Physiological Monitoring Strategies in Managing Pregnancy-Induced Hypertension at Secondary Healthcare Facilities in Ogun State

Pregnancy-induced hypertension is a leading cause of maternal and perinatal morbidity in Nigeria, and the adequacy of physiological monitoring at secondary care facilities significantly influences outcomes. This study assessed physiological monitoring strategies and their effectiveness in managing pregnancy-induced hypertension at secondary healthcare facilities in Ogun State, South West Nigeria. A retrospective review of 150 case files and a prospective observational component involving 80 women with pregnancy-induced hypertension were conducted across five general hospitals. Documented monitoring parameters included frequency of blood pressure measurement, proteinuria testing, foetal heart rate monitoring, and fluid balance assessment. Clinical outcomes including preterm delivery, foetal distress, and maternal convulsion were recorded. Descriptive statistics and logistic regression were applied. Results showed significant heterogeneity in monitoring frequency across facilities. Proteinuria assessment was performed consistently in only 47 percent of cases. Inadequate monitoring frequency was independently associated with increased risk of eclampsia. Foetal heart rate monitoring was absent in 38 percent of documented deliveries. The study concludes that physiological monitoring of pregnancy-induced hypertension in Ogun State secondary facilities is inconsistent and insufficient. Standardised monitoring checklists, staff training in obstetric physiological assessment, and equipment supply are urgently recommended.
