Misoprostol

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.

Oli is a predictive, non-invasive device, intended to be placed on the participant's maternal abdomen during the intrapartum period, which can alert healthcare professionals of an impending cumulative blood loss of ≥500 ml (abnormal postpartum uterine bleeding) or cumulative blood loss of ≥1000ml (postpartum haemorrhage) at least 1 hour in advance of birth. This study is being undertaken to assess the performance of Oli measuring cumulative blood loss ≥500ml and ≥1000ml, as well as evaluate its safety profile.

The objective of the study is to investigate the treatment of marginal ulcers with Low Thermal plasma in an endoscopic setting. By a treatment of the ulcerated areas with argon plasma with low power settings (\~ 1 W) we hypothesize that the size of the ulcers will shrink, and the healing is accelerated compared to standard of care alone. Patients will benefit from this minimally invasive approach compared to a much more invasive surgical approach that comes with higher risks and hospital stay length time. From a societal and scientific perspective, this study aims to extend the well-documented clinical benefits of plasma technology - from external wound healing to internal ulcer treatment - within an endoscopic framework. The success of this study could pave the way for broader applications of LTP in the treatment of other endoscopically accessible conditions such as peptic ulcers, duodenal ulcers and esophageal ulcers. This advancement has the potential not only to improve patient outcomes through less invasive methods, but also to position LTP as a cornerstone in the future of gastroenterological wound management strategies.

This research project aims to enhance the safety of childbirth by using advanced computer models to predict the risk of postpartum hemorrhage (PPH). PPH is a significant concern for mothers during and after delivery. Current risk assessment tools are basic and do not adapt to changing conditions. This study will investigate whether a new and recently validated model for predicting PPH, combined with a provider-facing Best Practice Advisory (BPA) regarding currently recommended strategies triggered by an increased predicted risk, can improve perinatal outcomes. This study will compare the current category based risk assessment tool with a new, enhanced prediction model which calculates risk based on 21 factors, automatically updates as new information becomes available during labor and, if elevated, provides a provider-facing Best Practice Advisory (BPA) recommending consideration of strategies that are institutionally agreed to represent high-quality practice. Investigators hypothesize that the enhanced care approach will result in improved perinatal outcomes. The goal of the study is to improve the wellbeing of mothers during childbirth by harnessing the power of modern technology and data analysis.

This is a randomized controlled trial examining whether the use of misoprostol or pitocin, in combination with a foley catheter, is more effective at inducing labor in patients with a gravid BMI that is considered obese.

This trial uses a special imaging technique with a dye to help doctors see blood flow during gastric bypass surgery. It aims to reduce complications like ulcers and leaks by ensuring good blood flow at surgical connections. The study focuses on patients having this type of weight-loss surgery.

Labor analgesia is an important component of the care of laboring patients. A known side effect of combined spinal and epidural anesthesia (a type of labor analgesia) is an increased incidence of category II fetal heart rate tracing (defined below) and low blood pressure. The study team aims to study if a prophylactic dose of ephedrine will decrease the occurrence of this type of tracing after combined spinal epidural (CSE) anesthesia placement. Ephedrine is not currently routinely used as prevention for category II tracings or low blood pressure. The use of Ephedrine in this study is investigational (this is the first time that the drug has been studied for its effect on these conditions). Fetal heart rate (FHR) tracings are classified into three categories. In clinical practice, FHR tracing categories are used as a guide to obstetric management and suggest the following approach: * Category I tracing is "reactive" and reassuring → may continue labor * Category II tracing is neither category I nor category III. For obvious reasons, category II is the broadest and largest category, consisting of various FHR tracing patterns that do not fit into either category I or category III. * Category III tracing is non-reassuring → expedited vaginal or cesarean delivery recommended. A Category II tracing is not diagnostic. Most pregnancies have at least one Category II tracing. There is not always an identifiable reason for a Category II tracing. Ephedrine is a medication that causes an increase in heart rate and blood pressure while also causing some degree of relaxation of the uterus therefore improving uterine blood flow. It has been used in the obstetric population for over 50 years without issues. The dose that the research team will administer, 7.5 mg, is below the dose the research team will often administer to treat hypotension (low blood pressure).

Oxytocin is the first-line drug to promote contraction of the uterus and prevent atony immediately after delivery. Nonetheless, unpredictable uterine atony refractory to oxytocin affects roughly 250,000 parturients annually in the U.S. and rates are increasing. This two-part study will measure the action of oxytocin at cesarean delivery. The first part will measure the pharmacokinetics of a single intravenous (IV) dose of deuterium-labeled oxytocin. The second part will measure the pharmacodynamics of all plasma oxytocin to see how concentrations correspond to the contractile effect on the uterus. After delivery of the fetus, study subjects will receive a bolus of IV deuterated oxytocin followed by an unlabeled oxytocin infusion. Venous blood samples drawn at multiple time points (within 1 hour after delivery) will be analyzed for plasma concentrations of labeled and unlabeled (endogenous + exogenous infused) oxytocin over time. Plasma concentrations will be compared with 0-10 uterine tone scores measuring uterine contraction strength, to describe the concentration-effect relationship. The goal of this study is to define both the pharmacokinetics and pharmacodynamics of oxytocin in parturients to help identify the cause(s) of failed first-line oxytocin therapy.
