Comparative Analysis of Antihypertensive and Anticonvulsant Regimens in Managing Pre-eclampsia and Eclampsia: Insights from a Sudanese Retrospective Study

Abstract

BACKGROUND Preeclampsia presents with gestational proteinuria, usually after 20 weeks of gestation, and can be complicated by generalized tonic-clonic seizures of eclampsia. Particularly in countries with limited healthcare resources, preeclampsia and eclampsia are major causes of maternal morbidity and mortality. This retrospective study aimed to evaluate the presentation, management, and outcomes of 185 women with preeclampsia and eclampsia in 2 maternity hospitals in Omdurman, Sudan, between January and December 2020. MATERIAL AND METHODS An analytical retrospective study was conducted in 2 main maternity hospitals in Omdurman, Sudan, between January and December 2020. The study included 185 pregnant women with preeclampsia or eclampsia. Data on clinical and obstetric characteristics (history of the illness, comorbid diseases, parity, gravida, multifetal pregnancy, and laboratory investigations), medications used, and maternal and neonatal outcomes were obtained for the diagnosis. The data were analyzed using the SPSS version 27. RESULTS Results: The mean age was 27.2±6.3 years, with 42.7% primigravida, 30% had a triple-drug regimen, nifedipine was the most common antihypertensive (60.5%), and 17.3% of patients underwent observation only. The seizure rate was 20%, with 92.73% controlled with magnesium sulfate. The antihypertensive regimen before delivery was significantly associated with the mode of delivery (P=0.001) and maternal outcomes (P=0.047); the regimen used after delivery significantly achieved blood pressure control (P=0.043) and improved maternal outcomes (P=0.007), but not fetal outcomes. CONCLUSIONS Maternal outcomes were markedly affected by the antihypertensive drug regimens used and the patient's seizure control status, and use of anti-convulsants successfully controlled all seizures.
