Abstract

Objectives: To find out if renal resistive index (RRI) is altered early in the course of posttraumatic hemorrhage and if it may be a surrogate marker of silent hypoperfusion and, in turn, hemorrhagic shock in polytrauma patients presenting to the emergency department (ED).

Methods: A prospective single-center cross-sectional study was conducted on 195 patients presenting to the ED with hemodynamically stable polytrauma. The patients were evaluated according to the extended-focused assessments with sonography for trauma (e-FAST) protocol and then underwent RRI measurement using Doppler ultrasonography (US). Measurements were performed by an ED physician with a minimum of 4 years' experience in ED practice and USG examination, plus a certification to perform basic and advanced US training. The primary outcome was the development of hemorrhagic shock according to the American College of Surgeons Advanced Trauma Life Support (ATLS) hemorrhagic shock classification. The secondary outcome was the diagnostic performance of RRI in determining occult hemorrhage.

Results: A total of 84 patients (43.1%) developed hemorrhagic shock. There was a significant difference between the RRI levels of the groups with and without hemorrhagic shock (P < .05). While most of the patients with a mean RRI of <0.05 did not develop hemorrhagic shock, to the contrary, patients with a mean RRI of >0.07 mainly developed hemorrhagic shock. When we used the RRI value as a diagnostic test to detect patients who developed hemorrhagic shock, the area under the curve value was 0.832 (P < .001).

Conclusion: RRI can be a promising noninvasive, early marker of silent hemorrhage.

肾阻力指数对血流动力学稳定型多发外伤患者隐匿性出血的预测价值。
目的:了解肾抵抗指数(RRI)是否在创伤后出血的早期发生改变,以及它是否可以作为无症状灌注不足的替代指标,进而作为急诊多发创伤患者失血性休克的替代指标。方法:对195例就诊于急诊科的血流动力学稳定的多发创伤患者进行前瞻性单中心横断面研究。根据创伤超声扩展聚焦评估(e-FAST)方案对患者进行评估,然后使用多普勒超声(US)测量RRI。测量由具有至少4年ED实践经验和USG检查经验的ED医生进行,并具有执行基本和高级美国培训的认证。根据美国外科医师学会高级创伤生命支持(ATLS)失血性休克分类,主要结局是失血性休克的发展。次要结果是RRI在确定隐匿性出血方面的诊断性能。结果:84例患者(43.1%)发生失血性休克。失血性休克组与非失血性休克组RRI水平差异有统计学意义(P < 0.07),以失血性休克为主。当我们用RRI值作为诊断指标来检测失血性休克患者时,曲线下面积为0.832 (P)。结论:RRI是一种有希望的无创、无症状出血的早期标志物。

期刊介绍: The Journal of Ultrasound in Medicine (JUM) is dedicated to the rapid, accurate publication of original articles dealing with all aspects of medical ultrasound, particularly its direct application to patient care but also relevant basic science, advances in instrumentation, and biological effects. The journal is an official publication of the American Institute of Ultrasound in Medicine and publishes articles in a variety of categories, including Original Research papers, Review Articles, Pictorial Essays, Technical Innovations, Case Series, Letters to the Editor, and more, from an international bevy of countries in a continual effort to showcase and promote advances in the ultrasound community. Represented through these efforts are a wide variety of disciplines of ultrasound, including, but not limited to: -Basic Science- Breast Ultrasound- Contrast-Enhanced Ultrasound- Dermatology- Echocardiography- Elastography- Emergency Medicine- Fetal Echocardiography- Gastrointestinal Ultrasound- General and Abdominal Ultrasound- Genitourinary Ultrasound- Gynecologic Ultrasound- Head and Neck Ultrasound- High Frequency Clinical and Preclinical Imaging- Interventional-Intraoperative Ultrasound- Musculoskeletal Ultrasound- Neurosonology- Obstetric Ultrasound- Ophthalmologic Ultrasound- Pediatric Ultrasound- Point-of-Care Ultrasound- Public Policy- Superficial Structures- Therapeutic Ultrasound- Ultrasound Education- Ultrasound in Global Health- Urologic Ultrasound- Vascular Ultrasound
