Abstract

SIGNIFICANCE: Hypertensive complications in pregnancy are the most common medical problems which have serious maternal and perinatal consequences

OBJECTIVE: The general objectives of this study is to provide epidemiological data on the profile of pregnancies complicated by hypertension at a university tertiary hospital.

METHODS: 1,646 records of patients with hypertensive complications were abstracted for the maternal demographic data, laboratory findings and fetal characteristics and outcomes.

RESULTS AND CONCLUSIONS: The prevalence of the hypertensive complications of pregnancy is 15% in a tertiary referral center, with pre-eclampsia as the most common and eclampsia as the least. Pre-eclampsia and eclampsia affect young women (22-26) years) while chronic hypertension is seen among older women (31-34 years). Pregnancy-induced hypertension is more common in primigravidas and nulliparas while chronic hypertension with or without pre-eclampsia affects multigravidas and multiparas. Eclamptics were found to have significantly higher blood pressure levels compared to the other complications. Immediately post-partum the blood pressure of patients does not significantly differ from the blood pressure on admission. Eclamptics usually deliver at preterm ages of gestation, usually by Cesarean section or by forceps. Nearly one-third to almost one-half of patients are delivered assisted by forceps. Average Apgar scores are lowest among the eclamptic patients, with relatively poorer long-term prognosis among the cases of intrapartal eclampsia. Cases of eclampsia and chronic hypertensive vascular disease (CHVD) with super-imposed pre-eclampsia are associated with higher stillbirth rates, while, cases of intra-partal eclampsia are associated with higher rates of neonatal deaths. Eclampsia is associated with significantly lower birth weights, while cases of CHVD have weights comparable with cases of gestation hypertension and mild pre-eclampsia. Severe pre-eclampsia and CHVD with super-imposed pre-eclampsia have slightly lower birth weights. The same associations are present with the proportion of small for gestation age babies. Mean hemoglobin and platelet levels are similar among the different types of hypertension. Blood urea nitrogen levels tend to be higher in cases of CHVD with superimposed pre-eclampsia and eclampsia, while the serum creatinine levels are higher among the eclamptic patients. Cases of eclampsia have lower creatinine clearance levels and higher total urine protein levels. This information may be used for planning and monitoring of these cases of hypertensive complications of pregnancy.(Author)
