Serial measurements of global cerebral blood flow (CBF) were made in 15 patients undergoing elective neurosurgical procedures in the sitting position, using a modified intravenous 133Xenon technique. The mean supine CBF rose from 43 (+/-3) ml/100g/min to 62 (+/-6) ml/100g/min in the sitting position and remained elevated at the end of surgery at 62 (+/-5) ml/100g/min. Both increases in CBF were statistically significant with respect to baseline supine values.
采用改良的静脉注射133氙技术,对15例接受择期神经外科手术的坐位患者进行了全脑血流量(CBF)的连续测量。仰卧位时平均CBF为43(±3)ml/100g/分钟,坐位时升至62(±6)ml/100g/分钟,手术结束时仍维持在62(±5)ml/100g/分钟。CBF的这两次增加与仰卧位基线值相比均具有统计学意义。
