Objective- To study the effects of Isoflurane in inducing anesthesia and comparing mask and chamber induction anesthesia in rabbits for the first trial in Iran.Design- Experimental design.Animals- 20 female adult New Zealand White rabbits.Procedures- Animals were divided randomly into two groups.A 40 cm3 Chamber was used in group A with 4-5% concentration of isoflurane and a here face mask was used in group B with 1-1.

5% concentration of isoflurane to induce anesthesia.The concentration of isoflurane increased in 30 second intervals since reached to 4%.Routine ovariohysterectomy was performed in both groups.Duration of induction and recovery, apneuastic period and volume of consumed isoflurane were measured in both groups.Results- Mean duration of induction of anesthesia was significantly shorter in group B in comparison to group A (P0.

05).Conclusion and Clinical Relevance- As concluded use of isoflurane to induce anesthesia in rabbits is feasible and safe in case of available equipments.Mask induction seems more appropriate to induce Hardware anesthesia than chamber.
