Trial summary

The lower esophageal sphincter(LES)plays a key role in preventing regurgitation and aspiration. The pressure of LES partly comes from striated muscles derived from the crural portion of the diaphragm. The effect of succinylcholine on esophagogastric junction during anesthesia induction is not clear. Read more about this study

About this study

The lower esophageal sphincter(LES)plays a key role in preventing regurgitation and aspiration. The pressure of LES partly comes from striated muscles derived from the crural portion of the diaphragm. The effect of succinylcholine on esophagogastric junction during anesthesia induction is not clear. We conducted a prospective interventional study on the effect of succinylcholine on the barrier pressure (BrP) of the esophagogastric junction.

Read the detailed description

14 patients participated in the study. Propofol and succinylcholine were used for anesthesia induction. High-resolution solid-state manometry (HRM) was used to monitor the changes of the LES pressure and the intragastric pressure (IGP).The administration of propofol could significantly increase the LES pressure during end expiration and during inspiration. The application of succinylcholine had no effect on the LES pressure during end expiration, but significantly reduced the LES pressure during inspiration. Propofol had no effect on BrP. After the application of succinylcholine, BrP decreased significantly during inspiration.

Propofol significantly increased the LES pressure. Succinylcholine significantly reduced the pressure of LES and BrP during inspiration.

What participants receive

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

  • SuccinylcholineDrug

    Also called propofol

    1.5mg/kg was given intravenously

Study groups in NCT05556408
Study groupRoleWhat they receive
High-Resolution Solid-State ManometryOtherBefore catheterization, the patients were monitored by pulse oximetry, electrocardiogram, automatic noninvasive arterial blood pressure and bispectral index (BIS). Before the insertion of the manometric catheter an intravenous cannula was inserted. The manometric catheter was placed through the nose until the pressure from the lower esophageal sphincter to the stomach could be recorded. After confirming the position of the catheter, the catheter was taped to the nose.

What is being measured

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

  1. pressure of lower esophageal sphincter

    On the isocontour plots, the esophageal sphincter can be located as abrupt transitions in the pressure pattern (Fig. 2). The proximal edge of the LES was defined by sudden transition to the intra-esophageal pressure, and the distal edge was defined by sudden transition to the IGP. The pressure of the LES measured during end expiration was defined as the pressure of intrinsic sphincter to avoid the influence from the rural component of the LES. The rural component of the LES was defined as the highest pressure point at the esophagogastric junction during inspiration.

    Measured: 15 minutes

  2. pressure of intragastric

    IGP was measured at 2 cm below the crural diaphragmatic component of the LES

    Measured: 15 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Succinylcholine in people with the Effect of Succinylcholine on Barrier Pressure, run by China-Japan Friendship Hospital.

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

Who may be eligible to take part?

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 27 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

pressure of lower esophageal sphincter (time frame: 15 minutes). The study lists 2 primary outcomes in all. 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 27 Sep 2022.
