Filter by:Postpartum haemorrhage (PPH) is an obstetric emergency and defined as a blood loss of ≥500ml after vaginal birth and ≥1000ml after caesarean section (CS) and/or the need for blood transfusion within 24 hours after delivery (World Health Organization, Recommendations for the Prevention of Postpartum Haemorrhage. 2007; Leduc et al., J Obstet Gynaecol Can, 2009). Since PPH is more common after caesarean deliveries than after vaginal births and the rate of CS is rising over time and will probably continue to rise, the incidence of PPH is expected to increase accordingly. A meta-analysis has shown that routine administration of an oxytocic agent after caesarean delivery leads to a reduced blood loss and decreases the risk of PPH (Cotter et al., Cochrane Database Syst Rev, 2001). The two most commonly used oxytocic drugs after operative delivery are oxytocin and carbetocin, a synthetic oxytocin-analogue. Carbetocin has the advantage over oxytocin of having a longer half-life and therefore reducing the use of additional uterotonics. Based on the findings of reduced cardiovascular side-effects with a short-infusion as compared to a bolus injection found for oxytocin (Thomas et al., Br J Anaesth, 2007), our study hypothesis is that a slower administration rate of carbetocin minimises the cardiovascular side effects without compromising the uterine tone. Therefore, we aim to investigate a short infusion of carbetocin 100 mcg applied in 100ml sodium chlorid compared to a bolus application in women undergoing primary or secondary caesarean delivery. This prospective, double-blind, randomised controlled non-inferiority trial will take place at the University Hospital Basel, Switzerland. We hypothesize uterine contraction not to be inferior (primary efficacy endpoint) and the mean arterial pressure to be higher after a short-infusion than after a bolus administration (primary safety endpoint).
To compare the effects of epidural versus combined spinal and epidural (CSE) anesthesia on the success of Trial of Labor After Cesarean (TOLAC).
Three different regimens of phenylephrine are being evaluated to see if one is superior over the other in the maintenance of cardiac output while keeping normotension and/or treating hypotension experienced when receiving spinal anesthesia for cesarean delivery.
Background Women undergoing Caesarean Section (CS) have an increased risk of postpartum infections compared to women undergoing vaginal delivery. In Denmark the incidence of post-CS infections is 7-10%. The most common infections are endometritis, Urinary tract infections (UTI) and wound infections (WI). Prophylactic antibiotics are effective in preventing postoperative infections and national guidelines recommend that antibiotics should be administered as a single dose immediately before surgical incision. CS is an exception to this pre-incision administration approach. National guidelines recommend administration of antibiotics after umbilical cord clamping to avoid exposure of the child to antibiotics before birth. Recent studies of antibiotic prophylaxis for CS suggest that prophylactic antibiotics administered before incision compared to after umbilical cord clamping may reduce post-CS infections by up to 50%. Two Cochrane reviews from 2012 criticize these types of studies for lack of data for outcomes on the baby and on late infection in the mother. At birth, all mammals must rapidly adapt to intake of complex milk nutrients via the gut and simultaneously tolerate the invasion of billions of microbes. This requires rapid maturation of the digestive and immune functions to avoid gut disorders and infections. Full-term, breast-fed infants normally adapt well, but factors such as caesarean birth, high hygiene levels, antibiotics treatment and formula feeding may inhibit immune development both short and long term. Birth by caesarean section in high-hygiene hospital environments, and widespread use of antibiotics, are factors that reduce gut microbiota density and diversity in the newborn for some time after birth. On the other hand, high-hygiene environments and antibiotics are essential tools to combat infections, especially for the weakest newborn infants. This pilot study will be a feasibility study to the original study, which examines the effect of change in timing of prophylactic antibiotics on the rate of post-CS infections (endometritis, UTI and WI). The pilot study focus on antibiotic and changes in the gut microbiota of newborn infants. The feasibility study will only include pregnant women in Odense with a body mass index below 30, and planned cesarean section.
