The following abstracts were presented at the Autumn Meeting of the Association of Cardiothoracic Anaesthetists in Cambridge, June 2007 The influence of mannitol on the volume of fluid given to adult patients during cardiopulmonary bypass

摘要

During cardiopulmonary bypass, non-blood fluids are added to the circulation via the priming of the circuit. There is no standardisation of priming fluids between different cardiac centres, but most use a mixture of crystalloid and colloid. Mannitol, an osmotic diuretic, is often used in the prime with the aim of minimising renal damage. Although mannitol has no effect on renal function we have noticed that it reduces the amount of additional fluid given to maintain reservoir volume. This study aims at examining the effects of mannitol on fluid balance during cardiopulmonary bypass.
