RESUMO
PURPOSE: Intrauterine device (IUD) is one the most effective contraceptive methods with reversible long-term effects. However, the major drawback of IUD use is pain perception during the insertion of the device. The aim of this study is to investigate the effects of bilateral LI4 acupuncture, administered before IUD insertion, on pain perception. METHODS: This is a prospective randomized controlled study. It was held in Community Health Center in Nigde, Turkiye. Individuals enrolled in the study were randomized into the acupuncture group and non-intervention group. Acupuncture group received bilateral LI4 acupuncture prior to IUD insertion while others received no interventions. After IUD insertion, 10 cm visual analog scale (VAS) score was evaluated at 3rd minute and at 10th minute. Health care provider performing the IUD insertion and VAS evaluation was blind to randomization. RESULTS: In total 72 participants were included in the study. The VAS scores were significantly lower in the acupuncture group both at 3rd minute and at 10th minute (1.93 ± 1.68; 3.81 ± 1.95; p < 0.001 and 0.53 ± 0.84; 1.64 ± 1.10; p < 0.001 respectively). Linear regression analysis showed that acupuncture was a significant predictor for lowering VAS both at 3rd minutes and 10th minutes following IUD insertion (p < 0.001). CONCLUSION: This is the first randomized controlled clinical study investigating the effects of acupuncture on pain control during IUD insertion. The results demonstrated that bilateral LI4 acupuncture provides significant pain relief at both cervical and fundal components. Acupuncture prior to IUD insertion is a significant predictor of lowering overall VAS scores of individuals. TRIAL REGISTRATION: NCT04963582.
