Epidural Analgesia, Obstetric

This prospective, three-arm, non-randomized quasi-experimental study aims to evaluate integrated intrapartum supportive care combined with different pushing strategies among women at 37-42 weeks of gestation who receive low-dose epidural analgesia. Participants receive integrated intrapartum supportive care combined with spontaneous pushing, integrated intrapartum supportive care combined with immediate pushing, or routine intrapartum care combined with immediate pushing. The primary outcomes are the durations of the first and second stages of labor. Secondary outcomes include mode of birth, obstetric interventions, maternal outcomes, and neonatal outcomes.

This clinical trial will compare two different approaches to epidural analgesia during labor to see which approach leads to higher patient satisfaction after delivery. Primary aim: determine whether one approach produces greater postpartum maternal satisfaction. Secondary aims: compare pain control and side effects. Participants are people in labor who receive epidural analgesia. They will receive routine clinical epidural care and complete brief, in-hospital questionnaires about pain and satisfaction. All care is provided by the clinical team and safety practices remain unchanged.

In Belgium, labour epidural analgesia (LEA) has been used for decades in the vast majority of vaginal deliveries (up to 83% of deliveries). Labour epidural analgesia is the most effective and safest way to allow pregnant women a nearly pain-free labour- and birth experience. Recent data showed that the use of LEA was associated with a reduced risk for severe maternal morbidity, neonatal resuscitation and with a reduced risk for low Apgar scores. However, prenatal exposure to labour epidural analgesia has been associated by several study groups with an increased risk for autism spectrum disorder (ASD) in the children, but these studies suffer from several important limitations which may have induced significant bias (e.g., not correcting for unmeasured confounders). Associations with other neurodevelopmental disorders (e.g., Attention Deficit Hyperactivity Disorder (ADHD), oppositional defiant disorder (ODD) and conduct disorder (CD)) and cognitive functioning have not been investigated yet. There is hence an urgent need for a study allowing definitive conclusions by overcoming the limitations of the previous studies. The investigators will perform the first sibling-matched clinical cohort study using a prospective investigator-assessment of multiple domains of cognitive functions. The investigators hypothesize that prenatal exposure to LEA will neither be associated with reduced intelligence nor with more neurodevelopmental disorders. Validating this hypothesis holds the potential to grant women the assurance to confidently receive the most efficacious method for labour analgesia, free from apprehension that it might have adverse implications for their children's neurodevelopment.

The purpose of the study is to learn more about a new device, the EpiZact Epidural Device, that may be helpful for reducing the likelihood of wet tap when a labor epidural is placed. When epidurals are placed correctly the needle stops just in front of the space in the body that contains cerebrospinal fluid. When the epidural is advanced a short distance further, leakage of cerebrospinal fluid can occur. This is known as a wet tap. A wet tap can result in a severe headache and at times other complications. The goal of this clinical trial is to learn if the use of the EpiZact device prevents wet taps in pregnant women receiving epidurals for relief of labor pain. The main questions this study aims to answer are: 1. What the rate of wet tap with the EpiZact device? 2. What is the rate of failed epidural placement with the EpiZact device? All patients in the study will receive an epidural with the EpiZact device. The investigators will compare the results with patients not in the study that receive an epidural without the EpiZact device.
