Objective: To compare maternal and perinatal outcome with the use of either
intravenous ketanserin or dihydralazine in treatment of women with preecla
mpsia.
Methods: The records from January 1989 to January 1997 of all patients rece
iving intravenous ketanserin or dihydralazine as first line antihypertensiv
e therapy were reviewed and standardized data forms were completed. 315 cha
rts of patients were identified and evaluated for effects on blood pressure
. laboratory parameters, maternal and perinatal outcome.
Results: During the study interval 169 patients received ketanserin and 146
dihydralazine. Significantly fewer antepartum (27% versus 38%, p = 0.04) a
nd postpartum (25% versus 39%, p = 0.01) maternal complications were noted
in patients receiving ketanserin. Occurrence of HELLP syndrome was signific
antly lower among patients who received ketanserin (20%) than among those w
ho received dihydralazine (40%, p = 0.0001). Side-effects were reported wit
h significantly higher frequency in patients receiving dihydralazine (60%)
as compared to those receiving ketanserin (17%,p < 0.0001). Perinatal outco
me was comparable, however, umbilical cord arterial pH values (mean <plus/m
inus> SD) were higher with ketanserin compared to dihydralazine (7.25 +/- 0
.07 vs 7.23 +/- 0.09,p = 0.038). The incidence of placental abruption was h
igher in patients receiving dihydralazine (5.5%) versus those receiving ket
anserin (0.6%, p = 0.014).
Conclusion: Ketanserin appears to be a better option than dihydralazine for
treatment of severe preeclampsia since fewer maternal complications and si
de-effects were observed in patients receiving ketanserin.
