Abstract:
Objective: To study the effect of three different doses of propofol, midazolam and etomidate on short latency somatosensory evoked potential(SLSEP). Method:Ninety patients undergoing elective operation were randomly divided into 3 groups with 3 subgroups each,and propofol,midazolam,etomidate were administered by bolus injection at propofol 1.5,2,3mg/kg, midazolam 0.2,0.3,0.4mg/kg, etomidate 0.15,0.3,0.4mg/kg accordingly. SLSEP was recorded before,during and after injection. Result:Propofol did not significantly change the latencies of the subcortical N_(14),cortical N_(20) and central conduction time(CCT)N_(14)-N_(20),decreased the interwave amplitude N_(20)-P_(25)(P
