Prospective study on cardiopulmonary bypass prime reduction and its effect on intraoperative blood product and hemoconcentrator use.

Purpose: Evaluate the feasibility and clinical significance of crystalloid prime reduction during the initiation of cardiopulmonary bypass (CPB) using a modified bridge on the cardioplegia delivery system.

Methods: Prospective trial of crystalloid prime reduction using a standard Duraflow-coated CPB circuit and Vanguard 2:1 cardio plegia delivery system. Standard prime volume was 1500 cc of Plasmalyte.

Peripheral cardiopulmonary bypass with modified assisted venous drainage and transthoracic aortic crossclamp: optimal management for robotic mitral valve repair.

The purpose of this study was to evaluate peripheral cardiopulmonary bypass (CPB) with modified assisted venous drainage (MAVD) and transthoracic aortic cross-clamping to maintain a bloodless surgical field, adequate myocardial protection, systemic flow and pressure during robotic surgical repair of the mitral valve. Peripheral CPB was established with a standard Duraflo-coated closed circuit with femoral arterial and venous cannulation. An additional 17 Fr wire-bound cannula was inserted into the right internal jugular vein and drainage rates of 200-400 mL/min were regulated using a separate roller-head pump.
