Summary
This trial aims to see if injecting a local anesthetic (1 percent lidocaine) near the cervix can reduce pain during the insertion of intrauterine devices (IUDs). Patients will
Who is the study for?
The PRICE Trial is for individuals seeking to have an intrauterine device (IUD) inserted for birth control. Participants must be willing to rate their pain during the procedure. There are no specific inclusion or exclusion criteria provided, suggesting that anyone presenting for IUD placement may be offered participation.
What is being tested?
This trial tests if a local anesthetic (1% lidocaine injection at the cervicovaginal junction) reduces pain during IUD insertion compared to a placebo saline injection or no injection at all. Patients will be randomly assigned to one of these three groups and asked about their pain experience afterward.
What are the potential side effects?
Potential side effects could include discomfort from the injections themselves, possible allergic reactions to lidocaine, and typical side effects associated with IUD insertion like cramping or bleeding.

Placebo Group
Group I: 1% Lidocaine Paracervical BlockExperimental Treatment1 Intervention
A 22-gauge spinal needle will be loaded with 10 mL of 1% lidocaine with epinephrine.
The injection will be instilled slowly over 60 seconds into the cervicovaginal junction in two equal areas at 4 and 10 o'clock. The injection is continuous from superficial to deep (3 cm).
Group II: Capped Needle ControlActive Control1 Intervention
A capped needle will gently be tapped on the cervicovaginal junction at two areas at 4 and 10 o'clock.
Group III: Normal Saline Paracervical InjectionPlacebo Group1 Intervention
A 22-gauge spinal needle will be loaded with 10 mL of normal saline. The injection will be instilled slowly over 60 seconds into the cervicovaginal junction in two equal areas at 4 and 10 o'clock. The injection is continuous from superficial to deep (3 cm).
