Objective: To evaluate the impact of a copper-containing intrauterine contraceptive device (IUCD) and the levonorgestrel-releasing intrauterine system (IUS) on puerperal and menstrual bleeding when fitted intraoperatively during scheduled elective cesarean.
Methods: Participants were allocated to 3 groups: cesarean with no device inserted; IUCD inserted during cesarean; and IUS inserted during cesarean.
Results: There was significantly shorter and lighter puerperium in the IUS group (20.2 ± 7.7 days and 3.1 ± 1.6 pads/day) than in the IUCD (33.4 ± 9.5 days and 4.9 ± 2.4 pads/day) and the control (27.0 ± 11.4 days and 4.9 ± 2.3 pads/day) groups (P<0.012 and P<0.0001, respectively). At the end of puerperium, mean duration of amenorrhea was significantly longer in the IUS group than in the IUCD and control groups (P<0.0001). Menstrual periods were longer and heavier in the IUCD group than in the control group but the difference was not significant (P>0.07). In the IUS group, menstrual periods were significantly shorter and lighter than in the other groups (P<0.0001).
Conclusion: Intrauterine system fitting at the time of elective cesarean is associated with significant reductions in the duration and amount of puerperal blood loss, as well as a high incidence of amenorrhea and lighter periods thereafter.
