About this trial

This is an interventional treatment trial for Respiratory Failure focused on measuring Proportional assist ventilation, Pressure support ventilation, Weaning, Prolonged mechanical ventilation

Eligibility Criteria

20 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients with prolonged mechanical ventilation and transfer to respiratory care center, age of 20 years or older, at least 1 time of extubation failure or spontaneous breathing trial failure in ICU, stable hemodynamics, no vasopressor use, FiO2 = 0.40 or less, external positive end-expiratory pressure = 5 cmH2O or less, PaO2 > 60 mmHg, and body temperature < 38ºC (within 24 hours).

Exclusion Criteria:

  • Patients with bronchopleural fistulas, central neurological disorders, hemodialysis, and those with pressure support level already < 15 cmH2O.

Outcomes

Primary Outcome Measures

28-day weaning success rate
Weaning success was defined as being alive and liberation from MV for more than 48 hours.

Secondary Outcome Measures

Weaning duration
Weaning duration was defined as the time from randomization to successful liberation from MV. For those who failed to liberate from MV throughout the course of weaning trial, the weaning duration was defined from randomization to the end of study (up to 28 days).
Hospital length of stay
Patients were followed to discharge to calculate the length of hospitalization
Weaning success at discharge
Patients were followed to discharge to calculate weaning success rate at discharge, which is defined as status of being alive and successful weaned at patient discharge
Hospital mortality
Patients were followed to discharge to calculate the mortality rate during hospitalization.

5. Study Description

Brief Summary
A prospective randomized controlled trial was conducted to collect patients with prolonged mechanical ventilation. Patients were randomly assigned to receive PAV+ or PSV as weaning mode. Weaning outcomes were compared between 2 groups.
Detailed Description
Pressure support ventilation (PSV) the most frequently used mode of ventilator support in intensive care units, but has several demerits. Proportional assist ventilation with load-adjustable gain factors (PAV+) is a promising mode with better patient synchrony and weaning advantages. However, weaning outcome of PAV+ in patients with prolonged mechanical ventilation has not been evaluated before. We conducted a prospective randomized controlled trial in a tertiary medical center. This study aimed to compare the effectiveness between PAV+ and PSV for weaning adult patients with prolonged mechanical ventilation.
