[Assessment of real myocardial energy demand using indirect calorimetry in early postoperative period after cardiac surgery].

Objective: To evaluate actual myocardial energy requirements using indirect calorimetry, oxygen delivery (DO), oxygen extraction ratio (OER), cardiac output (CO) and their components, as well as to study the impact of positive inotropic agent (dobutamine) on myocardial metabolism in early postoperative period after cardiac surgery.

Material And Methods: We measured the main metabolic parameters using indirect calorimetry in 20 patients after on-pump cardiac surgery with cardioplegia. To evaluate the impact of metabolic load on CO, VO and DO, we administered dobutamine 3 µg/kg/min at the second phase of the study.

[Prognostic scale for early detection of various postoperative complications after thoracic aortic surgery: post-hoc analysis of biomarkers].

Objective: To create the prognostic scale based on some biomarkers after thoracic and thoracoabdominal aortic repair.

Material And Methods: We analyzed 114 patients with aortic aneurysm/dissection. The following biomarkers were studied: proadrenomedullin, NT-proBNP, procalcitonin, interleukins 6, 8, 10, tumor necrosis factor, presepsin, highly sensitive troponin I.

[The use of oscillatory respiratory therapy with positive expiratory pressure (PEP-therapy) to restore the functional state of the lungs in patients after cardiac surgery].

Unlabelled: Postoperative pulmonary complications in cardiac surgery patients occur in 10-35% of cases, depending on differences in their definition, patient characteristics and type of surgical intervention, most of them are associated with ineffective coughing and evacuation of bronchial secretions.

Objective: To determine the effectiveness of stimulating the evacuation of bronchial secretions with the help of oscillating PEP therapy carried out during the first three days.

Material And Methods: A randomized prospective study of 60 adult patients after elective cardiac surgery was performed (Clinical Trials.

Microbiota Metabolism Failure as a Risk Factor for Postoperative Complications after Aortic Prosthetics.

Postoperative complications in cardiovascular surgery remain an important unresolved problem, in particular in patients with aortic aneurysm. The role of the altered microbiota in such patients is of great interest. The aim of this pilot study was to determine whether the development of postoperative complications in patients with aortic aneurysm is related with initial or acquired disorders of microbiota metabolism by monitoring the level of some aromatic microbial metabolites (AMMs) circulating in the blood before the surgery and in the early postoperative period.

[Analgesic and opioid-sparing effects of a fixed combination of diclofenac and orphenadrine in the early postoperative period in cardiac surgery patients].

Objective: Evaluation of the effectiveness of a multimodal scheme of postoperative analgesia based on a fixed combination of orphenadrine and diclofenac against the background of patient-controlled analgesia with morphine in the early postoperative period in cardiac surgery patients.

Material And Methods: A prospective, randomized, comparative study evaluated two analgesic regimens. In 20 patients (group 1), «Neodolpasse» (a fixed combination of 30 mg Orphenadrine and 75 mg Diclofenac) was administered immediately after trachea extubation.
