Key result
A novel cannula combination using a JELCO IV catheter, extension tube, and three-way stopcock achieved higher flow rates and significantly lower CPB circuit pressure than the Radifocus Introducer sheath.
Why the study?
Flow rate with the Radifocus Introducer sheath during pediatric CPB via femoral artery cannulation is limited by accessory parts having a smaller inner diameter.
Does a combination of a JELCO IV catheter, extension tube, and three-way stopcock improve flow rate and lower CPB circuit pressure compared to the Radifocus Introducer sheath in pediatric patients undergoing aortic arch repair?

A novel combination of a JELCO IV catheter, extension tube, and three-way stopcock provides higher flow rates and lower circuit pressures for femoral artery cannulation during pediatric aortic arch repair compared to standard sheaths.
May improve femoral CPB flow in pediatric arch repair; hypothesis-generating and requires prospective validation.
We previously presented a cardiopulmonary bypass (CPB) method with blood delivery via femoral artery cannulation for pediatric aortic arch repair operations using the Radifocus Introducer sheath. However, the flow rate with the Radifocus Introducer sheath is limited by accessory parts with the same structure having a smaller inner diameter among different sizes, rather than the sheath body. Therefore, we further devised a combination of the JELCO IV catheter, an extension tube, and a three-way stopcock with a larger opening to obtain more flow rate keeping the CPB circuit pressure significantly lower than when using the Radifocus Introducer sheath successfully.

Yamamoto et al. (2020) studied Pediatric aortic arch repair operations. Combination of JELCO IV catheter, extension tube, and three-way stopcock vs. Radifocus Introducer sheath was evaluated on Flow rate and CPB circuit pressure. A novel cannula combination using a JELCO IV catheter, extension tube, and three-way stopcock achieved higher flow rates and significantly lower CPB circuit pressure than the Radifocus Introducer sheath.
