This clinical trial is focused on studying the effectiveness of a treatment to reduce pain during the insertion of a peripheral intravenous catheter (PIVC) in adult women. The study involves the use of a medication called lidocaine, which is applied as a 10% spray. Lidocaine is a local anesthetic, meaning it helps numb the area where it is applied to reduce pain. The trial aims to see if using this spray can lessen the pain experienced when a needle is inserted into a vein, which is a common procedure in medical settings.

Participants in the study will receive either the lidocaine spray or a placebo before the catheter is inserted. The main goal is to measure the level of pain felt by participants using a simple pain scale, known as the Numerical Rating Scale (NRS), which allows individuals to rate their pain on a scale from 0 to 10. The study will specifically look at pain levels in two areas: the back of the hand and the forearm. By comparing the pain levels between those who receive the lidocaine spray and those who receive the placebo, researchers hope to determine the effectiveness of the spray in reducing pain.

The trial will be conducted in a controlled and randomized manner, meaning participants will be randomly assigned to receive either the lidocaine spray or the placebo, and neither the participants nor the researchers will know which treatment is being given until the study is completed. This approach helps ensure that the results are unbiased and reliable. The study is expected to provide valuable insights into pain management during routine medical procedures, potentially improving the comfort and experience for patients undergoing similar treatments in the future.
