BACKGROUND: The main aim of this study was to compare the effects of propofol and sevoflurane induction on the echocardiographic parameters of Mitral Stenosis (MS) patients.
METHODS: Prospective, randomized, outcome-assessor-blinded clinical trial in 80 adults with MS undergoing mitral valve replacement. Patients were randomized to receive General Anesthesia (GA) induction with either propofol (Group P) or sevoflurane (Group S). The primary objective was to assess the changes in mean gradient after 3 minutes of GA induction. Secondary objectives were to assess the changes in echocardiographic Doppler parameters and hemodynamic variables.
RESULTS: Compared to pre-induction values, there was significant reduction in the peak and mean gradients as well as peak velocity, in both the groups after GA induction. The Mitral Valve Area calculated by continuity equation (MVA-c) and by pressure half time (MVA-p) were increased in Group S after GA induction. On comparison between the two groups, Group S showed lower pressure half time and greater MVA-p (p = 0.0099) and MVA-c (p = 0.0316) than Group P after GA induction. Mean arterial pressure decreased at the 1st and 3rd minute following GA induction in both groups. The Heart Rate (HR) increased at the 1st and 3rd minute in Group P whereas it reduced at both the time points in group S.
CONCLUSION: Even though both anesthetic agents reduced transvalvular gradients in MS patients, sevoflurane was associated with a greater increase in estimated valve area and a reduction in heart rate compared with propofol. These findings suggest more favorable short-term hemodynamic and echocardiographic changes with sevoflurane at the studied time points.
