2 b Regional Intensive Care Unit , Royal Victoria Hospital , Belfast , UK. The acute respiratory distress syndrome (ARDS) is a common and catastrophic condition, with a high mortality rate and economic burden on society. Despite 50 years of study, there is no specific pharmacological therapy for ARDS.
Therapy
Acute respiratory distress syndrome ( ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis).

What antibiotics are used to treat ARDS?
Antimicrobials were prescribed in all the patients, as majority of the cases of ARDS were secondary to an infectious aetiology. The beta lactam antibiotics were the most commonly prescribed antimicrobials followed by doxycycline.
What methods are used for treatment of the patient with acute respiratory distress syndrome?
Treatment of ARDS is supportive and includes mechanical ventilation, prophylaxis for stress ulcers and venous thromboembolism, nutritional support, and treatment of the underlying injury. Low tidal volume and high positive end-expiratory pressure improve outcomes.
What is the treatment for acute respiratory failure?
Treatments for respiratory failure may include oxygen therapy, medicines, and procedures to help your lungs rest and heal. Chronic respiratory failure can often be treated at home. If you have serious chronic respiratory failure, you may need treatment in a long-term care center.
Can antibiotics treat ARDS?
Beyond their antibacterial activity, several antibiotics such as macrolides and tetracyclines exert pleiotropic immunomodulatory effects that might be able to rectify the dysregulated inflammatory response present in patients with ARDS.
What is management of respiratory distress?
Management of ARDS is largely focused on supportive management, lung-protective ventilation and minimizing iatrogenic forms of lung injury, with extracorporeal life support as an option for patients who continue to deteriorate despite these supportive therapies.
What is acute respiratory disease syndrome?
Acute respiratory distress syndrome (ARDS) is a serious lung condition that causes low blood oxygen. People who develop ARDS are usually ill due to another disease or a major injury. In ARDS, fluid builds up inside the tiny air sacs of the lungs, and surfactant breaks down.
Why are diuretics used in ARDS?
Diuretics are frequently administered to critically ill patients to alleviate pulmonary edema and may reduce lung injury (4). Several studies have involved diuretics as part of therapeutic intervention for ARDS, but whether they could reduce mortality has not been conclusively determined.
How can acute respiratory distress syndrome be prevented?
There's no way to prevent ARDS completely. However, you may be able to lower your risk of ARDS by doing the following: Seek prompt medical assistance for any trauma, infection, or illness. If you smoke, consider stopping smoking cigarettes.
How does PEEP help in ARDS?
The rationale for the application of PEEP during mechanical ventilation of the lungs of patients with ARDS is to prevent alveolar collapse, reducing injurious alveolar shear stresses and improving ventilation–perfusion matching, and thus, arterial oxygenation.
How do drugs help with ARDS?
Drugs may help to repair damage to the lung injury, or limit the body's response to the injury (for example, by reducing any excess fluid that may collect around the injured lungs).
What are the different types of drugs?
For the main comparisons in this review, we included five types of drugs: corticosteroids, surfactants, N-acetylcysteine, statins, and beta-agonists. These were compared to placebo or to standard care.
What is ARDS in medical terms?
ARDS is a life-threatening condition caused by injury to the lungs, for example from infections such as pneumonia or sepsis, or from trauma. People with ARDS are cared for in an intensive care unit, and need support with breathing from mechanical ventilation.
How many RCTs included ARDS?
We included 48 RCTs with 6299 participants who had ARDS; two included only participants with mild ARDS (also called acute lung injury). Most studies included causes of ARDS that were both direct and indirect injuries. We noted differences between studies, for example the time of administration or the size of dose, and because of unclear reporting we were uncertain whether all studies had used equivalent lung protection strategies.
Do corticosteroids cause early death?
Although corticosteroids may reduce the number of people who die within the first three months, and beta-agonists probably slightly increase these early deaths, we found both an increase and a reduction in deaths in our analyses for these drugs. We found no evidence that surfactants, N-acetylcysteine, or statins made a difference to the number of people who died within three months. Only two studies (one that assessed steroids, and one surfactants) reported deaths later than three months, but evidence for this was uncertain.
