Filter by:Since the 2000s, many prognostic scores were developed to predict traumatic haemorrhage. Most of these studies were retrospectives based on registers. Due to missing data on death due to bleeding, these studies chose to predict the massive transfusion risk as a surrogate of haemorrhagic death. These scores include clinical parameters (vital signs), laboratory values (Haemoglobin, lactate, Base excess) and/or imaging (CT or ultrasound) values. The scores showing best performance are the Trauma Associated Severe Haemorrhage (TASH) score, developed and validated on the German register (DGU-Register) and the ABC score developed and validated in the United States of America. However, the majority of these scores cannot be applied at the trauma scene due to the unavailability of laboratory and imaging values. Therefore, their clinical utility remains unclear. To overcome the need for diagnostic tests, authors have developed and recently validated a clinical prognostic score in identifying trauma patients with, or at risk of, significant haemorrhage based on predicted probabilities of death due to bleeding: BATT score. This score was developed from an international cohort using data from 271 Trauma Centres in 41 countries on 5 continents and uses first clinical parameters at initial assessment. The BATT score predicts death due to bleeding and has been validated on a large population in England and Wales. It could also predict massive transfusion, as a surrogate of haemorrhagic death, earlier at the trauma scene. Its feasibility and external validation would make its clinical utility superior to other scores while identifying a greater number of patients requiring early management. Our study is an external validation of pre-existing prognostic scores of traumatic haemorrhages (TASH , ABC and BATT score) at different times of care (Scene of Injury, admission at the trauma room) in order to assess their overall performance, discrimination and calibration in the prediction of massive transfusion, and haemorrhagic death. The objective of the study is to assess a comparison of score performances (Overall performance, discrimination and calibration). Due to the study population (STR), which is partly integrated into the German DGU-Register, the investigators expect good transportability of the TASH score to the Swiss Trauma Registry in terms of overall performance, discrimination and calibration. The ABC score should show lowers results in terms of discrimination due to its validation on small cohorts exclusively in North America. The new BATT score predicting death due to bleeding has been validated on a large English cohort of more than 100,000 patients. It identifies all patients with haemorrhage and not only patients who have received a massive transfusion subject to survival bias. In this context, the BATT score provides good discrimination with only simple physiological variables available at the trauma scene. In case of its external validation on the STR as part of our study, its feasibility would make its clinical utility superior to other pre-existing scores, while identifying a greater number of patients requiring early management. Its application would activate a massive transfusion plan directly at the trauma scene and save precious time.
to determine safety and efficacy of Tranexamic Acid in reducing blood loss during Myomectomy in our institution.
Research Objective: Primary outcome -To compare efficacy Intrauterine vs Sublingual MISOPROSTOL in addition to Oxytocin in reducing blood loss of post-cesarean section in high risk women Secondary outcome -To study Hemoglobin/Hematocrit change, need of uterotonic agents, need of blood transfusion, adverse drug event of Intrauterine vs Sublingual Misoprostol plus Oxytocin compare to Oxytocin alone Hypothesis: -Intrauterine MISOPROSTOL plus Oxytocin is not inferior to Sublingual MISOPROSTOL plus Oxytocin in reducing blood loss of post-cesarean section in high risk women
This study sought to develop and validate a new risk stratification score (Henan predicting the risk of intracerebral hemorrhage score, Henan-PRIHS) based on intra-arterial contrast enhanced Flat Detector CT (IA-CEFDCT) to predict symptomatic intra-cerebral hemorrhage (sICH) after stroke thrombectomy.
Inherited bleeding disorders (IBD) consist of a heterogeneous group of diseases including coagulation and/or platelets defects and more rarely vascular dysfunctions. A family of four patients suffering from unexplained excessive bleeding has been followed clinically in France for many years. Recently, whole exome sequencing (WES) of DNA allowed the identification of a heterozygous genetic variant which segregated to family members with bleeding diathesis. The aim of the study was to better characterize the phenotype by studying VWF and platelets in affected family members ultimately contributing to the pathogenesis of a bleeding diathesis.
The aim of the study is to develop an accessible, reproducible ultrasound tool for objective clinical measurement of brain circulation in preterm infants in order to identify infants being at risk for preterm brain injury at an early stage. In the future, the results of this study might be useful to select those infants for early interventions aimed at preventing brain injury. In this study we will identify the normative values of the internal cerebral vein velocity in a reference cohort of stable preterm infants. This stable group of preterm infants is defined as all preterm infants with a birth weight appropriate for gestational age, and without major complications (such as a severe intracranial hemorrhage, severe hemodynamical instability, birth asphyxia) or major congenital malformations. In this group we will identify subgroups based on moments of clinical instability (sepsis, temporary hypotension, NEC, need for invasive respiratory support) or based on outcome parameters (IVH, PVL, developmental outcomes)
The purpose of this study is to conduct a randomized, single blind, controlled intervention trial to observe the therapeutic effect of kidney-tonifying and tune up Chong-Ren hemostasis Chinese medicine periodic therapy for dysfunctional uterine bleeding based on objective Chinese and western medicine evaluation standard.
Retrospective analysis of surgical patients with relevant gastrointestinal bleeding situations and indication for endoscopy for bleeding
This study evaluates the incidence of postoperative bleeding after oral surgical procedures in patients taking direct oral anticoagulants and in patients taking vitamin K antagonists.
The purpose of this implementation research study is to generate evidence that informs the successful uptake and adoption of the Ellavi Uterine Balloon Tamponade (UBT) within Kenyan postpartum hemorrhage (PPH) management programs. The investigators aim to improve the likelihood that the Ellavi UBT will be integrated into the Kenyan health care system by obtaining critical feedback from stakeholders and health care providers on the barriers and facilitators towards its successful adoption and roll out. The research will be done in three purposively selected University of Nairobi affiliated hospitals in Nairobi county, Kenya. This study will therefore be exploratory and use a non-experimental design. The study team will train all obstetric healthcare staff (i.e. obstetricians, midwives, medical officers, clinical officers) involved in PPH management at the participating healthcare facilities on use of the Ellavi UBT. The investigators will then gather feedback from the obstetric healthcare workers (post-training and post-PPH) to understand the barriers to and facilitators of use in order to evaluate acceptability and feasibility among facilities providing different levels of care (level 4, level 5 (county), level 6 (tertiary)). This process will help to generate training and facility level recommendations for improved uptake and integration into the local maternal care package. Case report forms and semi-quantitative surveys will be completed by obstetrical care providers to evaluate the primary outcomes of acceptability and feasibility by measuring: context of use, accuracy of use, perceptions of the device, user confidence, acceptability, usability, facilitators of use, barriers to use, use-patterns, and insights into training effectiveness. The secondary outcomes will include financial data to determine the cost of introducing the Ellavi UBT into the Kenyan PPH management protocols and the health system. The study will not involve the storage of biological samples. There is not a direct benefit of the study to the individual participants. All study participants will sign consent forms.
