ETONOGESTREL IMPLANT (IMPLANON);

FREQUENCY OF ADVERSE EFFECTS CAUSED BY IMPLANTATION OF SINGLEROD ETONOGESTREL IMPLANT (IMPLANON) IN FEMALES SEEKING BIRTH SPACING AFTER DELIVERY OF PREVIOUS PREGNANCY

Abstract

Objective: To assess the frequency of adverse effects caused by implantation
of single-rod Etonogestrel implant (Implanon) in females seeking birth spacing after delivery
of previous pregnancy. Study Design: Descriptive case series. Setting: Unit V, Department
of Obstetrics & Gynecology, and Lady Aitcheson Hospital Lahore. Period: One year from
01/04/2015 to 31/03/2016. Materials & methods: A total of 130 women fulfilling our selection
criteria were selected. The ENG implant is a single (coaxial) rod made up of an ethylene vinyl
acetate (EVA) copolymer core (40% EVA) containing 68mg ENG, surrounded by a 60mm skin
of EVA copolymer (100% EVA). The implant was inserted during days 1 to 5 of spontaneous
menses and left in place and adverse effects (abnormal vaginal bleeding or pregnancy)
was measured (as per operational definition) for a period of 3 months. All this information
was recorded in proforma (attached). Data was entered and analyzed in SPSS version 17.0.
Results: The mean age of females was 29.08 ± 4.027 years with minimum and maximum
age of 20 and 40 years. Adverse events were seen in 36(27.7%) of the females while other
94(72.3%) did not have any adverse effect of implantation of single-rod Etonogestrel implant
(Implanon) in females seeking birth spacing after delivery of previous pregnancy. Abnormal
vaginal bleeding was reported by 19(14.6%) and pregnancy was occurred in 17(13.1%) of the
females. Conclusion: According to the findings of this study we found less adverse effects like
abnormal vaginal bleeding in 19(14.6%) females and pregnancy was occurred in 17(13.1%)
of the females. Hence we conclude Implanon is an effective mode of contraception in females
seeking birth spacing and can be adopted in females seeking family planning.
