Trial summary

During general anesthesia, intraoperative hypotension (IOH) is associated with increased morbidity and mortality. Mean arterial pressure (MAP) < 65mmHg is the most common definition of hypotension. Read more about this study

About this study

Official title: Intraoperative Hypotension Predicted by Observation of Mean Arterial Pressure : a Retrospective Cohort Preliminary Study

During general anesthesia, intraoperative hypotension (IOH) is associated with increased morbidity and mortality. Mean arterial pressure (MAP) < 65mmHg is the most common definition of hypotension. In order to reduce IOH, a complex method using machine learning called hypotensive prediction index (HPI) was shown to be superior to changes in MAP (ΔMAP) to predict hypotension (MAP between 65 and 75 excluded). Linear extrapolation of MAP (LepMAP) is also very simple and could be a better approach than ΔMAP. The main objective of the present study was to investigate whether LepMAP could predict IOH during anesthesia 1, 2 or 5 minutes before.

Hypothesis : the area under the ROC curves (ROC Area Under Curves) at 1, 2 and 5 minutes of LepMAP would be superior to ΔMAP

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Data collectedOther

    The variable of the characteristic of the patients (i.e.: age, sex, hypertension, diabetes, atrial fibrillation, coronary arteries diseases, body mass index (BMI), surgery, medications) were retrieved from the anesthesia consultation file (Easily, Hospices Civiles de Lyon, France).

    We retrieved the mean arterial pressure from our local anesthesia software for each patient ( Diane®, Bow medical, Amiens France). We also performed an automatic extraction of data from our anesthesia software (Diane, Bow Medical, France) with a rate of 1 value / minute for some continuous arterial pressure.

    All data was extracted from our institutional database and collected by a physician who was not involved in the care of the study patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. AUC ROC of LepMAP

    The primary outcome measure is the AUC ROC of LepMAP 1, 2 and 5 minute before hypotension to predict hypotension defined as a mean arterial pressure less tha 65 mmHg

    Measured: Only during perioperative period

Questions about this trial

What is this clinical trial studying?

An observational study of Wedge Resection and Lobectomy by Video-thoracoscopies, run by Hospices Civils de Lyon at 1 site in France.

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 3 inclusion and 3 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 7 Dec 2021. 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 France. 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?

AUC ROC of LepMAP (time frame: Only during perioperative period). 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 7 Dec 2021.
