About this study

The goal of this clinical trial is to learn about Whether carotid ultrasound guided fluid management can reduce the incidence of hypotension after general anesthesia induction in elderly patients undergoing gastrointestinal surgery.

The main question[s] it aims to answer are:

Read more

Whether fluid therapy reduces the incidence of general anaesthesia induced hypotension in elderly patients undergoing gastrointestinal surgery.

Whether carotid ultrasound can guide fluid management in elderly patients undergoing gastrointestinal surgery.

Participants will use carotid ultrasound to assess volume status. If volume is insufficient, fluid therapy will be selected until volume is sufficient, anesthesia will be then induced. If volume is sufficient, anesthesia will be directly induced. There is a comparison group: No carotid ultrasound will be used to assess the volume status of the patients, and anesthesia will be directly induced.

Being tested
Fluid therapy under the guide of Carotid ultrasound

What is being measured

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

  1. Occurrence of hypotension after anesthesia induction

    Hypotension occurred from anesthesia induction to 20 minutes after induction in both groups.

    Measured: General anesthesia induction from the beginning to 20 minutes after induction

Secondary outcomes (3)
  1. Postoperative acute kidney injury

    Postoperative creatinine increased for a short period of time to more than 0.3mg/dl (26.5μmol/L) or to more than 1.5 times the preoperative creatinine concentration.

    Measured: Within 7 days after surgery

  2. postoperative delirium

    Newly diagnosed delirium by the psychiatric department within 30 days after surgery

    Measured: Within 30 days after surgery

  3. postoperative stroke

    Any newly diagnosed postoperative neurological dysfunction within 30 days after surgery.

    Measured: Within 30 days after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Fluid therapy under the guide of Carotid ultrasound in people with Hypotension on Induction, run by Min Su at 1 site in China.

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 5 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: status not confirmed, as of the sponsor's last update on 13 Jun 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 China. 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?

Results are not available in the source record.

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

Contact Jingfeng Bai (15773490489, bjf159323@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of hypotension after anesthesia induction (time frame: General anesthesia induction from the beginning to 20 minutes after induction). 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 13 Jun 2023.
