September 25, 2014 updated by: david orlikowski, Centre d'Investigation Clinique et Technologique 805

Validation of a Dynamic Evaluation Tool in Respiratory Failure by Ambulatory Inductance Plethysmography

Determing optimal time of ventilator disconnection is a challenge for both acute and chronic neuromuscular disease. In one case it is helpful for weanning from ventilator and in the other to optimize daytime ventilation in the most severe patients. The investigators propose to validate a new non invasive tool for monitoring respiratroy parameters in neuromuscular patients in both acute and chronic conditions.

Detailed Description

Context:

Mechanical ventilation transformed the prognosis of neuromuscular diseases whether for acute or chronic diseases. The available tools to estimate the severity of respiratory insufficiency and indicate or follow the efficiency of mechanical ventilation are based on blood gazes explorations, tests respiratory function and sleep evaluation.

These tools give either limited information, or are with difficulty applicable to patients heavily handicapped except during hospitalization.

In patients under mechanical ventilation, it is sometimes difficult to know the daily optimal time of ventilation. The respiratory events are not generally recognized and are unspecific (headaches, drowsiness, dyspnoea, etc.) or are identified by blood gazes abnormalities (hypercapnia. In acute setting, treble is going to raise the problem of the weaning of the mechanical ventilation and the optimal moment of the extubation without risking a reintubation.

These problems are identical and concern the evaluation of the degree of ventilatory autonomy for home care. The development of methods estimating this autonomy is thus fundamental.

Objectives: the objective of this project is to validate a non-invasive system for measure and acquisition of respiratory parameters, incorporating a transmission system working by a "wireless" technology allowing the remote monitoring of these patients.

The secondary objectives are to determine the parameters of success of weaning by using the device in neuromuscular patients intubated for respiratory failure in acute setting and to determine the optimal time of free breathing possibilities in patients ventilated in a chronic way at home.

Methods:

After validation of the device on 10 healthy subjects, continuous acquisition of the ventilatory data by means of the Teleresp system compared with measure of the transcutaneous PCO2, of SaO2 and arterial gazometry at the end of free breath trial in 40 acute and chronic neuromuscular patients.

Selection criteria:

Healthy volunteers Patients affected by acute neuromuscular pathology and starting weaning from invasive ventilation (Guillain Barré and myasthenia).

Patients affected by neuromuscular pathology and home ventilated in a diurnal and night-way by invasive interface or not (respiratory autonomy of at least 1:00 am).

Number of patients, center:

10 healthy volunteers and 40 patients hospitalized in the intensive care unit or in the home of ventilation unit of the Raymond Poincaré hospital.

Total duration of the study: 19 months

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
Number of pathological respiratory events (apneas, hypopneas, paradoxical breath) detected with regard to the recording of the PtCO2 and the SpO2
Time Frame: 1 to 12 hours

Healthy subjects will be recorded for one hour in seated positions 30 minutes and slept 30 min.

Pneumotachograph recording will be realized during 5 minutes at the beginning and at the end of every phase of recording. The computer assuring the reception of the signals being remotely located to estimate of the transmission.

All the patients will be registered in parallel with the VISURESP ® system (RBI Grenoble, France) and the measure of the transcutaneous PCO2 and SpO2(SenTec AG, Therwil, Switzerland) during free breath. The measure beginning 30 minutes before the logout and finishing 30 minutes later.

Acute patients being able to like at least 2 H of free breath will be recorded. A first measure will be made dice that a free breath of at least 2H will be possible, then 3 days later and the day the extubation. Aterial blood gazes will be obtained before reconnection. Chronic patients willbe recorded if able to be disconnected from ventilator for more than 1 hour.
