Biological and Clinical Relevance of Quantra Viscoelastic Hemostatic Assay in Hemorrhagic Cardiac Surgery

The goal of this observational study is to assess the correlation between Quantra viscoelastometric assay and laboratory hemostasis biology in a cardiac surgery cohort presenting with acute hemorrhage in the operating room. The main questions it aims to answer are: * is Quantra a valuable surrogate for hemostasis biology in the setting of bleeding cardiac surgery? * are Quantra parameters well correlated with tranfusion thresholds in the setting of bleeding cardiac surgery?

Massive Transfusion in Children-2: A Trial Examining Life Threatening Hemorrhage in Children

The MATIC-2 is a multicenter clinical trial enrolling children who are less than 18 years of age with hemorrhagic shock potentially needing significant blood transfusion. The primary objective of the clinical trial is to determine the effectiveness of Low Titer Group O Whole Blood (LTOWB) compared to component therapy (CT), and Tranexamic Acid (TXA) compared to placebo in decreasing 24-hour all-cause mortality in children with traumatic life threatening hemorrhage.

REVIVE: Reducing Exsanguination Via In-Vivo Expandable Foam

The purpose of this study is to demonstrate safety, effectiveness and benefit-risk profile of ResQFoam for the inhospital treatment of exsanguinating, intraabdominal haemorrhage due to trauma in patients where emergent laparotomy is required.

Optimization Strategies for Blood Transfusion Protocols in the Emergency Treatment of Hemorrhagic Shock

This single-center, prospective, randomized controlled trial was approved by the institutional ethics committee and overseen by an independent data and safety monitoring board. It enrolled patients with hemorrhagic shock caused by trauma or major gastrointestinal bleeding. Using a random-number-table method, participants were allocated to three groups: (1) Control group: standard massive transfusion protocol (MTP) with transfusing type-specific blood components in a 1:1:1 ratio. (2) Type-specific whole-blood group: following emergency ABO typing and cross-matching, type-specific whole blood was transfused. (3) Low-titer group O whole-blood group: in the emergency phase, 4 units of low-titer group O whole blood (anti-A/B IgM titer \< 1:64) were infused; after definitive ABO typing, patients were switched to type-specific whole blood. Clinical data were automatically extracted from the electronic medical record system. Primary endpoints were efficacy (28-day survival), timeliness (transfusion waiting time and time to achieve target mean arterial pressure), cost-effectiveness (total blood consumption and transfusion-related expenses), and safety (transfusion-associated adverse events including TRALI and hemolytic reactions).Statistical analyses included Kaplan-Meier survival curves and Cox proportional-hazards regression, adjusting for confounders such as age and disease severity scores. The advantages and disadvantages of each transfusion strategy were evaluated, and an optimized strategy for emergency blood transfusion in hemorrhagic shock was developed. This strategy was peer-reviewed and refined, culminating in a standardized, multidisciplinary, emergency-transfusion protocol.

Evaluation of Endothelial Glycocalyx in the Surgical Resuscitation of Major Burn Patients

The purpose of this observational study is to examine whether Endotheliopathy of Trauma (EoT) is present in severely burned patients and how it is affected by burn debridement surgery. The main questions it aims to answer are: * Do severely burned patients present with EoT before undergoing burn debridement surgery? * Does the surgical intervention worsen EoT, leading to increased postoperative syndecan 1 (sdc 1) levels compared to preoperative levels? Participants will: * Undergo debridement surgery where the total area of debrided and donor sites covers 20% or more of the Total Body Surface Area (TBSA). * Have their sdc 1 levels measured before and after surgery. * Have perioperative factors analyzed to assess their impact on endothelial damage and glycocalyx functionality. This study aims to provide insight into how surgical resuscitation affects the endothelial glycocalyx in severely burned patients.
