NCT ID: NCT05840432 Recruiting - Clinical trials for Postoperative Hypotension

Hypotension Prediction During Cardiac Surgery Postoperative Period

HPI-CCV
Start date: February 16, 2023
Phase:
Study type: Observational [Patient Registry]

The goal of this observational study is to learn about the performance of a new index for hypotension prediction during the immediate postoperative period of cardiac surgery patients in the intensive care unit. The main questions it aims to answer are: 1. Is this new index, Hypotension Prediction Index, able to predict hypotension during the immediate postoperative period in cardiac surgery patients in the intensive care unit? 2. How frequent hypotension is during the immediate postoperative period of cardiac surgery patients in the intensive care unit? Participants will not receive any treatment beyond the usual clinical practice during the study. All patients will have an invasive arterial line that is part of the usual clinical practice. This arterial line is connected to a pressure transducer for continuous measurement of arterial pressure. A transducer equipped with the necessary technology to calculate the hypotension prediction index will be used instead of the usual transducer. An echocardiogram will be performed in every patient in the study. This test is done frequently in patients after a cardiac surgery.

NCT ID: NCT05821647 Completed - Hypotension Clinical Trials

Hypotension Prediction 2 Study in Cardiac Surgery and Postoperative ICU Admission

HYPE-2
Start date: May 20, 2021
Phase: N/A
Study type: Interventional

This trial registration serves as an amendment incorporating the IPD Sharing Statement. This study already has a trial registration (2021 April 30) in the Netherlands Trial Registry (Reference number NL9449, https://trialsearch.who.int/). However, the NTR register is subject to a merger with another Dutch register. This means that existing registrations are still visible, but can no longer be adjusted. Study summary: Hypotension in the operating room (OR) and during post-operative ICU admission is common in surgical patients and even more prevalent in cardiac surgery patients. It is associated with adverse outcomes and while these events are preventable, current management is predominantly reactive. Edwards Lifesciences (Irvine, CA) has developed the Hypotension Prediction Index (HPI), an early warning system that predicts an hypotensive event, defined as MAP below 65 mmHg, with high accuracy minutes before it occurs. At the time of writing the protocol this model has not been tested in a clinical trial in cardiac surgery patients or ICU admitted patients. The aim of the HYPE-2 trial is to assess whether the HPI-algorithm can reduce the time-weighted average (TWA) of intra- and postoperative hypotension in elective on-pump coronary artery bypass graft (CABG) surgery patients.

NCT ID: NCT04529005 Completed - Shock Clinical Trials

Angiotensin II in the Perioperative Management of Hypotension in Kidney Transplant Recipients

Start date: August 13, 2020
Phase: Phase 4
Study type: Interventional

The current standard of catecholamine vasopressor management of perioperative hypotension in kidney transplant patients carries significant risks and falls short in many ways. Currently, there is an absence in the scientific literature and research describing the hemodynamic effectiveness and safety of novel pharmacologic agents such as angiotensin II (Giapreza - Ang II) in perioperative kidney transplant patients. Phase 3 registration trials have demonstrated the superior safety and efficacy of Ang II (Giapreza) in distributive shock patients compared to traditional vasopressor agents and the novel mechanism of action may provide additional protection in renal transplant patients. The pilot study entails giving informed and consenting kidney transplant recipients Ang II (Giapreza) as their first vasopressor if the need for vasopressors emerge either intraoperatively or postoperatively in kidney transplant recipients. The primary objective is to evaluate the safety and hemodynamic effects of Ang II (Giapreza) in the renal transplant population.
