A pilot randomised controlled trial to determine the effect of two designs of partographs, including labour progress lines, on the rate of spontaneous vaginal birth amongst low risk women in labour for the first time: The Partograph Trial

For women in labour for the first time does a partograph with a graduated dystocia line compared to a standard sloping action line increase the likelihood of a spontaneous vaginal birth: Pilot Partograph study 2

Brief summary

The aim of this pilot study is to test the procedures for a larger trial that will compare two different tools (partographs) for measuring progress in labour. In particular we aim to achieve a compliance rate of 85% with both the intervention and control arms of the trial. The outcomes will inform any necessary changes to the main study protocol. If no substantial changes are required the data from this pilot study will be incorporated into the results of the main study

Interventions

The Dystocia line partogram is a visual tool that uses a graduated (stepped) line to indicate whether cervical dilatation, determined by vaginal assessment at regular intervals, is slower than a mean of 0.5cm per hour. The tool is administered by a midwife and the results of vaginal assessments are recorded on the partograph every four hours or as clinically indicated.
