Brief Summary

Difficult ventilatory weaning is associated with a 20% mortality rate. 40% of these patients will develop intensive care unit (ICU)-acquired neuromyopathy, associated with reduced cough strength and a 4-fold increase in the risk of reintubation. The objective measure of cough strength is peak expiratory flow (PEF). Instrument-assisted coughing is a respiratory physiotherapy technique capable of significantly increasing PEF in chronic neuromuscular patients and draining bronchial secretions. The objective of the study is to determine whether an early, systematic, instrumental, intensive respiratory physiotherapy strategy in patients with difficult ventilatory weaning and ICU-acquired neuromyopathy significantly improves PEF immediately prior to extubation, compared with a conventional, protocolized management strategy.

Outcome Measures

Primary Outcomes (1)

  • Unassisted peak expiratory cough flow (PECF) under mechanical ventilation during a voluntary coughing effort

    PECF measured on the ventilator using its built-in flowmeter (PECF on unassisted coughing under mechanical ventilation). PECF is expressed in L/min.

    At Hour 24

Secondary Outcomes (12)

  • Unassisted PECF after disconnection from mechanical ventilation during a voluntary coughing effort

    At Hour 24, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7

  • Assisted PECF under mechanical ventilation

    At Hour 24, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7

  • Semi-quantitative measurement of cough strength

    At Hour 24, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7

  • Semi-quantitative measurement of cough strength

    At Hour 24, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7

  • Semi-quantitative measurement of bronchial secretion quantity

    At Hour 24, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7

  • +7 more secondary outcomes

Study Arms (2)

Intensive instrumental and early respiratory physiotherapy

EXPERIMENTAL

Patients in this arm will receive instrumental and intensive respiratory physiotherapy strategy from inclusion to day 7, 3 times a day, before and after extubation. Instrumental physiotherapy will be protocolized and cough strength and efficacy of bronchial secretions clearance will be evaluated

Procedure: Systematic and early intensive instrumental respiratory physiotherapy for patients undergoing difficult ventilatory weaning

Protocolized standard-of-care respiratory physiotherapy

ACTIVE COMPARATOR

Patients in this group will receive standardized and protocolized respiratory physiotherapy, i.e. 1 to 2 sessions of manual respiratory physiotherapy (not assisted by an instrumental technique) per day until the day of successful extubation, or until day 7 if necessary.

Procedure: Protocolized standard-of-care respiratory physiotherapy

Interventions

Patients in this group will receive standardized and protocolized respiratory physiotherapy to reproduce the usual practices of non-expert centers,1 to 2 sessions of manual respiratory physiotherapy (not assisted by an instrumental technique) per day until the day of successful extubation, or until day 7 if necessary

Protocolized standard-of-care respiratory physiotherapy

Patients randomized to this group will receive 3 sessions per day of intensive early respiratory physiotherapy with instrumental techniques from randomization to day 7, before and after any extubation. The strategy will be applied until day 7 of randomization, regardless of the patient's status (intubated or not).
