Eclampsia occurring more than 48 hours postpartum has been observed in an unusual number of patients. From August 1977 to November 1982 at E. H. Crump Women's Hospital and Perinatal Center (Memphis), there were 132 documented cases of eclampsia, of which 36 (27%) occurred postpartum. Seventeen (47%) of these occurred more than 48 hours postpartum. Preeclampsia was diagnosed before the onset of convulsions in 12 patients, all of whom received intravenous magnesium sulfate postpartum. The mean duration of postdelivery magnesium sulfate therapy was 32 hours (range 24 to 72 hours). Headaches and visual disturbances were reported by all 17 patients before onset of convulsions. Physical and laboratory findings immediately after the convulsions were consistent with eclampsia. Treatment consisted primarily of intravenous magnesium sulfate. Neurologic consultation was obtained to rule out a neurologic disorder, and metabolic studies were also done. Electroencephalograms were done on 15 patients; eight of them showed patterns consistent with encephalopathy.
产后48小时以上发生子痫的患者数量异常之多。1977年8月至1982年11月期间，在孟菲斯的E.H.克伦普妇女医院和围产期中心，有132例记录在案的子痫病例，其中36例（27%）发生在产后。其中17例（47%）发生在产后48小时以上。12例患者在惊厥发作前被诊断为子痫前期，所有患者产后均接受静脉注射硫酸镁治疗。产后硫酸镁治疗的平均持续时间为32小时（范围为24至72小时）。所有17例患者在惊厥发作前均报告有头痛和视觉障碍。惊厥发作后立即进行的体格检查和实验室检查结果与子痫相符。治疗主要包括静脉注射硫酸镁。寻求神经科会诊以排除神经系统疾病，并进行了代谢研究。15例患者进行了脑电图检查；其中8例显示出与脑病相符的脑电图模式。
