AI Technical Summary
Traditional cardioplegia systems in heart/lung machines use large volumes of crystalloid solutions, leading to hematocrit concentration drops and complications that require hemoconcentration or packed red blood cells, which can cause additional issues during open-heart surgery.
A microplegia delivery system using syringe pumps to directly administer cardioplegia agents into the blood-carrying portion of the cardioplegia circuit, allowing precise control of drug delivery without crystalloid dilution, with coordinated flow rates linked to real-time blood flow rates and adjustable drug-to-blood ratios.
Minimizes the amount of cardioplegia agents used, maintains blood concentration, and allows for efficient delivery of short half-life medications close to the surgical site, reducing complications and enhancing medication efficacy.
