In recent years, we have considerably widened our knowledge of the pathophysiology of sepsis and some procedures, aiming both to relieve symptoms and control the inflammation/coagulation reaction, have proven to be effective in increasing survival. This improves when mechanical ventilation is applied with low tidal volumes, fluid replacement and the use of cardioactive drugs are titrated on the oxygen saturation of hemoglobin in the central venous system and blood glucose does not exceed certain limits. ⋯ The only molecule which has proven to be notably effective in reducing mortality is Activated Protein C interacting on coagulation/fibrinolysis, as well as on inflammation processes. Multinodal modulation of several interdependent processes may be the probable reason for the proven effectiveness of this treatment.

Comparative StudyThrombelastography. Present and future perspectives in clinical practice.
Thrombelastography (TEG) is a method for evaluating the viscoelastic properties of the blood clot, from its formation to its lysis. All major surgeries may be associated with massive blood loss, with blood component transfusion therapy often becoming mandatory. ⋯ With TEG is thus possible to know if bleeding is due to a failure to provide adequate surgical hemostasis, if there is platelet dysfunction, or to detect anomalies in coagulation proteases or their inhibitors, or if the blood loss is associated to early, excessive fibrinolysis. The theoretical advantages of TEG are the ease of performing the test, the fast sample reading times (now 30 minutes) and the informative

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia after preincisional administration of remifentanil.
The aim of this study was to assess postoperative analgesia after preincisional and postincisional administration of remifentanil. ⋯ The preincisional administration of remifentanil followed by a continuous infusion of 0.25 microg kg(-1) min(-1) appears to reduce pain scores and piritramid consumption when compared with a postincisional regimen.

Multicenter StudyA prospective, observational evaluation of a new supraglottic airway: the PAXpress.
Little information is available on efficacy and safety of the new supraglottic device, PA(Xpress), in anesthetized patients. The aim of this prospective observational study was to evaluate the use of this new supraglottic device in clinical practice. ⋯ Although further comparative, randomized studies should be advocated to better evaluate the use of this new supraglottic device, this prospective, observational study demonstrated that PA(Xpress) provides safe and effective airway control during mechanical ventilation in up to 98% of cases.
