Abstract:
Objective To explore the effect of static air cushion at different intervals on preventing from pressure ulcers in bedridden patient .Methods One hundred patients in the department of orthopedic were chosen through the convenience sampling and self-controlled.The patients were supine , and the computer pressure sensor ( Xsensor manometry carpet ) was tiled under the body of patients .The average pressure peaks in the two lateral heel and sacrococcygeal were respectively measured after 2 h of lying ordinary mattress and 2, 3, 4 h of lying static air cushion , and the integrity of skin and the incidence of pressure ulcer were monitored during patients’ stay in bed.Results After 2 h of lying ordinary mattress , the cases of I stage pressure ulcer were 3 cases including 1 case of left heel and 2 cases of sacrococcygeal , and the incidence rate of pressure ulcer was 3%.After 2, 3, 4 h of lying static air cushion, the incidence of pressure ulcer in patients was not found , and the integrity rate of skin was 100%.After 2 h of lying ordinary mattress and static air cushion , the average pressure peaks were respectively (185.03 ±11.34), (69.13 ±9.64) mmHg in the left heel, and were (176.03 ±18.64), (76.40 ±11.52) mmHg in the right heel, and were (253.03 ±28.64), (100.23 ± 18.36)mmHg in the sacrococcygeal, and the differences were statistically significant (t =7.126,6.287, 4.235, respectively;P<0.05).No differences were found in the change of average pressure peaks in the two lateral heel and sacrococcygeal after 2, 3, 4 h of lying static air cushion ( F =5.863, 3.128, 4.852, respectively;P>0.05).Conclusions Static air mattress can effectively reduce vertical pressure on the surface of pressed parts in the bedridden patients , and the interval time of turning over can be prolonged to 4 h every time, and which can reduce the patients ’ pain caused by frequently turning over but also reduce the nurses ’ labor intensity .
