Angiotensin II for Post Cardiac Surgery Vasoplegia (ANGII_V) (ANGII_V)
2026年6月22日 更新者:Craig Ainsworth、Methodist Healthcare System of San Antonio
The goal of this study is to conduct a prospective trial implementing a modified version of the Emory Protocol for administering ANG II to patients with post cardiac bypass vasoplegia.
The main questions we aim to answer are: 1.) does administration of improve mortality, 2.) does the administration of Ang II using the modified protocol shorten the time needed to reach optimal MAP, 3.) does the administration of Ang II using the modified protocol shorten length of stay in the ICU and hospital?
Researchers will compare outcomes from the interventional group to historical controls who did not receive Ang II using the modified protocol.
研究概览
详细说明
Giapreza is a synthetic human Ang II treatment which acts as a RAAS pathway regulator to rais MAP in adults.
This will be a single center study comparing patients treated with a modified Emory protocol to historical controls who have not received Ang II.
We will observe the effects of using a modified version of the Emory protocol, which includes lowering the dosages needed for norepinephrine and vasopressin.
Additionally, clinicians will administer Ang II prior to starting methylene blue, a drug that poses more risk to patients than Ang II.
Using this modified version of this protocol, patients who have post cardiopulmonary bypass vasoplegia who are already on vasopressin 0.04 units/min, norepinephrine 0.1 mcg/kg/min will have Ang II initiated at 10 to 20 ng/kg/min and titrated by 10 ng/kg/min every 5 minutes to a maximum dose of 80 ng/kg/min.
If patients do not achieve their MAP goal of 65mmHg or greater within 3 hours, then they will have ANG II discontinued and will receive a dose of methylene blue at 2 mg/kg.
If the patients do not achieve their MAP goal with methylene blue then they will receive a cyanokit.

实验性的:Ang II Administration using a modified Emory protocol
Using this modified version of this protocol, patients who have post cardiopulmonary bypass vasoplegia who are already on vasopressin 0.04 units/min, norepinephrine 0.1 mcg/kg/min will have Ang II initiated at 10 to 20 ng/kg/min and titrated by 10 ng/kg/min every 5 minutes to a maximum dose of 80 ng/kg/min.
Case report forms (CRF) tracking MAP and dosage of drugs will be completed for each patient for up to 48 hours.

无干预:Evaluating Effectiveness of modified Emory Protocol on outcomes from vasoplegia after bypass
Historical controls will be extracted from EMR and selected based on 1:1 matching with patients in experimental arm.
Matching will be based on a number of factors.
Descriptive and comparative analyses will be conducted.
