The emergence of computed tomography imaging more than 25 years ago led to characterization of acute respiratory distress syndrome (ARDS) as areas of relatively normal lung parenchyma juxtaposed with areas of dense consolidation and atelectasis. Given that this heterogeneity is often dorsally distributed, investigators questioned whether care for ARDS patients in the prone position would lead to improved mortality outcomes. This clinical review discusses the physiological rationale and clinical evidence supporting prone positioning in treating ARDS, in addition to its complications and contraindications.

Acute respiratory distress syndrome (ARDS) due to coronavirus disease 2019 (COVID-19) pneumonia is the main cause of the pandemic’s death toll. The assessment of ARDS and time on invasive mechanical ventilation (IMV) could enhance the characterization of outcomes and management of this condition. This is a city-wide retrospective study of hospitalized patients with COVID-19 pneumonia from 5 March 2020 to 30 June 2020. Patients with critical illness were compared with those with non-critical illness. We examined the severity of ARDS and other factors associated with (i) weaning patients off IMV and (ii) mortality in a city-wide study in Louisville, KY. Of 522 patients with COVID-19 pneumonia, 219 (41.9%) were critically ill. Among critically ill patients, the median age was 60 years; 53% were male, 55% were White and 32% were African American. Of all critically ill patients, 52% had ARDS, and 38% of these had severe ARDS. Of the 25% of patients who were weaned off IMV, those with severe ARDS were weaned within eleven days versus five days for those without severe ARDS, p = 0.023. The overall mortality for critically ill patients was 22% versus 1% for those not critically ill. Furthermore, the 14-day mortality was 31% for patients with severe ARDS and 12% for patients without severe ARDS, p = 0.019. Patients with severe ARDS versus non-severe ARDS needed twice as long to wean off IMV (eleven versus five days) and had double the 14-day mortality of patients without severe ARDS.

Background Manual prone positioning has been shown to reduce mortality among patients with moderate to severe acute respiratory distress syndrome, but it is associated with a high incidence of pressure injuries and unplanned extubations. This study investigated the feasibility of safely implementing a manual prone positioning protocol that uses a dedicated device. Review of Evidence A search of CINAHL and Medline identified multiple randomized controlled trials and meta-analyses that demonstrated both the reduction of mortality when prone positioning is used for more than 12 hours per day in patients with acute respiratory distress syndrome and the most common complications of this treatment. Implementation An existing safe patient-handling device was modified to enable staff to safely perform manual prone positioning with few complications for patients receiving mechanical ventilation. All staff received training on the protocol and use of the device before implementation. Evaluation This study included 36 consecutive patients who were admitted to the medical intensive care unit at a large academic medical center because of hypoxemic respiratory failure/acute respiratory distress syndrome and received mechanical ventilation and prone positioning. Data were collected on clinical presentation, interventions, and complications. Sustainability Using the robust protocol and the low-cost device, staff can safely perform a low-volume, high-risk maneuver. This method provides cost savings compared with other prone positioning methods. Conclusions Implementing a prone positioning protocol with a dedicated device is feasible, with fewer complications and lower costs than anticipated.

In patients with acute respiratory distress syndrome (ARDS), prone positioning improves oxygenation but has no impact on mortality, except perhaps in those with Simplified Acute Physiology Score (SAPS) II >50. Level of evidence: 1+ (SR based on small RCTs, conducted prior to ARDSNet – subsequent change in practice)

Abstract Background: Prone positioning has demonstrated decreased mortality in severe acute respiratory distress syndrome (ARDS) patients. The aim of this study was to investigate the effect of prone positioning in patients with influenza pneumonia-related severe ARDS. Methods: This retrospective study includes eight tertiary referral centers. All the patients with influenza pneumonia induced severe ARDS and receiving prone positioning were enrolled. Demographic data, laboratory data, treatment record, ventilator setting data and outcomes were collected. PaO2 responders were defined as the PaO2/FiO2 ratio increasing by ≥20% or ≥20 mm Hg, while PaCO2 responders were defined as PaCO2 decreasing by ≥1 mm Hg after prone positioning for one day. Results: Sixty-five patients receiving prone positioning were enrolled, with 37 (57%) were PaO2 responders and 33 (51%) were PaCO2 responders. Mortality rates were not significantly different between responders and non-responders. PaCO2 responder survivors had significantly shortened length of stay at the ICU (21.0 ± 13.5 vs. 31.7 ± 18.5 days, P = 0.038) and hospital (30.2 ± 16.6 vs. 43.0 ± 16.3 days, P = 0.013) than did non-responders. Multivariate analysis revealed younger age (odds ratio 0.903, 95% confidence interval 0.824-0.989; P = 0.028) and higher PaCO2 level before prone positioning (odds ratio 1.121 confidence interval 1.020-1.231; P = 0.017) were the predictors of PaCO2 responders. Conclusions: In this multicenter retrospective cohort study of influenza pneumonia patients with severe ARDS receiving prone positioning, PaCO2 responders had modestly better clinical outcomes. Younger age and higher PaCO2 level before prone positioning were the predictors of PaCO2 responders.
