Capnographic Monitoring in Gastrointestinal Endoscopy for Elderly Patients (CapnoGI)

March 17, 2024 updated by: diansan su, RenJi Hospital

Capnographic Monitoring Decrease the Incidence of Hypoxia of the Elderly Patients Undergoing Gastrointestinal Endoscopy Procedure: a Randomized Multicenter Clinical Trial

Hypoxia is the most common adverse event in gastrointestinal endoscopes sedated with propofol and sufentanil, especially in elderly people. The aim of this randomized study was to determine whether intervention based on additional capnographic monitoring reduces the incidence of hypoxia in gastrointestinal endoscopes procedures for elderly patients.

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.

Arms and Interventions

Participant Group / Arm

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: Capnographic monitoring group
In this group, in addition to the standard monitoring including observation, pulse oxygen saturation, non-invasive blood pressure, electrocardiogram in selected patients, the capnographic is also monitored. The capnographic data of the patients are available for additional noninvasive assessment of ventilation.
Device: Capnography monitoring
Standard monitoring and capnographic monitoring.
Device: Standard monitoring
Standard monitoring but no capnographic monitoring
Active Comparator: Standard monitoring group
In this group, standard monitoring including observation, pulse oxygen saturation, non-invasive blood pressure, electrocardiogram in selected patients. Capnographic data are not visible by closing the CO2 sampling line till the endoscopy end.
Device: Standard monitoring
Standard monitoring but no capnographic monitoring

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
The incidence of hypoxia
Time Frame: Patients will be followed for the duration of hospital stay, an expected average of 2 hours
(75% ≤ SpO2 < 90% for <60 s)
Patients will be followed for the duration of hospital stay, an expected average of 2 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The incidence of severe hypoxia
Time Frame: Patients will be followed for the duration of hospital stay, an expected average about 2 hours
(SpO2 < 75% or 75% ≤ SpO2 < 90% for >/=60 s)
Patients will be followed for the duration of hospital stay, an expected average about 2 hours
The incidence of sub-clinical respiratory depression
Time Frame: Patients will be followed for the duration of hospital stay, an expected average about 2 hours
(90% ≤ SpO2 < 95%)
Patients will be followed for the duration of hospital stay, an expected average about 2 hours
The incidence of capnography curve decreased by half or more than the baseline and even disappeared without hypoxia
Time Frame: Patients will be followed for the duration of hospital stay, an expected average about 2 hours
capnography curve decreased by half or more than the baseline and even disappeared, SpO2 >90%
Patients will be followed for the duration of hospital stay, an expected average about 2 hours
The incidence of other adverse events
Time Frame: Patients will be followed for the duration of hospital stay, an expected average about 2 hours
Other adverse events recorded by tools proposed by the World Society of Intravenous Anesthesia International Sedation Task Force
Patients will be followed for the duration of hospital stay, an expected average about 2 hours
