View clinical trials related to Dystocia.
Filter by:Labor dystocia is an intransigent, high-profile issue in obstetric care, which causes significant maternal morbidity in low resource settings and maternal dissatisfaction, and increased healthcare costs worldwide. Amniotic fluid lactate, (AFL), values have recently been shown to reflect the metabolic status of the uterus and high levels have a strong association with subsequent need for operative intervention due to dystocia. In sports medicine, it is known that lactic acid can affect muscular performance but be decreased by bicarbonate given orally before physical activity. Main Outcome Measures: If an intake of bicarbonate, one hour before stimulation with oxytocin in cases with a high AFL value, changes the AFL levels and enhances delivery outcome in dystocic deliveries. Design: Randomized controlled trial
The ALGOBASES project is an observational epidemiological study of pain through the collection of pain evaluation questionnaires and information with the aim of creating a descriptive "pain" evaluation in all patients who need to benefit from orthopedic, thoracic or gynecological surgery. The painful symptomatology will thus be evaluated in all its dimensions (demographic data, physical, psychological, socio-cultural components) and linked to the pathology justifying the specialized care. It is planned to collect the same data at each subsequent event in order to allow the determination of predictive factors, pain trajectories according to the type of surgery, and the profile of subjects at risk of acute or chronic postoperative pain.
All physicians, nurses, and nurse midwives working on Labor and Delivery will be required to complete cervical exam simulation training. Data before and after institution of the training will be compared to determine if the training leads to less cervical exams during labor and increases consistency between examiners
This observational study characterizes the relationship between amniotic fluid lactate and uterine electromyography during labor in healthy individuals at term planning a vaginal birth. Additional comparison measures and outcomes measures will be collected and analyzed as exploratory measures.
The purpose of this study is to examine whether transperineal ultrasound as visual biofeedback can be used during labor as an effective tool for shortening the second stage of labor and reducing the need for instrumental delivery, in a prospective randomized design.
the study aims to assess the reliability of ultrasound findings measured by hand held ultrasound probes used by operators with variable experience in a low resource hospital.
The overall objective of this randomized controlled trial is to develop a clinical standard procedure for measuring lactate in amniotic fluid (amniotic fluid lactate = = AFL) during childbirth before oxytocin stimulation is started. The aim is to reduce the need for emergency caesarean section during dysfunctional labour. The aim is also to study how different substances (oxytocin and Samarin®) affect uterine metabolic status during labour. Labour dystocia, i.e. prolonged labour, occurs in up to 30% in primipara deliveries and in about 20% of all the deliveries. In 2016, in Finland oxytocin stimulation was used in 42% of all the deliveries. The uterus, myometrium, is one of the largest muscles in the human body and consists mainly of smooth muscle cells. During the contractions the myometrial vessels also contract, causing momentary hypoxia and activation of anaerobic metabolism: O2 and pH levels of the muscle cell decreases and the lactate concentration increases. After the contraction, the blood circulation is restored and the anaerobic metabolites gradually dissolve. Myometrium requires a sufficiently long break between the contractions to recover. In dysfunctional labour the anaerobic metabolites accumulate in the myometrium. Accumulation of lactate has proved significantly to reduce the spontaneous contractions of myometrium and hinder myometrium calcium metabolism, which in turn reduces the strength of the contractions. Amniotic fluid lactate is known to reflect the metabolic state of the uterus during the labour. Prolonged labour can in many aspects be compared to the athlete's tired muscles. Many of today's athletes try to control the accumulation of lactic acid in their muscles during training by drinking baking soda (bicarbonate) dissolved in water one hour before their physical activity. Bicarbonate is known to function as a lactic acid buffer. Bicarbonate is considered as food and is sold in grocery stores as baking soda and for example as Samarin®. Samarin® is safe to use during pregnancy because as a bicarbonate it does not pass through placenta and does not affect the fetus. The trial aims to research if high AFL values (AFL > 12 mmol/L) in women with labour arrest are best treated by: A) treating the labour according to the hospital's current guidelines during labour arrest, i.e. starting the stimulation with oxytocin and measuring the AFL again after one hour B) administering bicarbonate (Samarin®) dissolved in water one hour before starting the stimulation with oxytocin
Shortening the second stage of labor, the time spent pushing the baby out, is important for positive mother and infant's outcomes. Lack of progress of labor for any reason is the most common reason for cesarean section in women having their first baby and the second most common reason for cesarean section in women who have already had a baby. In 2014, a large study done across the United States showed increases in complications in both mother and infant when pushing was prolonged, including uterine infection, postpartum hemorrhage, more extensive vaginal tearing, shoulder dystocia, 5 minute Apgar score less than 4, infant admission to Neonatal Intensive Care Unit and neonatal infections. Therefore, the challenge is to consider alternative practices in order to maximize a mother's chance of a vaginal delivery and minimize these associated risks to both mother and baby. Mouth guards are used primarily in contact sports, and have been demonstrated to reduce or prevent injury to the teeth. Additionally, it has been proposed that wearing a mouth guard increases the strength of different muscle groups. A recent randomized controlled pilot study including women with their first pregnancy using a dental support device (DSD) during the second stage of labor evaluated the length of the second stage and outcomes. They found a significant decrease of 38% in the length of pushing time in the group that used a DSD. Additionally, there was a decreased rate of cesarean section in this group, however a p-value was not reported. This study only included 64 patients. A second, larger trial did not find a significant difference in pushing time, however the rate of interventions such as a vacuum or forceps-assisted vaginal delivery and cesarean section were much higher in the control group due to prolonged pushing. The results of the second study are contradictory in nature, yet the researchers do not provide hypotheses into why this may be. It is clear from the previously mentioned studies that further research is needed. Our hypothesis is that using such a device would help women to push more effectively during the second stage of labor thus shortening the time needed to push the baby out and increasing the rate of vaginal delivery. The purpose of this study is to determine whether wearing a mouth guard in the second stage of labor affects the length of the second stage of labor and improves mother & infant outcomes.
Transvaginal sonographic measurement of cervical length versus Bishop score in labour induction at term for prediction of Caesarean delivery. This study is prospective study. This study will be carried out in Ain-shams maternity hospital. Sample size of 320 parturients.
The purpose of this study is to randomize women to be exposed during labor to different genres of music and study the effect of each genre on the level of objective and subjective stress as manifested by salivary cortisol and personal stress questionnaires, respectively. Secondary outcomes to be examined are obstetric and perinatal outcomes
