SARS-CoV-2 infection and venous thromboembolism after surgery: an international prospective cohort study.
Surgical patients may be at high risk of venous thromboembolism (VTE). SARS‐CoV‐2 infection has been shown to increase this risk. In this huge international, multicentre, prospective cohort study of elective and emergency […]
Viscoelastic haemostatic assay augmented protocols for major trauma haemorrhage (ITACTIC): a randomized, controlled trial.
Current approaches to trauma resuscitation focus on the timely control of bleeding and correction of trauma-induced coagulopathy using the administration of haemostatic therapy. Over the past decade, targeted and individualized […]
Routine venous thromboembolism prophylaxis may be inadequate in the hypercoagulable state of severe coronavirus disease 2019.
This observationnal study has included 240 consecutive patients with confirmed severe acute respiratory syndrome coronavirus 2 infection admitted to one of three hospitals. One-hundred nine critically ill COVID 19 patients admitted […]
Fibrinogen concentrate to cardiac surgery patients with ongoing bleeding does not increase the risk of thromboembolic complications or death.
In this retrospective, observational study, Waldén et al. describe the occurrence of thromboembolic events and mortality in cardiac surgery patients, depending on whether the patient had received fibrinogen supplementation. The […]
Rivaroxaban compared with standard anticoagulants for the treatment of acute venous thromboembolism in children: a randomised, controlled, phase 3 trial.
In this multicentre, parallel-group, open-label, randomised trial, the authors compared the efficacy and safety of rivaroxaban versus standard anticoagulants in children 0-17 years with venous thromboembolism. Across 107 paediatric hospitals […]
Preterm neonates benefit from low prophylactic platelet transfusion threshold despite varying risk of bleeding or death.
The Platelets for Neonatal Thrombocytopenia (PlaNeT-2) trial, a multicentre randomised clinical trial, found an unexpected overall benefit of a prophylactic platelet transfusion threshold of 25 x 10^9/L compared to 50 x 10^9/L for […]
Association of timing of plasma transfusion with adverse maternal outcomes in women with persistent postpartum hemorrhage.
Early plasma transfusion is believed to improve maternal outcomes in postpartum haemorrhage (PPH) because it could theoretically prevent or treat coagulopathy occurring among women treated for persistent PPH. However, as […]
Four years’ experience of a ROTEM((R))-guided algorithm for treatment of coagulopathy in obstetric haemorrhage.
This important study by McNamara et al. reports on four years of observational data from a large UK hospital and tertiary referral unit, following the introduction of a rotational thromboelastometry-guided […]
Tranexamic acid administration is not associated with an increase in complications in high-risk patients undergoing primary total knee or total hip arthroplasty: a retrospective case-control study of 38,220 patients.
This study was designed to examine whether tranexamic acid, which is a well-established therapy to reduce postoperative bleeding, is associated with adverse events in patients at high risk for a […]
Decreasing Postoperative Blood Loss by Topical vs. Intravenous Tranexamic Acid in Open Cardiac Surgery (DEPOSITION) study: Results of a pilot study.
The authors performed a pilot study comparing topical versus intravenous administration of tranexamic acid. Given the heterogeneity of cardiac surgery patients, the lack of any difference in outcome between the […]
Impact of multidisciplinary pulmonary embolism response team availability on management and outcomes.
Chaudhury et al. retrospectively analysed the outcomes of 769 consecutive adult patients with pulmonary embolism (PE) (as diagnosed by computed tomography PE protocol) for the 18 months prior to and after initiation […]
Association of blood component ratios with 24-hour mortality in injured children receiving massive transfusion.
While the incidence of paediatric trauma requiring massive transfusion is lower than the incidence in adults, little is known regarding the optimal transfusion strategy in the paediatric population. Although optimal […]
4-factor prothrombin complex concentrate is associated with improved survival in trauma related hemorrhage: a nationwide propensity matched analysis.
The authors conducted a retrospective study to evaluate outcomes of severely injured trauma patients who received 4-factor prothrombin complex concentrate (4-PCC) + fresh frozen plasma (FFP) compared to FPP alone. […]
Fibrinogen concentrate as an alternative to cryoprecipitate in a postcardiopulmonary transfusion algorithm in infants undergoing cardiac surgery: a prospective randomized controlled trial.
This is an excellent multicentre prospective randomised trial evaluating the efficacy of fibrinogen concentrate (FC) compared to cryoprecipitate to achieve haemostasis for infants post-cardiopulmonary bypass. The primary outcome was the […]
A regional massive hemorrhage protocol developed through a modified Delphi technique.
The authors noted that large academic centres are very likely to have a massive haemorrhage protocol (MHP) but smaller non-academic hospitals may not. Using a Modified Delphi Method, they convened […]
