Filter by:The purpose of this study to determine the association between postoperative pain after cesarean section and several single nucleotide polymorphisms in SCN9A sodium channels gene.
The proposed study is a pilot randomized controlled trial (RCT) of an electronic patient decision aid (PDA) for antidepressant use in pregnancy. The overall aim of this pilot RCT is to establish the feasibility of future large international RCT of the PDA's effectiveness.
The primary purpose of this study is to assess the responses of pregnant women and their social network to six videos about health in pregnancy. Our goal is to assess a) acceptability and b) understanding of core messages about healthy eating, exercise and weight gain during pregnancy. We will also assess c) non-clinical sources of health information during pregnancy.
This is a continuation study to KUDOS (NCT00266825). The purpose of this study is to follow-up with participants on the original study to determine if the effects of increasing DHA intake during pregnancy increase cognitive development in 2 to 6 year-old children.
Season of birth influences pregnancy for reasons that remain unclear however the answer may lie in the amount of sunshine pregnant women are exposed to. Sunshine, or ultraviolet light (UV) exposure is already known to have benefits for health on heart disease, strokes and depression. In pregnancy, relationships between sunshine exposure are evident in birth weight, preterm birth and risk of blood pressure complications. Vitamin D, the UV generated hormone, was thought to be responsible when low vitamin D levels were associated with these pregnancy complications. However, vitamin D replacement is ineffective at preventing these outcomes, and the investigators hypothesise that this is because it is the UV that is beneficial for pregnancy and it is working through a different pathway. A new understanding of skin function is central to this, with a 2014 study showing that exposing an adult to 20 minutes of low dose UV light lowered their blood pressure and improved blood flow. These investigators demonstrated this was a direct effect of UV on the skin and was mediated by nitric oxide, a chemical central to many aspects of pregnancy including blood pressure regulation and uterine activity. The investigators in this study have funding from Tommy's to investigate if a similar effect is seen in pregnancy on the circulation. The design is similar to the previously successful method and volunteers would be recruited from clinical areas during the second trimester. As both resting and warming for 20 minutes have the potential to have similar effects on the circulation, a control arm will expose participants to these without the UV. This pilot study would involve one visit and measurements taken would include heart rate, blood pressure, arteriography, ultrasound of the uterine arteries and blood measurements of nitric oxide levels. Arteriography is performed using a specialised arm cuff and is safe and non-invasive. A subset of these women would be invited to repeat this in the third trimester to investigate for a difference in effect at a later gestation.
Healthy parturients presenting for scheduled cesarean delivery will have blood drawn and measured for microparticles at baseline, immediately after delivery, and at several time points thereafter.
The main purpose of this study is to explore the impact of the birth environment on women's birth experience and relevant birth outcomes in the experimental Labour room compared to a standard Labour room.
This study is a randomized control trial (RCT) evaluating a Prenatal Walking Program (PWP) in comparison to a Postpartum Prep Program (PPP) comparison group for pregnant women experiencing depressive symptoms. In addition to assessing changes in depressive symptoms, the investigators will examine other key maternal outcomes (maternal functioning, pain, anxiety, stress, fatigue), as well as infant outcomes including birth record data (gestation, weight, Apgar scores, etc) and careful, in-person assessment of infant neurobiological functioning at 30 days postpartum.
Comparative study of Ropivacaine and Ropivacaine with dexmedetomidine in transversus abdominis plane (TAP) block for post-operative analgesia in patients undergoing Caesarean Section.
Spinal anesthesia is the main technique for caesarean section. This anesthesia is followed by a hypotension in 40% to 90% despite preventing tools. Hypotension is responsible of foetale and maternal suffering. It would be interesting to have a tool that could detect patient who are at risk to have hypotension.This study consist in measuring variations of under aortic velocity peak (ΔITVAo) which estimate the modification of the cardiac output by Trans thoraciq echography.
