The lowest effective concentrations based on the efficacy criteria of complete anesthesia induction within 180 sec and recovery within 300 sec were determined to be 75 mg L-1 (induction 143 +/- 15 sec and recovery time 149 +/- 35 sec) for clove oil, 500 mu L L-1 (induction 145 +/- 27 sec and recovery time 57 +/- 16 sec) for 2-phenooxyethanol and 50 mg L-1 (induction 152 +/- 49 sec and recovery time 88 +/- 24 sec) for benzocaine. The onset of individual phases of anesthesia and recovery times depended significantly on the concentration of the anaesthetic used (p<0.05). An inverse exponential relationship was observed between concentrations of anaesthetic and induction time whereas exponential relationships were observed between concentrations and recovery times for all anaesthetic agents evaluated,eninfo:eu-repo/semantics/closedAccessClove oilbenzocaine2-phenoxyethanolinduction timerecovery timeTurkeyArticle1025335033552-s2.0-84872150121N/AWOS:000298097800005Q3
