An Observational Study on the Application of the Second-generation Radiopaque Subcutaneous Implant.

To analyze the effect, side effects, and satisfaction of the second-generation radiopaque subcutaneous implant, providing healthcare workers a basis for propaganda and guidance. Methods: A total of 214 cases of healthy women with birth control requirements from August 2016 to June 2018 received ray subcutaneous implants. Quantitative surveys were administered 10 days, 3 months, 12 months, and 24 months later. All cases were implanted successfully. The number of effective cases was 211, with 3 cases lost to follow-up. The pregnancy rate of 211 subjects during receiving implant was 0. Changes in bleeding patterns (130 cases, 61.61%) remained the most common side effect event. The rate of withdrawal was 96.21% in the first year and 66.35% in the second year. There were 48 cases (67.61%) who withdrew due to the change of bleeding pattern. All participants with bleeding patterns were divided into the withdrawal group and the non-withdrawal group, and there were significant differences in educational background, number of pregnancies, abortion, and income between the two groups. According to the satisfaction survey, 37 (17.54%) were very satisfied, 109 (51.66%) were satisfied. The contraceptive rate of radiopaque subcutaneous implantation was very high, and there were no serious side effects while receiving an implant. The change of bleeding pattern was the main reason for withdrawal, which was related to educational background, number of pregnancies, history of abortion, and economic conditions. Pre-implantation consultation and post-implantation management should be strengthened.
