This descriptive study was performed on 74 pregnant women and their newborns referring to Amir-al-Momenin Hospital in Zabol city, south of Iran from 1 February, 10 2019 to Aguest, 10 2019. The data collection tool was a researcher-made checklist consisting of two parts: Information about maternal and neonatal demographic characteristics. Blood samples were taken from neonatal cord and the magnesium level was measured Results The mean +/- SD of mother's age in the case and control groups was 24.62 +/- 1.14 and 22.97 +/- 1.14 years, respectively. Neonatal blood magnesium level in case and control groups was 2.58 +/- 0.339 and 1.87 +/- 0.37, respectively. Statistical analysis showed a significant difference between the two groups only regarding neonatal weight and blood magnesium level (p = 0.001). The results also showed no relationship between placental location and neonatal magnesium level (p = 0.698). Conclusion The results of the present study indicate no relationship between the placental location and neonatal blood magnesium level, and it is thus recommended to carry out further studies with larger sample size to investigate such more accurately.
