The shield intra-uterine device: a preliminary clinical appraisal.


 The Dalkon shield was fitted to 30 patients attending the Hammersmith Hospital, London, who were followed for at least 9 months. 1 patient was pregnant at time of insertion, 1 patient became pregnant at 7 months, and another at 9 months. There were no expulsions and no removals. No uterine perforations occurred. Duration of menstrual flow was slightly longer and blood loss was slightly heavier. 23 of the 30 patients reported that they felt they had complete and satisfactory contraceptive cover.
