The Effects of Anesthetic Drugs on Hemodynamic Changes in Cardiac Surgury and the Assotiation Between Gene Polymorphysim and Different Heart Diseases :a Pharmacogenetics Study

This study is a non traumatic and non intervention study, and will use a large sample of clinical research, the number of subjects to be enrolled in the study group are 200 cases. The basic information of the study was included in the study before the operation. During the operation, the investigators need a collection of participants's arterial blood and monitor the hemodynamic index and anesthesia depth by bispectral index(BIS) . Further more，the investigators will follow up the participants' condition after operation.Dividing the patients into different groups according to their clinical features.The relationship between vital signs and the depth of anesthesia was analyzed and compared between different groups.Blood samples collected during the operation were detected by gene test. Comparing the results of genetic testing and clinical data analysis, then the investigators will find the differences in the expression of the gene polymorphisms of anesthetic drugs in the circulating function.
