A variety of laboratory tests have been developed, which can diagnose a number of both congenital and acquired disorders of platelet function. Many tests of platelet function measure the ability of platelets to adhere to each other, forming platelet aggregates, which represent the major constituents of hemostatic plugs and of arterial thrombi. Light transmission aggregometry (LTA) is still considered the gold standard of platelet aggregation tests, but other platelet aggregation-based tests are also available...

As a leading cause of maternal death, postpartum hemorrhage (PPH) remains a worldwide obstetrical problem. However, in most cases, mortality and morbidity can be averted if efforts are immediately undertaken to achieve hemostasis. Uterine balloon tamponade has been shown to provide effective control of PPH and avoid more invasive surgical procedures and even the emergency peripartum hysterectomy. Recent clinical recommendation suggests that balloon tamponade should be considered earlier in the treatment cascade in conjunction with uterotonic agents to ensure hemostasis in the most timely fashion and maximize clinical outcomes...

BACKGROUND: Intraoperative hemorrhage can sometimes be massive in patients with spinal metastasis of renal cell carcinoma (MRCC). Preoperative embolization and local hemostatic agents are routinely use in spinal tumor surgery, but there have been no comparisons between these methods. This report compares the efficiency of various methods of bleeding control and their influence on outcome and survival after decompression procedures for MRCC. MATERIALS AND METHODS: This was a retrospective case-control study of 54 patients with hypervascular extraosseous MRCC...

The choice of hemostat is determined by the situation and the degree of hemorrhage. One common hemostat, the nonwoven dressing, is easy to handled and controls severe bleeding on wider wounds. In this study, chitosan-based nonwoven dressings with recombinant batroxobin (rBat) were used as efficacious hemostatic dressing agents. Hemostatic agents need to absorb blood quickly in the early stages of blood coagulation cascade to rapidly and effectively control of excessive hemorrhages. To date, most studies of hemostatic agents focused on a single material and hemostats composed of multiple materials have not been studied sufficiently...

Postoperative bleeding with its important socioeconomic cost is associated with an increased morbidity and mortality. It causes hemodynamic instability, increases blood loss, and multiplies the number of transfusions required. Especially in vascular or aortic surgery, postoperative bleeding can become a life-threatening complication due to anticoagulant or antiaggregation preoperative status or postoperative coagulation dysfunction after a high level of heparinization. Presently described is the case of a patient who underwent an aortic valve and ascending aorta replacement...

BACKGROUND: Although intracompartmental bleeding is one cause of traumatic compartment syndrome, no previous studies have defined the role of hemostatic stability in the development of traumatic compartment syndrome. Therefore, to investigate this issue, we identified the relationship between antiplatelet/anticoagulant medications and the development of traumatic foot compartment syndrome. In addition, as a possible predictor of compartment syndrome, we evaluated the utility of blood-clotting tests in the prediction of traumatic foot compartment syndrome...

Objective: To compare the efficacy of fibrin-based hemostat and cellulose-based hemostat with traditional procedures in patients undergoing thyroid surgery. Methods: Between January 2012 and December 2016, 255 patients were scheduled to undergo total thyroidectomy at Surgical Clinic Nis. The patients were randomized to: Group-I use of classic surgical procedures to achieve hemostasis, Group-II use Surgicel and Group-III use Beriplas. Results: A statistically significant reduction of surgical time was found for Group-I compared with Group-II and III (p≤0...

BACKGROUND: Topical hemostatic agents are useful when hepatic hemorrhage is difficult to control. The aim of this study was to evaluate the hemostatic efficacy and safety of a biodegradable polyurethane-based adhesive, MAR VIVO-107 (MAR), in comparison with a clinically used fibrin glue. METHODS: Thirty female New Zealand white rabbits were randomly assigned to 3 study groups as follows: MAR (n = 10), fibrin glue (n = 10), and saline groups (n = 10). After standardized partial liver resection was performed, each agent was immediately applied to the wound area...

BACKGROUND: Transfusion therapy is associated with increased morbidity, mortality and costs. Conventional coagulation tests (CCT) are weak bleeding predictors, poorly reflecting coagulation in vivo. Thromboelastometry (ROTEM) provides early identification of coagulation disorders and can guide transfusion therapy by goals, reducing blood components transfusion. OBJECTIVE: The aim of this study is to describe coagulation profile of critically ill patients using ROTEM and evaluate the association between CCT and thromboelastometry...

The graphene aerogels' potential for use as both a hemostatic agent and dermal delivery system has scarcely been investigated. In this study, we used a sol-gel process for generating dry and stable composite aerogels based on graphene oxide (GO) and polyvinyl alcohol (PVA). Furthermore, we incorporated natural extract of País grape seed (SD) and skin (SK), rich in Proanthocyanidins (PAs or condensed tannins). The effect of the incorporation of the grape extracts was investigated in relation to the aerogels' structure, coagulation performance and the release of the extracts...

Context: Delivery of slow-release local anesthesia has considerable potential for postoperative analgesia. Fibrin gel has shown huge potential for drug delivery, but has not been fully investigated for the delivery of local anesthetics nor has whether incorporation of anesthetic drugs into fibrin alters its mechanical properties. Aims: This study aimed to evaluate the effects of bupivacaine inclusion on the mechanical and kinetic properties of fibrin as measured by thromboelastography (TEG)...

Liver transplantation is an ever-evolving field and understanding coagulation management and hemostatic therapies is essential for good outcomes. In this review, we discuss current monitoring tools available in the operating room and the hemostatic agents available to control hemostasis. Multifactorial coagulation defects are discussed and point-of care monitoring is reviewed to guide selection of hemostatic agents when indicated.

Bone wax is a commonly used hemostatic agent with minimal complications. Some of the known complications include inflammation, granuloma formation, infection, and impaired osteogenesis. Several clinical reports of bone wax migration have also been reported. In this paper, the authors present a rare patient of bone wax migration intracranially in a 6-year-old patient who initially underwent craniotomy for the evacuation of subdural hematoma and repair of depressed skull fracture. The patient then underwent craniotomy scalp scar revision several months later...

INTRODUCTION: Hemorrhage is the leading cause of death on the battlefield. Development of chitosan- and kaolin-based hemostatic agents has improved hemorrhage control options. Sparse data exists on the use of these agents in the prehospital, combat setting. We describe recent use of these agents and compare patients receiving hemostatic to the baseline population. METHODS: We used a series of emergency department (ED) procedure codes to identify patients within the Department of Defense Trauma Registry (DODTR) from January 2007 to August 2016...

The aim of this study is to identify, in our center, all cases of foreign-body reactions to hemostatic agents or other prostheses resulting in a radiological suspicion of tumor recurrence. We interrogated our internal database to identify all such cases and systematically evaluated the MRI brain scans of patients: (i) at the time of initial tumor diagnosis, (ii) postoperatively, (iii) and at the time of suspected tumor recurrence. In addition, we reviewed each patient's operative notes and reviewed the histology of all cases following a second surgical intervention...

Hemostasis encompasses an ensemble of interactions among platelets, coagulation factors, blood cells, endothelium, and hemodynamic forces, but current assays assess only isolated aspects of this complex process. Accordingly, here we develop a comprehensive in vitro mechanical injury bleeding model comprising an "endothelialized" microfluidic system coupled with a microengineered pneumatic valve that induces a vascular "injury". With perfusion of whole blood, hemostatic plug formation is visualized and "in vitro bleeding time" is measured...
