Japan: An innovative system to restore the heart's 💞circulatory function within 3 minutes of its stopping!!

Scientists from a Japanese university announced the development of a system capable of resuming blood circulation to the heart within three minutes of it stopping.

According to a team from Tohoku University in Japan, the inspiration to create such a system came from the fatal shooting of former Japanese Prime Minister Shinzo Abe in July 2022.

The team said the system is designed to provide assistance in emergency situations such as terrorist attacks and other public emergencies.

According to a report published by Japanese news agency Jiji Press, the system was developed by Yasuyuki Shiraishi, an associate professor at the university's Institute of Development, Aging and Cancer, and members of his team.

“If we can control the bleeding and perform an emergency thoracotomy (an operation in which the chest wall is opened to view the internal chest organs), there is a chance to save the patient’s life,” the team said in announcing the innovative system.

The system is designed to enable blood circulation to resume within three minutes, with medical staff dividing tasks to secure the patient's airway, perform emergency thoracotomy, and administer blood transfusions.

While emergency resuscitation and intubation are being applied, doctors simultaneously install an artificial pump by puncturing the left ventricle of the heart, which supplies blood to the rest of the body.

Circulatory functions can be resumed by securing a blood transfusion route that connects the pump to the femoral artery.

The pump is then connected to the femoral artery to establish blood flow to restore circulatory function to the heart. In scenarios where communication via the femoral artery is difficult due to the location of the injury, the system calls for an alternative method.

Moreover, the system also allows the addition of an artificial lung for those cases where there is a lung injury.

“The window to prevent brain death after circulatory arrest is only three minutes,” the research team stated, according to the report. “A system that can resume circulation within this time frame is critical. In emergency situations, faster methods than these we have now remain ineffective.” practical".

"If this system is implemented, it could significantly increase the number of patients saved," the team said.
