Abstract:

Abstract： Objective To investigate the application of the Laborpro system to the research and management of labor. Methods The prospective study was designed and 36 singleton term, vertex pregnancies were recruited. The Laborpro system was used to conduct internal pelvimetry, and the data were collected by vaginal examination (VE) vs. anal examination (AE). The system calculations of dilation of cervix and fetal head station were compared with routine vaginal examination measurements. The measurers were blinded to the system results, and 72 and 69 measurements were involved respectively.Results The anteroposterior diameter of pelvic outlet by AE was longer than that by VE about 1 cm. The system result of cervical dilatation was bigger than manual result, and the station of fetal head was higher. The accuracy of assessment of labor progress by senior midwives was better than that by junior midwives:（79.59% vs. 53.85%）and（76.27% vs. 53.84%）.Conclusion Laborpro system offers and advanced technique to measure pelvic, monitor and study labor. The standard guideline of midwife training should be built by using this system appropriately.
