Clinical Trial Summary

Primary aim of this study is to analyse contemporary labor patterns by measuring rate of dilatation and head descent via transperineal ultrasonography. Labor curves will be generated using data regarding rate of dilatation, head-descent obtained via transperineal ultrasonography. Factors which are known to effect duration of labor will be taken into account.


Description:

Intrapartum sonography is rapidly advancing field in the management of obstetrics labor. Traditional approach to labor management consists evaluation of cervical dilatation, head position and head descent via digital examinations. Rate of progress is evaluated using data of available labor curves. Unsatisfactory progression is either treated with labor augmentation or cesarean section depending on the degree and duration of labor retardation. Transperineal ultrasonography is able to assess cervical dilatation, fetal head descent and head position. Data obtained from analysis of labor via transperineal ultrasonography is not available. This research's primary aim is to generate labor curves using data obtained via ultrasonographic measurements.

Outcome

Type Measure Description Time frame Safety issue
Primary Duration of active labor Duration of active labor will be calculated in minutes, in a reverse fashion, beginning from time of birth and going back to first time of measurement. From time of initial admission until the time of birth, up to 36 hours No
Primary Rate of cervical dilatation advancement as measured by transperineal ultrasonography Rate of cervical dilatation assessment will be measured in millimetres/hour in a reverse fashion beginning from the time when maximum dilatation is achieved and going back to time of first measurement. From time of initial admission until the time of birth, up to 36 hours No
Primary Rate of angle of progression advancement as measured by transperineal ultrasonography Rate of angle of progression advancement will be measured in metric degree in a reverse fashion beginning from the last measurement taken and going back to first measurement taken. From time of initial admission until the time of birth, up to 36 hours No
Secondary Effect of amniotomy on duration of active labor Effect of amniotomy on the duration of labor will be assessed in minutes by analysing the different time points in different labor processes when amniotomy has taken place. From time of initial admission until the time of birth, up to 36 hours No
