Methods for evaluating intestinal ischemia include standard clinical criteria, Doppler ultrasonography, and intravenous fluorescein injection. Each has disadvantages, and a combination of methods is often used. The purpose of this study was to determine whether surface oximetry could be used to assess perfusion in an animal whose intestinal diameter approximates that of infants. Reversible arterial, venous, and arteriovenous occlusion was studied in rabbit intestines. After 6 to 8 hours of occlusion, intestinal vascularity was evaluated by the four methods listed. Doppler ultrasonography and surface oximetry were found to be unreliable tools for assessing perfusion in this animal model. We conclude that standard clinical criteria and fluorescein remain the standards for intraoperative evaluation of intestinal perfusion.
评估肠道缺血的方法包括标准临床标准、多普勒超声检查和静脉注射荧光素。每种方法都有缺点，因此常常联合使用多种方法。本研究的目的是确定表面血氧测定法是否可用于评估肠道直径与婴儿相近的动物的灌注情况。在兔肠中研究了可逆性动脉、静脉和动静脉阻塞情况。阻塞6至8小时后，采用列出的四种方法评估肠道血管情况。结果发现，在该动物模型中，多普勒超声检查和表面血氧测定法是评估灌注情况的不可靠工具。我们得出结论，标准临床标准和荧光素仍然是术中评估肠道灌注的标准方法。
