Abstract

Background: A drain is often placed in the abdominal cavity for postoperative monitoring and early detection of complications such as rebleeding and pancreatic or bile leaks. Since determining the color of the drainage fluid is subjective, an objective method of judging color is needed.

Methods: The hemoglobin concentration of the drainage fluid after gastrointestinal surgery was measured using the Hemato Check Module, a newly developed instrument capable of absorbance analysis with an optical sensor. The correlation between the results and those measured by an existing blood count measuring device (XN3000) was investigated.

Results: A total of 215 specimens were analyzed in 43 patients. For the correlation analysis, there was a strong positive correlation with a correlation coefficient of 0.884 (P < 0.001). The Hemato Check Module showed a clear proportional error compared to the XN3000.

Conclusion: The Hemato Check Module was a convenient and accurate instrument for measuring hemoglobin concentration in waste fluid to determine the presence of blood.

光学传感器吸收分光光度法评价术后引流液中血红蛋白浓度。

背景:通常在腹腔内放置引流管，用于术后监测和早期发现并发症，如再出血和胰腺或胆汁泄漏。由于确定引流液的颜色是主观的，因此需要一种客观的判断颜色的方法。方法:采用新开发的光学传感器吸光度分析仪器Hemato Check Module检测胃肠道术后引流液血红蛋白浓度。研究结果与现有血球计数测量仪(XN3000)测量结果的相关性。结果:43例患者共分析标本215份。相关性分析显示，两者呈正相关，相关系数为0.884 (P < 0.001)。与XN3000相比，Hemato Check Module显示出明显的比例误差。结论:血色素检测模块是一种简便、准确的废液血红蛋白浓度检测仪器。

期刊介绍： Yonago Acta Medica (YAM) is an electronic journal specializing in medical sciences, published by Tottori University Medical Press, 86 Nishi-cho, Yonago 683-8503, Japan. The subject areas cover the following: molecular/cell biology; biochemistry; basic medicine; clinical medicine; veterinary medicine; clinical nutrition and food sciences; medical engineering; nursing sciences; laboratory medicine; clinical psychology; medical education. Basically, contributors are limited to members of Tottori University and Tottori University Hospital. Researchers outside the above-mentioned university community may also submit papers on the recommendation of a professor, an associate professor, or a junior associate professor at this university community. Articles are classified into four categories: review articles, original articles, patient reports, and short communications.
