Viscoelastic haemostatic testing (VHT) has been used to determine hyperfibrinolysis and hypofibrinolysis. When modified by addition of tissue plasminogen activator (tPA), VHT has been suggested to assess responses to antifibrinolytic therapy and to estimate the concentration of tranexamic acid in patients undergoing cardiac surgery. Despite some evidence that tPA-modified VHT might allow individualisation of antifibrinolytic therapy, further studies are warranted to prove its clinical benefit for postsurgical bleeding, transfusion of blood products, and thromboembolic events.

Perioperative anaphylaxis and the principle of primum non nocere.
Perioperative anaphylaxis is a rare and unpredictable event that continues to cause patient harm. More work is needed to decrease the risk to patients through measures to limit sensitisation, optimise management and investigation, and ensure that patients are not inadvertently re-exposed to allergens. Robust epidemiological data such as that provided by the consecutive GERAP surveys over the past 30 yr have been invaluable in defining the problem, identifying emerging allergens, acting as a catalyst for change, and stimulating research.
