title: The evaluation of uterine activity. A comparative analysis in 100 primiparous patients.
abstract: A comparative analysis has been made of the assessment of uterine activity with the use of both Montevideo units and an automated, on-line method in 100 primiparous patients. The two methods were found to agree well during the active phase of labor. The discrepancies found in both the latent phase and the second stage of labor are discussed. Our assessment is that the automated, on-line method gives a more realistic estimate of the actual uterine work involved in all stages of labor.
