Abstract : Aim : To evaluate the influence of Acute Physiology and Chronic Health Evaluation (APACHE II) score on the choice of mechanical ventilation method and treatment outcome. Methods : A prospective, randomized trial was carried out at the multidisciplinary Intensive Care Unit over 22 months. Research sample consisted of 129 patients who required mechanical ventilation, divided in two groups : APACHE II 20 and APACHE II > 20. Both groups were than randomized for either noninvasive or invasive mechanical ventilation. Comparison was made based on patient characteristics, objective parameters and influence of APACHE II score on treatment success and failure. Results : APACHE II scoring was shown to have statistical significance on outcome assessment. Statistical significance was in favour of patients with APACHE II score 20 vs > 20 (ventilator associated pneumonia 0 vs. 10, tracheotomy 0 vs. 16, Intensive Care Unit mortality 0 vs 12). Furthermore, in the group with APACHE II score > 20, after randomization, there was a statistical significance in favour of noninvasive mechanical ventilation in need for tracheotomy 2 (4%) vs. 14 (28%) (p < 0.001). Conclusion : Using good patient selection and applying strict protocols, in the group of patients with APACHE II 20 all patients had successful mechanical ventilation, while in the group of patients with APACHE II > 20, noninvasive mechanical ventilation can be applied.

Noninvasive mechanical ventilation in acute hypoxaemic respiratory failure.
In acute hypoxaemic respiratory failure (HRF), oxygenation, reduction in the work of breathing and in dyspnoea may be achieved by delivering noninvasive mechanical ventilation (NIMV). Several uncontrolled and 13 randomized controlled studies (RCS) were reviewed. Uncontrolled studies confirmed the feasibility and the possibility to improve arterial blood oxygenation with NIMV. The 13 RCS compare...

Noninvasive ventilation (NIV) includes various techniques for augmenting alveolar ventilation without an endotracheal airway. The theoretical advantages of this approach include avoiding the complications associated with endotracheal intubation, improving patient comfort, preserving airway defence mechanisms, speech and swallowing. The successful application of NIV in hypoxaemic acute respirato...

For many decades, the primary treatment of acute respiratory failure has been mechanical ventilation. Intubation and mechanical ventilation carry complications such as upper respiratory system trauma, barotrauma, volutrauma, oxytrauma, atelectrauma, and nosocomial infection, and they increase mortality. Noninvasive mechanical ventilation (NIMV) applied to a specially selected group of patients ...

Noninvasive mechanical ventilation (NIMV) was created for patients who needed noninvasive ventilator support, this procedure decreases the complications associated with the use of endotracheal intubation (ETT). The application of NIMV has acquired major relevance in the last few years in the management of acute respiratory failure (ARF), in patients with hypoxemic and hypercapnic failure. The m...
متن کاملNoninvasive ventilation for post-pneumonectomy severe hypoxemia.
ARDS remains a lethal complication after major lung resections. The reported mortality ranges from 50% to 100%, with increased incidence and mortality rates in pneumonectomy patients. The pathogenesis of early ARDS is still not fully understood, and the majority of patients will require mechanical ventilation. A review of the literature reveals that the role of noninvasive ventilation (NIV) in...
