Virtual Reality-Based and Face-to-Face Relaxation Programs in Pregnant Women With Preeclampsia

Preeclampsia, affecting 2-8% of pregnancies globally, is a leading hypertensive disorder in pregnancy. It is clinically characterized by elevated blood pressure (≥140/90 mmHg) after the 20th gestational week, often accompanied by proteinuria and systemic complications such as thrombocytopenia, liver dysfunction, and cerebral symptoms. This condition poses significant risks for both maternal and fetal health, increasing the likelihood of organ damage, preterm birth, and long-term cardiovascular and neurodevelopmental complications. Non-pharmacological interventions, including relaxation techniques, have been explored for symptom management. Progressive muscle relaxation (PMR) has shown efficacy in reducing stress, anxiety, and blood pressure. Recently, virtual reality (VR)-based relaxation techniques have gained attention for enhancing stress relief and improving health outcomes. This study aims to compare the effects of VR-based PMR with in-person PMR on maternal and fetal outcomes in preeclamptic pregnancies.

Evaluation of the Fetal Response to Intrapartum Digital Fetal Scalp Stimulation to Identify Intrapartum Fetal Hypoxia.

The main objective of this study is to evaluate whether digital fetal scalp stimulation improves fetal well-being in fetuses with suspicious or pathological cardiotocographic recordings, showing an improvement in cardiotocographic recording patterns and normal values in intrapartum fetal scalp blood results. Upon detection of a suspicious or pathologic cardiotocographic recording, the investigators need to perform an objective verification of fetal well-being. Currently, fetal scalp blood is the reference test to assess intrapartum fetal hypoxia, according to the protocols of the Spanish Society of Gynecology and Obstetrics. This procedure lasts about 5 minutes and consists of taking a small sample of the fetal scalp, through a vaginal exploration, the blood is collected in a thin tube and analyzed by a machine in the delivery room obtaining the results in a few minutes. The investigators emphasize that this test is not part of the study, as long as the monitor is suspicious or pathological, it will be performed according to protocol to objectively assess fetal well-being. Currently there are studies that support the use of fetal scalp stimulation as an alternative technique to assess intrapartum fetal well-being and predict neonatal outcomes, but they also highlight its limited evidence. Digital fetal scalp stimulation is a NON-invasive method, as no instrument is required and fetal stimulation is a 30-60 second surface rubbing pressure, which is performed manually, through vaginal exploration, the same technique the investigators use to assess dilation during the labor process. Each patient will be randomly assigned to a study group: Experimental group: before the extraction of capillary blood from the fetal scalp, fetal head stimulation will be performed, a technique that poses no risk to the baby. The researchers need the consent of the participants to perform this technique and collect data. Control group: fetal head stimulation will not be applied, but data from the clinical history necessary for this study will be collected. In no case will extraordinary or unnecessary tests be performed for participation in this study. This study will have an Informed Consent document. This study will be carried out at the Fundación Jiménez Díaz and Zarzuela and will include 182 patients for 24 months.

Can Conventional ECG Technology Capture Fetal Cardiac Activity?

This is a feasibility study for a new application for capturing fetal cardiac activity. The objective of this study is to determine if it is feasible to capture a fetal ECG signal using a Holter ECG device. As comparison we will use a standard Doppler Fetal Heart Rate (FHR) device.
