Protocol to monitor cardiac function and hemodynamics in septic rodents

Septic cardiomyopathy is associated with high mortality in septic patients, characterized by reversible systolic and diastolic dysfunction. It is essential to monitor cardiac function and hemodynamic changes in septic animals. Here, we present a protocol to monitor cardiac function and hemodynamics in septic rodents. We describe steps for performing cecal ligation and puncture on rodents to induce sepsis, acquiring two-dimensional echocardiographic and M-mode ultrasonic images, and assessing mean arterial pressure in septic animals. For complete details on the use and execution of this protocol, please refer to Zhang et al.1
