Prone Positioning Carries a Real Skin Injury Burden in ARDS Care
Therapeutic prone positioning has become a standard maneuver in severe acute respiratory distress syndrome because it can improve oxygenation and redistribute lung stress. The same posture that helps gas exchange also creates prolonged, concentrated pressure over the face, chest, iliac crests, knees, and other anterior surfaces. In mechanically ventilated patients, especially those who remain immobilized for long periods, the skin and subcutaneous tissue can be compressed against hard surfaces while moisture, edema, vasopressor exposure, and adhesive devices add further insult.
Pressure injury prevention in this setting is not a cosmetic issue. It is a bedside safety problem that affects airway access, facial integrity, device tolerance, nursing workload, and the ability to continue proning without interruption.
Eight Studies, One Consistent Direction
This systematic review followed PRISMA 2020 and Joanna Briggs Institute guidance and was prospectively registered in PROSPERO under CRD42023442604. Searches ran across PubMed, CINAHL, Web of Science, Scopus, the Cochrane Library, and grey literature from inception through June 2025. The review included adult, mechanically ventilated patients undergoing therapeutic prone positioning and focused on interventions designed to prevent pressure injuries.
Eight studies met inclusion criteria. Their designs were heterogeneous, which prevented quantitative pooling and led investigators to use a Synthesis Without Meta-analysis approach. The interventions were also mixed, but the same broad categories kept reappearing: prophylactic dressings, repositioning and support devices, and bundled care protocols that combined multiple preventive steps.
The signal across studies ran in the same direction. Most preventive strategies were linked with lower pressure injury incidence, with the clearest benefit seen in facial and other anterior anatomical regions.
Why Facial and Anterior Injuries Cluster in the Prone Position
The face is uniquely vulnerable during prone ventilation because it is both load-bearing and difficult to monitor continuously. ETT fixation, nasogastric tubes, oxygen interfaces, and padding all compete for limited surface area. Even modest misalignment can produce focal pressure over the cheeks, chin, forehead, ears, and nasal bridge. When proning sessions are prolonged, capillary perfusion falls below the threshold needed to maintain tissue viability, and microvascular injury can progress quickly in critically ill patients with edema, shock, or impaired nutrition.
The review’s findings make clinical sense. Preventive dressings reduce friction and shear while spreading force over a wider area. Support devices can offload vulnerable points and improve head positioning. Repositioning, when performed in a structured way, prevents the same tissue from being compressed for the entire prone interval. These measures do not eliminate mechanical load, but they reduce the intensity and duration of injury-producing stress.
Bundles Outperformed Isolated, Unstructured Care
A clear pattern emerged from the studies: preventive measures worked best when they were embedded in standardized protocols supported by staff training and multidisciplinary coordination. In practice, that means proning teams that do not rely on improvisation at the bedside. They use predefined steps for pad placement, skin checks, turning sequence, device protection, and reassessment after each repositioning.
This matters because prone ventilation is a high-coordination intervention. Respiratory therapists, nurses, physicians, and sometimes wound-care specialists have to move in sync while maintaining ventilator safety, secure lines, and preserve hemodynamics. Without a protocol, prevention often becomes inconsistent from shift to shift. With a protocol, the same checks happen every time, and small deviations are corrected before they evolve into full-thickness tissue damage.
A dressing applied correctly before the turn is more useful than a rescue response after erythema appears.
What the Review Supports at the Bedside
The evidence base remains small, but the direction is practical. Prophylactic dressings, protective devices, and bundled protocols appear to reduce pressure injury risk in prone, mechanically ventilated adults. The strongest bedside implication is not that one product alone will solve the problem. It is that prevention should begin before the patient is turned and continue throughout every prone cycle.
For intensive care teams, that means treating skin protection as part of the proning order set rather than an optional add-on. Facial padding, careful device management, scheduled skin assessment, and trained staff should be integrated into the same workflow that supports oxygenation targets and ventilator management. In a patient population already exposed to severe hypoxemia, vasopressor use, sedation, and immobility, preventable skin breakdown can become another source of avoidable morbidity.
The review also supports closer multidisciplinary coordination. Wound prevention in this context depends on shared responsibility: the respiratory team protects the airway, nursing monitors pressure points, and the broader ICU team maintains hemodynamic stability and communicates any need to shorten or modify the prone session.
Limits of the Evidence and the Need for Standardized Trials
The review’s conclusions are encouraging, but the evidence base is still constrained by heterogeneity. The eight included studies varied in design, intervention type, and likely in how pressure injuries were defined or monitored. That prevented meta-analysis and limits confidence in any single preventive approach as a universal standard. The review also cannot answer whether one dressing type, one device, or one exact bundle is superior across all ICU settings.
A bigger problem is comparability. Proning duration, patient severity, staffing ratios, and local skin-care practice likely influenced outcomes, yet those variables are not uniform across studies. Future research will need more standardized definitions, clearer reporting of pressure injury location and severity, and direct comparisons between bundled strategies and usual care.
Even so, the clinical direction is hard to ignore: prone positioning should not be separated from pressure injury prevention. In critically ill adults who need the maneuver to survive severe respiratory failure, skin protection has to be built into the proning protocol from the start, not added after the first injury appears.
