A comparative study of two techniques used in immediate postplacental insertion (IPPI) of the Copper T-380A IUD in Shanghai, People's Republic of China

Contraception. 1996 Jul;54(1):33-8. doi: 10.1016/0010-7824(96)00117-5.


Chinese women in Shanghai who delivered vaginally and who chose to use an IUD for contraception received a Copper T-380A IUD inserted vaginally within 10 minutes after delivery of the placenta (i.e., immediate postplacental insertion, IPPI). Among them, 97.7% were primipara. The women were randomly divided into two groups: IUD inserted by hand and IUD via ring forceps. The follow-up rate of six months was 95.2%. Using Tietze's life table method and log rank test, the expulsion and other discontinuation rates were compared at three and six months postinsertion between these two different insertion techniques. Expulsions were the main reason for discontinuation. The six-month gross cumulative expulsion rates were 13.3 and 12.7 per 100 women in the hand-insertion group and ring forceps-insertion group, respectively. Discontinuation rates for medical removals (bleeding/pain) were 2.1 and 1.0 in these two groups, respectively. Neither of the differences was statistically significant (p > 0.05). No uterine perforation, infection or pregnancy occurred. The results suggest that these two different insertion techniques do not significantly affect discontinuation rates in vaginal IPPI using the TCu 380A, and the TCu 380A appears to be suitable for postpartum insertion in Chinese women. Other relevant issues, such as breastfeeding and IUD placement in uterine cavity, are also analyzed and discussed in this report.

PIP: During October 1993 to October 1994, in Shanghai, China, 910 women who delivered vaginally at 13 medical centers and requested IUD contraception were randomly allocated to the group in which the TCu 380A was inserted by hand (470) or to the group in which it was inserted by ring forceps (440) within 10 minutes after delivery of the placenta. This was the first birth for 97.7% of the women. The 6-month follow-up rate was 95.2%. 3-month and 6-month expulsion rates as well as rates for medical and non-medical removals between the two insertion techniques were not significantly different (p 0.05). For example, the 6-month gross cumulative expulsion rate was 13.3% for the hand-insertion group and 12.7% for the ring forceps-insertion group. The discontinuation rate for medical removals (e.g., bleeding, pain) was 2.1% for the hand-insertion group and 1% for the ring forceps-insertion group. The IUD expulsion rate was higher in non-breast feeding women than in breast-feeding women (22.4% vs. 11.9%; p 0.05). No woman in either group suffered from uterine perforation or an infection. No woman conceived. In conclusion, the two different IUD insertion techniques do not have a significant influence on discontinuation rates in vaginal immediate postplacental insertion using the TCu 380A.
