Trial summary

The study assumed that supraglottic jet ventilation is an alternative solution as a safe way to do the preoxygenation before endotracheal intubation by contrasting it with mask pressurized ventilation. The investigators also expected that supraglottic jet ventilation won't increase the occurrence of esophageal reflux. Read more about this study

About this study

Official title: Feasibility of Preoxygenation by Supraglottic Jet Ventilation Substituted for Mask Pressurized Ventilation Before Endotracheal Intubation:A Randomized Controlled Trail

The study assumed that supraglottic jet ventilation is an alternative solution as a safe way to do the preoxygenation before endotracheal intubation by contrasting it with mask pressurized ventilation. The investigators also expected that supraglottic jet ventilation won't increase the occurrence of esophageal reflux.

Read the detailed description

The study assumed that supraglottic jet ventilation is an alternative solution as a safe way to do the preoxygenation before endotracheal intubation by contrasting it with mask pressurized ventilation. The investigators also expected that supraglottic jet ventilation won't increase the occurrence of esophageal reflux.

The investigators randomly divided the patients into 2 groups:Group C and Group S.Patients in Group C will be preoxygenation with mask pressurized ventilation while patients in Group S with supraglottic jet ventilation by Wei NASAL JET(WNJ).The tracheal intubation will be done after the 3 minutes preoxygenation. The investigators will measure the PaCO2 before and after preoxygenation, and the investigators will take the stomach-ultrasonography to find if there are too much gas in the gastro. If pulse oximetry is lower than 95% during the preoxygenation, the investigators will adjust the position of the Wei NASAL JET(WNJ) or use the change the way that the investigators hold the mask or change the pressure of ventilation on the basis of the group.

What participants receive

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

  • supraglottic jet ventilationDevice

    patients who were randomized into supraglottic jet ventilation group would be placed Wei Nasal Jet Tube after conducted. Then they will get the supraglottic jet ventilation to make sure their pulse oximetry is over 95%. After 3 minutes, endotracheal intubation was performed via mouth approach.

supraglottic jet ventilation groupExperimentalCheck blood gas before induction without preoxygen. Take stomach-ultrasound. Induction with Midazolam 0.02 mg/kg, sufentanil 0.3 ~ 0.5 ug/kg, propofol 2-2.5 mg/kg, rocuronium 0.6 mg/kg.After patients fall asleep and can't be woke up ,the investigators will put the Wei NASAL JET(WNJ)into one's nose to give the supraglottic jet ventilation with the driving pressure 0.01-0.03 megapascal (MPa), respiratory rate 15 beats per minute(BPM), inspiratory/expiratory rate 1-1. 5.Check blood gas,stomach-ultrasound after 3 min, then do the tracheal intubation guided by visual laryngoscope.Stop jet ventilation during intubation.

Induction with Midazolam 0.02 mg/kg, sufentanil 0.3 ~ 0.5 ug/kg, propofol 2-2.5 mg/kg, rocuronium 0.6 mg/kg.After patients fall asleep and can't be woke up ,the investigators will give them 1 min mask pressure respiration, by pressure control "V - E technique" after muscle relaxant. Check blood gas,stomach-ultrasound after 2 min, then do the tracheal intubation guided by visual laryngoscope.

What is being measured

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

  1. alveolar oxygen tension(PaO2)

    The results comes from blood gas analysis

    Measured: 3 minutes after preoxygenation

  2. alveolar oxygen tension(PaO2)

    The results comes from blood gas analysis

    Measured: baseline (before preoxygenation)

Secondary outcomes (5)
  1. PaCO2

    The results comes from blood gas analysis

    Measured: 3 minutes after preoxygenation

  2. PaCO2

    The results comes from blood gas analysis

    Measured: baseline (before preoxygenation)

  3. gastric antrum cross section

    The results comes from the ultrasound of gastric

    Measured: 3 minutes after preoxygenation

  4. gastric antrum cross section

    The results comes from the ultrasound of gastric

    Measured: baseline (before preoxygenation)

  5. complications

    such as nasal bleeding, dry throat itching, sore throat, nausea and vomiting, pressure and other adverse reactions

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing supraglottic jet ventilation in people with Preoxygenation, run by Peking University People's Hospital 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 4 inclusion and 4 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 21 May 2020. 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 Hansheng Liang, MD (13717929362, doctorlianghsh@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

alveolar oxygen tension(PaO2) (time frame: 3 minutes after preoxygenation). 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 21 May 2020.
