Comparative study on transport devices relieving pressure injury during long-distance referral of critical patients / 医疗卫生装备

ABSTRACT

Objective To investigate the effect of long-distance referral on pressure injury in critically ill patients,and to explore the effectiveness of transport devices in reducing the risk of skin pressure injury.Methods Totally 97 patients hospitalized from July 2015 to June 2016 were enrolled as the subjects after long-distance referral,of whom,52 ones from July to December 2015 were selected into a control group applying common sponge mattress and the remained 45 ones from January to June 2016 were chosen into an experimental group using inflatable mattress during the referral.The two groups were compared after the referral on the incidence rates of pressure injury and its early symptoms.Results The experimental group had the incidence rate of early symptoms being 8.9％,which was statistically different from that (42.3％) in the control group (P=0.00,x2=13.73).The incidence rate of pressure injury was 6.7％ in the experimental group,which was significantly lower than that (34.6％) in the control group (P=0.000,Z=-7.849).Conclusion There is high risk for pressure injury during long-distance referral of critical patients,and proper transport device has to be involved in to lower the risk effectively.
