| Frailty, a multisystem syndrome in which the decrease of physiological reserve leads to the decrease of anti-stress ability, is highly prevalent among the elderly and is closely associated with adverse outcomes in surgical patients. Therefore, it is necessary for anesthesiologists to evaluate frailty during perioperative period. However, how to quantify frailty quickly, accurately, and objectively remains a challenge. As the importance of muscle changes in the pathophysiological changes of frailty has been gradually revealed, bedside muscle ultrasound has attracted widespread attention in the assessment of weakness. This article introduces the parameters of bedside muscle ultrasoundand, the selection of parameters, and muscles for the assessment of frailty in elderly patients, which is expected to provide reference for anesthesiologists in assessing frailty during the perioperative period. |
