NCT ID: NCT05527236 Completed - Clinical trials for Patient Satisfaction

The Effects of Breathing Exercises and Virtual Reality Applications During Pregnancy and Labor.

Start date: October 15, 2020
Phase: N/A
Study type: Interventional

Aim and Objectives: The purpose of this study was to determine the effects of breathing exercises and virtual reality applications during pregnancy and labor on labor pain, duration, and birth satisfaction. Background: Conducted studies show that practices such as virtual reality have positive effects on labor. However, there is no study that compares the effects of breathing exercises with virtual reality applications on labor. Design: A randomized controlled experiment was conducted by the CONSORT guidelines. Methods: The study included 114 pregnant women (Breathing Exercise Group:39, Virtual Reality Group:37, Control Group:38). The research was carried out in two stages. In the first stage, for the experimental groups at the 36th-39th weeks of pregnancy, a 10-minute breathing exercise was performed 3 times a week using virtual reality glasses and a breathing exercise device. In the second stage of the study (when the cervical dilatation was 4 cm), the breathing exercise group was made breathing exercises again. The virtual reality group watched a 10-minute video with virtual reality glasses. Once the virtual reality glasses were removed from experimental groups Visual Analogue Scale was applied. Birth satisfaction was evaluated with the Birth Satisfaction Scale within the first 4 hours after the delivery was completed.

NCT ID: NCT05109247 Completed - Labor, Induced Clinical Trials

Prediction of Spontaneous Onset of Labor at Term

PREDICT
Start date: August 22, 2019
Phase:
Study type: Observational [Patient Registry]

The study intends to develop a predictive model of spontaneous onset of labor between 39 and 41 weeks of pregnancy in women carrying singletons and without indication of delivery before this date. The main hypothesis is that a combination of clinical, ultrasonographic, biochemical and/or biophysical variables will allow to differentiate women who will spontaneously trigger their labors from those who will require an induction by the term of their pregnancies. A tool of this kind should aid in the individualization of the management of the final weeks of pregnancy and, at the light of recent evidence, provide support to the decision-making processes.

NCT ID: NCT04437576 Active, not recruiting - Labor Onset Clinical Trials

Pregnancy and Latent Labor Biomarkers and Symptoms to Predict Cervical Dilation at Hospital Admission.

Start date: September 13, 2019
Phase:
Study type: Observational

The proposed pilot investigation is a prospective, observational study of 300 healthy nulliparous women with spontaneous term labor onset. The specific aims of this study are to: Aim #1: Characterize IL-8 (pro-inflammatory biomarker), basal body temperature, maternal heart rate, and electrical activity of the uterus prior to spontaneous onset of labor through the onset of active labor among nulliparous women. IL-8 will be quantified weekly, daily basal body temperature, as well as continuous maternal heart rate and electrical activity of the uterus throughout the transition from late pregnancy into active labor. Aim #2: Characterize latent labor symptoms among nulliparous women in spontaneous labor. Using Likert scale, childbirth-specific, symptom-specific PROMIS measures,45 and open-ended questions will be quantified and characterize latent labor symptoms (e.g., intensity, frequency) and identify relevant themes. Aim #3: Characterize trajectories of labor biomarkers and latent labor symptoms across latent labor duration. A modified growth mixture modeling approach to quantify subgroup phenotypes among nulliparous women in spontaneous latent labor will be employed. Hypothesis 3.1. There will be significant congruence between higher biomarkers (e.g., higher IL-8, more uterine electrical activity) and symptoms that are more intense and frequent. Hypothesis 3.2. At least two classes of laboring women with distinct trajectories of change in biomarkers and symptoms can be identified and will be associated with cervical dilation at hospital admission. Exploratory Aim: Characterize biomarkers among nulliparous women with spontaneous labor onset vs. nulliparous women requiring labor induction for post-term gestation. Weekly IL-8, daily basal body temperature, as well as continuous maternal heart rate and electrical activity of the uterus throughout the transition from late pregnancy into active labor between those whose labor begins spontaneously and those whose labors are induced for post-term gestation will be quantified. Exploratory Hypothesis. There will be different biomarker patterns between women with spontaneous labor onset vs. those without. The Standard descriptive and inferential statistics as well as growth mixture modeling for quantitative aims will be used. The investigators will use thematic development for qualitative aims.

NCT ID: NCT02493192 Not yet recruiting - Labor Pain Clinical Trials

Birth Ball Versus Meperidine and Haloperidol Injection for Pain Relief During First Stage of Labour

Start date: July 2015
Phase: Phase 4
Study type: Interventional

The study was performed at Gregorio Marañón Hospital birth centre. A Randomised Clinical Trial comparing the two methods of pain relief in the first time of labour was carried out. In this study, 110 women in the first stage of labour were allocated in two study groups by a randomised block design. One of them used the birth ball as a pain relief method,and the other one used pethidine and haloperidol injection.

NCT ID: NCT02021539 Terminated - Clinical trials for Obstetric Labor, Premature

The Prognostic Value of Cervical Elastography for Identifying Patients at Risk for Preterm Delivery

ElastoMAP
Start date: February 2014
Phase: N/A
Study type: Observational

The hypothesis tested is that the physical changes associated with cervical ripening result in a detectable decrease in rigidity. The main objective of this study is therefore to determine whether the measured elastographic rigidity of cervical tissues in addition to cervix size can be used to predict delivery within the next 48 hours (creation of a prognostic score).

NCT ID: NCT00433303 Not yet recruiting - Labor Onset Clinical Trials

Correlation Between Coital Activity During Pregnancy and Premature Delivery Related to Prostanoid Receptor Polymorphisms

Start date: n/a
Phase: N/A
Study type: Observational

The purpose of our study is correlate between premature delivery (between week 23-35 of the pregnancy) in women that had intercourse up to 12 hours prior to beginning of labor and polymorphisms in the gene Prostanoid receptor.
