Primary Outcome Measures

Troponin I
Cardiac troponin I levels were calculated in ng/mL using the i-CHROMAII portable fluorescent analyzer manufactured by BoditechMedInc. (South Korea). Normal range: <0.4 ng/mL.
С-reactive protein
С-reactive protein concentrations in plasma were determined using the biochemical analyzer Biosystems BA-200 (Spanish company, Barcelona) according to the manufacturer's instructions.

5. Study Description

Brief Summary
Abstract Troponin is one of the cardiac biomarkers and its high level correlates to high risk of cardiac myocytes damage. C-reactive protein (CRP) in cardiosurgery participates in the Systemic Inflammation Response Syndrome, and heart-lung apparatus is a powerful stimulator of the systemic inflammatory reaction. Objective: To assess effect of anesthetics on troponin I and СRP in mitral, tricuspid and aortic valve replacement/plastic in adult. Methods. Single-center prospective randomized controlled clinical study. A total of 95 patients were assigned randomly into three groups according to the type of anesthesia: the first group of 32 patients with propofol, the second group with sevoflurane - 32 patients, and the last - 31 patients were with isoflurane. Levels of the cardiac troponin I were calculated in ng/ml с using a portable fluorometric analyzer I-CHROMAII, manufacture of BoditechMedInc (South Korea). Normal range: <0.04 ng/ml. CRP concentration in plasma has been determined using a biochemical analyzer Biosystems BA-200 (Spanish company, Barcelona) according to the manufacturer's instructions. The normal level of CRP is less than 5 mg/l.
Detailed Description
The examination and treatment data of 95 patients operated in the departments of cardiovascular surgery of the City multidisciplinary hospital No. 2 were included in the study. All patients underwent mitral, aortic, tricuspid valve replacement/plasty under cardiopulmonary bypass (CPB) conditions. This research work was conducted between 2021 and 2023. To calculate the sample size, we used the formula n=t2*D*N/confidence interval*N+t2*α, which will allow to identify the static significance of the study. Inclusion criteria: insufficiency of mitral, tricuspid and aortic valves of 3-4th degree; only planned surgeries; age range 40-60 years old; patients corresponding to II-III grade according to the scale of the American Society of Anaesthesiologists. Exclusion criteria: pregnancy; acute coronary syndrome; hemodynamic instability. All patients were assigned randomly into three groups according to the type of anesthesia: the first group of 32 patients with propofol, the second group with sevoflurane - 32 patients, and the last - 31 patients were with isoflurane. The level of cardiac troponin I were calculated in ng/ml using a portable fluorometric analyzer i-CHROMAII, production of BoditechMedInc (South Korea). The normal range: <0.04 ng/ml. The analyzer Triage® Meter Pro of Alere San Diego Inc. production (USA). Three blood samples were taken in the patients before the anaesthesia, in 12 hours post-surgery and in 48 hours post-surgery. Blood samples were taken in the sterile test-tubes, containing no EDTA and heparin, centrifugated and stored at temperature -20 °С to avoid the erroneously low results. CRP concentrations in plasma were determined using the biochemical analyzer Biosystems BA-200 (Spanish company, Barcelona) according to the manufacturer's instructions. The normal level of CRP is less than 5 mg/l. Blood samples were taken in the patients before the anaesthesia, 1st day post-surgery, 3rd and 5th days post-surgery.
