Preventing Pressure Injury in Prone Positioning


2022-12-02T15:00:00.0000000Z

Prone positioning, which involves turning a patient over so that they lie in a chest-down, is a well-established intervention for ARDS. It has been shown to improve oxygenation and prevent ventilator-induced lung injury due to the more uniform distribution of lung stress and strain1,2

While prone positioning, or lying the patient face-down (see Fig. 1), has been recommended since as far back as 19743 for treating ARDS, the recent COVID-19 pandemic has driven an increase in the necessity for and utilisation of prone positioning as a method to improve life-threatening low oxygen levels.

The latest guidelines4 suggest that prone sessions should last for more than 16 hours each day to take advantage of physiological changes that can result in improved oxygenation.

However, managing patients in the prone position for such prolonged periods places the patients at significant risk of complications, including pressure injury5. Such injuries can lead to a protracted hospital stay, patient suffering, possible surgical intervention, and increased costs of care6.

When caring for patients in the prone position, caregivers are challenged to prevent pressure injuries developing over body areas such as the face, breast region, genitals, knees and toes (Fig. 2), not typically at risk when the patient is managed supine, but at high risk when patients are in the prone position.

Selecting the right support surface is therefore an important component to be deployed with this high risk patient population.

The Nimbus Professional alternating pressure mattress replacement system includes ‘Zoned wound valve technology’ (Fig. 3 and 4), designed to specifically help off-load vulnerable body areas, providing an appropriate support surface solution when prone positioning is required.

This enables the caregiver to off-load selected cells under the under parts of the body at specific risk, while the head section can be deflated to give flexibility to caregivers in managing the patients head and airway.

The Nimbus Professional mattress also offers the additional benefit of a fully-welded cover constructed from one of the toughest medical fabrics available7.

Extensive clinical studies8-15 on the Nimbus product range consistently demonstrate excellent outcomes for the most vulnerable patients or those with existing wounds.
