Abstract

Clinical studies have found that patients with acute respiratory distress syndrome (ARDS) account for approximately 5% of all hospitalized patients subjected to mechanical ventilation. Most studies have shown that patients with mild ARDS (PaO2/FiO2 200–300) represent only 25% of the cases, while the remaining 75% correspond to patients with moderate or severe ARDS (Estoben, etal., 2008)  Patients with acute pulmonary complications may benefit from prone therapy, which improves the ventilation/perfusion ratio (Sud et al., 2014). Relative to the supine position, rotating the patient while in the prone position can assist with moving the heart and lung tissue so that secretions and debris can be removed in order to allow expansion of the alveoli, and minimization of alveolar stretch and strain (Berry, 2015). Such positioning improves oxygenation sufficient that it can reduce the risk of mortality by hypoxia in patients suffering from acute pulmonary distress syndrome (Sud et al., 2014).

            In a systematic review and meta-analysis of 11 randomized controlled trials, prone positioning was found to significantly reduce mortality with a risk ratio of 0.74 (95% CI 0.59-0.95) relative to supine positioning (Sud et al., 2014). The study found that improvements in oxygenation in the prone group exceeded those in the supine group, although the risk of forming pressure ulcers, obstruction of the endotracheal tube, and dislodgement of the thoracotomy tube were also higher in the prone group. Another study of 466 patients with acute respiratory distress syndrome found statistically significant improvement in the mortality rates at 28 days and 90 days among prone patients relative to supine patients (Guérin et al., 2013). Prone therapy has thus been found to significantly benefit patients with acute pulmonary complications.

            In the past, however, manually rotating patients to the prone position was often difficult, especially if the individual had conditions such as aortic rupture, prominent external fixation, obesity, or instable pelvic fractures (Kim & Mullins, 2016)
