"Prone ventilation" "ARDS"

Influenza pandemics are unpredictable recurrent events with global health, economic, and social consequences. The objective of this review is to provide an update on the latest developments in early diagnosis and specific treatment of the disease and its complications, particularly with regard to respiratory organ failure. Despite advances in treatment, the rate of mortality in the intensive care unit remains approximately 30%. Therefore, early identification of potentially severe viral pneumonia is extremely important to optimize treatment in these patients...

There is very limited evidence regarding the use of prone position as part of the treatment of severe ARDS in pregnant patients. Currently, recommendations for invasive ventilatory management in this population are very scarce and are based on the extrapolation of conclusions obtained in studies of non-pregnant patients. The available literature asserts that the anatomy and physiology of the pregnant woman undergoes complex adaptive changes that must be considered during invasive ventilatory support and prone position...

OBJECTIVE: Prone positioning has been found to improve oxygenation in most patients with acute respiratory distress syndrome (ARDS). The study aimed to investigate the effectiveness of the prone position in patients with ARDS. PATIENTS AND METHODS: The prone position is one of the ventilator techniques included in recent guidelines for acute respiratory distress syndrome. This study was a retrospective evaluation of the records of 100 ARDS patients who were administered prone position mechanical ventilation in our intensive care unit...

Background: Prone position ventilation (PPV) can significantly improve oxygenation index and blood oxygen saturation in most (70%-80%) patients with acute respiratory distress syndrome. However, although PPV is not an invasive procedure, there are many potential PPV-related complications, such as nerve compression, crush injury, venous stasis (e.g., facial oedema), pressure sores, retinal damage, vomiting, and arrhythmia, with an incidence of up to 56.9%. Nursing managers have focused on reducing the occurrence of PPV-related complications and improving safety...

BACKGROUND: Evaluation of the efficacy and safety of mechanical ventilation settings is a cornerstone of the early phase of the management of acute respiratory distress syndrome (ARDS). This study aimed to evaluate the adherence to currently recommended lung-protective ventilator strategies (tidal volume, plateau pressure, driving pressure, prone positioning, and positive end-expiratory pressure [PEEP]) for adults with moderate-to-severe ARDS in a tertiary care setup, thereby evaluating if lung-protective ventilation is associated with improved outcomes...

BACKGROUND: Awake prone positioning (APP) is a recommended therapy for non-intubated ARDS patients, but adherence can be challenging. Understanding the barriers and facilitators of adherence to APP is essential to increase the adherence of therapy and improve patient outcomes. The objective of this study was to explore the barriers and facilitators of adherence to awake prone ventilation using a qualitative approach and the Capability, Opportunity, Motivation-Behavior (COM-B) model. METHODS: Semi-structured, in-depth interviews were conducted with patients involved in awake prone ventilation...

INTRODUCTION: During the coronavirus pandemic (COVID -19), the use of prone positioning in critically ill patients with acute respiratory distress syndrome (ARDS) increased substantially. As a result, clinicians had to (re)learn how to treat the patient in the prone position while preventing adverse events such as pressure ulcers, skin tears and moisture-associated skin damage. AIM: The purpose of the study was to determine participants' learning needs related to patients in the prone position and the prevention of skin damage, such as pressure ulcers, and what they perceived as a positive or negative learning experience...

Ventilation in a prone position (PP) for 12 to 16 h per day improves survival in ARDS. However, the optimal duration of the intervention is unknown. We performed a prospective observational study to compare the efficacy and safety of a prolonged PP protocol with conventional prone ventilation in COVID-19-associated ARDS. Prone position was undertaken if P/F < 150 with FiO2 > 0.6 and PEEP > 10 cm H2 O. Oxygenation parameters and respiratory mechanics were recorded before the first PP cycle, at the end of the PP cycle and 4 h after supination...

BACKGROUND: Venovenous extracorporeal membrane oxygenation (VV-ECMO) has been widely used in treating patients with coronavirus disease 2019 (COVID-19) with severe respiratory failure. However, there are few reports of the successful treatment of patients with massive airway hemorrhage in severe COVID-19 during VV-ECMO treatment. METHODS: We analyzed the treatment process of a patient with a massive airway hemorrhage in severe COVID-19, who underwent prolonged VV-ECMO treatment...

Prone ventilation is an effective and increasingly utilised tool in the management of Acute Respiratory Distress Syndrome (ARDS), a common sequela of COVID-19 infection. However, its use is associated with a significant risk of pressure ulcers. We report a unique case of prone positioning, catheter-related penile pressure ulcer. Clinical awareness, early recognition and regular repositioning is crucial in the prevention of this complication.

BACKGROUND: High mortality due to COVID-19 disease has been a serious concern, a few of the causes being disseminated intravascular coagulation (DIC) and venous thromboembolism. Considering this, some experts have used heparin. However, its role still needs to be validated. MATERIALS AND METHODS: This study predicts the role of nebulized heparin in decreasing the severity of lung injury caused by COVID-19. Thirty patients admitted with COVID-19 acute respiratory distress syndrome (ARDS) in the intensive care unit (ICU) of All India Institute of Medical Sciences, Rishikesh, were included in this study, which was conducted over a period of 3 months...

