Biphasic cuirass ventilation in the escalation of non-invasive ventilation in COVID-19: Case report and review.

Ventilatory alternatives to prolong noninvasive ventilation in COVID-19 patients are attractive and poorly understood. New devices to deliver negative noninvasive ventilation as biphasic cuirass ventilation (BCV) have been introduced. BCV device assist in spontaneous breathing and support ventilation. We describe a case of the combination of BCV with high-flow nasal oxygenation (HFNO) in the treatment of a COVID-19 pneumonia patient that required prolonged NIV leading to face mask intolerance, ventilator dependency secondary to residual lung fibrosis and respiratory muscular weakness. BCV provides an efficient non-invasive approach in de-escalation of therapy and weaning of prolonged NIV.

An updated HACOR score for predicting the failure of noninvasive ventilation: a multicenter prospective observational study.

BACKGROUND: Heart rate, acidosis, consciousness, oxygenation, and respiratory rate (HACOR) have been used to predict noninvasive ventilation (NIV) failure. However, the HACOR score fails to consider baseline data. Here, we aimed to update the HACOR score to take into account baseline data and test its predictive power for NIV failure primarily after 1-2 h of NIV. METHODS: A multicenter prospective observational study was performed in 18 hospitals in China and Turkey. Patients who received NIV because of hypoxemic respiratory failure were enrolled. In Chongqing, China, 1451 patients were enrolled in the training cohort. Outside of Chongqing, another 728 patients were enrolled in the external validation cohort. RESULTS: Before NIV, the presence of pneumonia, cardiogenic pulmonary edema, pulmonary ARDS, immunosuppression, or septic shock and the SOFA score were strongly associated with NIV failure. These six variables as baseline data were added to the original HACOR score. The AUCs for predicting NIV failure were 0.85 (95% CI 0.84-0.87) and 0.78 (0.75-0.81) tested with the updated HACOR score assessed after 1-2 h of NIV in the training and validation cohorts, respectively. A higher AUC was observed when it was tested with the updated HACOR score compared to the original HACOR score in the training cohort (0.85 vs. 0.80, 0.86 vs. 0.81, and 0.85 vs. 0.82 after 1-2, 12, and 24 h of NIV, respectively; all p values < 0.01). Similar results were found in the validation cohort (0.78 vs. 0.71, 0.79 vs. 0.74, and 0.81 vs. 0.76, respectively; all p values < 0.01). When 7, 10.5, and 14 points of the updated HACOR score were used as cutoff values, the probability of NIV failure was 25%, 50%, and 75%, respectively. Among patients with updated HACOR scores of ≤ 7, 7.5-10.5, 11-14, and > 14 after 1-2 h of NIV, the rate of NIV failure was 12.4%, 38.2%, 67.1%, and 83.7%, respectively. CONCLUSIONS: The updated HACOR score has high predictive power for NIV failure in patients with hypoxemic respiratory failure. It can be used to help in decision-making when NIV is used.

Role of Sedation and Analgesia during Noninvasive Ventilation: Systematic Review of Recent Evidence and Recommendations.

Aim: This systematic review aimed to investigate the drugs used and their potential effect on noninvasive ventilation (NIV). Background: NIV is used increasingly in acute respiratory failure (ARF). Sedation and analgesia are potentially beneficial in NIV, but they can have a deleterious impact. Proper guidelines to specifically address this issue and the recommendations for or against it are scarce in the literature. In the most recent guidelines published in 2017 by the European Respiratory Society/American Thoracic Society (ERS/ATS) relating to NIV use in patients having ARF, the well-defined recommendation on the selective use of sedation and analgesia is missing. Nevertheless, some national guidelines suggested using sedation for agitation. Methods: Electronic databases (PubMed/Medline, Google Scholar, and Cochrane library) from January 1999 to December 2019 were searched systematically for research articles related to sedation and analgosedation in NIV. A brief review of the existing literature related to sedation and analgesia was also done. Review results: Sixteen articles (five randomized trials) were analyzed. Other trials, guidelines, and reviews published over the last two decades were also discussed. The present review analysis suggests dexmedetomidine as the emerging sedative agent of choice based on the most recent trials because of better efficacy with an improved and predictable cardiorespiratory profile. Conclusion: Current evidence suggests that sedation has a potentially beneficial role in patients at risk of NIV failure due to interface intolerance, anxiety, and pain. However, more randomized controlled trials are needed to comment on this issue and formulate strong evidence-based recommendations.

