Abstract
PPV has been shown to be a better index of fluid responsiveness than SPV in CABG patients, and both were far superior to CVP and PAOP. The aim of this study is to investigate the usefulness of PPV to predict fluid responsiveness and to guide fluid therapy in patients undergoing aortic surgery with total circulatory arrest. We studied 34 adult patients undergoing aortic surgery with total circulatory arrest. PPV was calculated manually, SVI and CI were determined by transoesophageal echocardiography after weaning from the CPB as a baseline reading then after administration of 500cc ringer then another one after 15 minutes. Also CVP and PASP were measured
