Coagulation management remains a challenge for anesthesiologists involved in cardiovascular surgery as the population undergoing surgery becomes older and presents with more comorbidities. These patients are frequently treated with one or more agents that directly affect coagulation. This review will discuss what is known and the treatments available to manage coagulation in the perioperative setting of cardiac surgery. ⋯ The introduction of new drugs with different mechanisms of action adds to the complexity of coagulation management during cardiovascular surgery. Monitoring needs to be developed and improved, especially for evaluating platelet function.

New anticoagulants and new techniques bring challenges and opportunities to the practice of anaesthesia. Existing guidelines may not be up-to-date with these changes, so this review will examine the current research with a view to identifying deficiencies in existing guidelines, particularly those that may guide Australian anaesthetists. ⋯ Despite much interesting recent research, few current guidelines are likely to require modification. Novel pharmaceuticals have risk profiles that are incompletely understood, but will only become evident on phase-4 testing. Australasian guidelines for reversal of warfarin may need to be updated to include advice on the use of recombinant factor 7a.

Chronic obstructive pulmonary disease (COPD) is a common cause of primary hospital admission and also a common coexisting disease among surgical patients. This translational review focused on recent studies related to the perioperative care of COPD patients. ⋯ Perioperative management as well as modern intensive care concepts are based on avoidance of tracheal intubation if possible, use of regional anesthesia techniques and the early liberation from invasive mechanical ventilation. Noninvasive ventilation has become more and more utilized in recent years to stabilize patients with acute exacerbations of COPD and to treat postoperative pulmonary complications in order to avoid reintubation.

To review the recent literature related to pulmonary function testing and how it relates to the preoperative evaluation. ⋯ Pulmonary function testing can be used to quantify lung function, confirm an individual's functional status, evaluate regimen effectiveness, and determine disability. They may be essential in all candidates for lung resection. However, there are limits in the current testing of pulmonary function. There is new evidence that exercise testing may provide better diagnostic and prognostic information about patients with cardiovascular and pulmonary disease.

ReviewStrategies to reduce the use of blood products: a US perspective.
To describe the recent developments in the strategies to reduce allogeneic blood transfusions with emphasis on the impact on clinical outcomes. ⋯ Patient blood management is the timely use of safe and effective medical and surgical techniques designed to prevent anemia and decrease bleeding in an effort to improve patient outcome.
