Use of Vasopressin in Patients at High Risk of Acute Kidney Injury Admitted to the ICU: a Feasibility Randomized Clinical Trial

Обзор

Renal dysfunction is a frequent complication in patients admitted to intensive care units (ICUs), associated with high morbidity and mortality. Current therapeutic options to prevent this condition are limited and lack robust scientific evidence. This pilot study consists of a multicenter, blinded, randomized clinical trial, unprecedented in the literature to date, aiming to fill this knowledge gap and offer new therapeutic perspectives to improve renal outcomes in critically ill patients admitted to the ICU.

Подробное описание

This is a multicenter, placebo-controlled, double-blind, randomized feasibility clinical trial with a proposal to include 60 patients across 3 to 4 research centers.

This study will be conducted in Brazilian hospitals, covering both public and private healthcare profiles across various states of Brazil. Most of these hospitals are academic and teaching institutions, ensuring a wide diversity of data and perspectives for the research.

The objective of this study is to assess the feasibility of conducting a larger subsequent trial to analyze whether the use of vasopressin in patients prone to developing acute kidney dysfunction after admission to intensive care units (ICUs) can prevent the condition (acute kidney dysfunction).

This study is based on the null hypothesis (H0) that there will be no significant difference in the development of acute kidney injury between the group treated with vasopressin and the control group, while the alternative hypothesis (H1) proposes that the administration of vasopressin may reduce the risk of acute kidney injury in high-risk patients admitted to ICUs. The primary objective is to evaluate the feasibility of the study, specifically adherence to the established protocol and the monitoring of potential adverse effects during its conduct.

Вмешательства

• Препарат Vasopressin
  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
• Другое 0,9% saline solution
  Similar to the intervention protocol, but using a placebo composed of 0.9% saline solution.
