Synthetic Angiotensin II/Giapreza in Pediatric Patients With Refractory Hypotension

The goal of this clinical trial is to determine the safety and efficacy of Angiotensin-II in the treatment of pediatric patients in fluid refractory vasodilatory shock. The main questions it aims to answer are: * To evaluate the change in blood pressure or reduction of vasoactive requirements (norepinephrine equivalent dosing) after initiating Angiotensin II * To establish the safety and tolerability of Angiotensin-II in pediatric patients Participants will receive Angiotensin-II in addition to standard of care therapy for vasodilatory shock. * The study team will then monitor the patient's vital signs, blood work, and for any potential side effects from the drug. * An ultrasound will be performed to look at blood flow through the kidney in the setting of vasodilatory shock. * A follow up phone call to check in with the patient will be performed 28 days after enrollment.

Efficacy and Safety of Angiotensin II Injection Versus Placebo in Patients With Refractory Distributed Shock

A randomized, double-blind, placebo-controlled study on the treatment of refractory distributed shock with angiotensin II injection, with a random ratio of 1:1. Assuming a success rate of 25% for the main therapeutic endpoint in the control group and 50% for the experimental group, a total of 214 subjects will be enrolled, including 107 in the experimental group and 107 in the control group.
