NCT ID: NCT02652858 Completed - Cardiac Surgery Clinical Trials

Central and Peripheral Arterial Pressure Decoupling In Cardio-Pulmonary Bypass

CAPD-CPB
Start date: January 2016
Phase: N/A
Study type: Interventional

Central and peripheral arterial pressure decoupling occurs in some clinical conditions like sepsis or cardiopulmonary bypass. This decoupling may leed to unsuitable decisions such as the use of catecholamines. The aim of this study is to evaluate the pulse wave's speed as a marker of central and peripheral arterial pressure decoupling in a scheduled condition which is the cardiopulmonary bypass during cardiac surgery.

Evaluation Of The Pharmacokinetics Of Antithrombin III In Neonates And Infants Undergoing CPB And ECMO Support

Start date: June 2015
Phase: Phase 1
Study type: Interventional

The potential role of ATIII in achieving and maintaining adequate anticoagulation in pediatric patients on the heart-lung machine has recently taken on increased importance as caregivers strive to mitigate the risk for clinically significant clotting problems. It is known that ATIII levels are decreased in normal neonates and infants less than 6 months of age relative to older children and adults and become even further decreased in critically ill neonates and infants, including those with congenital heart disease. The current utilization of ATIII in the context of support on a heart-lung machine is based on pharmacokinetic data derived from adult subjects with congenital ATIII deficiency. There is a gap in knowledge as to the appropriate frequency of ATIII repletion, best method of monitoring, and mode of administration in critically ill neonates and infants receiving support on a heart-lung machine.Our long-term goal is to determine if antithrombin (ATIII) can effectively change the coagulation system in patients undergoing heart-lung machine support. The objective of this proposal, which is our first step in pursuit of that goal, is to determine the pharmacokinetics of ATIII in neonates and infants. Our central hypothesis is that ATIII will have different pharmacokinetic properties in neonates and infants than adults and these properties will be affected by the use of heart-lung machine. This research will result in critical data on the pharmacokinetics of ATIII in neonates and infants receiving heart-lung machine support. This contribution is significant because it is the first step in a continuum of research that is expected to lead to the development of a therapeutic strategy employing ATIII that will facilitate improved modulation of the coagulation cascade to prevent significant clotting and bleeding complications in pediatric patients requiring heart-lung machine support.

NCT ID: NCT02615262 Completed - Cardiac Surgery Clinical Trials

Intraoperative Dexamethasone in Pediatric Cardiac Surgery

Start date: December 2015
Phase: Phase 3
Study type: Interventional

Perioperative administration of steroids has been demonstrated to reduce systemic inflammatory response in infants undergoing cardiac surgery with cardiopulmonary bypass. However, data on effects of steroids on clinical outcomes are lacking. Hence the hypothesis of the present study: intraoperative administration of dexamethasone reduces complication rates and improves clinical outcomes in infants undergoing repair of congenital heart defects under cardiopulmonary bypass.

NCT ID: NCT02584868 Completed - Cardiac Surgery Clinical Trials

Colloids in Pediatric Cardiac Surgery: Comparison Between a Balanced and a Non-balanced Colloid

COLCHIRCARD
Start date: February 15, 2013
Phase: Phase 3
Study type: Interventional

This study will compare the clinical efficacy and safety of Volulyte® and Voluven® during elective open-heart surgery in pediatric patients.

NCT ID: NCT02566733 Completed - Clinical trials for Cardiopulmonary Bypass

Minto Model in Effect Site Mode for Target-Controlled Infusion of Remifentanil During Cardiopulmonary Bypass

Start date: October 2015
Phase: Phase 4
Study type: Interventional

Target controlled infusion with remifentanil is widely used during cardiac surgery, wich is performed using the Minto model. It was derived from patients undergoing general surgery. However, pharmacokinetics of remifentanil can be changed during cardiopulmonary bypass. The investigators tested whether Minto model for target controlled infusion produces constant plasma remifentanil concentration during the cardiac surgery.

