Coagulation changes during second-trimester abortion induced by intra-amniotic prostaglandin E2 and hypertonic solutions.
The coagulation system was studied in twenty-seven patients undergoing second-trimester abortion induced by intra-amniotic prostaglandin (P.G.) E2 alone and in combination with a hypertonic solution of urea or glucose. Changes consistent with intravascular coagulation, namely a rise in fibrin degradation products and a fall in plasma-fibrinogen and platelet-count, were observed in those patients treated using P.G.E2 with hypertonic urea. Similar but less pronounced changes were found in the group treated using P.G.E2 with hypertonic glucose. In patients treated with P.G.E2 alone no changes suggestive of intravascular coagulation were detected. One patient treated using P.G.E2 with hypertonic urea who did not abort for 26 hours demonstrated changes indicative of a pronounced degree of disseminated intravascular coagulation. These findings show that when abortion is induced using P.G.E2 and a hypertonic solution, particularly hypertonic urea, disseminated intravascular coagulation can occur as a result of a hypertonic agent being used.
