The Stimulation To Induce Mothers Study

The investigators propose a parallel group randomized clinical trial of intrapartum nipple stimulation versus exogenous oxytocin infusion for nulliparous women undergoing induction of labor near term. The central hypothesis is that intrapartum nipple stimulation to induce labor increases spontaneous vaginal delivery, improves patient-centered outcomes such as childbirth satisfaction, labor agentry, and pain scores, and reduces adverse neonatal and maternal outcomes in nulliparous women. The investigators will pursue the following specific aims: 1) Assess the effectiveness of intrapartum nipple stimulation on the rate of spontaneous vaginal delivery in nulliparous women, 2) Breastfeeding as the sole source of nutrition at time of maternal hospital discharge (Primary Aims); 3) Maximal percent newborn weight loss during the birth hospitalization within 72 hours of life, 4) Determine the effect of intrapartum nipple stimulation on the rate of adverse maternal and neonatal outcomes, 5) Determine the impact of intrapartum nipple stimulation on patient-centered outcomes and 6) In a sub-cohort of women who are enrolled in the trial, investigators will measure the change in oxytocin concentration from baseline to time at which patient achieves a regular contraction pattern.

Mindfulness and Meditation Based Lactation Education on Maternal Breastmilk in the Neonatal ICU

The purpose of this research is to investigate associations between mindfulness and meditation techniques and changes in maternal breastmilk in the mother pumping for her NICU infant.

Oxytocin for Weight Loss in Adolescents

This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in youths with obesity, ages 12-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (1 spray per nostril, 4 times per day) for 12 weeks. Study visits include screening to determine eligibility, 2-part main study visits at baseline, week 8, and week 12, and safety check-in visits at weeks 1, and 4; phone calls at weeks 2, 6, and 10, with a safety follow-up visit 6 weeks after the last dose of study drug. Study procedures include appetite, behavioral, metabolic, and endocrine assessments.

Comparing Intramyometrial Tranexamic Acid and Oxytocin for Blood Loss in Cesarean Section

Cesarean section is the most prevalent operation among women globally, 10-15% (1, 2). Recent research has shown Egypt to be the third-largest country globally, with an estimated 52% cesarean sections (3). However, the cesarean section has many serious complications, including the primary postpartum hemorrhage (PPH) (4). During labor, the average blood loss is about 300 to 400 ml. Bleeding postpartum is known as losing over five hundred milliliter of blood following a vaginal birth and losing over one thousand milliliter after the cesarean section (5). The prime cause of maternal death rate is postpartum bleeding, predominately in poor countries, and the estimated mortality number due to postpartum bleeding is one hundred thousand per year (6). Therefore, it is essential to reduce bleeding during and after CS to diminish maternal mortality and morbidity (7). The most successful technique for decreasing PPH is the active third stage labor management, requiring prophylactic uterotonic drugs like oxytocin, ergometrine malate, prostaglandins (E1, E2, and F2α), and combinations of them, or hemostatic agent as tranexamic acid (Kapron) and Etamsylate (Dicynon) (8, 9).

The Influence of Oxytocin on Intrapartum Fetal Well-being and Delivery Outcomes in Patients Receiving Epidural Analgesia

The aim of this study is to determine the influence of oxytocin on fetal well-being during labor in patients receiving epidural analgesia (ELA) with the use of cardiotocography (CTG) and doppler ultrasonography. CTG is a commonly used technique to monitor the fetal heartbeat and contractions of uterus during pregnancy and labor. The maternal-fetal doppler ultrasonography is a non-invasive method used for the pregnancy surveillance. Various psychological and psychosocial factors impact the perception of labor pain. Its intensity is described differently by each patient - some claim it to be the worst pain that they experienced during their lives. Usually, the labor pain is more severely experienced by the patients giving birth for the first time and those with induced labor. Nowadays, there are many non-pharmacological (e.g. acupuncture, massage, TENS) and pharmacological (anesthetic gas, opioids, ELA) methods of labor pain management. ELA is a regional anesthesia, in which the anesthetic drug is injected into the epidural space with the aim to block the pain experienced by the patient without impacting patients ability to move or push during labor. The safety of the procedure is well-discussed and documented in Cochrane review from 2018, which shows no adverse impact on the proportions of Caesarean section, long-term backache, or neonatal outcomes. It is considered to be a golden standard for labor pain management. Oxytocin is a well-known hormone used for the induction of labor and to stimulate the uterine contraction during labor. The impact of oxytocin alone on CTG pattern and maternal-fetal doppler ultrasonography is discussed in the literature. However, the cumulative effect of ELA and oxytocin remains unclear. Some researchers claim that ELA increases the frequency of uterine contractions and that the additional use of oxytocin leads to higher risk of uterine hyper-stimulation and unreassuring CTG patterns. Whereas the others state that ELA weakens the strength of uterine contractions leading to slow progression of labor and the need to use or increase the use of oxytocin. There are no data on how the cumulative use of oxytocin and ELA impacts the maternal-fetal flows during labor.
