Severe
patients with coronaviras
disease 2019 (COVID-19) are characterized by persistent
lung damage, causing
respiratory failure,
secondary circulatory changes and multiple organ dysfunction after
virus invasion. Because of its dynamic, real-
time, non-invasive, repeatable and other advantages, critical
ultrasonography can be widely used in the
diagnosis, assessment and guidance of
treatment for severe
patients. Based on the recommendations of
critical care experts from all over the country
who fight against the
epidemic in Wuhan, this article summarizes the guidelines for the
treatment of COVID-19 based on critical
ultrasonography, hoping to provide help for the
treatment of severe
patients. The recommendations mainly cover the following aspects (1)
lung ultrasound in
patients with COVID-19 is mainly manifested by thickened and irregular pleural lines, different types of B-lines, shred signs, and other consolidation like dynamic
air bronchogram; (2)
Echocardiography may show right
heart dysfunction, diffuse cardiac function enhancement,
stress cardiomyopathy, diffuse cardiac
depression and other
multiple abnormalities; (3) Critical
ultrasonography helps with initiating early
treatment in the suspect
patient,
screening confirmed
patients after
intensive care unit admission, early assessment of sudden critical events, rapid grading assessment and
treatment based on it; (4) Critical
ultrasonography helps to quickly screen for the
etiology of
respiratory failure in
patients with COVID-19, make
oxygen therapeutic strategy, guide the implementation of
lung protective
ventilation, graded management and precise off-
ventilator; (5) Critical
ultrasonography is helpful for assessing the circulatory status of
patients with COVID-19, finding chronic cardiopulmonary
diseases and guiding
extracorporeal membrane oxygenation management; (6) Critical
ultrasonography contributes to the management of organs besides based on cardiopulmonary
oxygen transport; (7) Critical
ultrasonography can help to improve the success of operation; (8) Critical
ultrasonography can help to improve the
safety and quality of
nursing; (9) When performing critical
ultrasonography for
patients with COVID-19, it
needs to implement three-level
protection standard, pay
attention to disinfect the machine and strictly obey the rules from
nosocomial infection. (10)
Telemedicine and
artificial intelligence centered on critical
ultrasonography may help to improve the
efficiency of
treatment for the
patients with COVID-19. In the
face of the global spread of the
epidemic, all we can do is to share experience, build a defense line, We
hope this recommendations can help COVID-19
patients therapy.
