Lung Ultrasonography After Major Cardiac Surgery (ECHOVAP)

September 11, 2023 updated by: Adrien Bouglé, Groupe Hospitalier Pitie-Salpetriere

Usefulness of Lung Ultrasonography for Diagnosis of Pneumonia After Major Cardiac Surgery: a Pilot Study

Diagnosis of pneumonia remains difficult in intensive care unit (ICU), notably after cardiac surgery. Lung ultrasonography (LUS) has been successfully used for diagnosis of pneumonia, but its usefulness and reliability was never evaluated after cardiac surgery. This study investigates the clinical relevance of LUS for pneumonia diagnoses in cardiac ICU.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with acute respiratory failure after cardiac surgery and hospitalized in the surgical Intensive Care Unit of ICU of Cardiology Institute, Pitié Salpêtrière University Hospital, Paris, France

Description

Inclusion Criteria:

  • Cardiac surgery with sternotomy and cardio-pulmonary bypass (CPB) less than 3 days before

  • At least one component suggestive of ARF:

    • If mechanical ventilation, a PaO2 / FiO2 ratio <200, or failure of weaning (failure of spontaneous ventilation test, re-intubation in the first 24 hours), or need for non-invasive ventilation immediately after extubation,
    • If spontaneous ventilation: clinical signs of acute respiratory distress (dyspnea at least exertion, cyanosis, polypnea> 25/min, upper or intercostal swallowing, abdominal swing ...), SpO2 < 90% or PaO2 <60 mmHg despite oxygen therapy ≥ 3L/min.

Exclusion Criteria:

  • Minor patients
  • Pregnancy
  • Sleep apnea syndrome
  • Participation refusal

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Post operative respiratory failure

Patients with acute respiratory failure (ARF) less than 72 hours after a major cardiac surgery with cardiopulmonary bypass

ARF was defined as one of the following conditions:

  • If mechanical ventilation, a partial pressure of oxygen/ inspired oxygen fraction ratio (PaO2/FiO2) < 200, or failure of weaning (failure of spontaneous ventilation test, re-intubation in the first 24 hours), or need for non-invasive ventilation immediately after extubation,
  • If spontaneous ventilation: clinical signs of acute respiratory distress (dyspnea at least exertion, cyanosis, polypnea> 25/min, upper or intercostal swallowing, abdominal swing ...), pulse oximetry (SpO2) < 90% or PaO2 <60 mmHg despite oxygen therapy ≥ 3 L/min.
Diagnostic test: Lung Ultrasound

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
Final diagnosis of pneumonia
Time Frame: During the 72 hours following surgery

Pneumonia or excluded pneumonia, was determined by consensus of 3 investigators, after an independent post hoc review of the medical records. Pneumonia diagnosis was based on concordance of clinical and radiological criteria (≥ 2 criteria including fever> 38.5 ° C or T <36 ° C, leukocytosis> 10 ^ 9 / L or leukopenia <4.10 ^ 8 / L, purulent tracheal secretions and the appearance or persistence of an infiltrate on the CXR).

It should be confirmed by culture of a respiratory specimen: protected distal sampling with a threshold of significance ≥ 10 ^ 3 colony forming unit/mL or bronchoalveolar lavage with a threshold of significance ≥ 10 ^ 4 CFU/mL.

Study Major Dates

Study Start (Actual)

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.
January 1, 2015

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
