Filter by:Preeclampsia is a multifocal syndrome reported in 2-8 % of pregnancies. It is diagnosed in the second half of pregnancy by two separate measurements of systolic blood pressure ≥140 mmHg and/or a diastolic blood pressure ≥ 90 mmHg in the same arm and proteinuria >300 mg in 24 h urine collection. The risk for serious complications such as pulmonary edema, cerebrovascular accidents, coagulopathy, and hemorrhage is 10 to 30 fold higher among parturients with severe preeclampsia. Severe preeclampsia is defined by one or more of the following clinical features: severe hypertension (systolic arterial pressure 160 mmHg and/or diastolic arterial pressure 110 mmHg on more than one occasion at least 4 h apart while the patient is on bed rest, renal dysfunction (serum creatinine >1.1mg/dl or doubling of serum creatinine in the absence of another renal disease, platelet count less than <100,000 mm3, acute pulmonary edema, epigastric pain not responding to medical treatment, new-onset cerebral and visual manifestation, hemolysis, elevated liver enzymes and low platelet count syndrome (HELLP syndrome)
The recommended position of the mother under caesarean section after spinal anesthesia is 15 degrees left. However, recent research has challenged the basic principles and practicality of the left-turn 15 degree position. Higuchi et al used nuclear magnetic imaging to directly prove that in the supine position, the position of the full-left 30 degrees of the full-term pregnancy of the full-term pregnancy relieved the inferior vena cava compression and the left-angle of 15 degrees did not. Therefore, there are more and more controversies about the choice of cesarean section position. This experiment aims to explore effects of different positions (15 degrees left, 30 degrees left and supine) for elective cesarean section on lumbar anesthesia for fetal acid-base balance and maternal Hemodynamic.
The purpose of this study is to compare total opioid consumption by subjects in different treatment groups. Another purpose of this study is to assess how well EXPAREL works, collect any safety data and assess your satisfaction using EXPAREL.
Introduction: Placental transfusion supports an important blood transfer to the neonate, promoting a more stable and smooth transition from fetal to extra-uterine life. Cesarean section, especially elective one, reduces the placental transfusion, mainly because of uterine atony. Therefore, during an elective cesarean section umbilical cord management may play a relevant role on blood passage to the neonate and, as consequence, it may affect neonatal hematological values and cardiovascular parameters. The most effective way to manage umbilical cord in in elective cesarean section remains to be established. Objective: The aim of the present study is to evaluate the effect of two different methods of umbilical cord management (Early Cord Clamping - ECC vs. Delayed Cord Clamping - DCC) on the hematocrit on the second day of life; in addition, we will assess the effect on perinatal and postnatal cardiovascular parameters. Material and methods: This is a randomized clinical trial on the effect of different cord management newborns born by cesarean sections. After obtaining parental consent, all mothers > 38 weeks' gestation will be assigned to eithr ECC or DCC group in a 1:1 ratio according to a computer-generated randomized sequence. The primary outcome will be the hematocrit on day 2 of life. Secondary outcomes will be pre-ductal oxygen saturation (SaO2) and the heart rate (HR) during the first ten minutes after the birth, arterial blood pressures during the first 3 postnatal days and transcutaneous bilirubin (BT) at day 3 after birth.
Spinal anesthesia is the preferred anesthesia method in cesarean section to provide satisfactory analgesia and muscle relaxant with less impact on respiratory system. However, hypotension often occurred due to the block of sympathetic nerve, causing maternal decline of frontal lobe oxygenation, nausea vomit and the decrease of uteroplacental perfusion. Several measures are used to prevent or treat hypotension caused by spinal anesthesia: prehydration, limb compression, left lateral tilt of operation tables or usage of vasopressors. In the past decade, the most recommended vasopressor to prevent or treat hypotension in spinal anesthesia in cesarean section was phenylephrine, an α-adrenergic receptor, maintaining maternal blood pressure and fetal acid-base state. In clinical work, there are two ways to use phenylephrine : intravenous method with less onset time (several seconds and duration (several minutes) and intramuscular method with longer onset time (10-15 minutes) and duration (1 hour). Many trials demonstrated the protective effect of preventive intravenous phenylephrine on maternal hemodynamics and neonatal acid-base status. However, few trials reported the effect of preventive intramuscular phenylephrine on cesarean section under spinal anesthesia.
At birth, the passage from intrauterine to the aerial life can be considered as one of the most stressful and painful life events. Skin-to-skin contact (STSC) with mother is known to provide numerous virtues and World Health Organisation (WHO) recently supported the introduction of such care among healthy, term-born neonates. Here, the investigators hypothesized that immediate STSC could reduce neonatal, birth-evoked stress and pain. This randomized controlled trial (RCT) aimed to compare the pain and stress response of C-section born neonates that received either immediate STSC with mother (intervention) or classical support and monitoring (control).
In this prospective, randomized, placebo controlled trial the investigators were able to demonstrate the usefulness of prophylactic cefazolin in elective caesarean section versus placebo, irrespective of the timing of administration, ie before skin incision or after umbilical cord clamping
Pregnant women are more likely to form clots than non-pregnant women as pregnancy increases the clotting factors present in the blood. This helps to prevent excess bleeding (hemorrhage) at the time of delivery. Hemorrhage occurs in 5-15% of pregnancies throughout the world, even when delivery is by cesarean section. When hemorrhage occurs the anesthesiologist will normally administer fluids into the woman's vein (intravenously) rapidly to replace the blood that the woman has lost. Two types of fluids are commonly used. One is a salt water solution (saline) and the other is a starch water solution (pentastarch). Use of either or both of these solutions is common during hemorrhage. These same solutions (salt water solution and starch solution) are used at BC Women's Hospital during spinal anesthesia to prevent and treat low blood pressure (a common side effect of spinal anesthesia). This is standard practice whether you are in this study or not. You may also be given, depending on the anesthesiologist's preference, a drug (vasopressor) that causes the blood vessels to become narrow (constrict) to prevent or treat the low blood pressure. Whether you agree to be part of the study or not, your anesthesiologist will be watching your blood pressure closely throughout your operation and if your blood pressure becomes low he/she will treat it as is normally done. Low blood pressure will also occur during hemorrhage. It is therefore important that we determine whether the starch solution, which is more effective than the salt solution in preventing low blood pressure during spinal anesthesia, does or does not affect clotting. Research in non-pregnant adults (male and female) has found that laboratory tests of blood clotting change with these solutions. For saline the evidence in some studies suggests that the blood may clot better than normal while other studies suggest the opposite (does not clot as well). In pregnant and non-pregnant adults the blood does not clot as well with certain starch solutions. The starch solution used at BC Women's Hospital is called pentastarch and no research has looked at its effect on clotting in pregnant women. In non-pregnant adults pentastarch has less effect on clotting than other starch solutions. The purpose of the study is to see how pentastarch (starch solution) and normal saline (water with salt in it) given at the time of spinal anesthesia for elective cesarean section affect the ability of pregnant woman's blood to clot.
