Abstract
Fluid responsiveness is defined as an increase in stroke volume by 10% to 15% after infusion of 500 ml crystalloid over 10 min to 15 min. The wide application of point-of-care ultrasound in the operating room makes it possible to evaluate fluid responsiveness by ultrasound. Transthoracic echocardiography (TTE) examination is noninvasive, while trans-esophageal echocardiography (TEE) is minimally invasive. During the perioperative period, TEE can monitor fluid responsiveness in a dynamical, real-time, and continuous manner, with stable quality of images. The review is to summarize the ultrasound indicators that can predict fluid responsiveness, including respiratory-pulse parameters, respiratory variation of the vein, parameters related to cardiac diastole function, and fluid responsiveness tests, so as to provide comprehensive understanding.
Key words:
Fluid responsiveness; Trans-esophageal echocardiography; Respiratory variation of the vein; Stroke volume variation
