Data presented as mean ± standard deviation. Group L: low flow anaesthesia; Group A: alternative method of low flow anaesthesia; Group V: volatile induction and maintenance of anaesthesia; MAC: minimum alveolar concentration. *Calculated by the difference in weight of the vaporizer before and after anaesthesia; *cost includes cost of the used and the unused wasted propofol, that is, entire vial opened for use in one patient. † for Group V versus Group L as well as Group A.
