Development of the new measurement method using the time resolved spectroscopy for the acute abdominal disease

本研究的目的是开发一种新的用于急腹症的时间分辨光谱(TRS)测量方法。在猪低氧血症或心脏骤停时，用放置在体表的TRS监测肝脏和肠道的Hb浓度和组织氧合情况。接下来进行手术，在腹壁和肝脏、肠道之间插入遮阳板，并进行类似的实验(减少FiO2或心脏骤停)。我能够证实，通过使用TRS从人体表面进行新的测量，可以非侵入性地测量肝脏和肠道的组织氧合。

The purpose of this study is the development of the new measurement using the time-resolved spectroscopy (TRS) for the acute abdominal disease. The Hb concentration and tissue oxygenation in the liver and intestinal tracts were monitored by the TRS, which probes put on a surface of the body and fixedit, during reduction of FIO2 or cardiac arrest in the pig model. An operation was performed next and a shade board was inserted between the abdominal wall and liver, intestinal tracts, and similar experiments (reduction of FIO2 or cardiac arrest) were carried out. I was able to confirm that the tissue oxygenation in the liver and intestinal tracts could be measured noninvasively by the new measurement using TRS from a surface of a body.
