Filter by:Certain types of surgery are associated with occult blood loss, which is hard to detect intraoperatively by intermittent conventional, invasive Hb concentration measurements using the clinical standard of Hb monitoring by satellite laboratory analysis (Hbsatlab). The investigators want to see whether continuous non-invasive transcutaneous Hb measurement using a finger sensor (SpHb), (a) reduces the total time (area under the curve, AUC) a patient's Hb is below a predetermined transfusion threshold (HbAUC) for administration of red blood cell concentrate (RBC), and (b) prevents a decrease in total oxygen delivery (DO2) possibly associated with transfusion below a critical haemoglobin concentration. Furthermore, the investigators want to study if SpHb monitoring changes the timing of RBC administration and reduces the need for intra- and post-operative RBC transfusion.
Post partum Hemorrhage (PPH) is one of three main causes of death in pregnant women. Oxytocin is widely used for prevention of PPH. Some studies suggested misoprostol as an alternative treatment when Oxytocin isn't available. The aim of this study is to compare the safety and efficacy of Oxytocin and misoprostol for prevention of PPH.
The incidence of pulmonary hemorrhage (PH) was about 1.3 per 1,000 live births. PH occurs mainly in preterm ventilated infants with severe respiratory distress syndrome (RDS) who often have a PDA and have received surfactant. Although not clear, the cause of PH is thought to be due to a rapid lowering of intrapulmonary pressure, which facilitates left to right shunting across a patent ductus arteriosus and an increase in pulmonary blood flow. Prospective uncontrolled studies that used surfactant for PH in neonates have shown promising results in treating PH.In this study we aimed to evaluate the effect of two different natural surfactants in neonates with pulmonary hemorrhage.
The mortality rates from Acute Variceal Haemorrhage remain significant and first line therapy may fail in 15-25% of patients. The self-expandable metal stent has been described in case series as having a very high efficacy at control of haemorrhage from oesophageal varices when used as rescue therapy. This randomised controlled trial aims to assess for any potential superiority of the stent over 'standard' endoscopic techniques as primary or rescue therapy for bleeding oesophageal varices.
The registry of acute stroke under new oral anticoagulants (RASUNOA) is a German multicenter, prospective, observational registry performed at about 50 study centers covering about 50.000 acute ischemic strokes and 6000 acute intracranial hemorrhages per year. Study enrollment will be consecutive. The RASUNOA registry study center is the University Medical Center of the Principal Investigator (Heidelberg, Germany). The registry will focus on treatment decisions and concepts in patients being under treatment with a new oral anticoagulant and suffering from acute ischemic or hemorrhagic stroke.
This is a study to learn more about a drug called Tranexamic acid (TA), otherwise known as Lysteda, and whether or not this drug can decrease menstrual blood loss in young women and lead to an increase in the quality of life. Menorrhagia in young women with bleeding disorders is typically treated with a combination of treatments including hormonal contraceptives. However, there are barriers to hormonal contraception use in younger adolescents. Tranexamic acid is taken orally during the first 5 days of menstrual bleeding. The purposes of this study include: To test the safety and efficacy of Lysteda in adolescent females. To learn how well Lysteda works in decreasing menstrual blood loss. To see if parents and children participating in this study think the drug is improving their quality of life. Lysteda has been approved by the Food and Drug Administration for use in patients > than 18 years of age but not for younger patients.
Non-invasive monitoring to measure changes in blood volume.
The broad objective of the study is to determine if the Bakri Postpartum Balloon is effective in preventing morbidity and mortality from postpartum hemorrhage (PPH) as part of a standardized management algorithm. Specific Objectives - To estimate the rate of morbidity (including operative intervention and peripartum hysterectomy) and mortality secondary to PPH in 4 academic centers after introduction of a standardized protocol for management of PPH, but prior to the inclusion of the Bakri Postpartum Balloon as part of the protocol. - To estimate the rate of morbidity (including operative intervention and peripartum hysterectomy) and mortality secondary to PPH in 4 academic centers after introduction of a standardized protocol for management of PPH, after the inclusion of the Bakri Postpartum Balloon as part of the protocol. - To compare morbidity - To generate preliminary data for (a) a larger confirmatory study of the use of the Bakri Postpartum Balloon in centers with surgical and blood transfusion services, and (b) design of a pilot study of the use of the Bakri device of temporary control of PPH in settings outside of surgical centers (such as by trained midwives or emergency transport personnel).
This study will recruit patients who have recently had a submacular haemorrhage (bleed under the part of the retina responsible for detailed vision), as a complication of wet age-related macular degeneration (wet AMD). Wet AMD is a very common disease where abnormal blood vessels form under the retina and leak, causing a significant reduction in vision. The study will investigate treatment of the bleed with various combinations of the two drugs: tissue plasminogen activator (tPA) - designed to dissolve the blood clot; and perfluoropropane (C3F8) - designed to shift the blood clot away from the central part of the retina (the macula). tPA is a commonly used 'clot-buster' drug for the treatment of stroke. C3F8 is a gas commonly used in eye surgery. Patients recruited will be divided into four groups: control group that receive none of the above drugs; one group that receives only tPA; one group that receives only C3F8; and one group that receives both. All patients will receive the current gold standard treatment for wet AMD, ranibizumab (Lucentis®). The aim of the study is to improve vision in a condition, which left untreated, would cause severe visual loss.
To determine if a manual blood loss can be detected using the non-invasive blood monitor.
