Abstract: 0haective To observe which concentration of pentobarbital sodium induces lower mortality when obtaining the same anesthetic effect in rabbits．Methods New Zealand rabbits were divided into 1％pentobarbital sodium group and 3％pentobarbital sodium group．The anesthetic effects and mortality were observed．Results There is no significant difference of anesthetic effects between the two groups．but 1％pentobarbital sodium group achieved a lower mortality(P<0．05)．Conclusions We should replace 3％pentobarbital sodium with 1％ pentobarbital sodium when anesthetizing rabbits because 1％pentobarbital sodium induces lower mortality and equal anesthetic effect compared with 3％pentobarbital sodium．
