Despite decades of research, the mortality rate of sepsis and septic shock remains unacceptably high. Delays in diagnosis, identification of an infectious source, and the challenge of providing patient-tailored resuscitation measures routinely result in suboptimal patient outcomes. Bedside ultrasound improves a clinician's ability to both diagnose and manage the patient with sepsis. Indeed, multiple point-of-care ultrasound (POCUS) protocols have been developed to evaluate and treat various subsets of critically ill patients. These protocols mostly target patients with undifferentiated shock and have been shown to improve clinical outcomes. Other studies have shown that POCUS can improve a clinician's ability to identify a source of infection. Once a diagnosis of septic shock has been made, serial POCUS exams can be used to continuously guide resuscitative efforts. In this review, we advocate that the patient with suspected sepsis or septic shock undergo a comprehensive POCUS exam in which sonographic information across organ systems is synthesized and used in conjunction with traditional data gleaned from the patient's history, physical exam, and laboratory studies. This harmonization of information will hasten an accurate diagnosis and assist with hemodynamic management.
尽管经过了几十年的研究,脓毒症和感染性休克的死亡率仍然高得令人无法接受。诊断的延误、感染源的确定,以及提供针对患者的复苏措施的挑战,通常导致患者的治疗效果不理想。床边超声检查提高了临床医生诊断和处理脓毒症患者的能力。事实上,已经开发了多种即时护理超声(POCUS)方案来评估和治疗各种危重症患者。这些方案主要针对的是无法区分的休克患者,并且已经显示出可以改善临床结果。其他研究表明,POCUS 可以提高临床医生识别感染源的能力。一旦诊断出感染性休克,就可以连续进行 POCUS 检查,以持续指导复苏治疗。在这篇综述中,我们主张对疑似脓毒症或感染性休克的患者进行全面的 POCUS 检查,其中跨器官系统的超声信息被综合,并与从患者的病史、体检和实验室研究中收集的传统数据结合使用。这种信息的协调将加快准确的诊断并有助于血流动力学管理。
