Brief Summary

Different concentration of sevoflurane was given to maintain anesthesia. The dose of propofol to maintain BIS between 40-60 and the consumption of rocuronium was recorded and evaluated.

Detailed Description

2 age group of patients was selected, 40-60 years and above 60 years. Maintenance of anesthesia was carried out using different concentration of Sevoflurane, ie MAC 0.5, 0.75 and 1.0. Bis value was kept between 40-60 and the dose of propofol required was recorded. Rocuronium infusion given in a close loop infusion system for different group was tabulated. The results was then analysed.
