Use of Vasopressin in Patients at High Risk of Acute Kidney Injury Admitted to the ICU

"To dilute vasopressin, an ampoule containing 20 IU/ml (1 ml) of vasopressin will be used, which will be mixed with 100 ml of 0.9% physiological solution, resulting in a solution with a concentration of 0.2 IU/ ml. In this study, both central and peripheral vein infusion will be permitted.~The vasopressin administration protocol will consist of an initial dose of 0.02 IU/min (equivalent to 6 ml/h), which can be increased to 0.03 IU/min (9 ml/h) if the mean arterial pressure (MAP) is less than or equal to 65 mmHg. On the other hand, if MAP exceeds 90 mmHg, the dose can be reduced to 0.01 IU/min (3 ml/h). The minimum period for adjusting the drug dosage should be one hour."

Similar to the intervention protocol, but using a placebo composed of 0.9% saline solution.
