Summary A clinical study was undertaken to measure changes in systemic vascular resistance during cardiopulmonary bypass in 56 adults. Forty‐five patients snowed a rise in systemic vascular resistance and 77% required no inotropic support in the immediate post‐bypass period. Eleven of the 33 patients undergoing valve replacement surgery showed only a small increase or an actual decrease in systemic vascular resistance and required inotropic support. These results were statistically significant. Factors affecting cardiac performance are discussed.
