Randomized Controlled Trial Multicenter StudyEffects of early administration of acetazolamide on the duration of mechanical ventilation in patients with chronic obstructive pulmonary disease or obesity-hypoventilation syndrome with metabolic alkalosis. A randomized trial.
Metabolic alkalosis (MA) inhibits respiratory drive and may delay weaning from mechanical ventilation (MV). MA is common in CO2-retainer patients that need MV. Acetazolamide (ACTZ) decreases serum bicarbonate concentration and stimulates respiratory drive. This study evaluated the effects of ACTZ on the duration of MV in patients with MA and COPD or obesity hypoventilation syndrome (OHS) intubated with acute respiratory failure. ⋯ Among patients with MA and COPD or OHS, early treatment with ACTZ did not shorten significantly the duration of MV compared with placebo.

Multicenter StudyVariation in extubation failure rates after neonatal congenital heart surgery across Pediatric Cardiac Critical Care Consortium hospitals.
In a multicenter cohort of neonates recovering from cardiac surgery, we sought to describe the epidemiology of extubation failure and its variability across centers, identify risk factors, and determine its impact on outcomes. ⋯ This multicenter study showed that 11% of neonates recovering from cardiac surgery fail initial postoperative extubation. Only congenital airway anomaly was independently associated with extubation failure. We observed a 4-fold variation in extubation failure rates across hospitals, suggesting a role for collaborative quality improvement to optimize outcomes.

Randomized Controlled Trial Multicenter Study Comparative Study
Protective intraoperative ventilation with higher versus lower levels of positive end-expiratory pressure in obese patients (PROBESE): study protocol for a randomized controlled trial.
Postoperative pulmonary complications (PPCs) increase the morbidity and mortality of surgery in obese patients. High levels of positive end-expiratory pressure (PEEP) with lung recruitment maneuvers may improve intraoperative respiratory function, but they can also compromise hemodynamics, and the effects on PPCs are uncertain. We hypothesized that intraoperative mechanical ventilation using high PEEP with periodic recruitment maneuvers, as compared with low PEEP without recruitment maneuvers, prevents PPCs in obese patients. ⋯ To our knowledge, the PROBESE trial is the first multicenter, international randomized controlled trial to compare the effects of two different levels of intraoperative PEEP during protective low tidal volume ventilation on PPCs in obese patients. The results of the PROBESE trial will support anesthesiologists in their decision to choose a certain PEEP level during general anesthesia for surgery in obese patients in an attempt to prevent PPCs.

Multicenter Study Observational StudyEpidemiology of Weaning Outcome According to a New Definition. The WIND Study.
The weaning process concerns all patients receiving mechanical ventilation. A previous classification into simple, prolonged, and difficult weaning ignored weaning failure and presupposed the use of spontaneous breathing trials. ⋯ A new classification allows us to categorize all weaning situations. Every additional day without a weaning success after the first separation attempt increases the risk of dying.

Randomized Controlled Trial Multicenter Study
Use of noninvasive and invasive mechanical ventilation in cardiogenic shock: A prospective multicenter study.
Despite scarce data, invasive mechanical ventilation (MV) is widely recommended over non-invasive ventilation (NIV) for ventilatory support in cardiogenic shock (CS). We assessed the real-life use of different ventilation strategies in CS and their influence on outcome focusing on the use of NIV and MV. ⋯ Although MV is generally recommended mode of ventilatory support in CS, a fair number of patients were successfully treated with NIV. Moreover, ventilation strategy was not associated with outcome. Thus, NIV seems a safe option for properly chosen CS patients.
