A Comparison of Different Ventilation Strategies in Infants Using the PLMA™

March 9, 2022 updated by: Wake Forest University

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 month to 11 months (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. ASA (American Society of Anesthesiologists) physical classification of 1 or 2
  2. Outpatient surgical procedures
  3. Surgical procedure anticipated to be < 90 minutes
  4. Subject age of 1 - 11 months (inclusive)

Exclusion Criteria:

  1. Inpatient- Such individuals may have underlying disease processes which puts them at an increased risk under general anesthesia for hypoventilation
  2. ASA physical classification of 3, 4 or E
  3. Premature infants or infants < 44 weeks post-conceptual age
  4. Risk of aspiration- Intubation with an endotracheal tube may be required for general anesthesia.
  5. Patients with malignant hyperthermia or family history of malignant hyperthermia- Administration of inhalational agents for general anesthesia is contraindicated.
  6. Patients with tracheostomies- The individual's airway is already established and PLMA™ placement is not required.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Spontaneous ventilation
Other: Spontaneous ventilation
The patient will breathe spontaneously (on their own) while under general anesthesia throughout the duration of the surgery.
Experimental: Pressure support ventilation
Device: Pressure support ventilation
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.
Active Comparator: Pressure control ventilation
Device: Pressure control ventilation
The patient's ventilation will be completely supported by the anesthesia machine while under general anesthesia throughout the duration of the surgery.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
