Correlation of Bispectral Index Score and Total Intravenous Anesthesia (TIVA)

• Status: Terminated
• Trial end date: 2014-09-01
• Target enrollment: 0
• Participant gender: All

Summary

General Anesthesia is usually produced by an intravenous agent and then maintained with a breathing agent till the surgery is completed. However, there is a recent trend to produce and maintain general anesthesia solely with an intravenous agent, such as propofol, in view of its advantages. This delivery method is called Total Intravenous Anesthesia (TIVA). The depth of general anesthesia can be measured by an anesthetic depth monitoring device called Bispectral Index (BIS). The use of BIS to determine the depth of anesthesia has been well established whenever a breathing agent is used to maintain general anesthesia. However, the validity of using BIS with TIVA has not been adequately investigated. This study will compare the BIS values at different doses of TIVA in order to establish any correlation between the two. If such a correlation is established, BIS monitoring can safely be recommended to determine anesthetic depth under TIVA.
