Maternal perception of prelabor uterine activity

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Reproductive Health

Background:

• Preterm labor is a significant cause of neonatal morbidity and mortality.
• Early detection of uterine activity is crucial for timely intervention to prevent preterm birth.
• Patient self-assessment of uterine contractions has been proposed as a method for monitoring.

Purpose of the Study:

• To objectively assess patient perception of uterine activity in women at risk for preterm labor.
• To compare patient-identified contractions with objective tocodynamometer data.
• To evaluate the reliability of self-detection for early preterm labor identification.

Main Methods:

• Ambulatory tocodynamometry was used in 44 high-risk women over 8.5 weeks.
• Patients marked perceived contractions on the tocodynamometer data.
• Objective uterine activity was recorded simultaneously.

Main Results:

• Patients identified only 15% of actual uterine contractions on average.
• Numerous false alarms occurred, with marks placed without detectable contractions.
• Multifetal gestation and current preterm labor history impacted perception accuracy.

Conclusions:

• Patient self-detection of uterine activity is not a reliable sole method for early preterm labor detection.
• Objective monitoring tools are essential for accurate assessment in high-risk pregnancies.
• Further research is needed to improve patient education and monitoring strategies.
