The assessment of the body fluid status is one the most challenging tasks in clinical practice. Although there are many methods to assess the body fluid status of patients, none of them is fully satisfactory in contemporary medical sciences. In the article below, we compare the results of measurements performed by experienced and inexperienced examiners based on the inferior vena cava/aorta diameter index in a sonographic hydration assessment. The study enrolled 50 young students at the age of 19-26 (the median age was 22.95) including 27 women and 23 men. The volunteers were examined in the supine position with GE Logiq 7 system and a convex transducer with the frequency of 2-5 MHz. The measurements were performed in the longitudinal and transverse planes by two inexperienced examiners - the authors of this paper, following a four-hour training conducted by an experienced sonographer. The longitudinal values of the inferior vena cava/aorta diameter index obtained in this study were similar to those found in the literature. The reference value for the inferior vena cava/aorta index determined by Kosiak et al., which constituted 1.2 ± 2 SD, for SD = 0.17, was similar to the values obtained by the authors of this paper which equaled 1.2286 ± 2 SD, for SD = 0.2. The article presented below proves that measuring the inferior vena cava/aorta diameter index is not a complex examination and it may be performed by physicians with no sonographic experience. Furthermore, the paper demonstrates that the inferior vena cava/aorta diameter index measured in the transverse plane is similar to the inferior vena cava/aorta diameter index determined in the longitudinal plane. Thus, both measurements may be used interchangeably to assess the hydration status of patients.
评估体液状态是临床实践中最具挑战性的任务之一。尽管有许多方法可用于评估患者的体液状态，但在当代医学科学中，没有一种方法能完全令人满意。在下文，我们比较了经验丰富和缺乏经验的检查者在超声水化评估中基于下腔静脉/主动脉直径指数所进行测量的结果。该研究招募了50名年龄在19至26岁之间的年轻学生（中位年龄为22.95岁），其中包括27名女性和23名男性。志愿者们在仰卧位使用GE Logiq 7系统和频率为2 - 5 MHz的凸阵探头进行检查。由本文作者这两位缺乏经验的检查者在经过经验丰富的超声检查医师四小时培训后，在纵向和横断面上进行测量。本研究中获得的下腔静脉/主动脉直径指数的纵向值与文献中所发现的值相似。Kosiak等人确定的下腔静脉/主动脉指数的参考值为1.2 ± 2 SD（SD = 0.17），与本文作者所获得的值相似，本文作者所获值为1.2286 ± 2 SD（SD = 0.2）。下文的文章证明，测量下腔静脉/主动脉直径指数并非一项复杂的检查，没有超声检查经验的医生也可以进行。此外，该论文表明，在横断面上测量的下腔静脉/主动脉直径指数与在纵断面上确定的下腔静脉/主动脉直径指数相似。因此，两种测量方法均可交替使用以评估患者的水化状态。
