Non-ionic contrast media cause fewer acute reactions than ionic media but there is insufficient data on mortality rates. An international reference centre is suggested for histological assessment of fatal reactions. Risk factors, delayed reactions, renal, neural, haemic and other miscellaneous reactions are briefly discussed.

The incidence of abdominal pain during hysterosalpingography was assessed from replies to postal questionnaires completed by 42 patients receiving Diaginol Viscous and 23 patients receiving Dimer X: the questionnaires were analysed using a double-blind technique. In the Diaginol Viscous group, 58.5% of patients experienced moderate or severe pain during the injection as compared with an incidence of only 19% in the group receiving Dimer X. In three of tha patients receiving Diaginol Viscous, there was brief loss of consciousness. Radiographic quality was satisfactory with both contrast media. After effects of hysterosalpingography were relatively common and included: lower abdominal pain; vaginal bleeding; temporary difficulty in walking; menstrual disturbances in subsequent periods. No correlation could be demonstrated between the type of medium used and the incidence of these after effects.