BACKGROUND: Researchers have tried unsuccessfully for many years using randomized controlled trials to show the efficacy of prone ventilation in treating ARDS. These failed attempts were of use in designing the successful PROSEVA trial, published in 2013. However, the evidence provided by meta-analyses in support of prone ventilation for ARDS was too low to be conclusive. The present study shows that meta-analysis is indeed not the best approach for the assessment of evidence as to the efficacy of prone ventilation...

BACKGROUND: Prone position ventilation (PPV) has been recommended for patients with acute respiratory distress syndrome (ARDS) to improve oxygenation. However, whether prolonged prone ventilation will aggravate hyperoxia and whether abdominal compression will aggravate permissive hypercapnia acidosis are topics of concern. We carried out a retrospective analysis to investigate the issues above. METHODS: Clinical data were collected from 97 moderate-to-severe ARDS patients who received PPV as part of their treatment in the intensive care unit (ICU) of the First Affiliated Hospital of Guangzhou Medical University from November 2015 to May 2021...

BACKGROUND: Aortic dissection is a complex and dangerous cardiovascular disease, with many complications in the perioperative period, including severe acute respiratory distress syndrome (ARDS), which affects prognosis and increases mortality. Despite the effect of prone positioning (PP) in improving oxygenation in patients with severe ARDS, reports about PP early after cardiac surgery are few and such an option may be an issue in cardiac surgery patients because of the recent sternotomy...

BACKGROUND: Acute respiratory distress syndrome (ARDS) is a very common disease in the intensive care unit (ICU), with rapid progression and high mortality. Infections caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can easily progress to ARDS in severely ill patients. Early and rapid diagnosis as well as screening for ARDS during treatment is very important. Owing to the particularity of patients with coronavirus disease 2019 (COVID-19), computed tomography (CT) examination is not always possible, and chest radiographs have a low sensitivity and specificity for the diagnosis of lung diseases...

The Coronavirus disease (COVID-19) pandemic of 2019 has resulted in significant morbidity and mortality, especially from severe acute respiratory distress syndrome (ARDS). As of September 2022, more than 6.5 million patients have died globally, and up to 5% required intensive care unit treatment. COVID-19-associated ARDS (CARDS) differs from the typical ARDS due to distinct pathology involving the pulmonary vasculature endothelium, resulting in diffuse thrombi in the pulmonary circulation and impaired gas exchange...

PURPOSE OF REVIEW: To summarize pathophysiology, key conflicts, and therapeutic approaches in managing concomitant severe acute brain injury (SABI) and acute respiratory distress syndrome (ARDS). RECENT FINDINGS: ARDS is common in SABI and independently associated with worse outcomes in all SABI subtypes. Most landmark ARDS trials excluded patients with SABI, and evidence to guide decisions is limited in this population. Potential areas of conflict in the management of patients with both SABI and ARDS are (1) risk of intracranial pressure (ICP) elevation with high levels of positive end-expiratory pressure (PEEP), permissive hypercapnia due to lung protective ventilation (LPV), or prone ventilation; (2) balancing a conservative fluid management strategy with ensuring adequate cerebral perfusion, particularly in patients with symptomatic vasospasm or impaired cerebrovascular blood flow; and (3) uncertainty about the benefit and harm of corticosteroids in this population, with a mortality benefit in ARDS, increased mortality shown in TBI, and conflicting data in other SABI subtypes...

BACKGROUND: The efficacy and safety profiles of prone ventilation among intubated Coronavirus Disease 2019 (COVID-19) patients remain unclear. The primary objective was to examine the effect of prone ventilation on the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2 /FiO2 ) in intubated COVID-19 patients. METHODS: Databases of MEDLINE, EMBASE and CENTRAL were systematically searched from inception until March 2021. Case reports and case series were excluded...

The mortality of acute respiratory distress syndrome (ARDS) patients is very high, veno-venous extracorporeal membrane oxygenation (VV-ECMO) has been proved to improve the prognosis of these patients, but the maximization of this benefit relies on the appropriate mechanical ventilation strategy; with the new research evidence arise, scholars have reached a certain consensus on how to implement mechanical ventilation in ARDS patients supported by VV-ECMO, but there are still many controversies. Based on the evidences of current researches and clinical experiences, this article analyzes the hot issues of mechanical ventilation strategy for these patients, including the implementation of early 'overprotective' ventilation strategy, whether spontaneous breathing allowed, prone ventilation and ventilator weaning...

BACKGROUND: The physiological effects of prone ventilation in ARDS patients have been discussed for a long time but have not been fully elucidated. Electrical impedance tomography (EIT) has emerged as a tool for bedside monitoring of pulmonary ventilation and perfusion, allowing the opportunity to obtain data. This study aimed to investigate the effect of prone positioning (PP) on ventilation-perfusion matching by contrast-enhanced EIT in patients with ARDS. DESIGN: Monocenter prospective physiologic study...
