ATYPICAL PRESENTATION OF PREECLAMPSIA IN HIGH-ORDER MULTIFETAL GESTATIONS

Objective: To describe our experience with preeclampsia in high-order multifetal gestations. Methods: Records for all triplet and quadruplet pregnancies delivered after 24 weeks' gestation from January 1988 thr ough Tune 1994 were reviewed. All patients were treated with bed rest from 20 weeks' gestation onward and received corticosteroids weekly be ginning at 24 weeks. Tocolytics were used as needed. Results: Twenty-o ne triplet and eight quadruplet pregnancies were studied. The mean ges tational age at delivery was 32.3 and 27.9 weeks, and mean birth weigh ts were 1547 and 1028 g, respectively. Seventeen of 29 patients develo ped preeclampsia, 14 of the 21 triplet mothers and three of the eight quadruplet mothers. Among 16 patients who were delivered for preeclamp sia, only eight had blood pressure (BP) elevation before delivery, whe reas ten had epigastric pain, visual disturbances and/or headache; nin e had elevated liver enzyme levels; and seven had low platelet counts. Only three patients had proteinuria, and only six had edema. Five wom en developed the syndrome of hemolysis, elevated liver enzymes, and lo w platelets postpartum, all of whom had normal BP before delivery. Two patients developed preeclampsia after delivery. A total of 95 infants were delivered, all by cesarean, of whom 93 (98%) survived. Conclusio n: Preeclampsia is common in high-order multifetal gestations and ofte n presents in an atypical manner. Hypertension is not always the prese nting sign, and symptoms consistent with severe preeclampsia and abnor mal laboratory values predominate.
