Comparative Assessment of the Time of Patients’ Stay in the Intensive Care Unit After Mitral Valve Replacement With Preservation of the Posterior Leaflet and Complete Removal of Subvalvular Structures

Abstract

The aim is to evaluate the effectiveness of time spent in the intensive care unit and the use of inotropic drugs after mitral valve replacement surgery with preservation of the posterior leaflet with comparison of complete removal of subvalvular structures. Material and methods. The study included 60 patients, including 28 patients after surgery with preservation of the posterior mitral valve leaflet and 32 patients after surgery with complete removal of subvalvular structures. The average age of the patients was 45.9±12.0 years. Inclusion criteria were the time spent in the intensive care unit after surgery, the use of inotropic drugs, and the duration of use of the ventilator. Results. In comparison, the control group in the intensive care unit received more inotropic drugs. In the main group of renal doses - 21 (75%) patients received dopamine - 2.38±0.21 micrograms per kilogram minute, adrenaline - 0.021±0.003 micrograms per kilogram minute. Cardiotonics were not received at therapeutic doses. Above therapeutic doses - 2 (7.14%) patients received (dopamine) - 8±0.01 micrograms per kilogram minute. In the second group of renal doses - 23 (71.87%) patients received dopamine 2.24±0.54 micrograms per kilogram minute, adrenaline - 0.021±0.001 micrograms per kilogram minute. Therapeutic doses of 5 (15.6%) patients dopamine - 5.2±0.4 micrograms per kilogram minute, adrenaline - 0.04±0.001 micrograms per kilogram minute. Above therapeutic doses of 2 (6.25%) patients, dopamine is 8.2±0.02 micrograms per kilogram minute, adrenaline is 0.07±0.003 micrograms per kilogram minute.
