Fluid Leakage Past Tracheal Tube Cuff : Effect of Suctioning Manoeuvre

March 4, 2011 updated by: Centre Hospitalier de Roanne
The leakage of oropharyngeal secretions around high-volume low-pressure tracheal tube cuffs is usually considered as a major risk factor for bacterial tracheal colonization and subsequent development of ventilator-associated pneumonia. The rate of leakage around the cuff is related to the pressure differential across the cuff, namely the difference between the pressure of the subglottic fluid above the cuff and the tracheal pressure under the cuff. Consequently, positive end-expiratory pressure (PEEP) improves the sealing around the cuff towards fluid leakage. However, this preventive effect of PEEP is compromised during prolonged mechanical ventilation by tracheal suctioning manoeuvre, which may enhance fluid leakage, by decreasing tracheal pressure. Indeed, in a benchtop model, a suctioning manoeuvre, without disconnection of the ventilator, induced a constant fluid leakage past a high-volume low-pressure tracheal tube cuff when performed with a high level of suction pressure (- 400 mbar) and a large size of suction catheter size (16 French).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

This clinical study aims to confirm these experimental data in patients under mechanical ventilation.

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

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.
Outcome Measure
Measure Description
Time Frame
Presence of blue dye in the trachea and/or the bronchi after the suctioning manoeuvre.
Time Frame: 48 hours after the beginning of the mechanical ventilation
The cuff pressure will be first checked and reset at 30 cm H2O if needed. Next, blue dye will be instilled just above the cuff through the lumen ending in the subglottic area of the Hi-Lo Evac tube. Then a suctioning manoeuvre will be performed with a suction pressure of - 400 mbar through a 16 French suction catheter. Thereafter, a fiberoptic bronchoscopy will be performed, looking for the presence of blue dye in the trachea and/or the bronchi.
48 hours after the beginning of the mechanical ventilation

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
