Non-Invasive, Highly Specific Detection of Oxytocin in Biological Fluids
Non-Invasive, Highly Specific Detection of Oxytocin in Biological Fluids
This study will aid in the development of a research instrument for rapid and highly sensitive detection of perinatal salivary oxytocin, by non-invasive means. There will be two study cohorts: Induction of labor cohort (20) and Cesarean delivery cohort (5) for a total of 25 participants.The standard clinical protocols for administering oxytocin to human subjects at Lucile Packard Children's Hospital will be followed. Oxytocin will be prescribed and dosed as per standard of care with no change due to study enrollment. The study will only involve sampling of saliva and blood.
The general hypothesis to be tested is that 1) the sensor will accurately report the levels of oxytocin in saliva samples as compared with standard reference methods and 2) the sensor yields rapid (<20 minutes) oxytocin results with minimal discomfort to subjects. Overall, this will allow to optimize the administration of oxytocin, and for a better understanding of the blood concentration and effects of oxytocin on mother and child.
Oxytocin, a neuropeptide hormone, plays an important role in the dynamic function of the brain and a variety of complex social behaviors including affiliation, sexual behavior, social recognition, and aggression. Oxytocin is best known for its role to facilitate the birth process through induction of uterine smooth muscle contractions. Oxytocin is primarily used to induce labor, and contract the uterus after delivery. Oxytocin is considered the first line uterotonic to prevent and treat uterine atony and manage postpartum hemorrhage. Currently, there is no instrument that is capable of point-of-care oxytocin detection. A practical research tool to monitor peripheral levels of both endogenous and exogenous oxytocin is therefore needed to better understanding the pharmacokinetics and pharmacodynamics of oxytocin in the mother, fetus and newborn. A better understanding of drug concentration and effect may lead to optimal dosing and better management of induction of labor and/or uterine atony after delivery.
With increased research on the importance of oxytocin monitoring, a bedside oxytocin monitor is envisioned that would allow healthcare professionals to improve our pharmacokinetic/dynamic understanding of oxytocin and to monitor and adjust the dose of oxytocin administered during childbirth. Currently, there is no instrument that is capable of point-of-care oxytocin detection.
