Intrauterine device (IUD) are the 20 time more effective forms of reversible contraceptive methods than pills. But large number of poupulation of this group uses contraceptive pills rather than IUD beacause of its fear of pain. The results of the present study states that 1% Lidocaine successfully reduce the pain during IUD insertion.

To determine the impact of a 1% Lidocaine paracervical nerve block on pain during intrauterine device (IUD) insertion than with a sham block within adolescents and young women.

Adolescents and young women who were not currently pregnant, nulliparous, and known English inserted with the 13.5-mg Levonorgestrel IUD at three three family planning clinics of Philadelphia. Patients were divided into two groups and obtained either 10-mL 1% Lidocaine paracervical block or a sham block. Blinding was only done with the patients. Pain after IUD insertion was taken as the primary outcome. Applying two-sided t-test and presuming a 20-mm difference in visual analogue scale scores, an α of 0.05, 90% power, and an SD of 28 mm, a sample of 43 participants per group was determined.

A total of 95 participants were selected. Seventy-nine per cent of the patients previously used the contraceptives. Lidocaine block group exhibited 30.0 and the sham block group presented 71.5 median visual analogue scale score after IUD insertion.

A 10-mL 1% Lidocaine paracervical nerve block decreases the pain during IUD insertion within adolescents and young females than the sham block with pressure on the vaginal epithelium.
