P208 The use of non-invasive ventilation in patients with community acquired pneumonia admitted to the intensive care unit

This study of ventilated patients investigated pneumonia risk factors and outcome predictors in 476 episodes of pneumonia (48% community-acquired pneumonia, 24% hospital-acquired pneumonia, 28% ventilator-associated pneumonia) using a prospective survey in 14 intensive care units within Australia and New Zealand. For community acquired pneumonia, mortality increased with immunosuppression (OR 5.32, CI 95% 1.58–17.99, P<0.01), clinical signs of consolidation (OR 2.43, CI 95% 1.09–5.44, P=0.03) and Sepsis-Related Organ Failure Assessment (SOFA) scores (OR 1.19, CI 95% 1.08–1.30, P<0.001) but improved if appropriate antibiotic changes were made within three days of intensive care unit admission (OR 0.42, CI 95% 0.20–0.86, P=0.02). For hospital-acquired pneumonia, immunosuppression (OR 6.98, CI 95% 1.16–42.2, P=0.03) and non-metastatic cancer (OR 3.78, CI 95% 1.20–11.93, P=0.02) were the principal mortality predictors. Alcoholism (OR 7.80, CI 95% 1.20–17.50, P<0.001), high SOFA scores (OR 1.44, CI 95% 1.20–1.75, P=0.001) and the isolation of “high risk” organisms including Pseudomonas aeruginosa, Acinetobacter spp, Stenotrophomonas spp and methicillin resistant Staphylococcus aureus (OR 4.79, CI 95% 1.43–16.03, P=0.01), were associated with increased mortality in ventilator-associated pneumonia. The use of non-invasive ventilation was independently protective against mortality for patients with community-acquired and hospital-acquired pneumonia (OR 0.35, CI 95% 0.18–0.68, P=0.002). Mortality was similar for patients requiring both invasive and non-invasive ventilation and non-invasive ventilation alone (21% compared with 20% respectively, P=0.56). Pneumonia risks and mortality predictors in Australian and New Zealand ICUs vary with pneumonia type. A history of alcoholism is a major risk factor for mortality in ventilator-associated pneumonia, greater in magnitude than the mortality effect of immunosuppression in hospital-acquired pneumonia or community-acquired pneumonia. Non-invasive ventilation is associated with reduced ICU mortality. Clinical signs of consolidation worsen, while rationalising antibiotic therapy within three days of ICU admission improves mortality for community-acquired pneumonia patients.

Non Invasive Ventilation

Introduction: Acute respiratory failure is a common cause of Intensive care Unit admission for cancer patients. Non-invasive ventilation comes in between the two extreme situations: either provide only oxygen or ventilate invasively. This study was done to find the usefulness and efficacy of non-invasive ventilation in a cancer patient. Materials and Methods: A cross-sectional study was done at Nepal Cancer Hospital. Data analysis of patients requiring non-invasive ventilation at the Intensive care Unit from April 14, 2018, to April 13, 2019, were included. Results: Among 68 studied patients, the primary reason for the initiation of non-invasive ventilation sepsis (16.32%), pneumonia (10.88%), and lung cancer (10.2%). Postoperative atelectasis, pulmonary edema, and morphine overdose were associated with good respiratory improvement and Intensive care Unit survival (100%, 75% and 66.67% respectively). Respiratory failure with carcinoma lung, lung fibrosis, acute respiratory distress syndrome, terminally ill patients, and patients with low Glasgow Coma Scale had high failure rates (Survival: 13.33%, 14.29%, 16.67%, 0%, and 20% respectively). Conclusions: Non-invasive ventilation seems to be an effective way of ventilation for cancer patients. The selection of patients and timely initiation of non-invasive ventilation is of utmost importance for a better outcome.

The One

The development of medical technologies and the emergence of new methods of respiratory support with extensive capabilities to control positive pressure on the inhale and exhale made it possible to implement non-invasive ventilation. The integration of microprocessors in modern respiratory interfaces, on the one hand, and a deeper understanding of the mechanisms of the pathogenesis of respiratory failure, on the other hand, made it possible to improve and implement various methods of non-invasive respiratory support in everyday clinical practice. The experience gained in recent decades with the use of non-invasive ventilation made it possible to widely use this method of respiratory support in a wide variety of clinical situations. However, the selection of patients for mask ventilation, the choice of method and algorithm for its application, prognosis of effectiveness, prevention of negative effects, as before, remain relevant. This dictates the need to continue studying the clinical efficacy of non-invasive ventilation in patients with respiratory failure of various origins. The review presents the possibilities and limitations of the use of non-invasive respiratory support in patients with respiratory failure in the intensive care unit.
