Biomarkers and Bowel Sounds in Patients With Acute Gastrointestinal Injury (BABSIPWAGI)

July 29, 2022 updated by: First Affiliated Hospital Xi'an Jiaotong University

Study on the Value of Digital Continuous Bowel Sound Monitoring in AGI of Critically Ill Patients With ICU

The incidence of gastrointestinal diseases is high in intensive care unit (intensive care unit,ICU). In critically ill patients, the intestinal tract is the "engine" of multiple organ dysfunction syndrome (Multiple organ dysfunction syndrome,MODS) and a component of multiple organ dysfunction syndrome, which is closely related to the poor prognosis of critically ill patients. In 2012, the abdominal working group of the European Association of critical Care Medicine (the European Society of Intensive Care Medicine,ESICM) put forward the concept of "acute gastrointestinal injury" (acute gastrointestinal injury,AGI), which was defined as gastrointestinal dysfunction caused by acute disease in critically ill patients. However, the grading system is complex and general, which does not reflect other gastrointestinal functions such as endocrine, immunity, barrier and so on, and lacks the support of objective laboratory results. When patients with acute gastrointestinal injury, gastrointestinal digestion and absorption, endocrine, immunity, barrier function are affected in varying degrees. The levels of indexes reflecting gastrointestinal digestion and absorption, endocrine and immunity were different among different AGI grades. The purpose of this study was to observe the characteristics of AGI bowel sounds in critically ill patients with ICU by digital continuous bowel sound monitoring, and to explore the clinical value of bowel sounds characteristics in AGI of critically ill patients combined with the changes of biomarkers of gastrointestinal injury.

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

In this study, digital bowel sound monitoring equipment was used to continuously monitor the bowel sound of critically ill patients with ICU. This technology added the intestinal sound characteristic database to the data processing center, analyzed and identified the intestinal sound data through the intestinal sound recognition algorithm, further analyzed the parameters such as audio frequency, spectrum and power spectrum, and observed the changes of biomarkers such as citrulline and intestinal fatty acid binding protein.

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

18 years to 80 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

The critically ill patients treated in the Department of intensive Care of the first affiliated Hospital of Xi'an Jiaotong University were selected as the sample source.

Inclusion Criteria:

  • Patients ≥ 18 years old and ≤ 80 years old.
  • The time of staying in ICU is expected to be more than 48 hours.

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.

AGI group
Collect the characteristic data of intestinal sound, such as 24-hour average intestinal rate, duration of gastrointestinal sound, amplitude, maximum frequency, average frequency, etc., and detect citrulline, intestinal fatty acid binding protein and so on.
Other: Bowel sound
The characteristic data of bowel sounds, such as 24-hour average intestinal rate, duration of gastrointestinal sounds, amplitude, maximum frequency and average frequency, were collected to observe the differences of intestinal sounds among different AGI grades.
non-AGI group
Collect the characteristic data of intestinal sound, such as 24-hour average intestinal rate, duration of gastrointestinal sound, amplitude, maximum frequency, average frequency, etc., and detect citrulline, intestinal fatty acid binding protein and so on.
Other: Bowel sound
The characteristic data of bowel sounds, such as 24-hour average intestinal rate, duration of gastrointestinal sounds, amplitude, maximum frequency and average frequency, were collected to observe the differences of intestinal sounds among different AGI grades.
