AI Article Synopsis
- A study evaluated the effectiveness of noninvasive ventilation (NIV) in 72 postoperative patients experiencing acute respiratory failure (ARF).
- Out of these patients, 58% successfully avoided intubation after using NIV, and factors like decreased oxygen levels and higher illness severity scores were linked to NIV failure.
- The findings suggest that while NIV can be beneficial for postoperative ARF patients, the presence of nosocomial pneumonia is a key predictor of its failure.
Article Abstract
Background And Objective: Few data are available on the efficacy of noninvasive ventilation (NIV) in postoperative patients with acute respiratory failure (ARF).
Methods: Seventy-two patients coming from the surgical wards with postoperative ARF were retrospectively evaluated. The major characteristics of patients who were intubated were compared with the characteristics of those who were not after a trial of NIV. Predictive factors for failure of NIV were analysed.
Results: Out of 72 patients with ARF after surgery who were treated with NIV, 42 avoided intubation (58%). On a univariate analysis, a decrease in the paO2/FiO2 ratio after 1 h of NIV (223 +/- 84 to 160 +/- 68 mmHg, P < 0.05) was associated with NIV failure and need for tracheal intubation because of nosocomial pneumonia and an increased simplified acute physiology score (SAPS) 2. In a multivariate analysis, nosocomial pneumonia [odds ratio (OR) 4.189; 95% confidence interval (CI) 1.383-12.687] and SAPS 2 higher than 35 (OR 4.969; 95% CI 1.627-15.172) were independent predictive factors of NIV failure. NIV success was associated with a reduced ICU stay (16.8 vs. 26.1 days, P < 0.001).
Conclusion: NIV could be considered in postoperative patients who presented with ARF. Nosocomial pneumonia is predictive of NIV failure.

: Non-invasive ventilation (NIV) has emerged as a possible first-step treatment to avoid invasive intubation in pediatric intensive care units (PICUs) due to its advantages in reducing intubation-associated risks. However, the timely identification of NIV failure is crucial to prevent adverse outcomes. This study aims to identify predictors of first-attempt NIV failure in PICU patients by testing various machine learning techniques and comparing their predictive abilities.

Background: Non-invasive ventilation (NIV) uses positive pressure to assist people with respiratory muscle weakness or severe respiratory compromise to breathe. Most people use this treatment during sleep when breathing is most susceptible to instability. The benefits of using NIV in motor neurone disease (MND) are well-established.

Article Synopsis
- The study aimed to identify factors influencing CPAP failure rates in patients with COVID-19-related hypoxemia, analyzing 200 ICU patients in southwestern Iran.
- Results showed a high CPAP failure rate (78.5%), particularly linked to higher HACOR scores, diabetes mellitus, older age, obesity, and elevated Blood Urea Nitrogen levels.
- The findings suggest that specific clinical factors such as HACOR scores and comorbidities significantly impact the effectiveness of CPAP therapy in these patients.

Background: The impact of noninvasive ventilation (NIV) managed outside the intensive care unit in patients with early acute respiratory failure remains unclear. We aimed to determine whether adding early NIV prevents the progression to severe respiratory failure.
Methods: In this multinational, randomised, open-label controlled trial, adults with mild acute respiratory failure (arterial oxygen partial pressure/fraction of inspiratory oxygen [Pao/FiO] ratio ≥200) were enrolled across 11 hospitals in Italy, Greece, and Kazakhstan.
Effect of Flow Rates of High-flow Nasal Cannula on Extubation Outcomes: A Randomized Controlled Trial.
Chest
December 2024
From the Division of Pulmonary and Critical Care Medicine, National Taiwan University Hospital, Taipei, Taiwan. Electronic address:
Background: High-flow nasal cannula (HFNC) has emerged as a promising intervention for post-extubation oxygen therapy, with the potential to reduce the need for reintubation. However, it remains unclear whether using a higher flow setting provides better outcomes than the commonly used flow rate of 30-50 L/min.
Research Question: Does setting the flow rate of HFNC at 60 L/min versus 40 L/min for post-extubation care result in different extubation outcomes?
Study Design And Methods: This randomized controlled trial assigned intubated patients to receive HFNC at either a 60 L/min or 40 L/min flow rate following extubation.
