Preeclampsia, hypertension, and a possible treatment for preeclampsia.

The pregnancy-specific disorder preeclampsia is believed to affect 2-8% of pregnancies worldwide. The only known cure is delivery of the fetus and placenta. This brief communication cites evidence that might suggest a moderately effective treatment for preeclampsia. The therapy consists of having the gravida with preeclampsia stay in a room provided with FACE (Free Air Carbon-dioxide Enrichment). No containment (such as in greenhouses) is required with FACE systems. Evidence is cited which suggests that the therapy might reduce the incidence of preeclampsia by perhaps 10-30% without much harm to the fetus.
