Induced Labor

The goal of this clinical trial is to learn about the safety and performance of the INGA Sensor System when used with the INGA balloon catheter during cervical ripening for labor induction in pregnant individuals at term. Cervical ripening is a process used to prepare the cervix for labor. The main questions it aims to answer are: * Is the INGA Sensor System safe to use during cervical ripening with the INGA balloon catheter? * How well does the sensor system measure uterine contractions and fetal heart rate during cervical ripening? * How does the use of the INGA balloon catheter affect cervical ripening and the time from induction to delivery? * How do participants and healthcare professionals evaluate the usability of the catheter and sensor system? All participants in this study will receive the INGA balloon catheter with the attached sensor system. There is no comparison group. Participants will: * Undergo routine assessments before labor induction, including medical history review, cervical examination, blood pressure and heart rate measurement, and fetal heart rate monitoring * Have the INGA balloon catheter placed in the cervix by a trained physician * Have a small sensor device attached to the external end of the catheter * Undergo standard fetal heart rate monitoring after placement * Keep the catheter and sensor in place until the catheter is expelled naturally or for up to 24 hours * Continue labor induction and delivery according to standard hospital practice * Complete a questionnaire about comfort and usability * Allow collection of information about labor, delivery, and newborn outcomes from medical records Participation lasts from signing informed consent until hospital discharge.

Pregnancy and vaginal birth are the main causes of pelvic floor disorders such as urinary incontinence and pelvic organ prolapse. The levator hiatus - the opening in the pelvic floor muscles through which the baby passes - can be measured on three-dimensional transperineal ultrasound at rest, during pelvic floor contraction and during a Valsalva manoeuvre. Its size and its ability to stretch have been related to how long labour lasts and to how the baby is eventually born, but the evidence comes mostly from women in spontaneous labour, in whom the exact time labour began cannot be established. Women having their labour induced offer a better model, because the time each stage of labour begins is documented. Recently, automated software has made the measurement of the levator hiatus fast and reproducible, which makes it realistic to use in everyday practice. This prospective observational study will enrol 140 women with a singleton pregnancy at 36 weeks or more who are scheduled for induction of labour. Before induction begins, each woman will have a transperineal ultrasound scan of the pelvic floor at rest, on maximum contraction and on maximum Valsalva. The scan does not involve any vaginal probe, radiation or injection, and takes about 15 minutes. The times of each phase of labour, the way the baby is born and the condition of the perineum after birth will be recorded prospectively from the clinical record. The scan will be repeated before hospital discharge and about one month after birth, together with validated pelvic floor symptom questionnaires. The main question is whether the area of the levator hiatus measured on Valsalva before induction is related to the duration of the active, pushing phase of the second stage of labour. The study will also examine the duration of the first stage, the mode of delivery, and how the pelvic floor changes in the first month after an induced birth. Study procedures do not influence clinical care in any way: induction and labour are managed according to standard departmental protocols, and the research ultrasound results are not disclosed to the clinical team.

The goal of this clinical trial is to determine which of two types of standard intravenous (IV) fluids (a combination of 5% dextrose and Lactated Ringers solution and Lactated Ringers solution alone) has a better influence on labor when inducing labor in pregnant women. The main questions it aims to answer are: 1. Does the use of 5% dextrose and Lactated Ringers lead to a shorter labor than the use of just Lactated Ringers? 2. Does the use of 5% dextrose and Lactated Ringers increase the risk of neonatal hypoglycemia when compared to Lactated Ringers? Participants in this trial will be randomly assigned to one of two groups: a group that receives a solution of 5% dextrose and Lactated Ringers, and a group that receives Lactated Ringers alone. Researchers will compare the outcomes of the two groups to see which IV fluid is more effective.
