Internal Jugular Vein Collapsibility Index as a Predictor of Hypotension
An observational study of Intraoperative Hypotension, run by Ain Shams University at 1 site in Egypt.
Trial summary
The internal jugular vein (IJV) collapsibility index has been proposed as a practical alternative of of the inferior vena cava collapsibility index (IVC-CI), as it is easily accessible using bedside ultrasonography. Read more about this study

About this study
Official title: Internal Jugular Vein Collapsibility Index as a Predictor of Hypotension After The Induction of General Anesthesia in Geriatric Patients Undergoing Laparoscopic Colorectal Surgeries: A Prospective Observational Study
The internal jugular vein (IJV) collapsibility index has been proposed as a practical alternative of of the inferior vena cava collapsibility index (IVC-CI), as it is easily accessible using bedside ultrasonography. Several studies have demonstrated a correlation between IJV collapsibility and central venous pressure as well as right atrial pressure.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Several studies have demonstrated a correlation between IJV collapsibility and central venous pressure as well as right atrial pressure.

Questions about this trial
What is this clinical trial studying?
An observational study of Intraoperative Hypotension, run by Ain Shams University 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 2 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 20 Jul 2026. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ibrahim Mamdouh Esmat (01001241928, ibrahim_mamdouh@med.asu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Optimal cut-off value of ultrasound guided Internal Jugular Vein Collapsibility Index (percent) (%) to predict post induction hypotension. (time frame: The first 15 minutes after induction of general anesthesia.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 20 Jul 2026.
