The cardiovascular responses and the effect on pulmonary shunt due to aortic cross-clamping and declamping were studied in 5 patients undergoing reconstructive infrarenal aortic surgery.
Prior to aortic cross-clamping enflurane was used for decreasing cardiac afterload. Prior to aortic declamping patients recieved plasmanate solution at a rate which maintained pulmonary artery occlusion pressure (PAOP) 3-5mmHg above pre-clamped values.
No significant changes in cardiovascular responses were seen due to clamping. Declamping produced little changes in cardiovascular responses and which were similar to the pre-declamped state.
No significant changes were seen on the pulmonary shunt during the operation.
