A randomized comparative trial of the Lippes Loop D, Gravigard and TCu 220C IUDs.

This randomized prospective trial compared the use-effectiveness and pregnancy rates in 3 IUDs following immediate postabortal insertion in 199 women over 3107 months of use. At 24 months the Gravgard (Cu 7) was not significantly different from either of the other 2 devices. However, the Lippes Loop D when compared with the TCu 220C had a higher expulsion rate (P less than 0.05) and a higher use-related termination rate (P less than 0.001). Further details of accidental pregnancies, removal for incomplete abortion or pelvic inflammatory disease and within 48 hours after insertion are presented.

A multicenter randomized comparative investigation of ML Cu250, TCu-220C and Cu7 IUDs.

The final analysis of 1725 interval insertions of the 3 IUDs is presented. The earlier observations were confirmed at: at 24 months, no significant differences were found between the TCu-220C and ML Cu250 IUDs though the TCu-220C had a lower gross pregnancy rate (2.0 versus 2.9) and the ML Cu250 had a lower expulsion rate (2.3 versus 4.1). Expulsions were more common with the Cu7 when compared to the ML Cu250 (p 0.001) and T-220C (p 0.01); pregnancy rates were also higher with p values of 0.05 and 0.01 respectively. Other use-related terminations were not significantly different among the 3 IUDs and continuation rates at 24 months were: Cu7, 69, TCu-220C, 73, and ML Cu250, 74.

Cross of Lorraine and Cross of Caravaca: new IUD's with low expulsion rates.

The Cross of Caravaca and Cross of Lorraine IUDs with double horizontal bar design were developed in an attempt to reduce expulsion and removal rates for pain and bleeding encountered with other IUDs. The devices were manufactured in radio-opaque plastic bearing copper wire or sleeves on the top arm. The Cross of Lorraine has the upper arm shorter than the lower arm whereas in the Cross of Caravaca the shorter is the lower arm. 748 women had insertion of the Cross of Caravaca and 412 had insertion of the Cross of Lorraine. For the Cross of Caravaca 486 women completed 1 year of use, 392 completed 2 years and 310 completed 3 years. For the Cross of Lorraine, 268 women completed the 1st year, 205 the 2nd, and 150 women completed 3 years of use. The combined number of observed months of use for the 2 devices at the end of 3 years was 24,963. Accidental pregnancy rates at the end of 3 years were 1.13% for Caravaca and 3.48% for Lorraine. Expulsion rates at the end of 3 years were nil for the Cross of Lorraine and 1.16% for the Cross of Caravaca. Pain and bleeding were the most common causes of termination for medical reasons, bleeding accounting for termination in 1.66% of Lorraine users at the end of 3 years of use and 2.75% of Caravaca users. Pain accounted for termination in 3.14% of Caravaca users and 2.02% of Lorraine users. Incidence of infection was 0.42% and nil for Caravaca and Lorraine users respectively. Total discontinuation rates at the end of 3 years were 25.39% for Caravaca and 16.67% for Lorraine.
