A comparative study of Lippes loop and Delta loop intrauterine devices in early postpartum.
Two IUDs (Delta loop, Lippes loop D) were randomly inserted in 260 postpartum women within 2-36 hours after delivery by uterine-packing forceps. The Delta loop was designed with the intention of lowering the expulsion rate compared with the standard Lippes loop. The analysis of the data indicated that the expulsion rate of the Delta loop was as high as the Lippes loop D at the one-month follow-up (Delta loop 24.1%, Lippes loop 23.9%). The comparison of other pertinent event rates also showed no significant differences.
