Introducing a New Device Fetal Head Station Meter and Comparative the Efficiency of This Device with Vaginal Examination

Backgrounds:Evaluation of the fetal head station in the active phase of labor is performed by repeated vaginal examinations. In this study, the efficacy of the new station meter device was evaluated in comparison with the traditional vaginal examination method.Material and method : In this study women who had inclusion criteria particicipated and new station meter device placed in a sterile condition over the head of the fetus and stayed on until the vaginal delivery.At each time, the need to determine the station of the fetal head was initially determined by vaginal examination and at the same time, the researcher determined the station by using the new device.The comparison between the two determined station at the same time and their correlation was done. Also, the number of gloves used and the number of vaginal examinations and satisfaction of the professor, resident, midwife and participants as well as fever or postpartum infection were studied up to 10 days after delivery.Result:32 mothers were enrolled in the active phase of labor with dilatation of at least 4 cm and a maximum of 10 (average 6.5 cm) cm and effasment from 40% to 100% (mean 60%).Comparison of the station of the fetal head in two methods of using vaginal examination and fetal head station device showed that there is correlation between these two methods and the rate of p in all cases, 6 positions of the head of the fetus (from position -3 to +2 position) iwas significant. (p<0.05). The gloves used for vaginal examination varied by an average of 2.9 ± 5.1 and between 1 and 16, respectively. The number of vaginal examinations averaged 5 times and between 1 to 10 times. Residents, professors, midwives and participants were generally satisfied with using this device for determining the station of fetal head in general. None of the participants showed fever or post partum infection until 10 days after delivery.P less than 0.05 was considered as significant.Conclusion: New station meter device is a simple and accurate device for determining station in active phase of labor. By using this device reduces costs by decrease the number of gloves used and number of vaginal examinations which makes the mother satisfied. So residents, professors, midwives were generally satisfied with using this new device for determining the station of fetal head
