IMPLICATIONS: We compared the influence of crystalloid/colloid versus crystalloid intravascular volume administration before spinal anesthesia on cardiac output using a thoracic electrical bioimpedance device. Volume preload with saline plus hydroxyethyl starch prevented a decrease in cardiac output but did not prevent spinal-induced hypotension in elderly patients undergoing transurethral resection of the prostate.
