The design and application of a bleeding alarm bandage for maintenance hemodialysis patients
Objective To design and produce a bleeding alert bandage and investigate its effectiveness in patients undergoing hemodialysis.Methods The bleeding alert bandage consists of elastic bandage,monitoring element and monitoring box.A convenience sampling method was used to select patients who received regular hemodialysis treatment in the blood purification center of a tertiary A comprehensive hospital in Anhui Province from January 2021 to June 2021.These patients were randomly assigned into an experimental group and a control group,with 40 cases in each group.Patients in the control group were inspected every 30 min by traditional method.Patients in the experimental group were monitored in real-time with a bleeding alert bandage in addition to the 30 min rounds.The detection rate,incidence,and volume of bleeding at the puncture site were compared in 2 groups of patients.Results The incidence of bleeding from the puncture sites was 17.00%in the experimental group and 25.25%in the control group,with statistical significance(x2=8.170,P=0.004).The incidence of bleeding for severe bleeding from puncture sites was 1.50%in the experimental group and 11.50%in the control group,with statistical significance(x2=32.910,P<0.001).The bleeding detection rate from puncture sites was 94.12%in the experimental group and 89.11%in the control group,with no statistical difference(x2=1.261,P=0.262).The detection rate for moderate bleeding from puncture sites was 100%in the experimental group and 85.37%in the control group,with statistical significance(x2=6.170,P=0.013).Additionally,the bleeding volume from the puncture site was 1.29(0.88,1.74)g in the experimental group and 2.77(1.60,4.77)g in the control group,with statistical significance(Z=-5.825,P<0.001).The moderate bleeding volume from the puncture site was 1.49(1.27,1.81)g in the experimental group and 1.92(1.52,2.44)g in the control group,with statistical significance(Z=-2.835,P=0.005).Conclusion The bleeding alert bandage is effective in real-time monitoring and alerting of bleeding at the puncture sites during hemodialysis,which can help reduce the incidence of blood seepage,improve the detection rate of blood seepage,reduce the amount of bleeding and improve the safety of dialysis treatment.
