KINETIC Research Study for Breastfeeding Mothers of Infants
STUDY BASICS
Are you planning to wean your baby and stop breastfeeding? You may be able to participate in a research study to help find out if low doses of the non-opioid painkiller ketamine transfer into breastmilk. Participation involves 1 overnight visit with a 12-hour ketamine infusion and providing samples of breastmilk, urine, and blood. Compensation provided.
STUDY PURPOSE
Ketamine is a non-opioid painkiller that is often used after surgery, but little is known about the use of ketamine during childbirth. The purpose of this research study is to help find out if ketamine is transferred into breast milk. Researchers hope their findings lead to a better understanding of the role of ketamine during childbirth and a reduction in the use of opioids during C-section deliveries in the future.

WHAT PARTICIPANTS CAN EXPECT
