Dose sparing of induction dose of propofol by fentanyl and butorphanol: A comparison based on entropy analysis


BACKGROUND The induction dose of propofol is reduced with concomitant use of opioids as a result of a possible synergistic action. AIM AND OBJECTIVES The present study compared the effect of fentanyl and two doses of butorphanol pre-treatment on the induction dose of propofol, with specific emphasis on entropy. METHODS Three groups of 40 patients each… (More)
