Electroencephalographic changes following intraamniotic prostaglandin F2 alpha administration for therapeutic...

Electroencephalograms were obtained on 43 patients undergoing therapeutic second trimester abortion using intraamniotic prostaglandin F2alpha. Recordings were made before and 4 hours after prostaglandin administration, as well as 4 hours after the abortion. At 4 hours after prostaglandin administration, 30% of the women had abnormal tracings, while 50% of the women had abnormal recordings 4 hours postabortion. Although the changes consisted primarily of mild generalized or lateralized slowing, 4 patients developed paroxysmal activity not initially present. This finding would seem to suggest a potential relationship between PGF2alpha administration and clinical seizures.
