Abstract: AIM: To investigate the effects of etomidate and propofol on insulin resistance in rabbits with type 2 diabetes mellitus(T2DM). METHODS: 18 successed model of the T2DM rabbits were randomly divided into three groups (n=6): control group (group C), etomidate group (group E), 1% propofol group (group P). 0.9% sodium chloride infusion for group C, 1% propofol infusion for group P, etomidate infusion for group E respectively, before the start of administrating (T1), administrating for 2 h (T2), 4 h (T3), 6 h (T4) and after the administration for 24 h (T5) , pumping blood through ear vein to determine BG,IN,TNF-α,Cor and calculate IRI = (BG × IN)/22.5 by HOMA-IR formula. RESULTS: Compared with group C, group E and group P could significantly reduce the concentration of serum BG (P<0.05), the effect of Group E was more stronger and more durable. Compared with group C, group E and P could reduce serum TNF-α concentration in vary degree, there were no significant different (P>0.05). Compared with group C, group E and P had lower concentration of serum IN in the different time points (P<0.05). Compared with group C, both of Group E and P could significantly reduce the concentration of serum Cor (P<0.05). The effect of Group E was more stronger and more durable. CONCLUSION: Both etomidate and propofol can decrease the IR and improve the insulin sensitivity in rabbits with T2DM. Etomidate has a more lasting effect compared with propofol. The potential mechanism of the impact of etomidate,propofol on IR is that the two can inhibit the body's stress response through internal and external.
