Abstract:
Objective To observe effect of lidocaine pretreatment to malondialdehyde(MDA) and endothelin(ET) of patient ac-cepeted brain tumor removing and discuss the optimized pretreatment time .Methods 60 brain tumor patients in the hospital from March 2009 to September 2011 .according to the different pretreatment time ,the patients were randomly divided into five groups :group A(preoperative 48 h) ,group B(preoperative 24 h) ,group C(preoperative 12 h) ,group D(0 h or anesthesia induced) ,group E (control group) and group F(blank control group) ,10 cases in each group .Group A ,B ,C ,D with 1% lidocaine 1 .5 mg/kg intrave-nous pretreatment on schedule ,then induced conventional anesthesia ;group E were supplemented with 1% lidocaine 2 .5 mg · kg -1 · h-1 intravenous injection after anesthesia induction ;group F was performed routine program without lidocaine .The spontaneous breathing time ,awake time and tracheal extubation time was recorded ,while NIHSS score for evaluation of neural function defect was applied ,and peripheral serum level of MDA and ET was detected by colorimetric technique and radio-immunity .Results In group C ,the spontaneous breathing time ,awake time and tracheal extubation time were shorter than other groups ,but the difference had no statistically significant(P>0 .05) .There was no significant difference among each group in the aspect of NIHSS score 1 day before surgery(P>0 .05) ,after 14 days of operation ,NIHSS of group C was statistically lower than that of group E and group F (P<0 .05) .Before anesthesia induction ,there was no significant difference among groups (P> 0 .05) .MDA and ET content in group C was significantly lower than those in other groups after surgery (P<0 .05) .Conclusion Lidocaine given 12 h before cere-bral ischemia has varying degree protection against cerebral ischemia-reperfusion injury .The protection has relation with the de-crease of MDA and ET content .