Pregnant and recently postpartum women are at significantly higher risk of developing a blood clot in their arms or legs known as a deep venous thrombosis (DVT) and/or a blood clot in their lungs known as a pulmonary embolism (PE) compared to their non pregnant counterparts. It is estimated that this risk increases anywhere from 4 to 50 times higher in pregnant versus non-pregnant women and further increases almost 11 fold in the post partum period. This risk is almost doubled when the patient undergoes cesarean delivery. In 2011, the American College of Obstetricians and Gynecologists (ACOG) issued updated guidelines stating that for patients undergoing cesarean delivery with additional risk factors for clot or thromboembolism, protective (prophylactic) treatment with low molecular weight heparin (LMWH) a type of blood thinner should be considered. However, no specific guidelines about which risk factors should be considered, or what medication doses should be used were provided. The American College of Chest Physicians (ACCP) Evidence-Based Clinical Practice Guidelines published in 2012 delineated who should be given prophylaxis based on various risk factors, however acknowledged that the recommendations were based on weak quality evidence. ACOG endorses either once or twice a day dosing for high risk patients after delivery and states that adjustments for obese women should be made on a case by case basis. However, there are limited studies on the dosing of LMWH in specific subpopulations including post operative patients, pregnant patients and obese patients. All of these studies have urged further investigation of the correct dosing for these high risk subjects due to changes associated with pregnancy and the level of medication in the blood that may put these patients at higher risk of venous thromboembolism. Many previous studies have shown that women in these high risk categories do not achieve protective levels of the medication measured with a laboratory test; anti Xa level. The investigators hypothesize that due to their dual risk, obese post-operative recently pregnant women may not be adequately protected with the daily fixed dose and might need more frequent dosing to protect them. The objective of this study is to assess what proportion of women achieve the desired anti Xa level with the fixed daily dose versus twice daily weight based dosing (0.5 mg/kg).
We propose to study the effects on hemodynamics (blood pressure, cardiac output, and central venous pressure) of two doses of bupivacaine for spinal anesthesia during cesarean section: a higher dose of 12 mg to a lower dose of 4.5 mg. We will examine recovery times, incidence of hypotension, and compare pain control and maternal satisfaction during and after cesarean section. We hypothesize that low dose bupivacaine spinal anesthesia will provide equivalent anesthesia for cesarean section compared to conventional dose bupivacaine, with less hypotension, faster recovery time, and enhanced maternal satisfaction. Maternal satisfaction will be assessed by self-reported pain scores, incidence of nausea and vomiting, shivering, and ability to interact with baby in the OR.
The purpose of the CSCAR pilot study is to improve the design of a full-scale trial by determining the patient recruitment rate and participation rate. The objective of the full-scale trial is to determine the optimal method of skin closure after Caesarean delivery in women with chorioamnionitis, which is an acute inflammation of the membranes and chorion of the placenta, seen typically after rupture of membranes with ascending polymicrobial bacterial infection. Women in labour with chorioamnionitis will be randomized at the time of Caesarean delivery to skin closure with either staples or sutures. The women will be followed at 6 weeks and 6 months post-partum in order to establish the occurrence of surgical site infection and wound disruption, as well as evaluation of the scar and other secondary questions. The investigators hypothesis is that closure of skin with sutures will have a rate of wound infection that is no higher than the rate of wound infection when closing skin with staples. The investigators also hypothesize that closure with sutures will have a decreased rate of wound disruption, increased patient satisfaction and decreased length of hospital stay compared to skin closure with staples.
The purpose of this prospective randomised study was to determine the effect of routine cervical dilatation during elective caesarean section on maternal morbidity
The purpose of this study is to examine whether Negative Pressure Wound Therapy is an effective wound treatment compared to conventional wound treatment in the period of time from reoperation to re-suturing in women having surgical wound rupture after Caesarean Section.
The purpose of this study is to examine whether obese women (BMI >= 30) who give birth by caesarean section have a reduced incidence of wound infection and dehiscence when incisional Negative Pressure Wound Therapy is applied prophylactically following caesarean section.