Do corticosteroids reduce all-cause mortality?
Corticosteroids may reduce all-cause mortality within three months by 86 per 1000 patients (with as many as 161 fewer to 19 more deaths); however, the 95% confidence interval (CI) includes the possibility of both increased and reduced deaths (risk ratio (RR) 0.77, 95% CI 0.57 to 1.05; 6 studies, 574 participants; low-certainty evidence). Due to the very low-certainty evidence, we are uncertain whether corticosteroids make little or no difference to late all-cause mortality (later than three months) (RR 0.99, 95% CI 0.64 to 1.52; 1 study, 180 participants), or to the duration of mechanical ventilation (mean difference (MD) −4.30, 95% CI −9.72 to 1.12; 3 studies, 277 participants). We found that ventilator-free days up to day 28 (VFD) may be improved with corticosteroids (MD 4.09, 95% CI 1.74 to 6.44; 4 studies, 494 participants; low-certainty evidence). No studies reported adverse events leading to discontinuation of study medication, or fitness to return to work at 12 months (FTR).
Do beta agonists help with ventilator free days?
We found that steroids may improve the number of days that people do not need mechanical ventilation (ventilator-free days up to day 28), but that beta-agonists may not improve ventilator-free days (although we were uncertain about the evidence for beta-agonists).
What are the therapies used for ARDS?
Widely available therapies, and those studied in large clinical trials, include neuromuscular blockade, corticosteroids, and inhaled pulmonary vasodilators. These therapies are frequently used in the clinical setting, despite a lack of strong evidence favoring their use in ARDS. We examine each here, in the context of underlying pathophysiology.
What is the target RASS of unblinded control group sedation?
Unblinded—control group sedation strategy was either to target RASS of –1 to 0, or to perform daily awakenings
How long has ARDS been around?
Over 50 years have passed since the acute respiratory distress syndrome (ARDS) was first described.1Despite the passage of more than one-half of a century, almost all of ARDS care continues to be supportive in nature, and mortality remains high at 34% to 45%.2As our understanding of ARDS pathophysiology has improved, a number of pharmacologic interventions have been tested, including those targeting ventilator-associated lung injury (VALI), dead space ventilation, inflammation, alveolar epithelial and capillary endothelial injury, and dysfunctional fluid clearance. Although no medications have yet demonstrated a clear mortality benefit in ARDS, a number of therapies are currently being evaluated in clinical trials (Table 1). In this article, we review selected pharmacologic treatments for ARDS.
How do corticosteroids work?
They act by binding to cell-surface receptors, and then translocate to the cell nucleus, where they inhibit the synthesis of proinflammatory mediators, such as cytokines, chemokines, inflammatory enzymes, receptors, and proteins.17 Corticosteroids are widely administered to patients with ARDS, both for the management of ARDS or for concurrent conditions such as septic shock or pneumonia. In a large US cohort, 44% of patients with moderate-to-severe ARDS received corticosteroids.18However, the benefit of steroids in ARDS remains unclear, despite a number of studies assessing their use in ARDS and ARDS-related conditions (Table 3).
What are the pathologic features of ARDS?
The pathologic features of ARDS include a marked acute inflammatory response precipitated by alveolar epithelial and capillary endothelial injury.16Process es that trigger ARDS, such as sepsis and pancreatitis, are frequently inflammatory themselves, as is VALI, often a consequence of supportive care for ARDS with mechanical ventilation.
Is respiratory distress a heterogeneous disease?
Acute respiratory distress syndrome is a heterogenous syndrome with many etiologies for which there are no definitive pharmacologic treatments, despite decades of research. We explore some adjunctive pharmacologic therapies, including neuromuscular blockade, corticosteroids, and inhaled pulmonary vasodilators. Additionally, we explore some investigative therapies, including Vitamin C, beta-agonists, statins, mesenchymal stromal cells, and granulocyte–macrophage colony stimulating factor. We do discuss the potential role of steroids in acute respiratory distress syndrome with severe acute respiratory syndrome coronavirus 2 as a trigger. The standard of care, however, remains supportive care.
Does ventilator free days impact mortality?
No impact on mortality or ventilator-free days
