Postpartum hypertension including persistent and recurrent hypertension could significantly affect maternal morbidity in preeclampsia. Data on the postpartum management of women with preeclampsia is limited. The objective of this study was to investigate the details of women experiencing persistent postpartum hypertension (PerPPH) or developing recurrent postpartum hypertension (RecPPH) after birth and whether the treatment with anti-hypertensive drugs could shorten the hospital stay. We also compared the clinical parameters in women who developed RecPPH and who did not. Data on 188 preeclamptic women, including the severity or time of onset, duration of hospital admission postpartum, and blood pressure during the admission were collected and analyzed. Overall, 30% of preeclamptic women developed RecPPH on day 1, 13% on day 3, and 12% on day 5 after birth. Women with severe preeclampsia or early onset preeclampsia are more likely to develop RecPPH, compared to women with mild or late onset preeclampsia. The overall time in days before discharge was not different between women with normal blood pressure and women with abnormal blood pressure 1 h after birth, regardless of the severity or gestation of onset. However, women with severe or early onset preeclampsia stayed longer in the hospital, compared to women with mild or late onset preeclampsia. In addition, women with severe or early onset preeclampsia or early delivery increased risk of developing RecPPH. In conclusion, we demonstrate that RecPPH became apparent on day 1 after delivery, and hence close monitoring of blood pressure even if initially seemingly normal after birth is important.
