The single-rod Implantable contraceptive method, called 'Implanon', has been introduced for use in Thailand since the 1990s. The outstanding attribute was that it requires only a few minutes for insertion and removal as it has only one capsule. The single-rod implant was used in women at Siriraj Hospital in 2006. The present study looked at characteristics of women, complications of insertion and removal, menstrual events that occurred to women during one year of use and reason for removal of the method.
This was a retrospective clinic based study. All women's record files were examined at Siriraj Hospital's Family Planning Clinic. There were 166 women enrolled to undergo this method, and only 89 women (54.6%) came back for the one-year follow-up visit. Women's accounts on irregularity of menses, complaints during method used and reason for discontinuation, pregnancy and body weight change were assessed.
Most women (68%) using the implant contraceptive method were 29 years of age with 74% of vocational or lower education. Their BMI was 22.66 +/- 4.06 Insertion time was about 1 minute with no difficulty or complication. Of those women, 40.4% of them considered having regular menstrual cycle and 30.3% had regular menstrual flow for a few months alternately with no menses for a few months. Prolonged menstrual bleeding was the most complaint in this group of women. Amenorrhoea was also reported. Vertigo had occurred to some women without reported medication. One woman asked for the removal of the method due to pain at the implanted site after 8 months of use. Removal time was around 2-3 minutes. There was no pregnancy that occurred in the course of one year of use.
Of 89 women using the implant contraceptive method, menstrual irregularity was the important issue that women complained about. However, the removal of the method in one woman was due to the pain at the implanted site. There was no difficulty or complications in insertion or removal of the implant. Close counseling about side effects of the method is emphasized during use to maintain long-term use or until completion of the duration of the device.
自20世纪90年代起，名为“依伴侬”的单棒式可植入避孕方法已在泰国投入使用。其突出特点是，由于只有一根胶囊，植入和取出仅需几分钟。2006年，素里拉杰医院的女性开始使用单棒式植入物。本研究观察了使用该方法女性的特征、植入和取出的并发症、使用一年期间女性发生的月经情况以及取出该方法的原因。
这是一项基于临床的回顾性研究。在素里拉杰医院计划生育诊所检查了所有女性的病历档案。共有166名女性登记采用该方法，只有89名女性（54.6%）回来进行一年的随访。评估了女性关于月经不规律、使用该方法期间的不适以及停药、怀孕和体重变化原因的描述。
使用植入式避孕方法的大多数女性（68%）年龄为29岁，74%为职业教育或以下学历。她们的体重指数为22.66±4.06。植入时间约为1分钟，无困难或并发症。在这些女性中，40.4%认为月经周期规律，30.3%月经持续数月规律，与数月闭经交替出现。经期延长是该组女性最常抱怨的问题。也有闭经的报告。一些女性出现眩晕，但未报告用药情况。一名女性在使用8个月后因植入部位疼痛要求取出该方法。取出时间约为2至3分钟。在使用一年期间未发生怀孕情况。
在89名使用植入式避孕方法的女性中，月经不规律是女性抱怨的重要问题。然而，一名女性取出该方法是因为植入部位疼痛。植入物的植入或取出没有困难或并发症。在使用期间强调对该方法副作用进行密切咨询，以维持长期使用或直至器械使用期限结束。
