Hemodynamic differences in sevoflurane versus propofol anesthesia.
The aim of the study was to compare the effect of sevoflurane and propofol anesthesia on myocardial contractility during laparotomic cholecystectomy using transesophageal echo-Doppler. In the study, 40 patients were randomized into two groups, depending on whether they received sevoflurane or propofol anesthesia. Heart rate, cardiac index, stroke volume, left ventricular ejection time and acceleration were measured 10 minutes after induction of anesthesia, 1 minute and 25 minutes after incision. The results were analyzed using paired t-test and ANOVA. Significantly lower values were found for all parameters after the initial measurement (p < 0.05). In the sevoflurane group, stroke volume decreased from 66 +/- 6.2 ml/beat to 65 +/- 6.4 ml/beat and to 63 +/- 5.6 ml/beat 1 minute and 25 minutes after incision respectively. In the propofol group changes were from 64 ml/beat to 58 +/- 10.5 ml/beat to 58 +/- 8.6 ml/beat. Stroke volume was significantly higher in the sevoflurane than in the propofol group (p < 0.05). Sevoflurane anesthesia allows a better hemodynamic stability during laparotomic cholecystectomy.
