Timing the first post-operative dose of anticoagulants: Lessons learned from clinical trials.
The non-vitamin K antagonist oral anticoagulants (NOACs), rivaroxaban, apixaban, and dabigatran, have been shown in phase 3 trials to be effective for thromboprophylaxis in patients undergoing elective hip or knee arthroplasty. Results from prior studies suggested that the safety of anticoagulants in such patients was improved if the first postoperative dose was delayed for at least 6 h after surgery. The timing of the first postoperative dose of the NOACs tested in phase 2 studies differed among the three NOACs: dabigatran was started 1 to 4 h postoperatively, whereas rivaroxaban and apixaban were started at least 6 and 12 h, postoperatively, respectively. ⋯ First, clinical trials performed before the NOACs were evaluated demonstrated that delaying the first dose of prophylactic anticoagulation until after major surgery is effective and safe. Second, the optimal timing of the first dose of prophylactic anticoagulation after surgery depends on the dose that is selected. Third, the results of the phase 3 trials with NOACs for thromboprophylaxis support the concept that acceptable efficacy and safety can be achieved when the appropriate first postoperative dose of anticoagulant is delayed for at least 6 h after surgery.

Perioperative complications commonly include oxygenation and ventilation abnormalities. The best outcome is associated with prevention. Ventilation impairment may be due to either neurologic compromise such as cervical intervertebral disk disease or severe parenchymal disease, while oxygenation failure may result from either the underlying disease or severe complications such as aspiration pneumonia, volume overload, pulmonary thromboembolism, or acute respiratory distress syndrome. This article reviews the approach to the patient with perioperative complications and provides recommendations on the management approach.

[Protective ventilation reduces postoperative pulmonary complications - Contra].
Protective ventilation is a treatment strategy for patients with ARDS. The main goals are the prevention of de-recruitment and overinflation and hence development of VILI. Therefore, protective ventilation is an individualised therapy by adjusting PEEP and Vt in respect to patient' own volume-pressure-curve. ⋯ However, "protective ventilation" has not been standardised yet, and the adequate Vt and PEEP in an individual patient undergoing surgery has still to be clarified. Therefore, due to inconsistent intraoperative ventilation and methodical flaws it remains questionable if a generalized Vt reduction copes this complex topic. One should be aware that reduction of Vt may increase the rate of atelectasis and has been shown to be associated with increased mortality.
