Abstract:
Objective To determine the effects of different doses of cisatracurium on motor e-voked potential of neurosurgery operation.Methods Sixty patients,36 males and 24 females,aged 18 to 65 years,ASA physical status Ⅰ or Ⅱ,scheduled for spinal surgery with motor evoked potential monitoring,were included and randomly assigned to three groups.A single dose of cisatra-curium besilate for injection was given by intravenous injection in 5 s after the induction of general an-esthesia,respectively 0.1 mg/kg (group A),0.1 5 mg/kg (group B)and 0.2 mg/kg (group C).Cas-cade Elite 32 channel monitor was used to monitor MEPs,the electrode was stimulated for once two minutes after given the muscle relaxant,and the leading time of the wave of MEPs was recorded. Cooper’s score was used to evaluate the intubation conditions.Results The appearance time of the wave of motor evoked potentials was significantly longer in group C [(39.60±1.79)min]than that in groups A [(20.10 ± 1.89 )min]and B [(20.50 ± 1.93 )min](P < 0.05 ).The intubation conditions was significantly better in group B (100%)and C (100%)than that in group A (65%)(P<0.05).Conclusion The shortest time to elicit waveform of MEPs using the dose of cisatracurium is 0.1 5 mg/kg at induction of general anesthesia,which is better for tracheal intubation.The dose 0.1 5 mg/kg of cisatracurim is recommended as the initial dose on neurosurgery operation with motor e-voked potential monitoring.
