Dr. Shingo Ouchi, the head of the Department of Cardiovascular Surgery at Nakadori General Hospital in Japan, released a clinical report detailing how the Coaxial Drain helped avoid cardiac tamponade when unexpected major bleeding occurred during a CABG procedure.

After operating time had exceeded eight hours and other options were exhausted, Dr. Ouchi and his team decided to close the chest despite a large amount of bleeding. Aware that cardiac tamponade could occur, Dr. Ouchi placed a 19Fr Redax Smart Drain in the pericardium using Circular Pericardial Drainage (CPD) and a 24Fr Redax Coaxial Drain in the anterior mediastinum. The team closed the chest and left the pericardium open.

Table 1 shows the amount of bleeding both immediately after surgery and post-operatively.

Dr. Ouchi noted that the bleeding was primarily coming from the anterior mediastinum where the Coaxial Drain was placed. The Coaxial Drain did not clog and so cardiac tamponade did not occur. The Coaxial Drain was removed on day seven and there was no clogging in the removed Coaxial Drain.

Dr. Ouchi stated, “When postoperative CT showed almost no hematoma in the pericardium or anterior mediastinum, we could not help but feel that the CPD + anterior mediastinal Coaxial Drain combination was a very good one.”

Dr. Ouchi highlighted the effectiveness was due to the Coaxial Drain’s design. “The design combines the standard hole-type drain and slit-type drain so as to deliver the suction force to more distal portions of the device.”

“Though we did not expect to experience major bleeding in the course of the heart surgery, when the unexpected occurred, it was an opportunity to make use of the Coaxial Drain we had prepared just in case, and we can only take our hats off to the way it performed,” Ouchi stated.

Dr. Ouchi concluded that major bleeding was overcome using CPD and a Coaxial Drain during a CABG procedure. “The Coaxial offers efficient drainage and appears to be effective in cases where major bleeding is present.”

ABOUT THE REDAX COAXIAL DRAIN

The Redax Coaxial has a direct transition from the in-dwelling design to a single bore tube which increases flow and maintains patency. Competitive fluted catheters have an indirect transition spanning a few inches in which a bottleneck can occur in the middle of the catheter where it transitions from a fluted profile into a single bore tube. This bottleneck restricts flow and increases the likelihood of thrombus formation which leads to occlusion and increased incidence of retained blood in the thorax.  As recently documented in the JTD article, the Coaxial also proves to evacuate more fluid in a more rapid time as compared to conventional (“large bore”) chest tubes.
