Effects of prone positioning and turning duration on burn patients with acute respiratory distress syndrome receiving mechanical ventilation
Objective To explore the effect of different prone positions and turning durations on the therapeutic efficacy in burn patients with acute respiratory distress syndrome(ARDS)receiving mechanical ventilation.Methods The 41 burn patients with ARDS receiving mechanical ventilation in the hospital from June to December 2021 were selected for the control group.They were placed in prone and supine positions for 2 hours each and alternately turned over 3 times,with a total of 6 h in the prone position.Additionally,38 patients with the same conditions admitted from January to June 2022 were selected for the observation group.They were placed in prone position for 4 hours → supine for 2 h → prone for 4 h → supine,totaling 8 h of prone position.The differences in the blood gas analysis results,length of hospital stay,and Braden Scale scores between the two groups were compared within one week.Results On the 7th day after adjusting the prone position and turning duration,the partial pressure of oxygen(PaO2)and oxygenation index(PaO2/FiO2)of patients in the observation group were higher than those in the control group,the differences were statistically significant(P<0.05);the partial pressure of carbon dioxide in artery(PaCO2)of patients in the observation group was lower than that in the control group,the difference was statistically significant(P<0.05);the length of hospital stay of patients in the observation group was shorter than that in the control group,the Braden scores of patients were higher than those in the control group,and the differences were statistically significant(P<0.05).Conclusion Turning over alternately between 2 hours of supine position and 4 hours of prone position twice,totaling 8 hours of prone position,can improve patients'blood gas indexes,alleviate pressure injury of skin,and shorten hospital stay.
