[Diagnostic value of some markers of infection in cardiosurgical patients in the early postoperative period].
The diagnostic value of traditional markers of infection and procalcitonin test (PCT) in the early postoperative period was compared in 60 cardiosurgical patients with acquired cardiac diseases and at risk for postoperative infectious complications. The mean age of the patients was 51 +/- 11 years. Preoperatively, all the patients had no signs of infections. ⋯ The persistence of the high level of PCT was observed in Group D where there were the bulk (60%) of infectious complications. As compared with the traditional clinical and laboratory criteria (fever, leukocytosis), PCT is the earliest and most specific marker of bacterial infection in cardiosurgical patients in the early postoperative period. The level of PCT > 3.5 ng/ml within the first 24 hours after surgery is shown to be a predictor of postoperative infectious complications.

Review[Rationale for the use of extracorporeal treatments for sepsis].
Sepsis is the leading cause of disability and mortality among critical patients; moreover, it causes high economic expenditures. Although very much is known about the pathophysiology of this condition and its mediators despite great investments directed to its control, mortality rates remain high. Recent treatment manuals emphasize the value of early goal-oriented therapy and also point to the high efficacy of activated protein C. ⋯ There are reports on its positive clinical results that are likely associated with the effective removal of septic mediators. Human and animal studies, few and rather alike as they are, have yielded promising results. It is evident that the use of these procedures is justified; however, their efficiency in sepsis requires large-scale, correctly conducted studies.

The present literature discusses what effective concentration of xenon may be used to induce adequate anesthesia. To examine the analgesic properties of the substance, 38 patients undergone laparoscopic operations for calculous cholecystitis under informational saturation EEG (INEEG) monitoring were included into this study. All the patients were divided into 3 groups in accordance to the mode of anesthesia maintenance and INEEG monitoring. ⋯ The use of 70% xenon concentration and the standard doses offentanyl (3.1 +/- 1.6 microg/kg/h) resulted in excessively deep anesthesia (38 +/- 4% INEEG). Reduction of the dose of fentanyl on an average to 1.5 +/- 0.8 microg/kg/h permitted more adequate anesthesia; however, an excessively deep anesthesia is encountered in 40% of cases, as evidenced by INEEG. The active use of INEEG monitoring in Group 3 makes it possible to perform an adequate anesthesia (46 +/- 4% INEEG) and to determine the xenon concentration necessary for this, which is equivalent to 42 +/- 11% with the dose of fentanyl of 0.9 +/- 0.8 microg/kg/h.
