UnlabelledIn this study we sought to determine the propofol requirement and hemodynamic effects as guided by bispectral index (BIS) analysis during induction of anesthesia. Sixty patients were enrolled in this study. Propofol, 2 mg/kg, was given to Group I for induction. Propofol was administered for induction until loss of response to verbal commands and until BIS values were around 50 to Groups II and III. After induction, the smallest BIS value was different in Group I. Decreases in total propofol dose were 36% and 43% in Groups II and III respectively as compared with Group I. The dose of propofol assessed by BIS analysis results in an important reduction of propofol requirement without side effects.ImplicationsHypotension during induction of anesthesia with propofol is common. This study has shown that propofol requirement assessed by bispectral index analysis during anesthesia induction may decrease the dose and side effects and provide for satisfactory depth of anesthesia.
