Filter by:Sodium bicarbonate is often used by athletes to improve their muscle's ability to contract and power their activity. It works by decreasing the risk of lactic acid build-up, which causes cramping and fatigue. Some research suggests that using sodium bicarbonate in labour could help to improve the ability of the uterus to contract, helping to prevent labour dystocia (stalled or slow progress in labour). This could ultimately increase the chance of spontaneous vaginal delivery. This research is being done to investigate whether drinking sodium bicarbonate (commonly known as baking soda) dissolved in water as a hydration drink could benefit women in labour and increase the chance of a vaginal birth. In order to answer this question, pregnant people from London, Markham and Mississauga midwifery practices are being recruited to participate in this study. Participants will be randomly assigned to one of two groups when they are admitted to hospital in labour. One group will be asked to drink normal fluids of their choice while they are in labour (usual care). The second group will be asked to consume a drink made of baking soda and water, as well as normal fluids of their choice. Mode of birth and the use of birth interventions will be compared between the two groups. Infant outcomes will be compared to ensure that the use this drink in labour is safe. A risk of consuming sodium bicarbonate is gastrointestinal disturbance. The number of people who reported gastrointestinal upset will also be compared between the two groups. If this study shows that those who drank sodium bicarbonate in labour had an increased chance of vaginal birth and that it is safe, this low-cost, low-risk treatment has the potential to reduce birth interventions for pregnant people and their babies.
Primary Outcome:- GDM Diagnosis Secondary Outcomes:- Pre-eclampsia diagnosis. Cesarean section delivery due to labor dystocia defined as protracted or arrested progress of labor using labor partogram.
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
The purpose of this study is to evaluate if the rate of emergency caesarean section can be reduced if adhering to a dynamic labour progression curve compared to a static progression curve for first time mothers without jeopardising maternal and neonatal outcomes
The ultimate objective is to test the hypothesis that an 'accelerated titration' protocol for labour augmentation with oxytocin reduces the risk of caesarean births relative to a 'gradual titration' protocol. The aims of this pilot feasibility are: 1. To assess the feasibility of a large multi-centre randomized control trial comparing the two above oxytocin protocols (accelerated titration versus gradual titration for correction of dystocia). 2. More specifically, to identify potential challenges in the study implementation, particularly with respect to patient recruitment, randomization, blinding, and compliance/adherence to the labour management guidelines and study protocols. 3. To obtain preliminary data on the acceptability of the accelerated oxytocin titration protocol among obstetrical providers and participants.
