Instrumental Respiratory Physiotherapy in Difficult-to-wean ICU Patients

Официальное название

Randomized Controlled Trial Evaluating the Impact of Intensive, Instrumental and Early Respiratory Physiotherapy on Peak Expiratory Flow in Mechanically Ventilated Patients With ICU-acquired Muscle Weakness

Обзор

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.

Вмешательства

• Процедура Systematic and early intensive instrumental respiratory physiotherapy for patients undergoing difficult ventilatory weaning
  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).
• Процедура Protocolized standard-of-care respiratory physiotherapy
  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
