Abstract: Abstract Objective: To investigate the clinic effect of remifentanil on fast tracking cardiac anesthesia. Methods: 120 cases in our hospital from May 2014 to May 2015 were selected as study objects. They were divided into control group and observation group, 60 cases in each group. The control group was given fentanyl combined with propofol. The observation group was given remifentanil and propofol. Compared the hemodynamics, ICU observation time, extubation time, hospital stays of the two groups and clinic effect of the two groups. Results: MAP and HR post-anesthesia of the two groups was obviously lower than before-anesthesia. Decreased degree of control group was obviously greater than observation group. ICU observation time, extubation time, hospital stays of observation group was obviously shorter than control group, the difference was statistically significant (p<0.05). Conclusion: Application of remifentanil on fast tracking cardiac anesthesia has significant clinic effect. Hemodynamics is more stable and can shorten the ICU observation time, extubation time and hospital stay. It is worthy of wide application.
