NECOCHEA (Cuatro Vientos) - The director of Primary Health Care, Dr. Maximiliano Delfino, reported that on Tuesday the first subdermal implant was placed in the San Martín Neighborhood Health Center (200 homes).The Municipality thus initiated a contraceptive method that is being tested in our country and that is aimed at young women between 15 and 19 years old, in order to avoid unwanted teenage pregnancies.The official acknowledged that "it is a new method for us (it is placed in the arm), but it has been used in the world for years." "You have to avoid pregnancy when you are studying because that is when school dropout occurs" , he pointed.The official also trained this Tuesday, September 1, the team of the aforementioned Health Center, so that he can continue to place this contraceptive method on a daily basis, an operation that he will carry out in all the CAPS of the district for free.For his part, Dr. Juan Pedro Arabarco added that "we are targeting family planning as a primary objective, with this method that reaches users free of charge."Vanesa Ledesma , a local nurse, highlighted the importance of this method, since "the young people out there fail with the proper use of the pill", while recalling that "it lasts three years, it is easily removed and another one is placed. ”.Thus, low-income adolescents in the district have begun to be "sterilized" for periods of three years.The information in this regard will be provided in the different health centers of the city.Subdermal contraceptive, transdermal implant, subcutaneous implant, also known as pellet or pellet, is a hormonal contraceptive method made up of a small rod that is placed under the skin of the woman's arm, offering contraceptive protection for three to five years.Once its effectiveness has been exhausted, the doctor must remove the implant.The development of subdermal contraceptives began in 1967, when the American Sheldon Segal and the Chilean Horacio Croxatto1 proposed the use of subdermal capsules of the polymer polydimethylsiloxane (Silastic®) for the slow and prolonged diffusion of the active contraceptive principle -it was proposed that they be steroidal (lipophilic) hormones.In the first trials -first in animals and then in humans- chlormadinone acetate (ruled out due to its association with breast cancer), megestrol acetate (ruled out due to its side effects and low effectiveness), norethindrone, norgestrinone and levonorgestrel, with failures and successes.In 1975, the Population Council, in coordination with the International Contraceptive Research Committee, selected levonorgestrel with a progestogen for use in the development of subdermal contraceptive implants due to its efficacy and few side effects.The combination of silastic and levonorgestrel is what the Population Council used to develop and patent the norplant and norplant-2 (Jadelle) implant systems.Its efficiency is around 99%.As its placement is done for a long period of time, it reduces the risk of forgetting that other contraceptive methods such as the pill or the contraceptive patch do have.Other sources indicate that its effectiveness is 95% depending on its correct use.Advantages and disadvantages On the one hand, this type of contraceptive has a series of benefits that are: High contraceptive effectiveness (Very high effectiveness) - 99%.Excellent option when there is a contraindication for the use of estrogens.Excellent choice during lactation.Low cost of the method in the medium term.No cumulative effect of the medication: when the implants are removed, all medication is eliminated in a matter of a few days (about 100 hours, depending on the half-life of the hormonal component).Quick return to fertility.Amenorrhea (absence of menstruation): prevents or helps correct anemia.Continuous effectiveness.They regularize menstrual cycles and serve to treat painful periods.7 At the same time, the inconveniences that their use can cause should be mentioned. Alteration of the regular pattern of menstrual bleeding 35%.Regular genital bleeding.Weight gain, acne, fluid retention (edema), depression: less than 10%.High initial cost.Local complications at the insertion site (skin incisions, local anesthetics, bruising, infection), difficulty in removing implants, occasional loss or impossibility of removing an implant (almost exclusively with Norplant).Decreased effectiveness in obese patients (body mass index greater than 30).ovarian cysts.Medical unit for placement and removal of the device.Some of these devices cannot be seen on x-rays (Rx) so if they are "lost" they are difficult to locate (the sonogram is more helpful but requires experience).The following symptoms require immediate review: late period (greater than 6 weeks), after several regular cycles (could indicate pregnancy), severe pain in the lower abdomen (could be a symptom of ectopic pregnancy), excessive bleeding or prolonged (more than 8 days or more than twice normal), pus or bleeding at the insertion site, expulsion of one or both of the implant rods, repeated very painful headache or blurred vision.® Copyright 2015 Cuatro Vientos Find us on Facebook: facebook.com/diario4v Follow us on Twitter: @diario4v Contact us: info@diario4v.com
