Clinical Trial Summary

Establish and verify the feasibility and effectiveness of VA-ECMO remote limb re-perfusion monitoring technology.

Description:

It is proposed to monitor VA-ECMO arterial end side branch circulation in real time through a set of monitoring equipment, guide clinical adjustment, improve lower limb re-perfusion, reduce the occurrence of lower limb ischemia, in order to achieve the goal of early detection, early prevention and early treatment, and provide reference and theoretical basis for clinical practice.

Monitoring techniques are divided into two parts: A. monitoring equipment (connecting transdiotic monitoring pressure on va-ECMO side branches cycle); B.to guide clinical adjustment by monitoring pressure (average arterial pressure).

• signed ECMO informed consent;

• femur vein VA-ECMO treatment;

• agreed to establish VA-ECMO side branch cycle;

• informed consent to this study.

Related Conditions & MeSH terms

• Perfusion; Complications

Intervention

Behavioral:
• Closed transdyser
When the average arterial pressure = 50mmHg, it is indicated that the basic blood supply of the lower extremities is satisfied without special treatment, and when the average arterial pressure < 50mmHg, it indicates insufficient perfusion, by adjusting the pipe position, changing the ECMO flow rate, and properly clamping the artery end to divert part of the blood flow to the side branch circulation, so that the average arterial pressure is maintained above 50mmHg.
• Routine monitor
Obtain oxygen saturation, skin color, temperature, etc
