About this study

Official title: Optimal Inspiratory Pressure for Facemask Pressure-controlled Ventilation in Children: Study Using Detection of Gastric Insufflation Using Ultrasonography of the Antrum and Epigastric Auscultation

The purpose of this study is to find an optimal inspiratory pressure to provide adequate tidal volume and prevent gastric insufflation in pediatric patients.

The children under 5 years old are randomly assigned to muscle relaxation group and non-relaxation group. For muscle relaxation group, routine anesthesia induction is performed with muscle relaxant and mask ventilation is started by pressure-controlled mechanical ventilation. Gastric auscultation and abdominal ultrasonography are performed simultaneously during mask ventilation to detect inflow of air. Initial inspiratory airway pressure is 10 cmH2O and increased gradually by 2 cmH2O until gastric insufflation is detected by either of two methods. Tracheal intubation is done after detection of gas.

For non-relaxation group, mask ventilation is performed in a same manner, without muscle relaxant. After detection of gas by any of the two methods, rocuronium 0.6 mg/kg is administered and tracheal intubation is performed.

Read the detailed description

The purpose of this study is to find an optimal inspiratory pressure to provide adequate tidal volume and prevent gastric insufflation in pediatric patients.

The children under 5 years old are randomly assigned to muscle relaxation group and non-relaxation group. Stratum was constructed based on age and randomization scheme was performed separately within each stratum. Block randomization was done to ensure balance of the age groups.

For muscle relaxation group, routine anesthesia induction is performed with muscle relaxant and mask ventilation is started by pressure-controlled mechanical ventilation. Gastric auscultation and abdominal ultrasonography are performed simultaneously during mask ventilation to detect inflow of air. Initial inspiratory airway pressure is 10 cmH2O and increased gradually by 2 cmH2O until gastric insufflation is detected by either of two methods. Tracheal intubation is done after detection of gas.

For non-relaxation group, mask ventilation is performed in a same manner, without muscle relaxant. After detection of gas by any of the two methods, rocuronium 0.6 mg/kg is administered and tracheal intubation is performed.

Tidal volume and oxygen saturation are recorded during study period.

What participants receive

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

  • Mask ventilationOther

    Mask ventilation is performed after administration of rocuronium or not. Initial inspiratory pressure is set as 10 cmH2O and increased gradually by 2 cmH2O until gastric insufflation is detected by either of two methods. Tracheal intubation is done after detection of gas.

  • RocuroniumDrug

    Rocuronium 0.6 mg/kg is injected before mask ventilation in muscle relaxant group or after finish of study in non-relaxant group.

What is being measured

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

  1. Inspiratory Pressure That Cause Gastric Insufflation

    Difference in the inspiratory pressure that minimized the incidence of gastric insufflation, yet guaranteed a tidal volume of at least 6 ml/kg between the neuromuscular blocker and non-neuromuscular blocker groups.

    Gastric insufflation was measured using both gastric ultrasonography and epigastric auscultation.

    Measured: Interval between start of mask ventilation and detection of gastric insufflation, an expected average of 100 sec

  1. Diagnostic Method That Detects Gastric Insufflation First

Questions about this trial

What is this clinical trial studying?

A study testing Mask ventilation and Rocuronium in people with Child and Anesthesia, run by Seoul National University Hospital at 1 site in South Korea.

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 6 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 31 Jan 2019. 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 South Korea. 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?

Yes. Results are posted in the registry (first posted 31 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Inspiratory Pressure That Cause Gastric Insufflation (time frame: Interval between start of mask ventilation and detection of gastric insufflation, an expected average of 100 sec). 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 NCT02471521, which also lists 1 linked publication.

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 31 Jan 2019.
