ABSTRACT

Background: In severe preeclampsia, the lack of blood pressure average is a factor for adverse renal function.
Objective: To describe the control of blood pressure mean and its correlation with the endogenous creatinine clearance in severe preeclampsia treated with three oral antihypertensive agents
Patients and methods: cross-sectional study on 123 pregnant women with severe preeclampsia, treated with 500 mg every 8 h methyldopa, hydralazine 50 mg every 6 h, or 100 mg of metoprolol every 12 hours from admission to the unit intensive care to the care delivery. A time of delivery were compared blood pressure average endogenous creatinine clearance and the correlation between two of the 123 patients were divided into two groups with matching blood pressure treatment goal of ≤ 95 mmHg half: group A, ≤ 95 mmHg ( 25 cases, 20.33%) and group B,› 95 mmHg (98 cases, 79.67%). Was used to measures of central tendency and dispersion, T-test and Pearson correlation coefficient (r).
Results: Blood pressure mean (mmHg) initial vs final of all patients was similar (114.64 ± 4.54 vs 103.88 ± 10.65, p = 1.46) but not the medial blood group A vs B (89.16 ± 4.54 vs 107.63 ± 8.22, p = 0.05). Endogenous creatinine clearance (mL/min/1.73 m2 SC) of the total was similar (101.88 ± 28.48 vs 98.73 ± 29.96, p = 0.40) in group A increased by 2.5 (p = 0.71) and decreased in group B 5.69 (p = 0.0056). R of the total income to the intensive care unit was 0.11 and the birth of 0.06, 0.0033 in group A and -0.44 and 0.13 in group B and 0.16, respectively.
Conclusion: The satisfactory control of blood pressure was achieved in 20.33% of cases. The correlation between blood pressure mean and endogenous creatinine clearance was very low.
