Abstract

Objective. To study the effectiveness of the pharmacological myocardial preconditioning with inhaled NO during operations with cardiopulmonary bypass (CPB).

Material and methods. The study included 90 patients who underwent surgery with CPB. Three groups of patients were created: the first (control, 30 patients); the second (30 patients) – inhaled nitric oxide before and after CPB; the third (30 patients), nitric oxide inhalation was carried out daily for three days before surgery, during surgery – before and after CPB. The level of troponin I (cTnI) was determined daily for 3 days of the preoperative period, as well as 12, 24 and 48 hours after surgery; used clinical and functional indicators.

Results. An increase in the level of cTnI was noted after the 2nd inhalation of NO (by 71.4% of the initial value), in the absence of these changes in the control group. Statistically lower levels of cTnI were observed at 12, 24, and 48 hours after surgery, VIS, a decrease in the length of stay in the ICU and acute cardiac failure rate in patients of the 3rd group.

Conclusions. Inhaled nitric oxide has a clinically pronounced effect of pharmacological myocardial preconditioning. Its effectiveness depends on the duration of its inhalation administration and is most pronounced after a course of three procedures.
