摘要
目的研究脊柱侧凸病人体质量、身高、年龄与术中体感诱发电位(SEP)监护的关系。方法以70例脊柱侧凸病人为对象,其中男性19例,女性51例;年龄4～35岁,平均年龄17.5岁;身高100～188cm,平均159.44cm;体质量15.5～84kg,平均44.39kg。分析术中皮层和下皮层SEP的潜伏期和波幅在不同手术阶段的百分比变化率与体质量、身高、年龄的相关性。结果数据统计结果显示,各监护阶段SEP波峰潜伏期和波幅的百分比变化率与病人的体质量、身高和年龄没有显著的相关性(相关系数│r│<0.35,P>0.05)。结论在脊柱侧凸矫形手术术中脊髓监护过程中,病人的身高、体质量和年龄不会对SEP监护结果产生影响。
Objective To study the relationship of body height,weight and age with the intraoperative somatosensory evoked potential （SEP） monitoring. Methods Seventy scoliosis patients undergoing spinal surgery were enrolled into this study. The variation rate of latencies and wave amplitudes from both cortical and sub-cortical SEP at different surgical stages were analyzed to evaluate their correlations with body height, weight and age. Results Lower correlation coefficients （｜r｜ 〈 0.35） suggested that there was little effect of body height, weight and age on intraoperative SEP monitoring outcomes. The statistic analysis did not find any significant relationship between body height, weight and age with SEP latency/wave amplitude changes （P 〉 0.05）. Conclusion During the SEP monitoring of scoliosis surgery, there would be no effects of body height, weight and age on monitoring outcomes.
