Preeclampsia remains a major cause of worldwide pregnancy related maternal and neonatal mortality and morbidity, it accounts for more than 50,000 maternal deaths each year. The World Health Organization estimates that at least one woman dies every 7 minutes from a complication of preeclampsia. It is the main cause of maternal death in Mexico and Latin America. Standarized assessment and surveillance of women with preeclampsia is associated with reduced maternal risk. Standarized sequence was established to search for practice guidelines from the clinical questions raised on diagnosis and treatment of preeclampsia-eclampsia. The working group selected clinical practice guidelines found in the Cochrane Library, Medline and PubMed. The results were expressed as levels of evidences and grade of recommendation. Evidence suggests, that treatment of severe hypertension, seizures prophylaxis with magnesium sulfate, and management by experienced health-care professionals will improve maternal, fetal and neonatal outcomes. Treatment remains supportive with pregnancy termination being the only definitive cure.
