To validate a transit time ultrasound flowmeter (CardioMed CM 4000) for measuring blood flow in isolated colonic mesenteric arteries.
Experimental and clinical study.
Teaching hospital, Denmark. ANIMALS AND SUBJECTS: One female pig, and 6 patients being operated on for carcinoma of the sigmoid colon and rectum.
Volume blood flow measured by Cardiomed CM 4000 and pump withdrawal flow recordings.
Correlation between the two methods.
There was good agreement between transit time flow recordings and pump withdrawal flow recordings (correlation coefficient of 1.0). Of the differences between the two methods, 95% were between -0.16 ml min(-1) and 1.29 ml min(-1), mean 0.57 ml min(-1), or (in percentages) 105, 95% lying between 97-115. There was also good reproducibility in transit time flow recordings, the mean difference between repeated measurements being 0.06 ml min(-1), 95% lying between -0.66 ml min(-1) and 0.78 ml min(-1).
Ultrasound transit time flow recordings gave precise measurements of blood flow in isolated colonic mesenteric arteries.
验证一种经颅时间超声流量计（CardioMed CM 4000）用于测量离体结肠系膜动脉血流的有效性。
实验与临床研究。
丹麦的教学医院。
1只雌性猪以及6例因乙状结肠癌和直肠癌接受手术的患者。
采用Cardiomed CM 4000测量血流容积以及泵抽血流记录。
两种方法之间的相关性。
经颅时间血流记录与泵抽血流记录之间具有良好的一致性（相关系数为1.0）。两种方法的差异中，95%在-0.16毫升/分钟至1.29毫升/分钟之间，平均为0.57毫升/分钟，或以百分比计，95%在97 - 115之间。经颅时间血流记录也具有良好的可重复性，重复测量之间的平均差异为0.06毫升/分钟，95%在-0.66毫升/分钟至0.78毫升/分钟之间。
超声经颅时间血流记录能精确测量离体结肠系膜动脉的血流。
