This study focuses on managing labor pain during childbirth using oxycodone, a pain-relieving medication. The research examines how this medication works during labor and its effects on both the mother and newborn. Oxycodone hydrochloride is given as an injection under the skin to help control pain during childbirth.

The main purpose of this research is to study how oxycodone moves through the body of women in labor and measure its levels in both the mother’s blood and the umbilical cord at the time of birth. The medication will be administered as a solution for injection with careful monitoring of the maximum daily dose. The treatment period lasts up to two days, during which the medication’s effectiveness and safety will be evaluated.

During the study, researchers will collect blood samples from mothers and umbilical cords to measure medication levels. This information will help create a model showing how the medication behaves in the bodies of women during labor. The research aims to better understand the use of this pain medication during childbirth and its safety for both mother and baby.
