Efficiency and Safety of the Prolonged Use of Heat and Moisture Exchangers in ICU
Sponsor: Charles University, Czech Republic
Summary
FILTRex is a single-centre, controlled, randomised, prospective, non-inferiority clinical trial to compare the efficiency and safety of prolonged (72-hours) versus standard (24-hours) duration of use for Heat and Moisture Exchange (HME) filters in adult mechanically ventilated critically ill patients
Official title: Safety and Efficiency of the Prolonged (72-hour) Use of a Single Heat and Moisture Exchanger in Adult Mechanically Ventilated Critically Ill and Its Impact on the Lower Respiratory Tract Pathogenic Microbial Colonisation Rate (FILTRex Trial); a Single-centre, Randomised, Controlled Trial

72-hour HME exchange interval group
All patients in the experimental arm will receive the usual best medical and nursing care with respect to VAP prevention. A dual-limb ventilator circuit with a closed suction system will be used. Bronchodilation or inhalational antibiotics, when ordered, will be delivered by a meshed nebuliser, a part of the ventilatory support circuit and will not be removed between treatments. A closed-circuit suction device will be used, and the frequency of suctioning will be monitored, including the sputum consistency and blood on suctioning. HME filter resistance by estimating the pressure drop over HME using the ventilatory circuit's auxiliary force (Paux) and flow. Temperature and humidity in the ventilator circuit will be measured. HME filters will be exchanged every 72 hours. At the exchange point, both outlets of the HME filter will be swabbed.
24-hour HME exchange interval group
All patients in the control arm will receive the usual best medical and nursing care with respect to VAP prevention. A dual-limb ventilator circuit with a closed suction system will be used. Bronchodilation or inhalational antibiotics, when ordered, will be delivered by a meshed nebuliser, a part of the ventilatory support circuit and will not be removed between treatments. A closed-circuit suction device will be used, and the frequency of suctioning will be monitored, including the sputum consistency and blood on suctioning. HME filter resistance by estimating the pressure drop over HME using the ventilatory circuit's auxiliary force (Paux) and flow. Temperature and humidity in the ventilator circuit will be measured. HME filters will be exchanged every 24 hours. At the exchange point, both outlets of the HME filter will be swabbed.
