In 43 patients serial SSER recordings were made during operations for the clipping of arterial aneurysms of cerebral vessels performed under controlled arterial hypotension. SSER recordings during the preliminary phase of the operation showed an average decrease in the response amplitude of 20% during trepanation and a reduction (by 23% of the initial value) during the phase of arterial hypotension. The response recovered to 84% of its initial level by the moment of the beginning of the operation. There was no statistically significant relationship between serial SSER parameter values during arterial pressure reduction and the duration or degree of hypotension. The results testify to the higher information content of such SSER parameters as the amplitude of the first positive complex, as compared with latency criteria and in particular the CCT. It has also been found that a significant increase in the information value of the SSER for the evaluation of ischemia effect on the brain function may be obtained by synchronous stimulation of both arms and registration of cortical responses from both hemispheres.
在43例患者中，于控制性动脉低血压下行脑血管动脉瘤夹闭手术期间进行了系列体感诱发电位（SSER）记录。手术初始阶段的SSER记录显示，颅骨钻孔时反应幅度平均下降20%，动脉低血压阶段反应幅度下降（降至初始值的23%）。到手术开始时，反应恢复至初始水平的84%。动脉压降低期间系列SSER参数值与低血压持续时间或程度之间无统计学显著关系。结果表明，与潜伏期标准尤其是中枢传导时间（CCT）相比，首个正复合波幅度等SSER参数具有更高的信息量。还发现，通过双侧上肢同步刺激并记录双侧半球的皮质反应，可显著提高SSER在评估缺血对脑功能影响方面的信息价值。
