Effects of chlorhexidine-coated intrauterine device on the bacteriology of the uterine cavity

Abstract

Twenty-nine women, aged 31-53 years, scheduled for an abdominal hysterectomy, participated in this study. The patients were divided into three groups. The first received a Multiload MLCu250 intrauterine device (IUD); the second group received a chlorhexidine acetate medicated Multiload MLCu250 IUD; the third group acted as a control group receiving no IUD. Bacteriological cultures of the vagina and ectocervix were taken prior to insertion of the IUD. At hysterectomy, some 18 hours later, specimens were taken from the cervical canal, uterine cavity, and the device itself, for culture of anaerobic and aerobic organisms using a standardized previously validated technique. In three of the nine control patients, organisms were cultured from the uterine cavity. There were no differences between the bacteriological results of the two groups with medicated and non-medicated devices, with regard to the cultures from the cervical canal, uterine cavity or the devices themselves. Nor was there any difference between the control and the IUD group.
