Comparison of different lying style in the prevention of pressure ulcer

Abstract

Objective Effect of different lying style on the prevention of pressure ulcer was compared in this study. Methods Braden scale was used to assess the risk factors of pressure ulcer in patients with consciousness and motor function handicap. 203 patients with marks under 12 was randomized into the observation group (102 cases) and the control group (101 cases). Patients in the observation group lied on their backs or with alternation of lateral recumbent position of 20～30°. The control group adopted lateral recumbent position of 90° with alternation of lying on their backs. The effect of different lying style on the prevention of pressure ulcer was compared. Results 97 patients in the observation group received apparent effect in the prevention of pressure ulcer (95.09%). While only 86 patients in the control group got significant effect (85.15%), which was statistically different from that of the observation group (P<0.05). Conclusion The style of lying on their backs or with alternation of lateralrecumbent position of 20～30° was more effective than that of lateral recumbent position of 90° with alternation of lying on their backs in the prevention of pressure ulcer.
