Objective: This study was designed to explore the teaching self-efficacy, by clinical preceptors instructing sonography students, in bachelor’s degree-accredited sonography programs. Materials and Methods: A survey was provided to sonography clinical preceptors, to gauge their level of teaching self-efficacy. The survey instrument, Sonography Preceptor Teaching Self-Efficacy Inventory (SPTSEI) was used. The intent of the survey was to gauge, holistically, sonography preceptors’ perceptions of influencing student learning, in a clinical setting. Results: The survey respondents suggested that they had a high level of confidence in their skill to transmit knowledge and abilities to students. However, it was found that preceptors who had received some type of professional development, as preceptor, had a statistically significant higher level of teaching self-efficacy than those who had not received any type of training. Conclusion: Clinical preceptors are skilled health care professionals in their chosen discipline but may have little to no teaching experience. If preceptors do not fully understand their role in the educational process, both they and their students may not attain educational goals. It is therefore critically important that proper training and education, to support clinical preceptors, be provided for them. This survey would suggest that clinical preceptors, with training, can better perform their educational roles and better handle any challenges that might arise, as a part of providing clinical education.

Objective: This study was designed to use sonography and evaluate arteriovenous fistulas (AVFs) in dialysis patients. The aim was to determine criteria for distinguishing between patent AVFs with proper function (healthy) and unhealthy AVFs. Materials and Methods: This study enrolled 106 dialysis patients with an AVF. All fistulas were evaluated using spectral Doppler and grayscale sonography, assessing parameters such as draining vein diameter, distance of the venous vein from the skin surface, feeding artery diameter, presence of thrombosis, and fistula stenosis. Subsequently, Doppler criteria such as flow volume (FV) and resistance index (RI) were measured and compared between healthy and unhealthy AVFs. Results: This cohort’s spectral Doppler findings demonstrated lower FV and higher RI, in unhealthy AVFs, compared to healthy ones (283.5 ± 101.26 mL/min vs 1383.43 ± 756.76 mL/min; P = .006) and (0.55 ± 0.33 vs 0.37 ± 0.14; P = .004) respectively. Conclusion: The spectral Doppler and grayscale sonographic imaging made it possible to evaluate AVF performance and determine its quality. In this cohort, a decreased FV, increased RI, and decreased draining vein diameter were observed in unhealthy AVFs. These results would suggest that sonographers and clinicians should pay close attention to these parameters when assessing the function of an AVF, for patients undergoing hemodialysis.
目的:应用超声技术评价透析患者的动静脉瘘(avf)。目的是确定区分功能正常(健康)的专利avf和不健康的avf的标准。材料和方法:本研究纳入106例AVF透析患者。所有瘘管均采用频谱多普勒和灰度超声进行评估，评估引流静脉直径、静脉与皮肤表面的距离、供血动脉直径、血栓形成情况和瘘管狭窄等参数。随后，测量多普勒标准，如流量(FV)和阻力指数(RI)，并比较健康和不健康avf之间的差异。结果:该队列的频谱多普勒结果显示，与健康的avf相比，不健康的avf的FV较低，RI较高(283.5±101.26 mL/min vs 1383.43±756.76 mL/min;P = 0.006)和(0.55±0.33 vs 0.37±0.14;P = .004)。结论:超声多普勒和灰度成像技术可以评价AVF的性能，确定其质量。在这个队列中，在不健康的avf中观察到FV降低、RI增加和引流静脉直径减小。这些结果提示超声医师和临床医生在评估血液透析患者的AVF功能时应密切关注这些参数。
