An adjuvant for the acute respiratory distress syndrome (ARDS) is any intervention, in addition to or instead of mechanical ventilation, that is used to facilitate gas exchange or enhance compliance with lung protective ventilation (Table 1). Pharmacologic adjuvants have been the focus of many studies for years and include diuretics, corticosteroids, neuromuscular blocking agents, and inhaled pulmonary vasodilators. Non-pharmacologic agents include prone positioning, high frequency oscillatory ventilation, and extracorporeal life support. These non-pharmacologic options have been the focus of many large trials in recent years. This paper discusses the relative efficacy of these adjuvants and reviews their current use.

Diuretics
|
39 % of patients with ARDS (single-center retrospective study) [4]
Survey of intensivists: 70 % reported use [3]
|
Corticosteroids
|
70 % of UK physicians surveyed used corticosteroids in ARDS: Of these, 30 % reported initiating early in ARDS (≤7 days), 53 % reported initiating late in ARDS (>7 days) [9]
LUNG SAFEa: 17.3 % reported use across all ARDS, 23.3 % severe ARDS [10]
|
Continuous neuromuscular blocking agents
|
(Post-Papazian trial): LUNG SAFE: 37.8 % severe ARDS [10]
|
Inhaled nitric oxide
|
LUNG SAFE: 7.7 % reported useb across all ARDS, 13.0 % severe ARDS [10]
|
Non-pharmacologic

|
Prone positioning
|
(Post-Guerin trial) LUNG SAFE: 7.9 % across all ARDS, 16.3 % severe ARDS [10]
|
High frequency oscillatory ventilation
|
(Post-Ferguson/Young trials): LUNG SAFE: 1.5 % severe ARDS [10]
|
Extracorporeal membrane oxygenation
|
12-fold increase in rate of use over the past decade (2004–2014) [23]
LUNG SAFE: 3.2 % across all ARDS, 6.6 % severe ARDS [10]
