“…1,2) Although once widely believed to reflect the effects of vasospasm and thrombosis, 3,4) neurologic deficits in patients with hypertensive encephalopathy are now believed to be most commonly caused by vasogenic edema attributable to fluid that escapes from the intravascular compartment into the interstitium due to impaired autoregulation. 1,2,5,6) The clinical and radiographic signs in patients with eclampsia might be related to acutely elevated systemic blood pressure (BP), which impairs the autoregulation of cerebral blood flow due to hypertensive encephalopathy. Our previous study demonstrated that the increase in BP, as well as the oscillation of BP just before eclampsia onset, might greatly influence the onset of eclampsia.…”

Aim: It has been reported that eclampsia might be caused by vasogenic edema from impaired autoregulation of cerebral blood flow, potentially due to elevated systemic blood pressure (BP). This study retrospectively investigated changes in systemic BP around eclampsia onset. Methods: Eight women with eclampsia were enrolled. Three received antihypertensive drugs. Four had labor pains. Systolic and diastolic BP and heart rate were evaluated. Mean arterial pressure (MAP) and changes in BP (ΔBP) just before and after eclampsia onset were calculated. Results: Systemic BP markedly increased just before eclampsia onset, then decreased to lower than before onset. The ΔBP1 (each BP just before eclampsia onset − mean BP) was 21 ± 9 mmHg (21 ± 11%), and the ΔBP2 (each BP just after eclampsia onset − BP just before eclampsia onset) was − 40 ± 18 mmHg ( − 31 ± 12%) in MAP. The heart rate rapidly increased just after onset (75 ± 8 vs. 128 ± 6 bpm). Fetal cardiac monitoring showed prolonged deceleration in all pregnant patients. Conclusions: It was suggested that both marked increase and decrease in BP around the onset of eclampsia might cause strong damage in not only maternal but also fetal blood circulation.

“…La mortalité maternelle liée à l'éclampsie est aujourd'hui faible dans les pays européens (entre 0 et 1,8 %) grâce à une prise en charge rapide et adaptée [6,32], mais elle varie entre 14 et 15,6 % dans les pays en voie de développement [2][3][4][5][6][7][8][9][10][11][12][13]. Une série marocaine récemment publiée sur 342 cas d'éclampsie retrouvait une mortalité de 6,7 %.…”

“…L'éclampsie est responsable de 50 000 décès par an dans le monde [13]. Les complications maternelles sont significativement plus fréquentes dans les éclampsies du péripartum (HELLP syndrome, hématome rétroplacentaire [HRP], coagulation intravasculaire disséminée [CIVD], insuffisance rénale aiguë) [2,6,12]. La mortalité périnatale varie de 5,6 à 11,8 % et est essentiellement liée aux complications de la prématurité induite, aux HRP et aux retards de croissance in utero (RCIU) [5,9,14].…”

Aim: It was reported that eclampsia might be caused by vasogenic edema from broken autoregulation in cerebral blood flow, potentially due to elevated systemic blood pressure (BP). This study retrospectively investigated the severity of BP elevation and oscillation amplitude of systemic BP just before eclampsia onset. Methods: Five eclamptic and 4 non-eclamptic women with complications of preeclampsia were enrolled. Three eclamptic and 4 non-eclamptic women with severe hypertension received antihypertensive drugs. Systolic and diastolic BPs, mean arterial pressure (MAP), and oscillation amplitude of BP (ΔBP) before eclampsia onset were evaluated. Results: Maximum MAPs in eclamptic women did not significantly differ from that of non-eclamptic women (130 ± 17 mmHg vs. 116 ± 8 mmHg, respectively). The systolic and diastolic ΔBP in eclamptic women were higher than that in non-eclamptic women (45 ± 15 mmHg vs. 16 ± 6 mmHg, P = 0.03, and 25 ± 6 mmHg vs. 9 ± 2 mmHg, P = 0.004, respectively). Conclusions:Our results indicate that a large ΔBP could influence eclampsia onset.
