About this study

Official title: Internal Jugular Vein Sonogram Versus Electrical Cardiometry For Assessment Of Fluid Responsiveness In Adult Undergoing Coronary Artery Bypass Graft Surgery

The primary aim of the study is to assess the reliability of predicting fluid responsiveness in adults undergoing coronary artery bypass graft surgery using sonogram of the internal jugular vein for assessment of vessel distensibility in relation to stroke volume variation (SVV) measaured by electrical cardiometry.

The secondary aim is to evaluate the ability of thoracic fluid content (TFC) measured by electrical cardiometry to be an additive value for the assessment of fluid responsiveness.

Read the detailed description

Fluid management is one of the most important treatments for stabilizing hemodynamics in patients after cardiac surgery.Electrical Cardiometry is a method for the non-invasive determination of stroke volume (SV), cardiac output (CO), stroke volume variation (SVV) and other hemodynamic parameters in adults, children, and neonates based on measurement of thoracic electrical bioimpedance and has been validated against "gold standard" methods such as thermodilution method of deriving CO using a pulmonary artery catheter (PAC).

The IJV is, technically, much more easily accessible for sonographic visualization than the IVC, and measurement of the IJV does not require transesophageal echocardiography (TEE). Internal jugular vein distensibility index (IJVDI) has been studied in several studies but its reliability has not been well confirmed in patients during cardiac surgery.

This is a prospective observational study of adults undergoing coronary artery bypass graft surgery . The primary aim of the study is to assess the reliability of predicting fluid responsiveness in adults undergoing coronary artery bypass graft surgery using sonogram of the internal jugular vein for assessment of vessel distensibility in relation to stroke volume variation (SVV) measaured by electrical cardiometry.The secondary aim is to evaluate the ability of thoracic fluid content (TFC) measured by electrical cardiometry to be an additive value for the assessment of fluid responsiveness.

Volume responsiveness will be independently assessed by IJV sonogram and electrical cardiometry in following times

  1. After induction of anesthesia.
  2. After transfusing 6 ml / kg of hydroxyethyl starch (HES) 6% before sternotomy.
  3. After closure of the sternum and transfusion of patient's blood.
  4. Immediately before transferring the patient to ICU and stabilization of hemodynamic parameters by giving fluids needed to patient.
  5. Immediately after transferring the patient to ICU and stabilization of hemodynamic parameters by giving fluids needed to patient.
  6. After 2 hour of ICU admission.
  7. Before weaning from mechanical ventilation Fluid responsiveness will be assessed by examining SVV with a threshold of the SVV = 12% allow discrimination between Responders and Non-responders

Questions about this trial

What is this clinical trial studying?

An observational study of Ultrasound of IJV and Electrical Cardiometry, run by Ahmed Abd El-Rahim Abd El-Hamid Hammad at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

fluid responsiveness after fluid challenge (time frame: 24 hours from the start of surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04618419, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2020.
