About this study
Official title: Pre-operative Ultrasonographic Evaluation of Caval Aorta Diameter Index as a New Predictor for Hypotension After Induction of General Anaesthesia: A Prospective Observational Cohort Study.
Comparison between ultrasound measurement of IVCD-AOd index in prediction of post induction hypo tension
Read the detailed description
This study aims to evaluate the ability of preoperative ultrasound measurements IVC to aorta diameter index to predict post-induction hypotension in comparison with ultrasound measurements of the IVC collapsibility index.
- Conditions
- Hypotension on Induction
What is being measured
The primary outcome is the main question the study is designed to answer.
• Comparison of the accuracy Area under receiver operating characteristic curves (AUROC) of IVCD:AoD index and IVCCI in prediction of post-induction hypotension
Measurement of pre-operative IVC-AOrta diameter index and IVC collapsibility index
Measured: 15 minutes

Questions about this trial
What is this clinical trial studying?
An observational study of Hypotension on Induction, run by Cairo 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 9 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 5 Jul 2023. 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?
• Comparison of the accuracy Area under receiver operating characteristic curves (AUROC) of IVCD:AoD index and IVCCI in prediction of post-induction hypotension (time frame: 15 minutes). 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 5 Jul 2023; AzTrials last refreshed its copy on 7 Nov 2026.
