Lung Ultrasonography and Cardiac Surgery: A Narrative Review.

Pulmonary complications are common after cardiac surgery and are closely related to postoperative heart failure and adverse outcomes. Lung ultrasonography (LUS) is currently a widely accepted diagnostic approach with well-established methodology, nomenclature, accuracy, and prognostic value in numerous clinical conditions. The advantages of LUS are universally recognized and include bedside applicability, high diagnostic sensitivity and reproducibility, no radiation exposure, and low cost.

The immunosuppressive effects of volatile versus intravenous anesthesia combined with epidural analgesia on kidney cancer: a pilot randomized controlled trial.

Background: The aim of this study was to test the hypothesis that the use of inhalational anesthesia leads to higher suppression of the cell-mediated immunity compared to total intravenous anesthesia in patients undergoing kidney cancer surgery under combined low thoracic epidural analgesia and general anesthesia.

Methods: Patients were randomly allocated to either propofol-based (intravenous anesthetic) or sevoflurane-based (volatile anesthetic) anesthesia group with 10 patients in each group, along with epidural analgesia in both groups.

History and Current Status of Cardiac Anesthesiology in Russia.

Anesthesiology, the branch of medicine concerning anesthesia and management of the vital functions of patients undergoing surgery, has played an important role in the development of cardiac surgery. In the middle of the last century, medical professionals had little experience in the treatment of congenital and acquired heart diseases. Progress of cardiac anesthesiology in Russia, as well as in countries across the globe, was due to requests to increase the safety of surgical procedures and to improve survival rates for the increasing number of patients with complex heart diseases.

Mortality prediction in patients with dialysis-dependent acute kidney injury after cardiac surgery with cardiopulmonary bypass.

Background: To build a predictive model for patients with dialysis-dependent acute kidney injury (AKI-D) after cardiac surgery with the cardiopulmonary bypass (CPB), according to disease severity.

Methods: A single-centre, retrospective cohort study was performed to determine the demographic and clinical parameters (including the specific factor, CPB duration) for risk of poor outcome in patients requiring RRT after cardiac surgery with CPB. A new model was built for mortality prediction in these patients on the basis of the identified risk factors and Sequential Organ Failure Assessment score.
