About this study

Official title: The Effect of End-expiratory Positive Pressure on Gastric Residual Volume in Elective Pediatric Outpatient Surgery Where Laryngeal Mask is Applied

This study was designed as a prospective observational study.

Read the detailed description

In this study, it was planned to evaluate the effect of positive end-expiratory pressure on gastric residual volume in patients who will undergo outpatient pediatric surgery with laryngeal mask application on the specified dates. Patients aged 1-11 years, ASA I-II and undergoing outpatient lower abdominal and genitourinary surgery were included in the study. Since the use of positive end-expiratory pressure varies in our clinic depending on the anesthesiologist preference, the effect of this application on gastric volume will also be evaluated primarily by recording images with gastric ultrasonography at certain perioperative time periods. Secondarily, the effect of this positive end-expiratory pressure on mechanical ventilator parameters and airway pressures will be evaluated.

What is being measured

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

  1. Gastric residual volume

    The primary purpose of this study is to measure gastric residual volume with peroperative gastric ultrasonography measurements. Gastric residual volume will be calculated according to gastric ultrasonography measurements.

    Measured: preoperatively, intraoperatively after laryngeal mask placement, before laryngeal mask removal at the end of surgery

Secondary outcomes (1)
  1. Airway pressures

    The secondary aim of this study was to evaluate the effect of positive end-expiratory pressures on airway pressures

    Measured: intraoperative process

Questions about this trial

What is this clinical trial studying?

An observational study of Pediatrics and Fasting Period, run by Duygu Akyol at 1 site in Turkey (Türkiye).

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 4 inclusion and 5 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 19 Sep 2025. 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 Turkey (Türkiye). 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?

Gastric residual volume (time frame: preoperatively, intraoperatively after laryngeal mask placement, before laryngeal mask removal at the end of surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06426394, which also lists 4 linked publications.

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 19 Sep 2025.
