(16 342 703.21±3785.60)，there showed no significant differences between any two different time points(P>0.05).Conclusion：In the compatible solution composed of Propofol injection and Etomidate fat emulsion injection with volume ratio of 1∶1，the emulsion particle size distribution，ζ potential，pH value，the content of the two drugs，as well as the H1-NMR peak areas of 4-H of Propofol and 5-H peak of Etomidate are not change significantly ......
