【 摘 要 】

Pre-eclampsia is an important cause of mortality and morbidity in parturients with varied presentations and controversial pathophysiology. The central pathology is a profound vasoconstriction in the vasculature leading to volume contraction and placental hypoperfusion. The management mainly involves a multi-disciplinary approach with the anesthesiologist playing a significant role for a positive outcome. Anesthesia for such parturients remains a challenge and starts with provision of labor analgesia which should be offered to all preeclamptic parturients. The neuraxial techniques of analgesia are most favourable for adequate pain relief and if contraindicated, intravenous PCA technique with the use of opioids should be used. Recent studies show favourable maternal and fetal outcomes with the use of patient controlled epidural analgesia technique with the combination of lower concentrations of local anesthetics with opioids. Regional anesthesia should be preferred in these parturients for cesarean section if not contraindicated. If general anesthesia is indicated, the techniques should be modified to prevent any stress response. A careful and prompt use of oxytocics should be done in all cases as the incidence of postpartum hemorrhage is high in these parturients.
