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.
