Activity level during a one-hour labor check evaluation: walking versus bed rest.

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Clinical Trials

Background:

• Assessing labor progression is crucial for optimal maternal and neonatal outcomes.
• The optimal activity level during a labor check evaluation remains debated.
• Low-risk, nulliparous women at term are a key population for labor management studies.

Purpose of the Study:

• To determine if bed rest or walking during a 1-hour labor check evaluation impacts progression to delivery.
• To compare cervical changes and time to delivery between bed rest and walking groups.
• To evaluate the predictive accuracy of the 1-hour labor check for delivery within 24 hours.

Main Methods:

• Randomized controlled trial involving nulliparous, full-term, low-risk women.
• Participants were assigned to 1 hour of either bed rest or walking.
• Cervical dilatation, comfort, and time to delivery were assessed. Predictive values were calculated.

Main Results:

• No significant differences in cervical dilatation, time to delivery, or number of deliveries within 24 hours were observed between bed rest and walking groups.
• Maternal comfort levels were similar in both activity groups.
• A positive 1-hour labor check evaluation (≥1 cm change) had a high positive predictive value (88.2%) for delivery within 24 hours.

Conclusions:

• Activity level during a 1-hour labor check evaluation does not influence delivery progression or time to delivery in low-risk women.
• Patient preference should guide activity choices during labor assessments.
• A negative 1-hour labor check evaluation is not a reliable predictor of delivery beyond 24 hours.
