Abstract：Objective To estimate the change in cardiac hemodynamics of generally anesthetic patients with wave intensi‐ty ,and explore the clinical application value .Methods We selected 63 patients of generally anesthetic patients who were divided into propofol group (group 1 ,n = 30) and etomidate group (group 2 ,n = 33) at random ,then detected every group patients before and after induction of general anesthesia to wave intensity (W1) in the right common carotid artery so as to get the data of accelerating wave intensity (W1) ,decelerating wave intensity (W2) and negative area (NA) ,to compare the results of the above data .Results ① Comparing with the before ,the blood pressure ,heart rate ,W1 ,W2 ,NA were reduced after the in duction of general ansthesia by propofol ;and differences were statistically ( P < 0 .05) ;After induc‐tion of general anesthesia by propofol ,LVEF was not significantly statistical significance ( P > 0.05) .After induction of general anesthesia by etomidate ,the blood pressure ,heart rate ,LVEF ,W1 ,W2 and NA were not significantly statistical significance ( P > 0 .05) ; ② Comparing with the etomidate ,the blood pressure and W1 were reduced after the in duction of general ansthesia by propofol and differences were statistically ( P < 0 .05) ;and heart rate ,LVEF ,W2 ,NA were not significantly statistical significance ( P > 0 .05) .Conclusion The wave intensity technology can evaluate the comprehen‐sive function of the heart and vascular system in patients with general anesthesia more comprehensively and accurately .It’ s expected to be providenoninvasive and more effective choice of general anesthetic and new monitor method to clinic .