NCT ID: NCT02518087 Completed - Acute Kidney Injury Clinical Trials

Increased Adsorption Membranes During Cardiopulmonary Bypass

Start date: September 2016
Phase: N/A
Study type: Interventional

Our project intends to reduce cardiac surgery associated - acute kidney injury (CSA-AKI) in non emergent patients with the use of an increased adsorption membrane (oXiris®) connected to the cardiopulmonary bypass (CPB) circuit, besides evaluating the inflammatory response by quantifying inflammatory mediators during and after cardiac surgery with CPB. Our study is a randomized and controlled multicentre trial that includes recruiting centres with a long experience in cardiac surgery with CPB. The primary endpoint of the project is to evaluate the ability of oXiris® to reduce the incidence of CSA-AKI in patients undergoing non emergent cardiac surgery with an expected CPB time of more than 90 minutes (doble valve replacement or valve replacement plus coronary artery bypass graft). With the goal of reducing by 10% (from 25 to 15%) the risk of CSA-AKI during the first postoperative week a sample size of 340 patients has been calculated. Secondary endpoints are two; first, to evaluate the effect of using oXiris® on survival, clinical course and removal capacity of cytokines and lipopolysaccharide (LPS) during and after CPB; and second, to assess the predictive value for CSA-AKI of some new biomarkers, such as uNAD (urinary nicotinamide adenine dinucleotide).

NCT ID: NCT02471950 Completed - Clinical trials for Cardiopulmonary Bypass

Isoflurane During Cardiopulmonary Bypass

Start date: April 2015
Phase:
Study type: Observational

There is no clinical way of assessing the depth of anaesthesia while patients are on the heart-lung machine. A new method of measuring the depth of anaesthesia using brainwaves called the Bispectral index (BIS) has been developed and its use in cardiac surgery is now widespread. However BIS is also altered by patients body temperature. As cooling is common during heart surgery the use of BIS to measure the depth of anaesthesia during heart-lung bypass remains controversial. This study aims to find out what depth of anaesthesia is produced according to BIS during heart lung bypass using a standard anaesthetic technique that utilises the anaesthetic isoflurane.

NCT ID: NCT02398019 Completed - Clinical trials for Cardiopulmonary Bypass

Clinical Trial to Evaluate the Use of an Adsorption Membrane (oXiris®) During Cardiopulmonary Bypass Surgery

Start date: March 2015
Phase: N/A
Study type: Interventional

Patients whom require cardiopulmonary bypass (CPB) during surgery present systemic inflammatory response syndrome (SIRS) due to blood cell activation and cytokine release to circulation. SIRS can lead to organ dysfunction due to hemodynamic compromise (vasodilatation plus leak syndrome) and/or cytokine mediated cell injury. Renal dysfunction is a major adverse complication after CPB surgery. Investigators hypothesize that the use of an increased adsorption membrane (OXIRIS®) during CPB is safe and presents low technical complexity. The safe use of OXIRIS® will reduce cytokine circulatory levels therefore decreasing SIRS and its systemic effects specially those concerning renal function. Therefore, patients receiving (OXIRIS®) could potentially present less cardiac surgery-associated acute kidney injury (CSA-AKI), and lower intensive care unit (ICU) and hospital length of stay.

NCT ID: NCT02059343 Completed - Pharmacokinetics Clinical Trials

Pharmacokinetics of Dexmedetomidine in Children During Cardiopulmonary Bypass (CPB)

Start date: March 2014
Phase: N/A
Study type: Observational

Dexmedetomidine is increasingly used for sedation in children placed on cardiopulmonary bypass for heart surgery. It is also often used after surgery and may be particularly helpful for children with heart disease. In order for this medication to be helpful and to minimize risks associated with taking the medication, it is important to provide correct dosing for this medication. Based on evidence from studies of other medications used during heart surgery, it is likely that dosing of dexmedetomidine while on cardiopulmonary bypass is different from dosing in other settings. The purpose of this study is to evaluate how the heart-lung bypass machine affects dexmedetomidine levels in the body.

NCT ID: NCT02037555 Completed - Cardiac Surgery Clinical Trials

Safety and Efficacy of Preoperative Antithrombin Supplementation in Patients Undergoing High-Risk Cardiopulmonary Bypass

Start date: June 26, 2014
Phase: Phase 2
Study type: Interventional

This is a prospective, multicenter, randomized, double-blind, placebo-controlled study. The purpose of this study is to determine the safety and effectiveness of human-derived antithrombin III (AT-III [Human]) supplementation prior to high-risk, non-emergency, cardiac surgery with cardiopulmonary bypass (CPB). A total of 404 adult subjects undergoing CPB who meet the study eligibility criteria were planned to be randomized to receive either AT-III (Human) or placebo.
