Effect of prone ventilation at different angles on oxygenation response and pressure injury in elderly patients with respiratory distress syndrome
Objective To observe the effects of 0° prone position ventilation and 30° inclined prone position ventilation on oxygenation response and pressure injury in elderly patients with respiratory distress syndrome.Methods 92 elderly patients with respiratory distress syndrome who were admitted to the geriatric department from February 2020 to February 2024 and planned to undergo prone mechanical ventilation were studied.Randomly divide patients into a 0° prone position group and a 30° prone position group,with 46 patients in each group.Compare the average oxygenation index of two groups of patients after lying prone on days 1,2,3,5,and 7,and compare the total incidence and location of pressure injury in the two groups.Results After excluding missing medical records,44 patients in the 0° prone position group and 45 patients in the 30° prone position group completed the study.There was no statistically significant difference in oxygenation index between the two groups after lying prone on days 1,2,3,5,and 7.There was no statistically significant difference in the 28 day mortality rate between the two groups,and there was no statistically significant difference in the duration and frequency of prone position ventilation on days 1,2,3,5,7,and the average daily ventilation.A total of 20 patients in the 0° prone position group experienced 53 pressure injuries,while 11 patients in the 30° prone position group experienced 25 pressure injuries.The difference in incidence between the two groups was statistically significant(χ2=4.326,P=0.037).Conclusion Both 0° and 30° prone position ventilation can improve oxygenation in elderly patients with respiratory distress syndrome.30° inclined prone position is beneficial for reducing the incidence of pressure injuries,but comprehensive measures and key protection measures still need to be taken for areas with high incidence of pressure injuries such as the face.
