UltraSound for Accurate Decisions in Chest PhysioTherapy

Summary

Introduction: Physiotherapist usually uses a clinical examination, including auscultation, an analysis of blood gasses and chest imaging to determine the indication for chest physiotherapy, to choose the treatment protocol and evaluate the efficacy of the management. Lung ultrasound (LUS) presents greater accuracy than chest X-ray in the diagnosis of lung deficiencies interesting the physiotherapist. So, it could allow the physiotherapist to determine the indication for chest physiotherapy and thus avoid unnecessary or inappropriate treatments. No study has evaluated the impact of LUS on clinical decisions in chest physiotherapy in ICU patients.

Objective: To evaluate the impact of using the results of lung and diaphragm US on clinical decisions in chest physiotherapy in hypoxemic patients hospitalized in ICU.

Method: The physiotherapist carries out a clinical examination and analyses the complementary tests (chest X-ray, chest CT-scan and blood gasses if available). Following the examination, he will put forward one or several hypotheses concerning the respiratory deficiency and will confirm or not the indication for chest physiotherapy. If respiratory physiotherapy is indicated, the physiotherapist will specify the protocol.

A lung and diaphragm US will be done following the evaluation of the clinical physiotherapist, and will make it possible to answer the question: are the results of the lung and diaphragm US compatible with the hypotheses put forward? The LUS report will be given to the clinical physiotherapist. He will specify the respiratory physiotherapy protocol according to the results of the US-scan.

The modification of the clinical decision will be assessed with the Net Reclassification Index (NRI).

Expected results: We expect that decisions for chest physiotherapy will be modified by LUS. The expected benefit for patients is therefore that they will be given a chest physiotherapy protocol that is better suited to the type of respiratory deficiency they are suffering from.

Conditions

• Critical Illness
• Respiratory Disease

Interventions

DIAGNOSTIC_TEST

Lung and diaphragm ultrasound

The ultrasound physiotherapist/operator performs a lung and diaphragm ultrasound. He is blinded to the patient's status and clinical physiotherapist examination. He/she is not involved in patient management or patient clinical decision-making. The ultrasound findings are recorded in the LUS report. The LUS report is reported to the clinical physiotherapist and to the intensivist. The ultrasound diagnosis(es) is recorded.

DIAGNOSTIC_TEST

Lung and diaphragm ultrasound in MV patients

In case of mechanically ventilated patient at St. Vincent Hospital (Sydney, Australia), LUS scan will be performed immediately following intubation. Additionnal LUS scans will be performed 72h after intubation and Immediately prior to or following extubation.
