Abstract

We have used laser Doppler flowmetry to assess human colonic blood flow in patients with healthy mucosa and in those with active proctitis. We report a significant correlation between colonic serosal laser Doppler flux readings and serosal tissue oxygen tension (n = 45: r = 0.671: p = 0.001). Mucosal blood flow was measured using the PF309 probe of a Perimed Pf2b set on 12 kHz frequency shift. There was no significant difference throughout the colon in healthy patients. The flow in rectal mucosa was significantly higher in patients with proctocolitis than in normal mucosa.

摘要

我们使用激光多普勒血流仪评估了健康黏膜患者和活动性直肠炎患者的人体结肠血流情况。我们报告称，结肠浆膜激光多普勒通量读数与浆膜组织氧张力之间存在显著相关性（n = 45：r = 0.671：p = 0.001）。使用设置在12 kHz频移的Perimed Pf2b的PF309探头测量黏膜血流。在健康患者的整个结肠中，血流情况没有显著差异。直肠结肠炎患者直肠黏膜中的血流显著高于正常黏膜中的血流。
