重症超声在呼吸机撤离中的应用进展和展望

Application progress and prospect of critical care ultrasound in weaning process

脱机困难在危重症患者中很常见,长时间机械通气及脱机失败均会影响患者的临床结局,如何更好地促成和达成呼吸机的尽早撤离(脱机),是非常重要的课题。重症超声作为重要结构、功能、形态的多维监测手段,可对心脏、肺、膈肌等重要环节的状态和储备能力进行全方位的评估,有助于提升对呼吸环路中核心环节的了解和掌握,在脱机评估及导向治疗中具有重要价值。该文将对重症超声在脱机过程中的应用进行综述。

Weaning difficulty is common in critically ill patients.Prolonged mechanical ventilation and weaning failure adversely affect the clinical outcome.How to better promote and achieve the early extubation is a very important subject.As a multi-dimensional monitoring method of important structure,function and morphology,critical care ultrasound which is helpful to improve our understanding and grasp of the core links in the respiratory circuit can comprehensively evaluate the state and reserve capacity of some important organs,such as the heart,lungs and diaphragm.It has great value in assessment of weaning and guided treatment.This paper will review the application of severe ultrasound in weaning.
