Abstract:
Objective To investigate and compare the effect of orally or intranasally administered borneol on ketamine‐mid‐azolam anesthesia anesthetized rats′regained consciousness and cognitive functions .Methods The rats were trained to escape laten‐cy and divided into 6 groups:control group ,model group ,low dose oral borneol group ,high dose group oral borneol group ,low dose intranasal borneol group and high dose intranasal borneol group ,16 rats in each group .All groups were given general anesthesia ,be‐side the control group .The reflex recovery time ,blood gas analysis ,escape latency and space exploration capability were recorded and compared within groups .Results Compared with the control group ,PaCO2 ,P(A‐a)DO2 and latent escape time increased (P<0 .05) ,pH ,PaO2 and times of platform across decreased in the model group (P<0 .05) .Compared with the model group ,the righ‐ting reflex test time ,times of platform across and latent escape time decreased (P<0 .05) ,blood gas analysis improved (P<0 .05) in intranasal borneol groups and oral borneol groups .The righting reflex test time ,blood gas analysis and times of platform across had no significantly differences within borneol oral groups(P> 0 .05) .Compared with low dose oral borneol group ,latent escape time decreased in high dose oral borneol group (P<0 .05) .Compared with borneol oral groups ,the righting reflex test time ,times of platform across and latent escape time decreased (P< 0 .05) ,blood gas analysis improved (P< 0 .05) in intranasal borneol groups .Compared with low dose intranasal borneol group ,the righting reflex test time and latent escape time decreased (P<0 .05) , blood gas analysis improved (P<0 .05) in high dose intranasal borneol group .Conclusion Intranasal borneol could reduce righting reflex test time and improve cognitive function by improving the blood gas analysis .
