  • Title: Hypertension in pregnancy.
    Author: Fisher KA.
    Journal: Prim Care; 1983 Mar; 10(1):115-24. PubMed ID: 6553934.
    Abstract:
    Blood pressure; extracellular fluid volume; renal plasma flow; glomerular filtration rate; plasma concentrations of renin, angiotensin, aldosterone, desoxycorticosterone, and prostaglandins; responses to infused angiotensin; and many other factors are altered during normal and hypertensive gestation. The diagnosis of the exact disease process responsible for hypertension in pregnancy in an individual patient is extremely difficult if based solely on clinical criteria. The American College of Obstetricians and Gynecologists has suggested the following clinical classifications: (1) preeclampsia-eclampsia, (2) chronic hypertension of whatever cause, (3) chronic hypertension with superimposed preeclampsia, and (4) late or transient hypertension. The three broad categories of renal disease responsible for these clinical syndromes are: (1) preeclampsia-eclampsia, (2) hypertensive changes, and (3) various primary renal diseases. Controversy abounds regarding the aggressiveness of therapy in this syndrome. We prefer a middle-of-the-road approach, bringing blood pressure down to the range of 95 to 100 mm Hg. Hydralazine and Aldomet are the usual drugs of choice. Any intervening nervous system hyperexcitability suggests impending eclampsia and should be immediately treated with magnesium sulfate. The long-term prognosis for the mother with pure preeclampsia appears to be excellent. Most infants born of hypertensive gestations are small for date, with a prognosis that is also affected by the underlying disease of the mother.
