Sonopartogram. The Next Step in the Delivery Room

Objectives: * Evaluation of the correlation between the sonographic parameter and clinical findings (e.g. digital examination) in any cephalic (not only occipital anterior) position * Examination of the relationship between various sonographic parameters * Determination of intraobserver and interobserver variation in obtaining the sonographic measurements * Analysis of the temporal variation of the different sonographic measurements in normal spontaneous vaginal delivery versus obstructed labor in fetuses with occiput anterior versus those with persistent occiput posterior * Establishment of a sonopartogram that should replace in an objective way Friedmann * Establishment of cut-off values that may help clinicians to choose between vaginal operative delivery or caesarean section * Another interesting aspect of intrapartum transperineal ultrasound imaging is whether there is a psychological benefit to the patient in being able to follow on the ultrasound screen how fetal head descent and position are being assessed objectively.
