Effectiveness of Intrauterine Anesthesia on Pain Management During IUD Insertion: A Meta-Analysis of Randomized Controlled Trials
Listen to this summary
The authors aimed to evaluate the effectiveness of intrauterine anesthesia (IUA) compared to normal saline infusion in reducing pain during intrauterine device (IUD) insertion. Their meta-analysis of six randomized controlled trials involving 651 women found that IUA significantly reduced pain during the procedure, particularly when lidocaine was used, although pain after insertion did not differ significantly between groups. Overall, while IUA appears to be beneficial for pain management during IUD insertion, the impact of saline infusion on procedural discomfort remains unclear.
