Abstract:
Objective:To explore the application effect of pressure relief double knee pad in pressure injury in critically ill patients.Methods:A total of 635 patients who were admitted to Intensive Care Unit of Taizhou Hospital in Zhejiang Province from June 2020 to April 2021 were selected as the research objects by the convenient sampling method. They were divided into the control group ( n=315) and the experimental group ( n=320) by the random number table method. On the basis of the conventional lying position, patients in the control group placed the R-shaped pads on the back of the shoulder to the top of the pelvis, while patients in the experimental group slightly bent their lower limbs on the basis of the control group and placed it on the self-designed pressure relief double knee pad. The incidence of pressure injury, pressure index of sacrum and heel skin, the non-displacement rate of support appliances and the incidence of deep vein thrombosis (DVT) in the two groups were evaluated. Results:The incidence of pressure injury of patients in the experimental group was 0.63% (2/320) , which was lower than 3.17% (10/315) in the control group, and the difference was statistically significant ( P<0.05) . The pressure indexes of the sacrum and heel of the experimental group were respectively (66.10±13.43) and 0 mmHg, which were lower than (75.08±12.03) and (22.26±6.20) mmHg of the control group, and the differences were statistically significant ( P<0.05) . The non-displacement rate of support appliances in the experimental group was 89.62% (190/212) , which was higher than 52.63% (100/190) in the control group, and the difference was statistically significant ( P<0.05) . There was no statistically significant difference in the incidence of VTE between 2 groups ( P>0.05) . Conclusions:The use of pressure relief double knee pads can reduce the incidence of pressure injuries, the pressure of the skin of the sacrum and heel and increase the non-displacement rate of support appliances, which is worthy of clinical application.
