About this study

Official title: A Comparison of Different Ventilation Strategies in Infants Using the Proseal™ Laryngeal Mask Airway

The purpose of this research study is to compare difference between breathing by oneself or with the partial help from an anesthesia machine in infants under general anesthesia.

Hypothesis: Infants undergoing general anesthesia with a PLMA™ will be better ventilated (improved breathing) with the help of the breathing machine versus breathing on their own.

Read the detailed description

The laryngeal mask airway (LMA) is a breathing device that sits above the vocal cords and allows the patient to breathe in and out adequately under general anesthesia (GA). The ProSeal™ laryngeal mask airway (PLMA™) is a specialized type of LMA with a design that permits the delivery of higher pressures to help the patient breathe in and out (ventilate) and also contains a channel to suction the stomach.

Infants under GA may breathe through a PLMA in different ways. Spontaneous ventilation consists of the infants breathing on their own through a PLMA™. Pressure support ventilation allows the patient to breathe on their own with additional help from the anesthesia machine. Pressure control ventilation allows the patient to breathe with the help of an anesthesia machine.

An infant undergoing surgery requires a deep level of general anesthesia which negatively affects their ability to ventilate. Thus, infants may not breathe in oxygen and carbon dioxide out adequately at this level of anesthesia and it may be beneficial to provide some level of support to enhance carbon dioxide exchange and to avoid hypoventilation.

This study will attempt to determine whether pressure support ventilation improves ventilation in infants undergoing outpatient surgery.

What participants receive

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

Spontaneous ventilationOther
The patient will breathe spontaneously (on their own) while under general anesthesia throughout the duration of the surgery.
Pressure support ventilationDevice
The patient will breathe on their own and with a little assistance from the anesthesia machine while under general anesthesia throughout the duration of the surgery.
Pressure control ventilationDevice
The patient's ventilation will be completely supported by the anesthesia machine while under general anesthesia throughout the duration of the surgery.

Where is the study taking place?

The record lists 1 site in United States. 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 16 Jan 2018). 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?

Mean Values of End-tidal Carbon Dioxide and Tidal Volume Compared Between the Spontaneous Ventilation and Pressure Support Ventilation Groups. (time frame: Up to 45 minutes). The study lists 3 primary outcomes in all. 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 NCT03235817, 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 18 Mar 2022; AzTrials last refreshed its copy on 6 Nov 2026.
