Prospective double blind randomized controlled trial. By randomizing patients undergoing kidney transplantation into a conventional catecholamine drug (dobutamine) blood pressure maintenance group and a terlipressin-complexed dobutamine group, the investigators compared the effect of intraoperative blood pressure maintenance and the dosage of the vasoactive drug, postoperative graft function, delayed graft function, and other related complications between the two groups, in order to demonstrate whether the use of terlipressin for blood pressure regulation during kidney transplantation is superior to the existing treatments.