Ocular disorders in non-invasive ventilation and CPAP therapy-A case report.

BACKGROUND: The benefits of non-invasive ventilation (NIV) in the treatment of several chronic and acute disorders are well documented. However, the side effects associated with this type of treatment must always be taken into account. Patients often fail to mention ocular symptoms. CLINICAL CASE: A male, 80 years old, autonomous in activities of daily living, with a personal history of chronic obstructive pulmonary disease (COPD) and chronic hypercapnic respiratory failure was admitted to the emergency room due to dyspnea and a depressed level of consciousness. The patient deteriorated to severe respiratory acidosis and was started on NIV. On the third day of admission there was note of significant ocular irritation in addition to a dermal lesion on the bridge of the nose. Ophthalmology reported a corneal ulcer and bilateral conjunctivitis and prescribed topical antibiotic and steroids, with improvement of the symptoms. DISCUSSION: Ocular disorders in relation with NIV are more common than documented in clinical practice. It's essential that every professional that deals with this type of therapy is sensitive to the recognition and early diagnosis of this secondary effect, motivating timely evaluation. This case exemplifies the rapid onset of this type of complication, especially if the staff is poorly trained in NIV application and in patients with a decreased level of consciousness. Centers need to develop protocols to evaluate patients under NIV for ocular symptoms, with the goal of early therapeutic intervention. The creation and divulgation of these procedures will drastically improve the quality of care to acute and chronic patients in need of NIV.

Secretion management in patients with ineffective airway clearance with non-invasive mechanical ventilation use: Expert guidance for clinical practice.

Non-invasive ventilation (NIV) is a mainstay of management of chronic respiratory failure in many disorders which are known to cause abnormal airway secretion clearance. Currently, there is no guidance regarding either the secretion handling during NIV use or the role of NIV in secretion management in these patients. The aim of this document was to provide an overview of the various techniques available in the management of respiratory secretions and their use in conjunction with NIV. Literature search was performed using the keywords, "(secretion OR secretions) AND (noninvasive ventilation OR NIV)" on PubMed and EMBASE. The search yielded 1681 and 509 titles from PubMed and EMBASE, respectively. After screening, 19 articles were included in this review. Suggestions of the expert panel were formulated by mutual consensus after reviewing the relevant literature. The draft of the expert panel's suggestions was circulated among all authors via electronic mail for comments. Any conflicts were resolved by mutual discussion to achieve agreement. The final document was approved by all. This document by the International Network for Airway Secretions Management in NIV describes various airway secretion clearance techniques. It provides the expert panel's suggestions for the use of these techniques in conjunction with NIV for patients with muco-obstructive and neuromuscular disorders.

Exercise and Chronic Obstructive Pulmonary Disease (COPD).

Systemic effects of COPD lead to cardiovascular co-morbidities, muscle wasting and osteoporosis that, in turn, lead to inactivity and physical deconditioning. This evolution has a direct influence on the health-related quality of life (HRQoL) of patients suffering from this respiratory disease. Pharmacological therapy leads to improvement in shortness of breath, but it has a limited effect on the physical deconditioning. Pulmonary rehabilitation relieves dyspnoea and fatigue, improves emotional function and enhances the sense of control that individuals have over their condition. These improvements are moderately substantial and clinically significant. Rehabilitation serves as an essential component of the management of COPD and is beneficial in improving health-related quality of life and exercise capacity.
