Anaphylactoid reaction to infusion of polygelatin (Haemaccel). A study in pregnant women.

A series of allergic reactions to infusion of polygelatin (Haemaccel) in six pregnant women is reported. These women and a control group of five pregnant women were studied with analysis of complement, ELISA and skin tests. No differences were found between the groups in the factors studied. It is concluded that the reactions to polygelatin were caused through direct liberation of histamine, that is, an anaphylactoid reaction.
